Purpose: Limited research has examined the combined effects of psychosocial and material adversities experienced in childhood during adolescence, a sensitive period of rapid social, emotional, and cognitive development. We investigated the interaction effect of adverse childhood experiences (ACEs) and socioeconomic circumstances (SECs) during childhood on emerging self-reported depressive symptomatology among 13-year-old Portuguese adolescents., Methods: We utilized data from 4,280 participants in the Generation XXI birth cohort, collected during the baseline (2005-2006), third (2016-2017), and fourth waves (2018-2020). Adjusted odds ratios and 95% confidence intervals (CIs) were obtained from binary logistic regression analyses to estimate the likelihood of depressive symptoms based on exposure to ACEs and adverse family SECs. The interaction effect of ACEs and SECs was evaluated in terms of departure from additive and multiplicative models., Results: Adolescents who reported experiences of abuse, school-related problems, and household dysfunction, as well as those from less advantaged family SECs at age 10, were more likely to report moderate to severe depressive symptoms at age 13, compared to their more affluent counterparts. We observed a significant additive interaction between low household income and abuse in the development of moderate to severe depressive symptoms [relative excess risk due to interaction, 0.69, 95% CI: 0.11, 1.26]. This interaction remained statistically significant on a multiplicative scale [OR = 1.61, 95% CI: 0.99, 2.69]., Discussion: ACEs and low family SECs during the first decade of life are associated with an elevated risk of moderate to severe depressive symptoms in adolescence., (Copyright © 2024 Society for Adolescent Health and Medicine.

The study aimed to describe trajectories of free sugar (FS) intake, its main sources and the associations with socio-economic status (SES) in Portuguese children/adolescents evaluated at 4, 7, 10 and 13 years of age from Generation XXI birth-cohort. Dietary intake was assessed through 3-day food diaries ( n 5268). Added sugar intake was estimated following a systematic methodology, and FS was based on the WHO definition. A mixed-effects model with linear and quadratic terms for time was used to estimate FS trajectories and its association with SES, adjusting for children's sex, age, BMI and SES. The FS mean intake (g/day) was 37, 47, 51 and 48 at 4, 7, 10 and 13 years, respectively. FS intake increased 4·6 g/year (CI 95 %: 4·20, 5·04), but velocity decreased by 0·3 g/year 2 until 13 years. At all ages, the main food source was sweets. Some item's consumption declined (sweets 25-21 % and yoghurts 22-7 %) as children grew older. Inversely, soft drink intake increased (9-18 %). Boys and children from younger mothers had higher FS intake, whereas higher maternal-SES was associated with lower children's FS intake: occupational status ( β = -3·5; 95 % CI: -4·97, -1·94), years of education ( β = -3·7; 95 % CI: -4·93, -2·40) and household income ( β = -4·9; 95 % CI: -6·50, -3·27). The FS trajectories were similar by SES categories but different by obesity status (interaction term β = -1·04; CI 95 % (-1·50, -0·59)). An increasing FS trajectory during childhood is mainly driven by an increasing intake of soft drinks and nectars. The FS trajectory pattern did not change according to SES categories, but children's FS intake was always higher when their mothers had a lower SES.

Objectives: To develop an allometric body mass index (ABMI) reference that adjusts the weight in relation to height, taking into account the changes during development (MULT ABMI reference), and to compare it with international BMI references., Methods: The MULT ABMI reference was constructed through the LMS method, calculated with 65 644 ABMI observations of 17 447 subjects aged 5-22 years, from the United Kingdom, Ethiopia, India, Peru, Vietnam, Portugal, and Brazil. The M, S, and L curves of the MULT ABMI reference were compared with the curves of the MULT, World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF), and Dutch Growth Study (DUTCH)., Results: The greater differences in the M curve between MULT ABMI and WHO, CDC, IOTF, DUTCH, and MULT BMI references were around puberty (138 to 150 months for boys; 114 to 132 for girls). MULT ABMI presented S values similar to IOTF and DUTCH BMI references for boys 60 to 114 months and then became higher, approaching the MULT BMI S values from 198 to 240 months. For girls the MULT ABMI S values were close to the IOTF, CDC, and DUTCH from 60 to 110 months, and then became higher, approaching the MULT BMI S values until 240 months., Conclusion: MULT ABMI presented an advantage in comparison to the existing BMI references because it takes into account the growth changes during puberty and is a new option to assess the nutritional status of multiethnic populations., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 de Oliveira et al.

Increased cardiometabolic risk is associated with abnormalities in blood biomarkers profile and adiposity measurements. Some substances found in the food matrix and the environment, called endocrine-disrupting chemicals, may impair cardiometabolic health in the early and later stages of life. Bisphenol A (BPA) is a food contaminant that migrates from food contact materials and may act as an endocrine disruptor, negatively affecting human health. The present work aims to longitudinally assess the association between BPA exposure and cardiometabolic outcomes, considering data from Portuguese population-based birth cohort Generation XXI. Blood insulin (0.06stdβ; 95 %CI:0.03,0.09) and insulin resistance (0.05stdβ; 95 %CI:0.02,0.08) presented a significant longitudinal association with BPA daily exposure after adjustment for important variables and energy. The same findings were observed for fat mass (0.03stdβ; 95 %CI 0.01,0.06) and waist circumference (0.06stdβ; 95 %CI:0.04,0.08). For z-BMI, a significant cross-sectional (0.03stdβ; 95 %CI:0.01,0.04) and longitudinal (0.02stdβ; 95 %CI:0.00,0.04) association was found. This was the first study assessing the association between BPA exposure and health outcomes from childhood to adolescence. We found an association between BPA exposure and increased blood insulin level, insulin resistance, fat mass percentage, waist circumference and z-BMI. Our results point to the need to reduce exposure to BPA in the early stages of life., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Given the high prevalence of multiple-choice examinations with formula scoring in medical training, several studies have tried to identify other factors in addition to the degree of knowledge of students which influence their response patterns. This study aims to measure the effect of students' attitude towards risk and ambiguity on their number of correct, wrong, and blank answers. In October 2018, 233 3rd year medical students from the Faculty of Medicine of the University of Porto, in Porto, Portugal, completed a questionnaire which assessed the student's attitudes towards risk and ambiguity, and aversion to ambiguity in medicine. Simple and multiple regression models and the respective regression coefficients were used to measure the association between the students' attitudes, and their answers in two examinations that they had taken in June 2018. Having an intermediate level of ambiguity aversion in medicine (as opposed to a very high or low level) was associated with a significant increase in the number of correct answers and decrease in the number of blank answers in the first examination. In the second examination, high levels of ambiguity aversion in medicine were associated with a decrease in the number of wrong answers. Attitude towards risk, tolerance for ambiguity, and gender did not show significant association with the number of correct, wrong, and blank answers for either examination. Students' ambiguity aversion in medicine is correlated with their performance in multiple-choice examinations with negative marking. Therefore, it is suggested the planning and implementation of counselling sessions with medical students regarding the possible impact of ambiguity aversion on their performance in multiple-choice questions with negative marking., (© 2024.

Purpose: To describe a series of patients with hereditary transthyretin amyloidosis (ATTRv) with vitreous amyloid and to study the efficacy and safety of pars plana vitrectomy (PPV) for its treatment., Methods: Retrospective study of 266 patients with ATTRv due to Val30Met mutation submitted to PPV for vitreous amyloid, with a minimum 3-month follow-up. Indications for surgery were disabling myodesopsia or 2 lines loss in visual acuity. Only the first operated eye was considered for analysis., Results: Male patients were operated at younger age (51.0 vs 53.6, p<0.001). Best-corrected visual acuity improved from 0.38 to 0.89 (decimal scale, p<0.001). Preoperative glaucoma was associated with lower gain in visual acuity (p<0.001). During the follow-up, 69%, 22% and 1% developed new onset glaucoma, retinal angiopathy or retinal detachment, respectively, and 36% required cataract surgery. PPV was also required in the fellow eye in 57%. ATTRv-related death occurred in 27%, 9.3 95%CI 8.0-10.7 years after PPV., Conclusion: Vitreous opacities are frequently the first symptomatic manifestation of ocular amyloidosis. Moreover, they may be a marker of mortality. Vitrectomy is a safe and effective treatment, but these patients require long-term follow-up to monitor the development or worsening of glaucoma or retinal angiopathy., Competing Interests: Disclosure of interest: The authors report no conflict of interest.

We aimed to examine the relationship between lifetime exposure to adverse childhood experiences (ACEs) during the first decade of life and recent pain features reported in early adolescence. We conducted a prospective study using data from 4564 adolescent Generation XXI birth cohort participants recruited in 2005-2006. Adverse childhood experiences were reported by children at ages 10 and 13 years using a 15-item questionnaire. Recent pain features (e.g., any pain, pain sites, recurrent pain intensity, and recurrent pain duration) were measured using structured questionnaires, including the Luebeck pain screening questionnaire at age 13. Using hierarchical binary and multinomial logistic regression analyses with progressive adjustments for confounders, we estimated the associations [adjused odds ratios (aOR) with their 95% confidence intervals (95% CI)] between exposure to ACEs at 10 and pain features at 13 years. The study revealed a statistically significant association between exposure to ACEs reported at age 10 and any pain experienced at age 13 (OR = 1.09; 95% CI [1.07, 1.12]). Even after accounting for the newly reported ACEs at age 13, the association with ACEs at age 10, remained significant (aOR = 1.11 [95% CI, 1.08-1.14]). Consistent patterns were observed when the number of pain sites, recurrent pain intensity, or recurrent pain duration were used as outcome variables instead of any pain at age 13. Adverse childhood experiences occurring during the first decade of life predict the onset of pain features during early adolescence. Consequently, childhood exposure to adversity should be considered a pivotal initial exposure in a pathway leading to chronic pain later in life., (© 2024 The Authors.

This cross-sectional study aims to describe and compare energy, nutrient intake and food consumption according to eating location and by age groups using data from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015/2016). Dietary intake was estimated by two non-consecutive days of food diaries (children)/24-h recalls (other age groups), and four eating location categories were defined according to the proportion of meals consumed at out-of-home locations: Home (at least 80 % of meals at home), Other Homes , School or Work and Restaurants and Other Places . The majority of meals (69·1 %) were consumed at home. Meals were also often taken at school by children and adolescents and in restaurants and similar outlets by adults and elderly. Children and adolescents in the School or Work category ate more fruit, vegetables and pulses and cereals and starchy tubers, whereas adults in this category ate more red and processed meats, sugar-sweetened beverages and sweets. Compared with Home category, Restaurants and Other Places was associated with worse diet adequacies among children ( β = -1·0; 95 % CI = -2·0, -0·04), adolescents: ( β = -2·4; 95 % CI = -3·2, -1·5) and adults ( β = -1·3; 95 % CI = -1·6, -1·0) reflecting higher intakes of energy, fat, trans -fatty acids and SFA, and Na. The elderly consumed more free sugars and fat when eating out of home in general. Overall, findings reflect important variation in nutrient profiles by eating location, with meals taken at school or work contributing to higher consumption of nutrient-dense foods and those taken in restaurants and other similar settings implying higher consumption of energy-dense foods.

This study aimed to provide a comprehensive picture of the life expectancy of dogs in Portugal, focusing on the impact of diverse factors including breed, sex, size, and skull shape. The final dataset, gathering data from the national registry database, consisted of 278,116 dogs with confirmed deaths. The mean lifespan at birth for all the dogs was around 8.91 years, with the female dogs tended to have a similar lifespan to male dogs. The analysis of life expectancy at birth for the 20 most common non-Portuguese breeds and 10 Portuguese breeds revealed that Yorkshire Terriers had the highest life expectancy (10.89 years) and French Bulldogs the lowest (6.27 years). Size and cephalic index were found to be influential factors, with large brachycephalic breeds exhibiting shorter life expectancies and smaller, mesocephalic breeds experiencing longer lifespans. Additionally, the cephalic index had a more substantial impact on life expectancy compared to body size. These findings enhance the understanding of the factors influencing canine longevity and aid in developing strategies to improve the health and lifespan of companion dogs.

Most instruments measuring nutrition literacy evaluate theoretical knowledge, not necessarily reflecting skills relevant to food choices. We aimed to develop and validate a photograph-based instrument to assess nutrition literacy (NUTLY) among adults in Portugal. NUTLY assesses the ability to distinguish foods with different nutritional profiles; from each of several combinations of three photographs (two foods with similar contents and one with higher content) participants are asked to identify the food with the highest energy/sodium content. The NUTLY version with 79 combinations, obtained after experts/lay people evaluations, was applied to a sample representing different age, gender and education groups (n = 329). Dimensionality was evaluated through latent trait models. Combinations with negative or with positive small factor loadings were excluded after critical assessment. Internal consistency was measured using Cronbach's alpha and construct validity by comparing NUTLY scores with those obtained in the Medical Term Recognition Test and the Newest Vital Sign (NVS), and across education and training in nutrition/health groups. The cut-off to distinguish adequate/inadequate nutrition literacy was defined through ROC analysis using the Youden index criterion, after performing a Latent class analysis which identified a two-class model to have the best goodness of fit. Test-retest reliability was assessed after one month (n = 158). The final NUTLY scale was unidimensional and included 48 combinations (energy: 33; sodium: 15; α = 0.74). Mean scores (±standard deviation) were highest among nutritionists (39.9 ± 4.4), followed by health professionals (38.5 ± 4.1) and declined with decreasing education (p < 0.001). Those with adequate nutrition literacy according to NVS showed higher NUTLY scores (37.9 ± 4.3 vs. 33.9 ± 6.9, p < 0.001). Adequate nutrition literacy was defined as a NUTLY score≥35 (sensitivity: 89.3%; specificity: 93.7%). Test-retest reliability was high (ICC = 0.77). NUTLY is a valid and reliable nutrition literacy measurement tool., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

This study aimed to examine diet tracking from childhood to adolescence, using 4 time-points, and the influence of socioeconomic and individual characteristics in this transition. The sample included 6893 children from the Portuguese birth cohort Generation XXI with complete information on Food Frequency Questionnaire in at least one of the considered follow-ups. A Healthy Eating Index (HEI), previously developed to assess adherence to WHO's dietary recommendations, was applied at all ages (4, 7, 10 and 13y). The intraclass correlation coefficient (ICC) was used to analyse the tracking of diet quality. Linear mixed-effect models were performed to estimate the association of the child's socioeconomic and individual characteristics with the HEI score and respective trajectories over time. The overall diet quality decreased from childhood (22.2 ± 3.6 at 4y) to adolescence (18.2 ± 3.9 at 13y), with moderate tracking (ICC = 0.53), showing that children who start a healthy diet earlier might have a better diet quality as time goes by. Children of older mothers (β = 0.079, 95%CI = 0.061-0.097) and with higher education (β = 0.203, 95%CI = 0.178-0.229) and a higher household monthly income (β = 0.024,95%CI = 0.007-0.041) had a higher diet quality over time. Besides family characteristics, the child's sedentary activities (β = -0.009, 95%CI = -0.014--0.003) negatively influence diet quality throughout life. In contrast, being a girl (β = -0.094, 95%CI = -0.132--0.056) and having higher sleep duration (β = 0.039, 95%CI = 0.015-0.064) are associated with a higher diet quality over time. The presence of dietary tracking from childhood to adolescence implies that promoting healthy eating habits during the first years of life is crucial for a healthier diet quality during late childhood and early adolescence, focusing on maternal and individual child characteristics., Competing Interests: Declaration of Competing interest None., (Copyright © 2024 The Authors.

Background: Early feeding practices have a critical role in the future not only in health but also in modulating eating habits. This study aimed to assess breastfeeding and complementary feeding practices and the nutritional status of Portuguese toddlers aged 0-36 months., Methods: EPACI Portugal 2012 is a cross-sectional study of a national representative sample. Trained interviewers collected data about early feeding practices and anthropometrics. Body mass index was classified according to World Health Organization criteria. Frequencies and survival analysis were used to characterize variables., Results: More than 90% of children were initiated breastfeeding, around 20% were exclusively breastfed for six months, and about 20% were breastfed at 12 months while complementary feeding was taking place. Exclusive breastfeeding was determined by maternal prepregnancy body mass index (HR 1.01; 95% CI 1.00, 1.03, P =.03) and low birth weight (HR 1.61; IC 95% 1.21, 2.15, P =.001) of the infants. About 90% were initiated complementary feeding between four and six months, and almost 10% were introduced to cow's milk before 12 months. In the second year of life, 83.2% and 61.6% of toddlers have already consumed nectars and sweet desserts, respectively. About one-third of Portuguese toddlers showed a body mass index z-score >1, and 6.6% were overweight/obese (z-score >2). No association was found between the duration of breastfeeding or timing of complementary feeding and the body mass index z-score in children., Conclusions: Despite the low prevalence of exclusive breastfeeding at six months, Portuguese infants effectively comply with dietary recommendations during the first year of life. The transition to the family diet must be carefully made. There is a high prevalence of Portuguese toddlers at least at overweight risk. The duration of breastfeeding or timing of complementary feeding was not associated with the expression of overweight/obesity., (Copyright © 2024 The Authors.

Neuroticism is a personality trait associated with the risk of affective disorders and perinatal depression. We investigated the relationship between different levels of neuroticism, psychological characteristics, and depressive symptoms in a sample of pregnant women (N = 2631) who accessed the gynecology departments in the Puglia Region (Italy) from July 2020 to November 2022. Women were assessed for depressive symptoms and associated risk factors in their third trimester of pregnancy (T0) and after childbirth (T1), and followed-up at 6 months and 1 year after delivery if presenting signs of depression (T2-T3). The Edinburgh Postnatal Depression Scale (EPDS) was used to screen depressive symptoms, and neuroticism was assessed through the subscales of the NEO Five Factor Inventory. Standardized measures of resilience, coping strategies, partner attachment, and quality of life were also employed. Higher levels of neuroticism were significantly associated with: (a) higher scores on the EPDS; (b) higher anxiety in the experience of close relationships; (c) lower psychological wellbeing; (d) lower levels of resilience; (e) lower levels of active coping; and (f) higher levels of self-blame. Our findings may suggest that neuroticism is a specific associated factor of perinatal depression and should be routinely assessed in the clinical screening of pregnant women in order to promote an early referral to psychological or psychiatric support services.

Objectives: Assessing the accuracy of serological tests for SARS-CoV-2 was challenging due to the lack of a gold standard. This study aimed to estimate the accuracy of SARS-CoV-2-specific serological tests using Bayesian latent class models (BLCM) and compare methods with and without a gold standard., Study Design and Setting: In this study, we analyzed 356 samples-254 positives, ie, from individuals with a previous SARS-CoV-2 infection diagnosis, and 102 negatives, ie, prepandemic samples-using six different rapid serological tests and one laboratory assay. A BLCM was employed to concurrently estimate the sensitivity and specificity of all serological tests for the immunoglobulin (Ig) M and IgG antibodies specific for SARS-CoV-2. Noninformative priors were used. A sensitivity analysis was conducted considering three methods: 1) reverse transcription-polymerase chain reaction test (RT-PCR) as the gold standard, 2) BLCM with RT-PCR as an imperfect gold standard, and 3) frequentist latent class model (LCM). All analyses used software R version 4.3.0, and BLCM were fitted using package runjags using the software JAGS (Just Another Gibbs Sampler)., Results: The BLCM-derived sensitivity for IgM varied from 10.7% [95% credibility interval (CrI):1.9-24.6] to 96.9% (95% CrI: 91.0-100.0), with specificities ranging from 48.3% (95% CrI: 39.0-57.6) to 98.9% (95% CrI: 96.2-100.0). Sensitivity for IgG varied between 76.9% (95% CrI: 68.2-84.7) and 99.1% (95% CrI: 96.1-100.0), and specificity ranged from 49.9% (95% CrI: 19.4-95.8) to 99.3% (95% CrI: 97.2-100.0). LCM results were comparable to BLCM. Considering the RT-PCR as a gold standard underestimated the tests' sensitivity, particularly for IgM., Conclusion: BLCM-derived results deviated from those using a gold standard, which underestimated the tests' characteristics, particularly sensitivity. Although Bayesian and frequentist LCM approaches yielded comparable results, BLCM had the benefit of enabling credibility interval computation even when sample power is limited., Competing Interests: Declaration of competing interest Joana Pinto Costa reports that financial support was provided by the Fundação para a Ciência e Tecnologia.

Background and Aims: Bisphenol A (BPA), an endocrine disruptor widely used in food contact materials, has been linked to a worse health profile. This study intends to estimate the association between BPA exposure and cardiometabolic patterns at adolescence., Methods and Results: Data from the Portuguese population-based birth cohort Generation XXI at the age of 13 were used (n = 2386 providing 3-day food diaries and fasting blood samples). BPA exposure was measured in 24-h urine from a subsample (n = 206) and then predicted in all participants using a random forest method and considering dietary intake from diaries. Three cardiometabolic patterns were identified (normal, modified lipid profile and higher cardiometabolic risk) using a probabilistic Gaussian mixture model. Multinomial regression models were applied to associate BPA exposure (lower, medium, higher) and cardiometabolic patterns, adjusting for confounders. The median BPA exposure was 1532 ng/d, corresponding to 29.4 ng/kg/d. Adolescents higher exposed to BPA (compared to medium and lower levels) had higher BMI z-score (kg/m 2 ) (0.68 vs. 0.39 and 0.52, respectively; p = 0.008), higher levels of body fat (kg) (16.3 vs. 13.8 and 14.6, respectively; p = 0.002), waist circumference (76.2 vs. 73.7 and 74.9, respectively; p = 0.026), insulinemia (ug/mL) (14.1 vs. 12.7 and 13.1, respectively; p = 0.039) and triglyceridemia (mg/dL) (72.7 vs. 66.1 and 66.5, respectively; p = 0.030). After adjustment, a significant association between higher BPA and a higher cardiometabolic risk pattern was observed (OR: 2.55; 95%CI: 1.41, 4.63)., Conclusion: Higher BPA exposure was associated with a higher cardiometabolic risk pattern in adolescents, evidencing the role of food contaminants in health., (Copyright © 2024 The Author(s).

Objective: Episiotomy, defined as the incision of the perineum to enlarge the vaginal opening during childbirth, is one of the most commonly performed surgical interventions in the world. We aimed to determine if migrant status is associated with episiotomy, and if individual characteristics mediate this association. Methods: We analyzed data from the Bambino study, a national, prospective cohort of migrant and native women giving birth at a public hospital in mainland Portugal between 2017 and 2019. We included all women with vaginal delivery. The association between migrant status and episiotomy was assessed using multivariable multilevel random-effect logistic regression models. We used path analysis to quantify the direct, indirect and total effects of migrant status on episiotomy. Results: Among 3,583 women with spontaneous delivery, migrant parturients had decreased odds of episiotomy, especially those born in Africa, compared to native Portuguese women. Conversely, with instrumental delivery, migrant women had higher odds of episiotomy. Disparities in episiotomy were largely explained by maternity units' factors, and little by maternal and fetal characteristics. Conclusion: Our results suggest non-medically justified differential episiotomy use during childbirth and highlight the importance of developing evidence-based recommendations for episiotomy use in a country with a high frequency of medical interventions during delivery., Competing Interests: The authors declare that they do not have any conflicts of interest., (Copyright © 2024 Lorthe, Severo, Hamwi, Rodrigues, Teixeira and Barros.)

This study aimed to assess the potential stability of appetitive traits from childhood to early adolescence, identify groups of individuals with distinct trajectories for these traits, and explore their association with other child and family characteristics. Participants were 5040 children from the Generation XXI cohort. Appetitive traits were assessed with the Children's Eating Behaviour Questionnaire (CEBQ) at ages seven, 10, and 13 (eight subscales). Mixed-effect models estimated individual trajectories of appetitive traits and Gaussian mixture models identified groups following different trajectories (appetitive trait trajectory profiles). Appetitive traits showed moderate-to-high stability across the three ages (intra-class correlation coefficients:0.66-0.83); most of the variance observed across time were due to persistent individual differences rather than age-related changes. Six appetitive trait trajectory profiles were identified: 'Moderate appetite' (scores close to the average) (29% of children), 'Small to moderate appetite' (lowest food approach and emotional eating) (26%), 'Increasing appetite' (increasing food approach) (15%), 'Avid appetite' (highest food approach and lowest food avoidance) (12%), 'Smallest appetite' (highest food avoidance and low food approach) (10%), and 'Small appetite but increasing' (decreasing high food avoidance and Desire to Drink) (8%). In multinomial logistic regression, these profiles were associated with different child and family characteristics. Compared to children with a 'Moderate appetite' profile, those with higher BMI, who desired a thinner body, whose mothers were younger, had lower education, higher pre-pregnancy BMI (OR = 1.07; 95%CI:1.04,1.09), smoked during pregnancy (OR = 1.51; 95%CI:1.21,1.90), and used more restrictive feeding practices (OR = 1.79; 95%CI:1.57,2.03) had increased odds of belonging to the 'Avid Appetite'. In conclusion, distinct appetitive trait trajectory profiles emerged, differentiating individuals with avid and small appetites. These findings have implications for identifying children at higher risk for obesogenic profiles., Competing Interests: Declaration of competing interest The authors do not have any competing interest to declare., (Copyright © 2023.

Introduction: Component-resolved diagnosis (CRD) has been decisive in exploring the mechanisms of IgE sensitization, but the predictive ability to detect asthma has not been addressed. We aim to develop and evaluate the performance of a personalized predictive algorithm for asthma that integrates information on allergic sensitization using CRD., Methods: One thousand one hundred one twenty-five children from the Generation XXI birth cohort were randomly selected to perform a screening test for allergic sensitization and a subsample was characterized using CRD against 112 allergen components. Allergen components were analyzed using volcano plots and partial least squares (PLS) analysis. Logistic regression was performed to assess the associations between the obtained latent components (LC) and allergic outcomes (asthma, rhinitis, eczema) including other potential predictors used in previous asthma risk scores. The accuracy of the model in predicting asthma was assessed using Receiver Operating Characteristic (ROC) curve statistics., Results: In the PLS, the first LC was positively associated with asthma, rhinitis, and eczema. This LC was mainly driven by positive weights for Der p 1/2/23, Der f 1/2, and Fel d 1. The main components in the second LC were pollen and food allergens. History of early wheezing and parental allergy were included in the predictive model and the area under the curve improved to 0.82., Conclusions: This is the first approach to improve the clinical applicability of CRD by combining CRD and clinical data to predict asthma at 13 years. Sensitization to distinct allergen molecules seems relevant to improve the accuracy of asthma prediction models., (© 2023 European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

Dogs spontaneously develop mammary gland tumors (MGT) and exhibit striking similarities in clinical and epidemiological characteristics to human breast cancer (HBC). Descriptive and comparative analysis of HBC and canine MGT with a focus on evaluating similarities and geographical distribution were the aims of this study. HBC cases were obtained from North Regional Oncological Registry (RORENO) (2010-2015) and canine MGT cases from Vet-OncoNet (2019-2022). Analyses were performed based on published and well accepted classification systems (ICD-O-3.2 for humans and Vet-ICD-O-canine-1). Age-standardized incidence risks (ASIR) of Porto district municipalities were calculated using 2021 Portuguese census (INE) and data from the Portuguese animal registration system (SIAC). Among 7,674 HBC cases and 1,140 MGT cases, a similar age and sex distribution pattern was observed. Approximately 69.2% of HBC cases were between 40 and 69 years old, while 66.9% of MGT cases were diagnosed between 7 and 12 years old (mean age of 9.6 years, SD = 2.6). In women, Invasive breast carcinoma (8500/3) was the most common histological type ( n = 5,679, 74%) while in dogs it was the Complex Carcinoma (8983.1/3) ( n = 205, 39%). Cocker and Yorkshire Terriers exhibited the highest relative risks (3.2 and 1.6, p < 0.05, respectively) when compared to cross breed dogs. The municipalities' ASIR of the two species exhibited a high correlation (R = 0.85, p < 0.01) and the spatial cluster analysis revealed similar geographic hotspots. Also, higher ASIR values both in women and dogs were more frequently found in urbanized areas compared to rural areas. This research sheds light on the shared features and geographical correlation between HBC and canine MGT, highlighting the potential of cross-species environmental oncology studies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Prostate cancer is a common oncological disease of old age with the highest rates of incidence among males older than 65 years old. Diagnosis and treatment may be associated with the onset of adjustment, depressive, and anxiety disorders. The comorbidity with depression and anxiety may lead to a higher risk of suicide, and mortality as well as lower adherence to medical treatments and adverse functional outcomes in patients affected by urologic cancers. The role of genetic vulnerability and pre-morbid personality in predicting the development of mental disorders during cancer disease is debated. For instance, some genetic polymorphisms of the serotonin transporter-related promoter region (5-HTTLPR polymorphism) are associated with higher vulnerability for mental disorders as well as personality traits of neuroticism; both factors are potentially useful for identifying risk of depressive and anxious symptoms among cancer patients. This communication proposes the development of individualized psychobiological approaches to identify possible 'psychobiological' markers associated with the risk of mental disorders in prostate cancer patients., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Industrial Psychiatry Journal.)

Objectives: To develop a new Body Mass Index (BMI) reference (MULT) based on longitudinal data of multi-ethnic populations and to compare it to international BMI references., Methods: The MULT BMI reference was constructed through the LMS method and the Generalized Additive Models for Location Scale and Shape (GAMLSS), with 81 310 observations of 17 505 subjects aged 0-22 years old, from the United Kingdom, Ethiopia, Peru, India, Vietnam, Brazil, and Portugal. Outlier values were removed based on weight z-scores (population level) and based on BMI z-scores using the linear mixed effects model (individual level). The MULT M, S and L curves were compared to the ones of the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF), and Dutch Growth Study (DUTCH). The MULT BMI percentile cutoffs for overweight and obesity were calculated using the adult BMI values of 25 and 30 kg/m 2 at 17, 18, 19, and 20 years old., Results: MULT presented the lowest mean BMI values for the ages 102-240 months for boys and 114-220 months for girls. MULT S values were similar to the WHO and IOTF for children under 60 months of age and the highest during puberty, while the L curve showed to be more symmetric than the other BMI references., Conclusion: The MULT BMI reference was constructed based on recent data of populations from 10 countries, being a good option to assess the nutritional status of multi-ethnic populations., (© 2023 Wiley Periodicals LLC.)

Bisphenol A (BPA) is an endocrine disruptor used in food contact materials, by the application of polycarbonate plastics and epoxy resins. The main objective of this study is to compare the estimate of daily BPA exposure at 13 years of age and in the adult Portuguese population, using different methodological approaches, and assess the associations between this exposure and sociodemographic characteristics., Methodology: Cross-sectional data of 13-years follow-up from a population-based birth cohort Generation XXI (GXXI) (n = 2804) and from the National Food, Nutrition and Physical Activity Survey (IAN-AF 2015-2016) (n = 3845, ≥18 years old) was used. Dietary information was collected through three food diaries for adolescents and two non-consecutive 24-hour-recalls for adults. To estimate the daily exposure to BPA, three methodological approaches were used. "Food groups attribution" merged the food consumption data with the concentration of BPA in food groups. "Regression tree model" and "random forest" combined food consumption information with urinary BPA, measured in a subsample of 24-hour urine (in adolescents n = 216, and in adults n = 82), both used to predict BPA exposure in the remaining sample. The fit-index of the methodologies was assessed through the root mean square error (RMSE), mean absolute error (MAE) and Spearman correlation coefficient (ρ). Associations between BPA exposure and sociodemographic variables were tested by linear regression models, adjusted for sex, age groups (in adults) and educational level. Tolerable Daily Intake (TDI) of 0.2 ng/kg body weight (bw), recently proposed by the European Food Safety Authority (EFSA), was used for the risk characterization of BPA exposure., Results: The "random forest" was found as the best methodology to estimate the daily BPA exposure (adolescents: RMSE = 0.989, MAE = 0.727, ρ = 0.168; adults: RMSE = 0.193, MAE = 0.147, ρ = 0.250). The median dietary BPA exposure, calculated by "food groups attribution", was 79.1 and 46.1 ng/kg bw/day for adolescents and adults, respectively, while "random forest" estimated a BPA exposure of 26.7 and 38.0 ng/kg bw/day. 99.9% of the Portuguese population presented a daily exposure above TDI. Male adolescents, females and higher educated adults, were those more exposed to BPA., Conclusions: The estimated daily BPA exposure strongly depends on the methodological approach. Food groups attribution may overestimate the exposure while the random forest appears to be a better methodological approach to estimate BPA exposure. Nevertheless, for all methods, the Portuguese population presented an unsafe BPA exposure by largely exceeding the safe levels proposed by EFSA., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Since the beginning of the pandemic, there has been a great deal of controversy regarding the role of schools in the spread of SARS-CoV-2 infection, and the relative contribution of students, teachers, and others. To quantify the clustering effect of SARS-CoV-2 infection within classes and schools considering the seroprevalence of specific antibodies among students and school staff (teachers and non-teachers) evaluated in schools located in the Northern region of Portugal. 1517 individuals (1307 students and 210 school staff) from 4 public and 2 private schools, comprising daycare to secondary levels, were evaluated. A rapid point-of-care test for SARS-CoV-2 specific IgM and IgG antibodies was performed and a questionnaire was completed providing sociodemographic and clinical information. We calculated the seroprevalence of IgM and IgG antibodies and estimated the Median Odds Ratio (OR) and 95% confidence interval (CI) to assess the clustering effect, using a multilevel (school and class) logistic regression. SARS-CoV-2 seroprevalence (IgM or IgG) was 21.8% and 23.8% (p = 0.575) in students and school staff, respectively. A total of 84 (8.6%) students and 35 (16.7%) school staff reported a previous molecular diagnosis. Among students, those who reported high-risk contacts only at school (OR = 1.13; 95% CI 0.72-1.78) had a seroprevalence similar to those without high-risk contacts; however, seroprevalence was significantly higher among those who only reported a high-risk contact outside the school (OR = 6.56; 95% CI 3.68-11.72), or in both places (OR = 7.83; 95% CI 5.14-11.93). Similar associations were found for school staff. The median OR was 1.00 (95% CI 1.00, 1.38) at the school-level and 1.78 (95% CI 1.40, 2.06) at the class-level. SARS-CoV-2 seroprevalence was similar between students and staff, without a clustering effect observed at the school level, and only a moderate clustering effect documented within classes. These results indicate that the mitigation measures in the school environment can prevent the spread of class outbreaks to the remaining school community., (© 2023. The Author(s).)

(1) Background: Family psychoeducation is a well-recognized intervention which aims to improve the outcomes of illness in patients affected by psychosis. It has benefits in treatment adherence and leads to a reduction in relapses, higher levels of patient insight, and lower levels of stress within the family and among caregivers. (2) Methods: Eight patients and their families were recruited and randomly assigned to a Falloon-based family psychoeducation (FPP) intervention, and nine patients and their families were randomized to a Gestalt-based family intervention (GT). We compared the outcomes of these two treatment groups at a baseline assessment (T0), at the end of the programs (T1), and 6 and 12 months after the end of the programs (T2 and T3). The assessments included examinations of cognition (The Mini-Mental State Examination (MMSE) and The Five Point Test (5 Point)), the psychopathology and severity of illness (The Brief Psychiatric Rating Scale (BPRS), The Positive and Negative Syndrome Scale (PANSS), and The Clinical Global Impression Scale (CGI)), expressed emotion in families (Expressed Emotionality (Family Questionnaire-EE)), patient quality of life (The World Health Organization Quality of Life-BREF (WHOQOL-B)), social functioning (The Personal Social Performance (SPS)), aggression (Modified Overt Aggression Scale (MOAS)), and treatment adherence (The Brief Medication Adherence Report Scale (BMARS)). The primary aim was to test whether the FFP vs. GT program was more effective in improving treatment adherence over time. (3) Results: treatment adherence improved much more in the FFP group over time at any follow-up: +43.1% at T1, +24.0% at T2, and +41.6% at T3. Other characteristics, including psychopathology and the clinical stability of the subject, did not change over time. (4) Discussion: Family psychoeducation based on the Falloon program was effective at improving treatment adherence and contributed to avoiding relapses in the long term. Further studies on larger samples should be conducted to confirm this evidence, and similar psychoeducational programs should be routinely promoted in the clinical setting.

Background: Few studies examine the relationship between socioeconomic factors and trends in mortality in high-income European countries. Due to the lack of regional-level data, most recent studies on social inequality in Portugal do not investigate regional differences. This study analyses time trends and regional disparities in the evolution of perinatal mortality (PMR) and infant mortality (IMR) associated with demographic and socioeconomic indicators following Portugal's 2008 economic and financial crisis., Methods: Associations were assessed using generalised linear models. A Poisson joinpoint regression model was applied to identify relevant PMR and IMR changes between 2000 and 2018. Country regional disparities were analysed using Mixed Effect Multilevel models., Findings: IMR and PMR significantly decreased in the pre-crisis period but not in the post-crisis period. The significant differences between regions in IMR and PMR in 2000 were followed by a different evolution of regional IMR after 2008. PMR and IMR were not significantly associated with socioeconomic indicators. A significant positive association with maternal age at first birth was identified., Interpretation: Results confirm the influence of the crisis on PMR and IMR trends in Portugal, taking into account recurring associations between macroeconomic cycles, variations in mortality trends, macroeconomic volatility, and stagnation of IMR and PMR. Regional inequalities confirm the internal variability of the crisis influence and persistent spatial inequalities affecting IMR patterns., Funding: FCT, under the Institute of Public Health of the University of Porto (ISPUP)-EPIUnit (UIDB/04750/2020) and ITR (LA/P/0064/2020), Maastricht University's external PhD programme under the Care and Public Health Research Institute (CAPHRI), and the RECAP preterm project (grant agreement no 733280)., Competing Interests: All authors declare that they have answered every question and have not altered the wording of any of the questions on the “ICMJE COI Form”., (© 2023 The Author(s).)

Background: Solid Organ Transplant recipients (SOTR) appear to be at particular high risk for critical COVID-19 due to immunosuppressive drugs and comorbidities. We report the first description of clinical course and short-term outcomes of kidney and liver transplant recipients with confirmed COVID-19 in Mexico. The objective of this paper was evaluate the clinical course of transplant patients with COVID-19 infection., Material and Methods: We retrospectively evaluated SOTR (kidney and liver) over 18 years of age with confirmed diagnosis of COVID-19 from tertiary care centers in Mexico., Results: Data from 45 kidney transplant recipients were recorded. Median (IQR) age was 43 (IQR 25-70) years. Admission to hospital was required in 37 (75.5 %) patients, of which 8 (16.3%) were hospitalized at Intensive Care Unit (ICU). Acute kidney injury (AKI) stage was documented in 33 (67%) patients. The time of hospitalization was 8 (IQR 6-12) days. Six patients died (12.2%). Additionally, data from 10 liver transplant recipients were included. During their evolution, 5 / 10 required hospital admission and there were no deaths in this group., Conclusions: Transplant recipients show a higher fatality rate and complications from SARS-CoV-2 infection; more studies are needed to identify prognostic factors and effective anti-SARS-CoV-2 therapies.

Introduction: Psoriasis is a common, chronic, and inflammatory skin disorder with a high personal, social and economic burden and important implications for healthcare systems. The aim of this study was to provide an epidemiological characterization of individuals with psoriasis in Portugal., Material and Methods: A large observational, cross-sectional, nationwide, population-based survey study developed by the Portuguese Psoriasis Group of the Portuguese Society of Dermatology and Venereology (GPP-SPDV). A structured questionnaire was designed and applied by experienced interviewers to a random, representative sample of Portuguese individuals with psoriasis and/or psoriatic arthritis. Patients were considered to have psoriasis if they replied positively to one of the following questions: "Does any physician have ever diagnosed you with psoriasis?" or "Do you have a skin disorder characterized by scaling, reddish skin lesions located in the elbows/knees/scalp?"., Results: A total of 6381 individuals were interviewed, of which 283 met the criteria for psoriasis, corresponding to a prevalence rate of 4.4% (95% CI 3.95 - 4.98). Out of the participants that met psoriasis criteria, 24% had suggestive signs/symptoms but did not have a clinical diagnosis established and were not being monitored by a physician. Although more than 70% of participants had active disease (scaling, erythema, or pruritus) and one third had joint symptoms, only 12% were on systemic treatment. Fifty percent of participants with psoriasis (n = 139) had relevant comorbidities (most frequently depression/anxiety and cardiometabolic diseases). Sixteen percent of participants with psoriasis (n = 46) reported that psoriasis interfered with their daily activities (median impact of 5 in a 0 - 10 scale) and 12% mentioned the disease had an impact in their sexual life (median impact of 5 in a 0 - 10 scale)., Conclusion: The results of this study suggest that the prevalence rate of psoriasis is likely to be high in Portugal, and several gaps exist at different levels of healthcare delivery to these patients, from diagnosis to treatment. This study provides important data for the future planning of interventions targeting the improvement of psoriasis care in Portugal.

Vaccination for influenza has been essential over the years to protect the most vulnerable populations. Moreover, it was recently suggested that influenza vaccination might confer some nonspecific immunity to other viruses and be associated with a lower risk for coronavirus disease 2019 (COVID-19) morbidity and mortality. Therefore, we aimed to assess the effectiveness of repetitive influenza vaccination against SARS-CoV-2 infection in a cohort of health care workers (HCWs). This study was conducted among HCWs at São João University Hospital Center (CHUSJ), Porto, Portugal, a tertiary reference hospital for diagnosis and therapy, one of the largest hospitals in the country with approximately 6000 HCWs. We analyzed databases for influenza vaccination conducted between 2012 and 2019 and COVID-19 laboratory testing retrieved from the first and last registered positive COVID test date before HCW's COVID-19 vaccination started. The study outcome was the incidence of the first SARS-CoV-2 infection, as determined by reverse transcription polymerase chain reaction (RT-PCR). Age and sex were considered potential confounders. We used multivariable Cox regression to estimate odds ratios. Neither the absolute number nor the proportion of influenza shots influenced the risk of getting infected by SARS-CoV-2 (adjusted odds ratio 1.02, 95% CI: 0.9-1.06 and 1.17 95% CI: 0.86-1.58, respectively). Similar findings were observed in most cases when the analysis was restricted by year. The findings from our retrospective observational analysis of a HCWs cohort failed to support any protective effect between repetitive influenza vaccination and SARS-CoV-2 infection., Competing Interests: None., (Copyright © 2023 The Authors.

Background: Body Mass Index (BMI) is an informative factor on body fatness which has been associated to higher levels of Perinatal Depression (PD) and complications during pregnancy. We aimed to explore the impact of pre-pregnancy and postnatal BMI on the risk of Perinatal Depression and pregnancy outcomes among women recruited at their third trimester of pregnancy., Methods: We report on findings from a large multi-centre study conducted in the South of Italy and involving 1611 women accessing three urban gynaecological departments from July to November 2020. Pregnant women were assessed at their third trimester of pregnancy (T0) and after the childbirth (T1) ;The Edinburgh Postnatal Depression Scale (EPDS) has been employed for the screening of PD over time (T0 and T1) as well as other standardized measures for neuroticism, resilience, and quality of life at baseline. BMI (T0 and T1) and other socio-demographic and clinical characteristics have been collected., Results: Over-weight and obesity (higher levels of BMI) were associated with higher risk of PD (higher scores of EPDS), higher neuroticism and poorer subjective psychological well-being among enrolled women. Also, obesity and over-weight were associated with lower education, higher number of physical comorbidities, medical treatments and complications during pregnancy., Conclusions: Over-weight and obesity may impact on mental health and pregnancy outcome of women enrolled. Psycho-educational interventions aimed to improve the management of physical and emotional issues may reduce the risk of PD and complications during pregnancy.

Introduction: It is estimated that approximately 70% of patients with rectal cancer who undergo surgery will suffer from Low Anterior Resection Syndrome (LARS). In the last decades, sacral neuromodulation (SNM) has been widely used in urinary dysfunction and in faecal incontinence refractory to medical treatment. Its application in LARS has been investigated and has shown promising results. The paper's aim is to present a systematic review and meta-analysis of the available literature and evaluate the therapeutic success of SNM in patients with LARS., Methods: A systematic search was performed in international health-related databases: Cochrane Library, EMBASE, PubMed and SciELO. No restrictions on year of publication or language were applied. Retrieved articles were screened and selected according to set inclusion criteria. Data items were collected and processed for each included article and a meta-analysis was done according to the PRISMA guidelines. The primary outcome was the number of successful definitive SNM implants. Further outcomes included changes in bowel habits, incontinence scores, quality of life scores, anorectal manometry data and complications., Results: A total of 18 studies were included, with 164 patients being submitted to percutaneous nerve evaluation (PNE) with 91% responding successfully. During follow-up of therapeutic SNM some devices were explanted. The final clinical success rate was 77% after permanent implant. Other outcomes, such as the frequency of incontinent episodes, faecal incontinence scores, quality of life scores were overall improved after SNM. The meta-analysis showed a decrease in 10.11 incontinent episodes/week; a decrease of 9.86 points in the Wexner score and an increase in quality of life of 1.56 (pooled estimate). Changes in anorectal manometry were inconsistent. Local infection was the most common post-operative complication, followed by pain, mechanical issues, loss of efficacy and haematoma., Discussion/conclusion: This is the largest systematic review and meta-analysis concerning the use of SNM in LARS patients. The findings support the available evidence that sacral neuromodulation can be effective in the treatment of LARS, with significant improvement in total incontinent episodes and patients´ quality of life., (© 2023.

Peripartum depression (PPD) is a major complication of pregnancy, and numerous risk factors have been associated with its onset, including dysfunctional coping strategies and insecure attachment styles, both during pregnancy and postpartum. The aim of our study was to investigate the role of coping strategies in mediating the relationship between women's attachment style and depressive symptomatology in pregnancy and one week after giving birth in a large sample of women (N = 1664). Our hypothesis was that the relationship between anxious and avoidant attachment and depressive symptomatology would be mediated by use of maladaptive coping strategies. The assessment instruments were Edinburgh Postnatal Depression Scale (EPDS), Brief Coping Orientation for Problem Experiences (COPE), and Experiences in Close Relationship Scale (ECR). The results indicated that the effect of insecure attachment styles (anxious and avoidant attachment) on antepartum depressive symptomatology was partially mediated by dysfunctional coping styles. Anxious attachment also has an indirect significant effect on postpartum depressive symptomatology through emotional coping; however, avoidant attachment does not seem to be significantly related to postpartum depressive symptoms. Our findings revealed that not only is it important to consider attachment in understanding peripartum depressive symptomatology, but also that coping plays an important role in these relationships. These findings would help a preventive coping-based intervention strategy to enhance the capacity of women with insecure attachment styles to use more adaptive coping during and after pregnancy.

Background: The characteristics of allergic sensitization profiles can differ between populations and geographic regions, contributing differently to the association with allergic diseases. Consequently, the sensitization trajectories found in previous studies conducted in Northern Europe may not apply in Southern European countries., Objective: To identify trajectories of allergic sensitization profiles during childhood and evaluate the association with allergic outcomes, using data from a Portuguese birth cohort., Methods: A random sample from Generation XXI was screened for allergic sensitization at 10 years of age. Among 452 allergic sensitized children, 186 were tested with ImmunoCAP ™ ISAC multiplex array that detects 112 molecular components, at three follow-ups (4, 7, and 10 years old). Information on allergic outcomes (asthma, rhinitis, atopic dermatitis) was obtained at the 13-year-old follow-up. Latent class analysis (LCA) was used to identify clusters of participants with similar sensitization profiles. Then, sensitization trajectories were defined based on the most prevalent transitions between clusters over time. Logistic regression was applied to estimate the association between sensitization trajectories and allergic diseases., Results: Five trajectories were proposed: "no/few sensitizations," "early persistent house dust mites (HDM)," "early HDM and persistent/late grass pollen," "late grass pollen," and "late HDM." The "early HDM and persistent/late grass pollen" trajectory was associated with rhinitis and "early persistent HDM" with asthma and rhinitis., Conclusion: Distinct sensitization trajectories pose different risks in the development of allergic diseases. These trajectories present some differences from those in Northern European countries and are important for planning adequate prevention health plans., (© 2023 European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

This longitudinal population-based birth cohort study aims to identify childhood adversity patterns over the first 13 years of life and to examine its association with health-related behaviours and outcomes in early adolescence. Using data from the Portuguese birth cohort Generation XXI, we performed latent class analysis to explore the underlying patterns of adversity from birth to early adolescence, using 13 adversity items assessed in five time points. Health-related behaviours and outcomes were evaluated at 13 years. Adjusting for parental unemployment, logistic regression models were performed to determine the association between adversity patterns and outcomes. Among 8647 participants, three adversity patterns were identified: "low adversity" (56.1%), "household dysfunction" (17.2%) and "multiple adversities" (26.7%). For the "household dysfunction" pattern, girls and boys showed associations with increased odds of alcohol/tobacco use (adjusted odds ratio [AOR]: 1.78; 95% confidence interval [CI]: 1.32-2.40; AOR:1.84; CI:1.38-2.46, respectively) and depressive symptoms (AOR:2.34; CI:1.58-3.48; AOR:5.45; CI:2.86-10.38, respectively). Boys also presented low consumption of fruits/vegetables (AOR:1.51; CI:1.04-2.19). For the "multiple adversities" pattern, both girls and boys showed an increased probability of alcohol/tobacco use (AOR:1.82; CI:1.42-2.33; AOR:1.63; CI:1.30-2.05, respectively) and depressive symptoms (AOR:3.41; CI:2.46-4.72; AOR:5.21; CI:2.91-9.32, respectively). Boys also revealed increased odds of low consumption of fruits/vegetables (AOR:1.67; CI:1.24-2.23). Childhood adversity patterns are associated with unhealthy behaviours and depressive symptoms in early adolescence. Public policies and early interventions targeting vulnerable children, families and communities can potentially reduce the detrimental effects of adversities on health and promote individual and community resilience., Competing Interests: Declaration of Competing Interest None to declare., (Copyright © 2023 The Authors.

Evidence on the association between children's food insecurity (FI) and dietary patterns (DPs) is scarce. This study assessed the association between children's FI and a priori and a posteriori -defined DPs in a Portuguese population-based sample of children. A cross-sectional study including 2800 children from the 10-year-old follow-up of the Generation XXI birth cohort was performed. Data on food security status, assessed by the Self-administered Food Security Survey Module for children (SAFSSMC), dietary intake and socio-demographics were collected. A previously developed Healthy Eating Index (HEI) was adapted for this study. Using the HEI score and its food groups, linear and logistic regression models were performed. Using latent class analysis, five a posteriori -defined DPs were identified. The DPs names considered an overall picture of the DP. Food security status as a categorical (food security/FI) and continuous variable (SAFSSMC raw score: higher scores representing higher FI) was used. Multinomial logistic regression models were used to assess the association between food security status and DPs. Children's FI (9·4 %) was inversely associated with the HEI score ( β =-0·695;95%CI:-1·154,-0·235), representing worse diet quality. A higher SAFSSMC raw score was associated with low fruit and vegetables (OR=1·089;95%CI:1·023,1·159) and seafood and eggs consumption (OR=1·073;95%CI:1·009,1·142) and high consumption of meat and meat products (OR=1·091;95%CI:1·026,1·160), salty snacks (OR=1·067;95%CI:1·003,1·136) and soft drinks (OR=1·097;95%CI:1·031,1·168). The SAFSSMC raw score was positively associated with 'Low consumption' (OR=1·119;95%CI:1·016,1·232), 'Energy-dense foods' (OR=1·155;95%CI:1·028,1·298) and 'Snacking' (OR=1·119;95%CI:1·006,1·245) DPs. FI was associated with worse dietary choices. Intervention strategies targeting food insecure children should be developed to promote healthy dietary habits.

Objectives: Premature adrenarche is often linked to a cluster of endocrine-metabolic risk factors. Our objective was to explore the association of dehydroepiandrosterone sulfate (DHEAS) levels at age 7 with cardio-metabolic traits at ages 10 and 13, independently of adiposity and pubertal stage., Methods: Longitudinal study of 603 individuals (301 girls/302 boys) from the Generation XXI birth cohort. DHEAS at age 7 was measured by immunoassay. Anthropometrics, pubertal staging, blood pressure, and metabolic outcomes were evaluated at ages 7, 10, and 13. Pearson correlations between DHEAS and cardio-metabolic traits (insulin, HOMA-IR, triglycerides, LDL-cholesterol, high-sensitivity C-reactive protein, and systolic and diastolic blood pressure) were computed. Path analysis was used to estimate the effect of DHEAS at age 7 on cardiometabolic traits at ages 10 and 13, adjusted for body mass index (BMI) z-score and Tanner stage., Results: DHEAS at age 7 correlated positively with insulin and HOMA-IR at ages 7 and 10 in both sexes, and at age 13 in girls, but not in boys. In girls, DHEAS levels at age 7 directly influenced HOMA-IR at age 13, controlling for BMI and Tanner stage. In boys, DHEAS at age 7 did not influence HOMA-IR at ages 10 and 13. DHEAS at age 7 did not influence the other cardio-metabolic outcomes analyzed., Conclusions: DHEAS levels in mid-childhood have a positive longitudinal association with on insulin-resistance that persists, in girls, but not in boys, at least until age 13. No association was found regarding dyslipidemia, hypertension, or low-grade inflammation., (© 2023 Walter de Gruyter GmbH, Berlin/Boston.)

Introduction: The study of crisis events provides important lessons to prepare for upcoming events. The Great Recession's impact on perinatal health in Europe can provide relevant insights into the healthcare and social protection systems' response to the protection of the health of the most vulnerable groups., Objective: To assess time trends and international disparities in perinatal mortality rates (PMR) and infant mortality rates (IMR), following the Great Recession, and their association with socioeconomic indicators in Portugal, Greece, Italy and Spain., Methods: Associations were assessed through generalised linear models for all four countries. A Poisson joinpoint regression model was applied to explore PMR and IMR trend changes between 2000 and 2018. Country disparities were analysed using mixed-effects multilevel models., Results: IMR and PMR have decreased overall in the four selected countries between 2000 and 2018. Still, whereas in Spain, Italy and Portugal the decreasing pace was attenuated after 2009, in Greece a positive trend was found after the 2008 crisis. IMR and PMR were significantly associated with socioeconomic indicators in all four countries. National disparities in the evolution of IMR and PMR were significantly associated with most socioeconomic indicators between 2000 and 2018., Conclusion: Our results confirm the impact of the Great Recession on PMR and IMR trends in all four countries, taking recurring associations between macroeconomic cycles, variations in mortality trends, macroeconomic volatility and stagnation of IMR and PMR into account. The association with socioeconomic indicators stresses the need to strengthen social protection and healthcare systems to better protect the population's health from the earliest days., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

This study aimed to explore the factors associated with the consumption of meat vs. meatless meals and to assess the applicability of a multi-state model to describe transitions between lunch and dinner. Fifteen thousand four hundred and eight main meals (lunch and dinner) from a sample of adults (18-84 years, n  = 3852) from the Portuguese Food, Nutrition and Physical Activity Survey (IAN-AF 2015-2016) were categorised as meat, fish, ovolactovegetarian or snack. Adjusted generalised-mixed-effects models were used to explore the associations and a time-homogeneous Markov-multi-state model was applied to study the transitions. Women, older and higher educated individuals presented higher odds of consuming meatless meals and lower hazard of transitioning to meat in the following main meal. Strategies for replacing meat with more sustainable foods should be specific towards different population groups. Studying transitions across main meals, using multi-state models, can support the development of feasible, realistic and group-specific strategies to replace meat and promote dietary variety.

Objective: To describe sleep-wake patterns in young children, based on sleep characteristics in early infancy and preschool ages, identifying their main sociodemographic characteristics, and to assess the association between different sleep characteristics at both ages., Method: We included 1092 children from the Generation XXI birth cohort, evaluated at six months and four years of age, by face-to-face interviews. Sleep patterns were constructed through latent class analysis and structured equation modeling, including data on wake-up time and bedtime, afternoon naps, locale of nighttime sleep and night awakenings. To estimate the association between sociodemographic characteristics and sleep patterns, odds ratios and 95% confidence intervals were computed using logistic regression., Results: Two sleep patterns were identified through latent class analysis: pattern 1 was characterized by earlier bedtime and wake-up times, while pattern 2 was defined by later times. When compared with pattern 1, pattern 2 was more frequent among children whose mothers had changed from partnered to not partnered until preschool age and those who did not stay at the kindergarten, and was less common among those with siblings. Through structured equation modeling, an aggregating factor was identified at preschool age, which was mainly correlated with bedtime and wake-up time. A positive association between sleep characteristics evaluated in early infancy and in preschool ages was observed., Conclusions: Sleep patterns and circadian sleep preferences seem to be developed early in life, which highlight the importance of promoting an adequate sleep hygiene from infancy, assuming its impact on sleep quality during the life course., (Copyright © 2023.

Pregnancy frequently is associated with emotional conditions such as anxiety and depression. Perinatal depression has an incidence of around 12%. Only recently researcher put the attention on the effects of pre- and postpartum psychopathology on infant neurocognitive development. Neurobiology studies indicate that perinatal maternal depression can significantly affect the structure and function of children's prefrontal cortex and modulate the development of cognitive abilities from intrauterine life. On the topic, the scientific literature appears ambiguous, reporting mixed results. Some studies have found no significant differences in developmental outcomes between prenatal and postpartum exposure to maternal depression, others have suggested a greater burden of depression in pregnancy than in postpartum, and still others have emphasized the role of chronicity of symptoms rather than the period of onset. Few studies have examined the effects of different developmental trajectories of maternal depression on children's neurocognitive outcomes. The assessment of maternal health has for years been limited to postpartum depression often neglecting the timing of onset, the intensity of symptoms and their chronicity. These aspects have received less attention than they deserve, especially in relation to the effects on children's neurocognitive development. The aim of this Perspective was to highlight inconsistencies and gaps that need to be filled in the approach to the study of this problem. Given the wide heterogeneity of data in the current literature, further studies are needed to clarify these interactions. This Perspective provides an overview of current progress, future directions, and a presentation of the authors' views on the topic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Severo, Ventriglio, Bellomo, Iuso and Petito.)

Purpose: To determine the stability of appetitive traits during infancy and their association with early life exposures., Methods: Participants were from the BiTwin birth cohort (longitudinal study of Portuguese infants). Appetitive traits at 3 months were measured using the Baby Eating Behaviour Questionnaire (n = 347) and at 12 months with the Children's Eating Behaviour Questionnaire for toddlers (n = 325). Stability was assessed with multi-level models. The association of early life exposures (weight for gestational age, mode of feeding, prematurity, smoking during pregnancy, maternal pre-pregnancy BMI, gestational weight gain, and diabetes mellitus diagnosis) with infant appetitive traits was estimated by multivariable linear regression models., Results: Appetite traits showed limited stability (ICCs: 0.25-0.34). Associations with early life exposures varied by age. At 3 months, infants of mothers with higher pre-pregnancy BMI and excessive gestational weight gain had low Satiety Responsiveness. In contrast, infants small for gestational age scored high in this trait (β̂ = 0.241; 95% CI 0.056-0.425). Exclusively formula-fed infants presented weak food approach traits at this age, namely low Enjoyment of Food (β̂ = - 0.145; 95% CI - 0.270 to - 0.019) and Food Responsiveness (β̂ = - 0.415; 95% CI - 0.618 to - 0.212). At 12 months, infants who were small for gestational age had low Food Responsiveness (β̂ = - 0.297; 95% CI - 0.523 to - 0.072), in contrast, infants of mothers who gained excessive gestational weight had high scores in this trait. Formula feeding was related to rapid eating (Slowness in Eating: β̂ = - 0.252; 95% CI 0.451 to - 0.054)., Conclusion: Early life exposures may play a role in the development of infants' appetitive traits, which then change during the first year of life. Interventions focussed on maternal and infant health may have the potential to shape appetite in infancy., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.)

Adequate nutritional intake in the first years of life is crucial for future health. The purpose of this study is to assess the adequacy of nutritional intake in Portuguese toddlers. The EPACI Portugal 2012 is a cross-sectional study of a representative sample of toddlers (n = 2230), aged between 12 and 36 months. Data on diets were collected by trained interviewers. The current analysis included 853 children with full data from 3-day food diaries completed by parents/caregivers. Intakes of energy, macro- and micronutrients were estimated through Statistical Program to Assess Dietary Exposure (SPADE). Nutritional adequacy was evaluated using Dietary Reference Values established by the European Food Safety Authority. A large proportion of children exceeded the recommended energy intake. The median daily protein intake was 4.7 g/kg/day, five times more than that recommended. About 9% and 90% of the children consumed a lower proportion of energy than the lower limit of the Reference Intake range for carbohydrates and fat, respectively. Around a third consumed less fibre and magnesium and 100% less vitamin D than the recommended Adequate Intake (AI). Almost a third consumed less vitamin A than the recommended Average Requirement (AR) and 86% of the children showed excessive sodium consumption. Portuguese toddlers consumed a low proportion of energy from fat, had energy and protein intakes above the recommendations and excessive intakes of sodium, and inadequate intakes of vitamin A. Every child consumed less than the recommended AI for vitamin D., (© 2023 The Authors. Nutrition Bulletin published by John Wiley & Sons Ltd on behalf of British Nutrition Foundation.)

Background: Despite the potentially significant impact of women-prenatal care provider communication quality (WPCQ) on women's perinatal health, evidence on the determinants of those perceptions is still lacking, particularly among migrant women., Methods: We aimed to examine the effect of women's host-country language proficiency on their perceived WPCQ. We analyzed the data of 1210 migrant and 1400 native women who gave birth at Portuguese public hospitals between 2017 and 2019 and participated in the baMBINO cohort study. Migrants' language proficiency was self-rated. Perceived WPCQ was measured as a composite score of 9 different aspects of self-reported communication quality and ranged from 0 (optimal) to 27., Results: A high percentage of women (29%) rated communication quality as "optimal". Zero-inflated regression models were fitted to estimate the association between language proficiency and perceived WPCQ. Women with full (aIRR 1.35; 95% CI 1.22,1.50), intermediate (aIRR 1.41; 95% CI 1.23,1.61), and limited (aIRR 1.72; 95% CI 1.45,2.05) language proficiencies were increasingly more likely to have lower WPCQ when compared to natives., Conclusions: Facilitating communication with migrant women experiencing language barriers in prenatal care could provide an important contribution to improving prenatal care quality and addressing potential subsequent disparities in perinatal health outcomes., (© 2023.

Background: There are no data on lung function reference values for Portuguese children, and the contribution from the Portuguese data set in the Global Lung Function Initiative (GLI) is scant., Objectives: We aimed to estimate new up-to-date reference values for Portuguese children by fitting a multivariable regression model to a general population sample. Further, we intended to assess the external validity of the obtained reference values and to compare them to the GLI reference values., Methods: A random sample of 858 children from 20 primary schools were screened by health questionnaire, physical examination, and spirometry. Spirometric parameters recorded were FVC, FEV 1 , and FEF 25-75 . Multiple regression models were used to derive reference equations., Results: Overall, 481 children, aged between 7 and 12 years, 267 boys (55.5%), were included. Boys had higher values for FVC and FEV 1 than girls ( P  < .05). The strongest correlation was found for FVC with height ( r  = 0.71 for boys and 0.70 for girls), while the lowest correlation was observed in both sexes for FEF 25-75 with age ( r  = 0.23). Height was the most significant predictor of FVC, FEV 1 , and FEF 25-75 in our models. Weight and body mass index were not significant predictors for boys but had a significant effect on girls' equations for all spirometry parameters. Compared to obtained reference equations with GLI, they performed better for FVC in boys, FEV 1 in girls, and FEF 25-75 in both boys and girls., Conclusion: We offer up-to-date reference values of spirometry for Portuguese children that can be used in clinical practice and research., (© 2023 The Author(s).)

Studies based on twins are ideal to disentangle the relative contribution of different factors in the development of eating behaviors. This study aims to evaluate if changes in problematic eating behaviors from 4 to 7 years old are more influenced by the genetics, the shared environment of twins, or by individual characteristics of each twin. A total of 86 caregivers (mostly mothers) of twins from the Generation XXI birth cohort provided information on eating behaviors at 4 and 7 years of age. A score of problematic eating behaviors was developed. The Common fate model and the ACE model were used to estimate the effect of shared, individual, and genetic characteristics on changes in eating behaviors. At the dyadic level (shared), the eating behavior score at 4 years old was significantly and positively associated with the eating behavior at 7 years of age (β = 0.402, 95% CI 0.063;0.657). At the individual level, no significant association was observed (β = 0.020, 95% CI -0.078;0.125). The ACE model also showed the shared environment as the major responsible for the changes in eating behaviors from 4 to 7 years old. It also showed that genetic characteristics decreased their relevance overtime. This study supports that changes in eating behaviors from 4 to 7 years of age are mostly associated with the shared environment rather than individual characteristics of each twin. These results are important to improve future strategies to promote healthy environments., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

Objective: We aimed to explore the association between dehydroepiandrosterone sulphate (DHEAS) levels at age 7, pubertal development between ages 10 and 13, and age at menarche., Design and Participants: This is a longitudinal study of 603 individuals (301 girls, 302 boys) from the Generation XXI cohort., Measurements: Evaluation of the participants at ages 7, 10 and 13 included anthropometry and Tanner staging. Pubertal development between ages 10 and 13 was categorized using latent class analysis, based on Tanner stages. The association between DHEAS at age 7 and pubertal development between ages 10 and 13 was conducted with binomial logistic regression, adjusted for BMI z-score. The variation of age at menarche in relation to DHEAS levels at age 7, controlling for maternal age at menarche, birth weight z-score and BMI z-score, was estimated fitting a linear regression model., Results: Pubertal development at ages 10-13 was categorized into two classes-Class 1 had a higher probability for the lower Tanner stage (less advanced sexual maturation) and Class 2 had a higher probability for the higher Tanner stage (more advanced sexual maturation). In girls, taking Class 1 as a reference, Class 2 was positively associated with BMI z-score and DHEAS. In boys, Class 2 was positively associated with BMI, but not with DHEAS. DHEAS levels at age 7 were negatively associated with age at menarche, after adjustment for maternal age at menarche, birth weight and BMI., Conclusion: In girls, but not in boys, DHEAS at age 7 was positively associated with more advanced pubertal development between ages 10 and 13, and with earlier age at menarche., (© 2022 John Wiley & Sons Ltd.)

Portugal has high fish/seafood consumption, which may have both risks and benefits. This study aims to quantify the net health impact of hypothetical scenarios of fish/seafood consumption in the Portuguese population using a risk-benefit assessment methodology. Consumption data from the National Food, Nutrition and Physical Activity Survey 2015-2016 ( n 5811) were used to estimate the mean exposure to methylmercury and EPA + DHA in the current and the alternative scenarios considered. Alternative scenarios (alt) were modelled using probabilistic approaches to reflect substitutions from the current consumption in the type of fish/seafood (alt1: excluding predatory fishes; alt2: including only methylmercury low-level fishes) or in the frequency of weekly fish/seafood consumption (alt3 to alt6: 1, 3, 5 or 7 times a week, replacing fish/seafood meals with meat or others). The overall health impact of these scenarios was quantified using disability-adjusted life years (DALY). In the Portuguese population, about 11 450 DALY could be prevented each year if the fish/seafood consumption increased to a daily basis. However, such a scenario would result in 1398 extra DALY considering the consumption by pregnant women and the respective risk on fetal neurodevelopment. Our findings support a recommendation to increase fish/seafood consumption up to 7 times/week. However, for pregnant women and children, special considerations must be proposed to avoid potential risks on fetal neurodevelopment due to methylmercury exposure.

Objective: To assess the influence of longitudinal weight gain from 0 to 4 years old on dehydroepiandrosterone sulphate (DHEAS) levels at 7 years old., Design: DHEAS levels were measured at 7 years old in a subsample of 587 children from the Generation XXI birth cohort. Weight trajectories (0-4 years of age) were identified using model-based clustering and categorized as "normal weight gain," "weight gain during infancy," "weight gain during childhood" and "persistent weight gain.", Measurements: Differences in DHEAS levels at age 7 between the four weight trajectories were analysed through analysis of covariance (ANCOVA), adjusted for birth weight (BW) and body mass index (BMI)., Results: In the crude analysis, compared with the "normal weight gain" trajectory (5.53 (95% CI: 5.10-5.98] µmol/L), DHEAS levels were significantly higher in children in the "persistent weight gain" (8.75 [95% CI: 7.23-10.49] µmol/L, p &lt; .001] and in children in the "weight gain during infancy" trajectories (7.68 [95% CI: 6.22-9.49] µmol/L, p = .021] and marginally significantly higher in children in the "weight gain during childhood" trajectory (6.89 (95% CI: 5.98-8.00) µmol/L; p = .052). In BW- and BMI-adjusted model, a statistically significant difference in DHEAS levels was found between the "persistent weight gain" (7.93 [95% CI: 6.43-9.86] µmol/L) and the "normal weight gain" trajectories ([5.75 [95% CI: 5.32-6.23] µmol/L; p = .039)., Conclusion: Higher DHEAS levels are found in 7-year-old children following a trajectory of persistent weight gain from 0 to 4 years, independently of their BW or current BMI, highlighting the impact of exposure to overweight in the first years of life on prepubertal adrenal androgen production., (© 2022 John Wiley & Sons Ltd.)

Objective: We aimed to quantify SARS-CoV-2 specific antibodies' seroprevalence among university students in Porto. Methods: A rapid point of care testing for SARS-CoV-2 specific immunoglobulin (Ig) M and IgG antibodies was performed, and a questionnaire was applied to 6512 voluntary students from September to December 2020. We computed the apparent IgM, IgG, and IgM or IgG prevalence, and the true prevalence and 95% credible intervals (95% CI) using Bayesian inference. Results: We found an apparent prevalence (IgM or IgG) of 9.7%, the true prevalence being 7.9% (95% CI 4.9-11.1). Prevalence was significantly higher among males (10.9% vs. 9.2%), international students (18.1% vs. 10.4% local vs. 8.8% nationally displaced), and increased with age. Those with a known risk contact, that experienced quarantine, had symptoms, or a previous negative molecular test had a higher seroprevalence. Of the 91 (1.4%) students who reported a molecular diagnosis, 86.8% were reactive for IgM or IgG. Conclusion: Based on immunological evidence infection was 5.6-fold the reported molecular diagnosis. The higher seroprevalence among male, older, and international students emphasizes the importance of identifying particular groups., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Meireles, Costa, Novais, Miranda, Lopes, Severo and Barros.)

Background & Aims: Ultra-processed foods (UPF) consumption has increased greatly over the last decades but its impact on health remains unclear. This study aimed to evaluate the prospective effect of different degrees of food processing on children's cardiometabolic profile., Methods: Children from the Portuguese population-based birth cohort Generation XXI evaluated at 7 and 10 years of age (y), with dietary information at 7 y and anthropometric measurements at 10 y, were included in the present study (n = 3034). Dietary data were collected by 3-day food diaries and all reported food items were classified according to the degree of processing using the NOVA classification system. The daily consumption of the NOVA classification groups was calculated (in grams, as a proportion of total grams and total energy intake). The cardiometabolic outcomes included were serum markers [fasting glucose, insulin, blood lipids], anthropometric measurements [body mass index (BMI) and waist circumference (WC)], body composition [fat-free mass (FFM) and fat mass (FM)] and blood pressure (BP). Age- and sex-specific sample z-scores were obtained for all outcomes. Principal Component Analysis was used to identify a potential cluster of cardiovascular risk factors. Generalized linear models were fitted to evaluate the association between the consumption according to the processing degree (as absolute gram intake) and the individual cardiometabolic risk factors and cluster, adjusted for child's sex, maternal age and education and remaining NOVA groups. A mediation role of children's BMI in the previous analysis were tested., Results: At 7 y, the daily median consumption of un/minimally processed, processed and UPF was 1210 g, 113 g and 433 g (68%, 6% and 25% of the total grams, as well as 51%, 15% and 31% of the total energy intake, respectively). After adjustment, an increase of 100 g in the consumption of un/minimally processed at 7 y was associated with a lower BMI (βˆ = -0.028; 95%CI: -0.043; -0.014), WC (βˆ = -0.020; 95%CI: -0.032; -0.008), FM (βˆ = -0.023; 95%CI: -0.035; -0.011), insulin (βˆ = -0.022; 95%CI: -0.036; -0.008) and BP (systolic BP: βˆ = -0.014; 95%CI: -0.025;-0.004; diastolic BP: βˆ = -0.013; 95%CI: -0.020;-0.005), at 10 y. BMI was a mediator between the consumption of un/minimally processed foods and BP. Positive associations were found between consumption of processed foods and the cluster 'higher blood pressure', while an inverse association was described between un/minimally processed and the cluster 'higher blood pressure'. No significant associations were found between the UPF consumption and any cardiometabolic outcomes., Conclusions: High consumption of unprocessed or minimally processed foods has a favourable effect on later children's cardiometabolic health, namely lower body weight and body fat, lower waist circumference, blood pressure insulin serum levels., Competing Interests: Conflict of Interest None., (Copyright © 2022 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Analysis of canine and feline tumor malignancy data can help clinicians identify high-risk patients and make more accurate decisions. Based on a sample of 16,272 cancer records, including 3266 cats and 13,006 dogs, collected from January 2019 to December 2021 in the Vet-OncoNet Network database, this study aimed to compare the tumor malignancy profile between cats and dogs, considering animal-related factors (sex, age, and breed), topography, and geographic location using a mixed-effects logistic regression model. Cats had a higher proportion of malignant tumors (78.7%) than dogs (46.2%), and the malignancy profile was very different regarding tumors' topographies. The mean age of malignant tumors occurred eight months later than benign ones (9.1, SD = 3.4; 9.8, SD = 3.2), in general. Species (OR = 3.96, 95%CI 3.57: 4.39) and topography (MOR = 4.10) were the two most important determinants of malignancy risk. Female dogs had a higher risk than male dogs (OR = 1.19, 95%CI 1.08: 1.31), which does not appear to be the case in cats (OR = 0.98, 95%CI 0.77: 1.23). Breed contributed significantly to differences in malignancy risk in dogs (MOR = 1.56), particularly in pit bulls and boxers. District of residence was not so relevant in predicting malignancy risk (MOR = 1.14). In both species, the risk of malignancy increased by approximately 20% every three years. It could be hypothesized that species differences in genetic structure may contribute to tumor malignancy.
