This paper draws on a three-year ethnographic study during which we investigated young children's cultural development in a Brazilian early childhood centre. A cultural-historical approach was used to understand the concept of autonomy. We focus on Danilo, a very young child who overcame his fear of using a play slide (a cultural artefact). We believe that this process led to his achievement. Our findings suggest that young children's conquests consist of intentional actions that become part of their individual and social identities.

This paper presents the pioneering experience of the Programa Primeira Infancia Melhor (the Better Early Childhood Development Program), also known as "PIM" that has been developed since 2003 in the State of Rio Grande do Sul, Brazil. PIM's goal is to "provide guidance to families, based on their own culture and experiences, to allow them to promote their children's holistic development from pregnancy to six years of age with emphasis on the first three years of life". PIM has been implemented so far in over 200 towns in Rio Grande do Sul through partnerships between state and local governments with technical cooperation provided by the UNESCO Brasilia Office. This paper in addition to outlining the tenets of PIM also presents an updated overview of Brazilian early childhood in terms of education, health and social indicators. Scientific findings in the field of early childhood and results from other programs focusing on this crucial period of development are also discussed in this work.

Globally, an estimated 15 million children are born prematurely each year, resulting in a high burden of under-five mortality and neurodevelopmental disability. Kangaroo Mother Care (KMC) is a key intervention to support the development of preterm infants. However, evidence on the impact of KMC in routine care settings remains limited. This paper examines the associations between maternal KMC efforts and child development among preterm infants using data from a prospective cohort study conducted in São Paulo, Brazil. Study outcomes were height-for-age z-scores (HAZ) and cognitive development at age 3 years. Practicing KMC was positively associated with HAZ (+0.91 SD, 95% CI [0.126, 1.695]), and cognition (+0.37 SD, [0.034, 0.806]) of preterm children. The results suggest that KMC can improve children's cognitive and physical development. New programmes to increase KMC uptake in the setting studied may be beneficial for both mothers and their preterm children.

We studied neurodevelopmental outcomes and behaviours in healthy 2-year old children (N = 1306) from Brazil, India, Italy, Kenya and the UK participating in the INTERGROWTH-21 st Project. There was a positive independent relationship of duration of exclusive breastfeeding (EBF) and age at weaning with gross motor development, vision and autonomic physical activities, most evident if children were exclusively breastfed for ≥7 months or weaned at ≥7 months. There was no association with cognition, language or behaviour. Children exclusively breastfed from birth to <5 months or weaned at >6 months had, in a dose-effect pattern, adjusting for confounding factors, higher scores for "emotional reactivity". The positive effect of EBF and age at weaning on gross motor, running and climbing scores was strongest among children with the highest scores in maternal closeness proxy indicators. EBF, late weaning and maternal closeness, associated with advanced motor and vision maturation, independently influence autonomous behaviours in healthy children.

The objective of this paper is to understand the emotional development of baby cared for in two different contexts: nursery and at home. This research was carried out in Brazil. As recommended by the Bick method, weekly visits were performed at home and in the nursery, always accompanied by transcription and discussion of cases in the supervision group. In this study, a 9-month-old baby was observed for four months. The results point to the construction of the autonomy of the baby, stimulated or not by the caregivers. The concern with care was observed more intensely at home, where the mother had difficulties in dealing with the acquisition of the autonomy of the child. In the nursery, autonomy is stimulated from interaction activities with other children. It should be noted that a good environment, once provided through care, enables new experiences and contributes to the building of emotional development.

Independent locomotion provides autonomy for infants, drastically changing their relationship with their surroundings. From a dynamic systems perspective, the interaction between environment, tasks, and organismic constraints leads to the emergence of new behaviors over time. This 6-month longitudinal study aimed to verify associations between the emergence of locomotor behaviors and infants' characteristics, developmental status, parental beliefs, and practices. This observational study remotely assessed 37 full-term Brazilian infants aged 5 to 15 months, divided into two groups (G1: 5 to 11 months, n = 19; and G2: 9 to 15 months, n = 18). The motor developmental status of infants was closely associated with the emergence of behaviors (p < 0.05). Infants in G2 whose parents agreed with the statement "In typically developing infants, motor development occurs naturally and there is no need to actively stimulate it" started to walk later than those whose parents disagreed. Infants whose parents expected them to walk around 10-11 months walked earlier compared to those expected to walk after 11 months (G2, p = 0.011). Infants in G2 with a high frequency of staying in the supine position started to walk, both with and without support, later than those with a low frequency (p < 0.05). For infants in G1 with a high frequency of playing on the floor, locomotion (p = 0.041) and crawling on hands-and-knees (p = 0.007) started sooner compared to those with a low frequency. Staying in the cradle more frequently was related to a later emergence of supported walk (p = 0.046) among infants in G2. The emergence of locomotor behaviors is associated with motor developmental status, the surfaces where the infant plays, and body position. Parental beliefs and expectations influence how infants are stimulated and, consequently, the emergence of independent walking., 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 Elsevier Inc.

Introduction: The low attendance of families in child developmental follow-up programs for at-risk preterm children is a challenge in Brazil., Objective: This study evaluates the feasibility of implementing a developmental follow-up program for Brazilian preterm infants in a hybrid format., Methods: This is an observational, prospective cohort study, involving preterm infants. Longitudinal developmental test results, the participation frequency in the program, and the number of referrals to early intervention programs were used to assess feasibility. The General Movements (GMs) assessment, Alberta Infant Motor Scale (AIMS) and, Survey of Wellbeing of Young Children (SWYC) Milestones were administered via telehealth. The Bayley-III was administered in-person., Results: Thirty-four preterm infants attended the follow-up until 12 months of corrected age and 18 (52.9 %) concluded all follow-up assessments. Twenty-six (76.5 %) attended all assessments via telehealth, and 26 (76.5 %) attended the in-person assessment. Eighteen (52.9 %) infants showed at least one altered result in development tests. Infants exhibiting abnormal results in the GMs assessment, motor developmental delay according to the AIMS, or developmental delay based on Balley-III were promptly referred to early intervention services., Conclusion: This study demonstrated high participation rate and low dropout in a developmental follow-up program employing a hybrid format. The substantial number of identified infants with developmental delay emphasizes the importance of timely detection of motor delays to referral to early intervention services., Competing Interests: Declaration of competing interest The authors of this manuscript declare no conflicts of interest associated with this paper., (Copyright © 2024 Elsevier B.V.

The aim of this paper is to discuss executive functions and playing games, considering Piaget's work (1967) and the neuropsychological framework (Barkley, 1997, 2000; Cypel, 2007). Two questions guide the discussion: What are the intersections between playing games and the development of executive functions? Can we stimulate children with learning disabilities to build up skills related to executive functioning in a context of games and problem-solving situations? For the last 22 years, researchers from the Institute of Psychology, University of Sao Paulo have been studying children and proposing situations, in which they play games with rules, solve problems, and interact with others (Macedo, Petty & Passos, 1997, 2000, 2005; Souza, Petty, Carvalho, Passos, & Carracedo, 2002). Groups of children from 7 to 11 years old are supervised by professionals who challenge them to develop reasoning and autonomy, which also contribute to develop executive functions. The main point of the project is not to become a good player, but build up skills to surpass difficulties, such as attention, organization, and planning. Participants who were engaged, and did not have serious neurological damages in brain functioning, really became students with better resources to deal with school challenges and they developed more adequate attitudes.

Objective: Studies that have investigated the effect of nutritional counseling during the prenatal period on the follow-up outcomes of children at 6 mo have produced inconclusive results. The present study aimed to investigate the effect of nutritional counseling, based on the NOVA food classification, encouraging the consumption of fresh and minimally processed foods, with overweight adult pregnant women on infant growth at 6 mo of age., Methods: A randomized controlled trial with 195 pairs of pregnant overweight women and their infants at 6 mo of age was conducted in a Brazilian municipality. The pregnant women were allocated to the control group (CG) or intervention group (IG) at the beginning of the pregnancy. The IG received three sessions of nutrition counseling throughout the pregnancy. Linear regression models were used to investigate the effect of the nutritional counseling on infant growth., Results: One hundred ninety-five mother-infant pairs with complete data were included (96 CG, and 99 IG). The mean ± SD infant weight (g) at 6 mo was 7856.1 ± 1.1, and length (cm) was 67.0 ± 2.9. There were no differences in maternal and newborn characteristics between the groups. In the linear regression models, the counseling had no effect on anthropometric parameters of the infants at 6 mo of age: weight-for-length Z-score (β 0.089 [95% CI -0.250; 0.427], P = 0.61); length-for-age Z-score (β 0.032 [95% CI -0.299; 0.363], P = 0.85); weight-for-age Z-score (β 0.070 [95% CI -0.260; 0.400], P = 0.68); BMI-age Z-score (β 0.072 [95% CI -0.270; 0.414], P = 0.68)., Conclusions: There was no effect on infant growth at 6 mo of age after the nutritional counseling during pregnancy. Future studies are needed to confirm this hypothesis., 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 Elsevier Inc.

Research points to the importance of sociocultural and developmental experiences in understanding children's social supports. The present study examines qualitative themes about children's social supports, derived from a multicountry study of 604 school-aged children (ages 4-19 years). Using the ecomap (a child-generated paper-and-pencil drawing depicting relevant stressors and supports), children could describe social stressors and supports in a culturally and developmentally adaptable manner. Participants described 51 support themes reflecting achievement of competencies, degree of autonomy, leisure and recreation activities, and most prominently, interpersonal relationships and interactions. Findings revealed cross-site, cross-gender, and cross-age patterns, and cultural and developmental variations.

In this paper, we suggest that the ability and opportunity to play affords children a natural resource to meet intellectual and emotional challenge. Analysis of case studies focusing on interventions with children caught in the bombing of Beirut, children abandoned to the state system in Romania, and the street children in Rio de Janeiro and Cali is used to support this view. When resources are in deficit, challenge is more likely to become adversity. The impact of adversity is particular to context, but comparison across contexts also shows connections between children's disparate experiences. Analysis confirms that given the opportunity, children interact with and influence their environment through play and that this process provides a resource to meet the challenge of adversity.

Objective: Longitudinal patterns of growth in early childhood are associated with health conditions throughout life. Knowledge of such patterns and the ability to predict them can lead to better prevention and improved health promotion in adulthood. However, growth analyses are characterized by significant variability, and pattern detection is affected by the method applied. Moreover, pattern labelling is typically performed based on ad hoc methods, such as visualizations or clinical experience. Here, we propose a novel pipeline using features extracted from growth trajectories using mathematical, statistical and machine-learning approaches to predict growth patterns and label them in a systematic and unequivocal manner., Methods: We extracted mathematical and clinical features from 9577 children growth trajectories embedded with machine-learning predictions of the growth patterns. We experimented with two sets of features (CAnonical Time-series Characteristics and trajectory features specific to growth), developmental periods and six machine-learning classifiers. Clinical experts provided labels for the detected patterns and decision rules were created to associate the features with the labelled patterns. The predictive capacity of the extracted features was validated on two heterogenous populations (The Applied Research Group for Kids and the 2004 Pelotas Birth Cohort, based in Canada and Brazil, respectively)., Results: Features predictive ability measured by accuracy and F1 score was ≥ 80% and ≥ 0.76 respectively in both cohorts. A small number of features (n = 74) was sufficient to distinguish between growth patterns in both cohorts. Slope, intercept of the trajectory, age at peak value, start value and change of the growth measure were among the top identified features., Conclusion: Growth features can be reliably used as predictors of growth patterns and provide an unbiased understanding of growth patterns. They can be used as tool to reduce the effort to repeat analysis and variability concerning anthropometric measures, time points and analytical methods, in the context of the same or similar populations., 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 Elsevier B.V.

In order to discern the causes of the health and developmental problems of children, and thence develop preventative strategies, longitudinal cohort studies offer major advantages. They can monitor the consequences of exposure to physical and psychological events and thence identify antecedents of various disorders. We describe the historical background to the development in the UK of this study design, and the uptake of longitudinal birth cohorts in low- and middle-income countries (LMICs), using the cohorts in Jamaica, South Africa and Brazil as exemplars. We describe the benefits of such studies and show how undertaking longitudinal cohort studies can have major health and financial benefits to the populations concerned. Additionally, the paper outlines the advantages of collaboration between studies and the pooling of data. [ABSTRACT FROM AUTHOR]

Background: Outdoor air pollution is increasingly recognised as a key threat to population health globally, with particularly high risks for urban residents. In this study, we assessed the association between residential nitrogen dioxide (NO2) exposure and children's cognitive and behavioural development using data from São Paulo Brazil, one of the largest urban agglomerations in the world. Methods: We used data from the São Paulo Western Region Birth Cohort, a longitudinal cohort study aiming to examine determinants as well as long-term implications of early childhood development. Cross-sectional data from the 72-month follow-up was analysed. Data on NO2 concentration in the study area was collected at 80 locations in 2019, and land use regression modelling was used to estimate annual NO2 concentration at children's homes. Associations between predicted NO2 exposure and children's cognitive development as well as children's behavioural problems were estimated using linear regression models adjusted for an extensive set of confounders. All results were expressed per 10 μg/m3 increase in NO2. Results: 1143 children were included in the analysis. We found no association between NO2 and children's cognitive development (beta -0.05, 95% CI [-0.20; 0.10]) or behavioural problems (beta 0.02, 95% CI [-0.80; 0.12]). Conclusion: No association between child cognition or child behaviour and NO2 was found in this cross-sectional analysis. Further research will be necessary to understand the extent to which these null results reflect a true absence of association or other statistical, biological or adaptive factors not addressed in this paper.

Background: Studies with children exposed to methylmercury (MeHg) through fish consumption in the Brazilian Amazon region report that the high levels of hair Hg are associated with significant decreases in intelligence, memory, attention, and visuospatial processing., Objective: To investigate the relationship between mercury exposure and neuropsychological functions in riverside communities of the Brazilian Amazon., Method: 263 participants aged 6 to 14 years old were assessed, from resettlement regions, near the Madeira river, Rondônia, Brazil. To assess the neuropsychological functions we used the following instruments: intelligence (WASI), working memory (Corsi Block-Tapping Task and Digit Span), verbal fluency (Word Generation - NEPSY II), inhibitory control (Inhibition Errors - NEPSY II), shifting (Trail Making Test) and manual motor dexterity (Grooved PegBoard Test). Socioeconomic status was obtained through household surveys. Total Hg levels were quantified hair samples (Total HgH) collected from the occipital region of the scalp and analyzed by Cold Vapor Atomic Absorption Spectrometry., Results: The group in the upper quartile of Total HgH levels presented lower scores on the tasks that assessed estimated IQ, visuospatial working memory, semantic knowledge and phonological verbal fluency, when compared to the group in the lower quartile level. A regression analysis controlled for age, sex, and maternal education showed that for each increase of 10 μg/g of Total HgH, there was a decrease around half standard deviation in Verbal IQ, estimated IQ scores, semantic knowledge, phonological verbal fluency and for verbal and visuospatial working memory., Conclusions: High concentrations of Total Hg in hair were associated with a lower performance in neuropsychological functions tests. The results show that environmental exposure to Hg is associated to children and adolescents' lower neuropsychological performance in the riverine and resettled areas of the Brazilian Amazon region., 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 © 2020 Elsevier B.V.

Background/objective: As a developing country, Brazil presents a wide range of environmental risks that can constitute hazards to child health. The country also presents different socio-economic-cultural conditions that could be responsible for determining different vulnerability and susceptibility levels for the population, which can potentiate the effects of the environmental pollutants. The Rio Birth Cohort Study (PIPA project) is a prospective maternal-infant health study, hosted in the city of Rio de Janeiro (Southeastern Brazil), designed to investigate separate and combined effects of environmental chemical pollutants, as well as the interactions between these exposures and sociocultural environment and epigenetic patterns. This paper presents the learned lessons and strategies to address the shortcomings detected from this pilot study., Methods: The study population will be all children born at the Federal University of Rio de Janeiro Maternity Hospital from July 1st, 2020 to June 30th, 2021. The estimated population is of 2,500 children. The study will collect social, demographic, and health information from pregnant women and their children up to four years of age. Biological samples from both mothers and newborns will be collected to assess metal, pesticide and plasticizer exposure. All newborns will have their landmarks of physical, neurological, psychological, and cognitive development recorded at specific ages., Findings: A pilot study was carried out between September 2017 and August 2018, totaling 142 enrolled pregnant women, leading to 135 (95%) births and the collection of umbilical cord (126-93%,) and mother (139-98%) blood samples, as well as both mother (142-100%) and newborn (54-40%) urine samples and newborn meconium samples (117-86.7%)., Conclusions: The study proposes a comprehensive assessment of pre- and postnatal exposure to environmental chemicals at multiple time points in a population living in a highly urbanized developing country. As far as we know, this is the only birth cohort in Brazil specifically designed for this purpose., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2020 The Author(s).)

Background: The discussion on the safety of thimerosal-containing vaccines (TCVs) and their impact on child development it́s very relevant., Methods: This is a cohort study with mother-child dyads who received prenatal care in the Unified Health System. The domains of motor, cognitive and language development were evaluated in children between 24 and 36 months of age. Data on vaccination were obtained through the child's immunization record. A linear regression analysis was carried out considering possible confounders., Results: In bivariate analyses, motor and language development were associated with TCVs (p < 0.05). However, in the multivariate analysis, this association was not maintained (p > 0.05). These results indicate that the use of TCVs is not associated with child development. The importance of this study is summarized in transmitting relevant information regarding public health, based on reliable data., 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 © 2019 Elsevier Ltd.

This paper assesses the initial psychometric properties of the Denver Developmental Screening Test (Denver II), a widely used child development measure in its first population-level administration in Brazil. The Portuguese version was administered to 2755 children under three years of age who were eligible for a home visiting program in Fortaleza, Northeast Brazil. We examine the measure's internal consistency and verify construct validity by testing the dimensionality through confirmatory factor analysis (CFA) and estimating associations with household socioeconomic variables (e.g., poverty, maternal education, stunting, and parenting practices). The test was found to be psychometrically robust and culturally relevant. Although we found a good fit with the structure proposed by the instrument's author, a structure of two latent variables (motor and cognitive) provided a better fit. This validity exercise provides useful information for policymakers and researchers interested in using this instrument in the Brazilian context or a similar one in the region., (Copyright © 2019 Elsevier Inc.

Background: The aim of the proposed study is to perform a comparative analysis of functional training effects for the paretic upper limb with and without transcranial direct current stimulation over the primary motor cortex in children with spastic hemiparetic cerebral palsy.Methods: The sample will comprise 34 individuals with spastic hemiparetic cerebral palsy, 6 to 16 years old, classified at level I, II, or III of the Manual Ability Classification System. Participants will be randomly allocated to two groups: (1) functional training of the paretic upper limb combined with anodic transcranial stimulation; (2) functional training of the paretic upper limb combined with sham transcranial stimulation. Evaluation will involve three-dimensional movement analysis and electromyography using the SMART-D 140® system (BTS Engineering) and the FREEEMG® system (BTS Engineering), the Quality of Upper Extremity Skills Test, to assess functional mobility, the Portable Device and Ashworth Scale, to measure movement resistance and spasticity, and the Pediatric Evaluation of Disability Inventory, to evaluate performance. Functional reach training of the paretic upper limb will include a range of manual activities using educational toys associated with an induced constraint of the non-paretic limb during the training. Training will be performed in five weekly 20-minute sessions for two weeks. Transcranial stimulation over the primary motor cortex will be performed during the training sessions at an intensity of 1 mA. Findings will be analyzed statistically considering a 5 % significance level (P ≤ 0.05).Discussion: This paper presents a detailed description of a prospective, randomized, controlled, double-blind, clinical trial designed to demonstrate the effects of combining transcranial direct current stimulation over the primary motor cortex and functional training of the paretic limb in children with cerebral palsy classified at level I, II, or III of the Manual Ability Classification System. The results will be published and evidence found may contribute to the use of transcranial stimulation for this population.Trial Registration: ReBEC RBR-6V4Y3K . Registered on 11 February 2015.

Introduction Breastfeeding is an important determinant of child survival and normal growth and development, but breastfeeding prevalence is generally low in Brazil. Factors associated with infant feeding practices there are not well understood. This paper examines factors associated with breastfeeding cessation in a township in the western Brazilian Amazon. Methods A cross-sectional, population-based study was conducted among children younger than 25 months and collected information on maternal and child characteristics. Survival analysis based on a proximal-distal framework examined the association between breastfeeding duration and socioeconomic and maternal/child biological factors. Results The median breastfeeding duration among 101 children who were no longer breastfeeding was 120 days. Almost two-thirds (63 %) of these children stopped breastfeeding before 6 months of age. In the larger sample of 209 children, 74.6 % had previously been bottle-fed. Considering the full proximal-distal model, a child who had ever been bottle-fed was expected to cease breastfeeding about 88 % sooner than one who was never bottle-fed ( p < 0.001). Children in the second-poorest wealth quartile stopped breastfeeding sooner than children in the poorest quartile ( p < 0.05). Discussion Breastfeeding cessation in the study area occurred much earlier than the recommended 2 years of age. Factors associated with ending breastfeeding early included ever-use of a bottle, having a single mother, and belonging to the second-poorest wealth quartile. Further research is needed to better understand these factors and other barriers women face to continuing breastfeeding. [ABSTRACT FROM AUTHOR]

This paper aims to discuss the subjective development process of a child in the classroom, considering aspects that have facilitated school learning. A case study is presented of a second-year student in a public elementary school in Brazil, who, at the beginning of the research, had difficulties with socialization and learning. The theoretical framework used is the Theory of Subjectivity, within a cultural-historical approach, together with its epistemological and methodological proposals, Qualitative Epistemology and the constructive-interpretative method. The main instruments were conversational dynamics and various interactive sessions, which have been expanded to the classroom context, since they generated valuable dialogical, social and relational context. The participant has become active, has gained her place in the classroom, has engaged in activities, and has thus significantly advanced in her learning. The outcomes achieved by the child point to the importance of creating everyday pedagogical strategy contexts which are less expositive and more dialogical, so new networks of relationships favour the coordination of operational processes of learning with processes of subjective development.

This paper describes the main methodological aspects of a cohort study, with emphasis on its recent phases, which may be relevant to investigators planning to carry out similar studies. In 1993, a population based study was launched in Pelotas, Southern Brazil. All 5,249 newborns delivered in the city's hospitals were enrolled, and sub-samples were visited at the ages of one, three and six months and of one and four years. In 2004-5 it was possible to trace 87.5% of the cohort at the age of 10-12 years. Sub-studies are addressing issues related to oral health, psychological development and mental health, body composition, and ethnography. Birth cohort studies are essential for investigating the early determinants of adult disease and nutritional status, yet few such studies are available from low and middle-income countries where these determinants may differ from those documented in more developed settings.

In this paper, we suggest that the ability and opportunity to play affords children a natural resource to meet intellectual and emotional challenge. Analysis of case studies focusing on interventions with children caught in the bombing of Beirut, children abandoned to the state system in Romania, and the street children in Rio de Janeiro and Cali is used to support this view. When resources are in deficit, challenge is more likely to become adversity. The impact of adversity is particular to context, but comparison across contexts also shows connections between children's disparate experiences. Analysis confirms that given the opportunity, children interact with and influence their environment through play and that this process provides a resource to meet the challenge of adversity.

Background/aim: Children with attention deficit hyperactivity disorder (ADHD) have been reported to have play deficits, which can cause problems in occupational development. The aim of this paper was to report research findings on children with ADHD and typically developing children in relation to preference of play partners, play places, toys and type of play. Methods: Thirty-two school aged children from low socioeconomic status were divided into two groups. One group of 16 children with ADHD were matched with 16 typically developing children. Results and conclusion: There were no significant differences between the two groups in relation to play partners, with classmates being the most frequent play partner for both groups. There were significant differences between the two groups in preferred place to play. Children with ADHD preferred to play in school and typically developing children preferred to play on the street. There were significant differences in relation to toys and type of play engaged in with children with ADHD preferring educational materials and typically developing children preferring electronic games. These findings add to knowledge of Brazilian children with ADHD and their play preferences. Comparisons are made with research with Australian children with and without ADHD. [ABSTRACT FROM AUTHOR]

This paper presents the pioneering experience of the Programa Primeira Infância Melhor (the Better Early Childhood Development Program), also known as "PIM " that has been developed since 2003 in the State of Rio Grande do Sul, Brazil. PIM's goal is to "provide guidance to families, based on their own culture and experiences, to allow them to promote their children's holistic development from pregnancy to six years of age with emphasis on the first three years of life". PIM has been implemented so far in over 200 towns in Rio Grande do Sul through partnerships between state and local governments with technical cooperation provided by the UNESCO Brasilia Office. This paper in addition to outlining the tenets of PIM also presents an updated overview of Brazilian early childhood in terms of education, health and social indicators. Scientific findings in the field of early childhood and results from other programs focusing on this crucial period of development are also discussed in this work. [ABSTRACT FROM AUTHOR]

Background: This study aims to present and discuss the psychometric properties of executive functions, which were measured using the TDI-FE instrument. The analysis encompasses its internal structure, potential sensitivity to fatigue factors, relationships with external criteria, and diagnostic accuracy. Methods: The study sample comprised 382 students from Brazil, aged 6–8 years. Child development variables were screened using the TDI-FE and gold standard tests (Cancellation Attention and Trail Making Tests). The proposed scale comprised four activities: a test with fruit images with three tasks, and one memory game. Results: The one-factor model of EF of the TDI-FE failed to fit to the data. However, fit substantially improved once a latent fatigue factor was controlled in the model. The latent factor of EF assessed by the TDI-FE tasks was coherently associated with a series of external variables, including two popular collateral measures of EF. The diagnostic accuracy was reasonable, and a cut-off of 37 points produced 70% of sensitivity and 60% of specificity. Conclusion: Results indicated that the TDI-FE demonstrated sound psychometric properties and diagnostic accuracy, then consisting of an efficient alternative for the assessment of EFs in early childhood education. The study also proved the need to control for response biases such as fatigue in the latent variable models of EF. The TDI-FE is notable because of its low cost and easy application, and it might fulfill a need for instruments for individuals from different contexts at this stage of development in Brazil.

Background: Women living in low- and middle-income countries are more exposed to known risk factors for depression occurrence and persistency over time. Aim: Our aim was to investigate the course of depression in the first 2 years postpartum among Brazilian women enrolled in a cash transfer program. Method: Longitudinal analysis of baseline (T0; mean 3.7 months postpartum) and first follow-up data (T1; mean 18.6 months postpartum) from a trial to assess the impact of a child development promotion program in 30 municipalities from six Brazilian states. The program does not include any interventions against maternal depression. The Edinburgh Postnatal Depression Scale (EPDS) at cutoff ⩾10 was applied. Women were categorized into four groups based on EPDS at T0 and T1: absence of depression, persistence, discontinuity, or emergence pattern. Adjusted Poisson regressions were run using a multilevel hierarchical model. Results: Two thousand eight hundred sixty-three women were assessed. Prevalence of depression was 26.4% [24.8, 28.1] at T0 and 24.4% [22.8, 26.0] at T1. Persistence, discontinuation, and emergence were found in 14.1% [11.3, 17.6%], 12.8% [11.4, 14.3%], and 10.2% [8.0, 13.0], respectively. In adjusted analyses, the persistence pattern was directly associated with parity and inversely associated with schooling of the woman and of the child's father. Living with husband/partner and support from the child's father and family members during pregnancy were protective against persistence. The discontinuity and the emergence patterns were not associated with any of the exposure variables. Conclusions: Depressive symptoms were highly prevalent during the first 2 years postpartum. About half of the women with depression at T1 were persistent cases that could have been detected earlier. Screening for maternal depression should be an essential component in every encounter of women with health professionals in primary health care settings. [ABSTRACT FROM AUTHOR]

Background: Studies assessing the effects of parenting programs have focused on interventions delivered through face-to-face modalities. There is a need for research to evaluate the effects of online parenting programs on child development, such as the BEM Program ('Play Teaches Change' in English), an online play-based parenting program that teaches caregivers on how to introduce playful interactions into their daily household chores. Objective: To assess the effects of the BEM Program on child development and the quality of caregiver-child interaction. Method: A two-arm randomized controlled trial was conducted in a socioeconomically disadvantaged district of São Paulo city in Brazil. 129 children aged 12–23 months and their caregiver were randomly assigned to receive either the BEM Program for 8 weeks (intervention, n = 66) or standard child care (control, n = 63). Data were collected at baseline and endline of the intervention through home visits and online interviews. An intention-to-treat analysis was conducted. Results: The intervention showed positive effects on child development, by improving language development (Cohen's d = 0.20, 95%CI 0.08–0.47) and reduced intrusiveness (Cohen's d = 0.35, 95%CI 0.06–0.65) of caregiver-child interaction. No significant differences were observed in caregiver's repertoire and engagement in age-appropriate play activities with the child while doing the household chores, parenting sense of competence and perceived stress. Conclusions: Despite the small size and low adherence to the program, such promising results advance evidences for fully remote parenting programs and their effects on child development.

This study examined how different domains of social capital and of social support among caregivers are associated with social-emotional development in children ages 4–6 and how caregiver depressive symptoms modify these associations. Using a stratified random sample of preschools, data included a cross-sectional study of 1147 child-caregiver pairs (543 girls) in a low-income municipality in Brazil. Crude and adjusted linear regression models revealed that all domains of social support and two domains of social capital were associated with less social-emotional development delay in children. Given a significant proportion of children in low- and middle-income countries do not meet developmental milestones, strengthening caregiver social capital and support in these settings may have the potential to improve child social-emotional development.

It has become universal to claim a relationship between social cohesion and quality public childcare. The more we invest in our children, the better the return later in life. We explore how childcare is used to strengthen social life by comparing the state role in civilising childcare as described in policy and educational guidelines. At one level, we find that policy intentions are framed by the idea of using childcare to reduce inequalities between people and social groups, and at another by the idea of civilising children to adapt to existing social structures. The analysis unfolds these two sets of intentions by showing how pedagogical ideas of child development become linked to the ways two very different states – Brazil and Denmark – formulate and organise ECEC policies as well as using childcare to bridge between people and social groups, and to civilising children to adapt to existing social structures.

Objective: The Child and Adolescent Behavior Inventory (CABI) is a cost-free 75 question-questionnaire developed by an Italian group to collect information from parents on the behavior of children and adolescents aged 6 to 18 years. It assesses different areas of children’s behavior and psychopathology, including internalizing and externalizing symptoms, and can be used to identify children at risk of mental disorders both in clinical and epidemiological settings. In this study, the authors present a Brazilian-Portuguese adaptation of the CABI and its psychometric properties. Methods: First, the authors conducted a rigorous transcultural adaptation of CABI’s questions and instructions for the Brazilian context. In an online sample of 598 parents, the authors found high reliability (internal consistency) for the CABI’s main subscales. Results: Validity was supported by exploratory factor analysis (the authors found 6 factors representing several aspects of psychopathology both according to the DSM and HiTop models) and significant differences in most CABI’s subscales between children with parent-reported psychopathology and typically developing ones. The present study suggests that the adapted version of CABI is a valid and reliable measure that can be used in Brazil. Conclusions: The CABI can be useful to the pediatrician to get fast but wide information from parents on the behavioral condition of their children or adolescents, and also to decide whether it is appropriate to consult a mental health professional [ABSTRACT FROM AUTHOR]

Parenting practices have been identified as a key determinant of children's developmental outcomes. The aim of this study was to evaluate the association of parenting practices with child development in a cross-sectional population-based study in a low-income state in northeastern Brazil. The study included data on 3566 caregiver–child pairs, and the children were aged 0–66 months. Positive parenting behaviors (PPBs) were conceptualized in areas of interactive play, social development, and speech and language interactions. Child development was evaluated using the Brazilian Ages and Stages Questionnaire. Linear regression analysis was used to assess the relationships. We found that a greater number of PPBs was associated with better child development domain scores. Among infants < 1 year, each additional PPB was associated with a 0.32 standardized mean difference (SMD) greater communication (95% CI: 0.24–0.41) and 0.38 SMD greater problem-solving scores (95% CI: 0.24–0.52). Among children aged 4–6 years old, each additional PPB was associated with improved communication (SMD: 0.22; 95% CI: 0.13–0.32), problem solving (SMD: 0.21; 95% CI: 0.10–0.32) and personal–social domain scores (SMD: 0.26; 95% CI: 0.17–0.36). Our findings indicate that PPB were robustly associated with better outcomes across developmental domains among Brazilian children. Programs and interventions that support PPB can contribute to improvements in development outcomes. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to evaluate the possible association between genetic polymorphisms in DEFB1 (rs1799946 and rs11362) and the development of gingivitis in children from the Amazon region of Brazil. Material and methods: The study included 27 healthy children, 10-12 years old, from public schools in Manaus. For the oral examination, the parameters described in the gingival index of Löe and Silness were used to identify the presence or absence of gingivitis. The dependent variable was categorized as “Yes” for children with gingivitis (experimental group; n=10) and “No” for children without gingivitis (control group; n=17). Genomic DNA was extracted from saliva, the selected polymorphisms in the DEFB1 gene (rs1799946 and rs11362) were genotyped by TaqMan PCR and an endpoint analysis was performed. Genotypic and allelic distribution between groups was performed using the Fisher’s exact test with an established alpha of 5%. Results: It was found that evaluated SNPs in the DEFB1 gene (rs1799946 and rs11362) were not associated with gingivitis (p>0.05). Conclusion: The single nucleotide polymorphisms (SNP) of references rs1799946 and rs11362 in the DEFB1 gene had no function on gingivitis, promoting neither harmful nor beneficial effects, in children.

This article examines the evolution of the understanding of child mental health based on documents that guide nursing practise in Brazil. Eleven relevant documents were submitted to normative analysis, which revealed four themes: Developmental approach of the child mental health; Brazilian policies and social history of children; Spaces for prevention, promotion, and care in children's mental health; and The (in)visibility of nurses' work in the context of mental health. These are linked through ideological and social constructions that have although transformed through the years yet remained the same in their core. Based on our results, we propose adopting a decolonial perspective to compose nursing knowledge to improve child mental health in Brazil. [ABSTRACT FROM AUTHOR]
