Unlabelled: The fetal brain disruption sequence (FBDS), a rare cause of extreme microcephaly, is described in a patient and compared with 19 previously reported cases. Clinical findings present in almost all patients included: severe microcephaly (average occipitofrontal circumference -5.8 SD), overlapping sutures, prominent occipital bone, scalp rugae with normal hair patterning and marked neurological impairment. Early death occurred in 7/20 cases. The FBDS was sporadic in 17 out of 19 reported cases supporting a low recurrence risk for genetic counselling purposes. A group of related observations in cases were thromboembolic phenomenon following death of the co-twin, vascular and/or haematological involvement by prenatal cytomegalovirus infection, prenatal cocaine exposure, direct vascular fetal trauma (cordocentesis) and fetal vascular changes after a maternal car accident causing intracranial bleeding and brain damage. Normal scalp hair pattern in all cases and the second or third trimester location of the disruptive event in two cases suggest that in the FBDS, brain growth is normal throughout the first 18 weeks of gestation at least.Conclusion: Pathogenic factors suggest that different forms of vascular injury to the fetal brain (emboli, haemorrhage, vasoconstriction, disseminated intravascular coagulation) can produce partial brain destruction, diminished intracranial pression and skull collapse in the fetal brain disruption sequence.

Objetivo. Valorar el estado de nutrición de niños que asisten al Instituto Alteño para el Desarrollo de Jalisco en Arandas, Jalisco, y discutir los criterios de clasificación de la desnutrición en México. Material y métodos. Estudio transversal, desarrollado con 775 niños de 12 a 120 meses de edad y que asisten al Instituto Alteño para el Desarrollo de Jalisco (Inadej) y 432 encuestas a niños de nuevo ingreso al Inadej. Se calcularon los índices peso/edad, talla/edad y peso/talla, y se investigaron características sociodemográficas y económicas y hábitos de alimentación; asimismo se compararon los criterios de la Organización Mundial de la Salud (OMS) y de la Norma Oficial Mexicana (NOM-SSA) para definir la prevalencia de desnutrición. Resultados. Hubo baja escolaridad en ambos padres (3.6 años). El ingreso familiar fue de $198 dólares mensuales y cada miembro recibió 0.56 dólar/día para las tres comidas. La prevalencia de desnutrición fue mayor en los tres índices con el uso de la NOM-SSA que con el criterio de la OMS (peso/edad 91.7 vs. 30.9%; talla/edad 66.9 vs. 17.3%; peso/talla 62.5 vs. 9.5% respectivamente). Conclusiones. El índice peso/edad y la NOM SSA sobrestiman la prevalencia de desnutrición y no discriminan entre niños genéticamente pequeños, con desnutrición aguda o desnutrición crónica o pasada. Es más útil el criterio de la OMS. Se deben incluir los índices peso/talla (desnutrición reciente) y talla/edad (desnutrición crónica) para comparación internacional.

Objetivo. Estimar la prevalencia de deficiencia de hierro, yodo y parasitosis en niños que asisten al Instituto Alteño para el Desarrollo de Jalisco (Inadej), Arandas, Jalisco, México. Material y métodos. Estudio transversal efectuado entre 1997 y 1999 con 432 niños de 12 a 120 meses de edad, de nuevo ingreso al Inadej. Se determinaron variables hematológicas, yodo en orina y presencia de parásitos. Se utilizaron las pruebas Ji cuadrada y t de Student en variables no paramétricas y paramétricas. Resultados.

Objective: The aim of the study was to investigate the blood pressure variability during 24 h by using ambulatory blood pressure monitoring (ABPM) in a group of obese and non-obese female adolescents with breast development status 4 and 5 of Tanner's criteria. Methods: A cross-sectional study was conducted at the Cardiovascular Research Institute, Mexico. All subjects underwent 24 h non-invasive ABPM recording device. Pubertal status was determined by breast development. Measurements: office systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Height, weight, body mass index (BMI), waist and hip circumferences, arm circumference, waist to hip ratio (W/H), and skinfold thickness measurements: triceps, subscapular, abdominal and supraspinal. Results: Fifty-nine adolescents 13-16 years old; 29 obese (BMI 31.2 ± 4.0), and 30 non- obese (BMI 21.2 ± 2.2). Obese vs. non-obese: Office SBP 116.9 vs. 105.9 ± 9.3 mmHg (p < 0.001); ABPM in 24 h: SBP 113.8 ± 6.3 vs. 107.6 ± 5.7 mmHg (p < 0.001); diurnal SBP 117.3 mmHg vs. 111.2 mmHg (p < 0.001); nocturnal SBP 105.5 ± 8 vs. 99.4 mmHg; absolute variability in 24 h DBP 10.0 ± 1.8 vs. 8.7 ± 1.5 (p < 0.003); coefficient of variation 24 h DBP 17.3 ± 3 vs. 15.4 ± 2.6% (p < 0.05); systolic non-dipper 16 (55.2%) vs. 9 (30%) (p < 0.05); pulse pressure 24 h 49.3 ± 8 vs. 43.5 ± 9 mmHg (p < 0.01). Conclusion: Obese adolescents are presenting changes in BP variability during 24-h in comparison with nonobese adolescents; it also includes higher pulse pressure. Thus, these can be early indicators for the development of hypertension or other cardiovascular diseases in the adult life. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: the combination of cesarean section delivery and limited exposure to full breastfeeding (FBF) in the first six months of life may increase the risk of obesity and diabetes mellitus. This study aimed to establish an association between type 2 diabetes mellitus (T2DM) in adulthood, cesarean section delivery and incomplete full breastfeeding (FBF) in individuals from the metropolitan area of Guadalajara, Mexico. Methodology: this analytical cross-sectional study included patients over 18 years of age with T2DM and normal weight, overweight or obesity, regardless of sex. Informed consent was obtained. Variables encompassed T2DM, type of delivery method, first-year diet, family history, demographic, socioeconomic, and educational characteristics, and anthropometric measurements. For statistical analysis, Student's t test, chi-square tests and odds ratios were employed. Results: the study evaluated 218 patients with an average age of 57.8 years (± 12.7) and an average age at T2DM diagnosis of 46.2 years (± 12.5). FBF (65.6 %) and partial breastfeeding (PBF) (23.8 %) prevailed in the first six months. The average age at T2DM diagnosis was 46.7 years (± 12.1) for vaginally born patients and 30.7 years (± 15.5) for cesarean-born patients (p = 0.001). Cesarean delivery increased obesity risk by nine times in patients with T2DM [OR = 8.9 (CI, 1.05, 75.2), p = 0.02]. Conclusion: prioritizing the limitation of nonmedically justified cesarean section deliveries is crucial to mitigate the risk of obesity and T2DM in adulthood. .

Background/objectives: Neck circumference (NC) has been proposed as a simple measurement to identify patients with overweight and obesity. It has been found that adipose tissue at the cervical level is associated with the presence of metabolic alterations. The aim of this study was to estimate the association between NC and indicators of Metabolic Syndrome (MS) to subsequently estimate its capacity to identify the risk of MS compared to waist circumference (WC) and Body Mass Index (BMI)., Methods: A cross-sectional study was carried out with a sample of 286 children 6-9 years old who attended six public primary schools in Jalisco, Mexico. Pearson's correlation coefficients along with sensitivity and specificity tests were performed to analyze the relationship between NC and MS indicators. Odds ratio (OR) and concordance analyses were performed considering the Kappa index., Results: NC showed statistically significant correlations with all MS indicators except for LDL cholesterol and total cholesterol. The cut-off points of NC to identify MS according to sex was >27.4 cm for girls and >29.8 cm for boys. The association of NC with values above the cutoff point and the presence of MS was OR: 21.6 (CI: 7.11-65.74)., Conclusions: NC represents a simple and cost-effective alternative to identify children at risk of MS when compared to BMI and WC.

Background: Neck circumference (NC) has been proposed as an indicator of upper trunk adiposity and a potential indicator of metabolic risk. The objective was to evaluate NC and its correlation with body fat percentage (BF%) and other indicators of adiposity in children with normal weight, overweight, and obesity., Methods: In a cross-sectional study, 112 children 5 to 10 years of age were included in the outpatient clinic from a public hospital. Measures of weight and height to calculate BMI (kg/m 2 ), NC, mid-upper arm circumference, waist circumference, and tricipital skinfold thickness. Body composition measurements were performed using an electrical bioimpedance device (BIA). The relationship between anthropometric variables and BF% obtained by BIA was determined using Spearman correlation tests. Multivariate models were constructed with BF% as the dependent variable and anthropometric parameters as independent., Results: In the entire group, there was a direct correlation between NC and BF% (r = 0.50, p < 0.001), but lost statistical significance in the case of normal weight. The relationship maintained its significance in subjects from the overweight and obesity groups. In multivariate models, BMI exhibited the highest correlation with BF%, followed by waist circumference and mid-upper arm circumference; for NC, the R 2 value was 0.30 ( p < 0.001)., Conclusions: Neck circumference is useful in the screening of population groups with the advantage of not requiring any specialized instruments for its measurement other than a tape measure. BMI and waist circumference were the best indicators of general and central adiposity, respectively.

Introduction: Background: infants receiving full breastfeeding (FBF) regulate their appetites differently from those receiving human milk substitutes (HMS). In addition, early exposure to the dietary cholesterol in human milk could lead to better cholesterol regulation in later stages of life. Therefore, the purpose was to compare lipid profiles in 4-month-old infants and to correlate lipid profile with anthropometric indicators and appetite-regulating hormones according to the type of feeding. Methods: this was a cross-sectional and correlational study, which included 145 mother-infant dyads according to the type of feeding; 64 received FBF, 47 partial breastfeeding (PBF), and 34 HMS. The complete lipid profile, total ghrelin, leptin, peptide YY, and glucagon-like peptide type 1 were measured. Z-scores for weight/age, length/age, weight/length, triceps (TSF) and subscapular folds (SSF) and body mass index for age were also obtained. Results: there were significant differences in triglycerides and LDL cholesterol according to the type of feeding. In the HMS group, an inverse relationship was observed between ghrelin and triglycerides (p = 0.038), ghrelin and total cholesterol (TC) (p = 0.026), and peptide YY and HDL cholesterol (p = 0.017). In the PBF group, a direct relationship was observed between length/age (z) and triglycerides (p = 0.001) and between subscapular folds and TC (p = 0.049). In infants receiving HMS, a direct correlation was observed between weight/age (z) and TC (p = 0.045) and between length/age (z) and LDL cholesterol (p = 0.010). Conclusion: these findings show a relationship between growth, energy reserve, lipid profile, and modulation of appetite-regulating hormones according to the type of feeding they received.

Objective: To review the available evidence on the early introduction of allergenic foods and the possible protection in the development of food allergy in later stages., Methods: An exploratory review of randomized clinical trials whose study population included infants less than 6 months of age at enrollment with or without a diagnosis of food allergy was conducted. For the purposes of this review, eggs, peanuts, and wheat were included as potentially allergenic foods. The following databases were consulted: Medline, EBSCO, OVID, Science Direct and JSTOR (Journal Storage), Scielo, LILACS, Redalyc and Imbiomed from August to December 2021., Results: 429 articles were identified, 412 were excluded, and the final analysis included 9 studies that met the inclusion criteria. Six trials correspond to allergy to eggs, two to peanuts and one to wheat. The age of introduction differs in all trials. The earliest exposure was at 3.5 months and the latest at 5.5 months. The reduction in the risk of developing food allergy occurred in children at risk of allergy. Adverse reactions were common, particularly with the introduction of egg., Conclusions: We found no evidence that early introduction (< 6 months of age) of allergenic foods reduces the risk of developing food allergy in infants without risk factors.

Objective: To assess whether automated office blood pressure (BP) (AOBP) measurement is a better method for measuring BP in the office than conventional techniques and an alternative to out-of-office BP measurements: home-self BP (HSBP) or ambulatory BP monitoring (ABPM)., Methods: We conducted a cross-sectional study of 74 patients and compared AOBP with the conventional technique using a mercury sphygmomanometer and with both out-to-office BP measurements: HSBP of 7 days (three measurements in the morning, afternoon, and night) and daytime ABPM. In addition, we compared BP values obtained using HSBP and ABPM to determine their level of agreement. We used ANOVA to compare means, Bland-Altman, and intraclass correlation coefficients (ICC) for concordance., Results: BP values obtained by the two office methods were similar: conventional 147.2/85.0 mmHg and AOBP 146.0/85.5 mmHg ( P > 0.05) with good agreement (ICC 0.85). The mean SBP differences between AOBP and HSBP ( P < 0.001) and between AOBP and ABPM ( P < 0.001) were 8.6/13.0 mmHg with limits of agreement of -21.2 to 38.5 and -18.4 to 44.3 mmHg, respectively. The average SBP values obtained by HSBP were 4.3 mmHg higher than those obtained by ABPM ( P < 0.01)., Conclusion: Our study showed good agreement and concordance between the two office methods as well between the two out-to-office methods, although there was a significant difference in the mean SBP between the HSBP and ABPM. Moreover, AOBP was not comparable to either HSBP or ABPM; therefore, the estimation of out-to-office BP using AOBP is not supported., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: There is a possibility that excess body fat affects bone mass gain and may compromise skeletal health in obese children. The purpose of the study was to identify the relationship between bone mineral density (BMD) and body composition in normal weight, overweight and obese children., Methods: This was a cross-sectional study of 6- to 11-year-old children who attended the hospital's outpatient clinic. They were apparently healthy and had no history of prematurity, low birth weight, or chronic diseases. Body mass index (BMI) was used to identify subjects as normal weight, overweight or obese. BMD and body composition were assessed by dual energy X-ray absorptiometry. The BMD values (total and lumbar spine) were compared between normal weight, overweight and obese children. Correlation coefficients were calculated, and multivariate models were performed., Results: Forty-nine children were included: 16 with normal weight, 15 that were overweight and 18 with obesity; the mean age was 8.4 ± 1.7 years. All the participants had a normal BMD (> - 2 SD). BMD was higher in obese children and had a positive correlation with total and trunk lean mass in the three study groups (p < 0.001). In obese children, an inverse correlation of lumbar spine BMD (Z score) with total and trunk fat mass (p < 0.05) was identified. In the multivariate models (with the whole group), the total lean mass was the only significant variable that explained BMD variability., Conclusions: BMD in obese children was higher than that in normal weight children, which is explained by their greater lean mass and not by excess body fat. In obese children, a higher fat mass was related to a lower lumbar spine BMD. Lean mass had a direct correlation with BMD in the three study groups and was the most important predictor of BMD, reflecting the importance of strengthening the muscular system through performing physical activity and practicing a healthy lifestyle., (© 2022.

Background: It has been pointed out that ghrelin and obestatin could have an impact on the genesis of obesity, since they estimulate and inhibit apetite and, therefore, food consumption., Objective: To compare the metabolic profile, lipid profile and the concentrations of ghrelin and obestatin in children with normal weight or obesity., Material and Methods: Cross-sectional design with 97 normal weight or obese children, 6 to 18 years of age, who did not present systemic diseases. The serum concentrations of glucose, insulin, total cholesterol, triglycerides, high (HDL), low (LDL) and very low density (VLDL) lipoproteins, aspartate aminotransferase (AST), alanine aminotransferase (ALT), ghrelin and obestatin were determined. Descriptive statistics were performed. Student's t test was used to compare groups, and correlation coefficients of ghrelin and obestatin values with biochemical and anthropometric variables. A p value of ≤ 0.05 was significant., Results: 55 children with normal weight and 42 with obesity were included; mean age was 10.7 years. Triglycerides, LDL, VLDL, ALT and insulin were higher, and HDL lower in obese children (p < 0.05). Ghrelin values were higher in normal weight children (p < 0.05), and there was no difference in obestatin values., Conclusions: The lower concentration of ghrelin in obese children may indicate a negative feedback to regulate energy consumption. Children and adolescents with obesity show metabolic and lipid profile alterations that place them at risk of early development of cardiovascular risk factors., (© 2022 Revista Medica del Instituto Mexicano del Seguro Social.)

The Child Eating Behaviour Questionnaire (CEBQ) and the Adult Eating Behaviour Questionnaire (AEBQ) measure 'food approach' [Food responsiveness (FR); Emotional overeating (EOE); Enjoyment of food (EF); Desire to Drink] and 'food avoidant' [Satiety responsiveness (SR); Emotional undereating (EUE); Food fussiness (FF); Slowness in eating (SE)] appetitive traits (ATs) in children and adults, respectively. 'Food approach' traits predispose to overweight while 'food avoidance' traits provide protection, but little is known about the relationships between parents' and their offspring's ATs. The aim was to examine the associations between maternal and child appetitive traits, using the AEBQ-Esp and CEBQ-Mex adapted for use in Mexican populations. Sociodemographic data, weights and heights of mothers and their children (aged 3-13 years), who were recruited from a teaching hospital in Guadalajara, Mexico, were measured. Mothers completed both the AEBQ-Esp and the CEBQ-Mex. The CEBQ-Mex was developed, and its reliability was tested using Cronbach's alpha and Omega, and Confirmatory Factor Analysis (CFA) was used to assess its validity. Pearson's correlation coefficients were used to assess associations between mothers' and children's Ats. The sample included 842 mother-child dyads (mother's mean age = 34.8±SD6.9 years, BMI 29.7±6.1 kg/m2; children's mean age = 8.5 ±SD2.5 years, BMIz 1.5±1.6). Internal reliability was moderate to high [Cronbach alpha = .68-.86; Omega = .71-.87] for the CEBQ-Mex and validity was confirmed for an 8-factor model through CFA [RMSEA = 0.065; CFI = 0.840, NFI = 0.805; IFI = 0.842; and χ2(df = 532) = 2939.51, p < 0.001]. All but one of the children's appetitive traits showed small to moderate, significant correlations with their mother's counterpart [FR (r = .22; p<001); EOE (r = .30; p < .001); EF (r = .15; < .001); SR (r = .16; p < .001); EUE (r = .34; p < .001) and FF (r = .14; p < .001). Only SE was not significantly associated with maternal SE (r = .01; p>.05). ATs tend to run in families, signalling the intergenerational transmission of eating behaviours. These may be useful targets for family-wide interventions to support the development and maintenance of healthy eating behaviours in childhood., Competing Interests: The authors declare that they have no competing interests.

Purpose: Appetitive traits in adults and their associations with weight can be measured using the Adult Eating Behaviour Questionnaire (AEBQ). The aim of this study was to confirm the factor structure of the Spanish AEBQ (AEBQ-Esp) in a Mexican sample and explore associations between the eight traits with body mass index (BMI)., Method: A sample of 1023 adults, mean age of 36.8 ± 12.8 years, was recruited from Guadalajara, Mexico. Researchers weighed and measured participants, and they completed the AEBQ-Esp either online or in paper format and reported sociodemographic data. To test two alternative factor structures (eight factors including Hunger; seven factors excluding Hunger), confirmatory factor analysis (CFA) was used. Internal reliability was assessed using Cronbach's alpha; test-retest reliability was assessed using intra-class correlation coefficients. Multivariate linear regressions were used to test for associations between the AEBQ subscales and BMI, adjusted for age, sex, format of AEBQ responses, education, marital and employment status., Results: A seven-factor structure was the best model fit using CFA, excluding the Hunger subscale but similar to the original AEBQ. Internal reliability was good for all subscales (Cronbach's α = 0.70-0.86), and the intra-class correlation coefficient (0.70-0.91) reflected good test-retest reliability. In the fully adjusted models, Satiety Responsiveness [β = - 0.61; (- 1.01, - 0.21)] and Slowness in Eating [β = - 0.70; (- 1.01, - 0.39)] were negatively associated with BMI, and Emotional Over-Eating [β = 0.94; (0.62, 1.27)] was positively associated with BMI., Conclusions: The AEBQ-Esp (excluding Hunger) appears to be a valid and reliable psychometric questionnaire for measuring appetitive traits in a Mexican Spanish-speaking population. Some traits appear to be associated with BMI in adulthood and warrant further exploration., Level of Evidence: Level III evidence obtained from well-designed cohort or case-control analytic studies. Although this was just an observational study, it was well designed and provided new evidence., (© 2021. The Author(s).)

La creciente epidemia de obesidad ha sido uno de los retos más importantes de salud pública en México durante los últimos años. Con apoyo de la Federación Mundial de Obesidad, en 2021 formamos un grupo de profesionales para identificar y resumir las acciones prioritarias en las que puede enfocarse nuestro país para hacer frente a esta epidemia. Al proceso de desarrollo y discusión de este grupo se sumaron más de 1 000 profesionales de la salud para retomar recomendaciones de documentos y guías de alto nivel previamente publicados. En conmemoración del Día Mundial de la Obesidad, en este 2022 se presenta esta postura como insumo para el desarrollo de acciones en el ámbito profesional y de los diferentes sectores, en la que se incluyen 10 recomendaciones de acción, desde la perspectiva poblacional hasta la atención individualizada, y se enfatiza en la importancia de la participación social, de las intervenciones integrales con visión centrada en la persona y de la sostenibilidad planetaria, además de mejorar la educación y las campañas de difusión, propiciar un ambiente promotor de entornos activos y blindar de conflictos de interés los esfuerzos de prevención y control. La postura hace un llamado para abordar la obesidad de manera seria, con base en la evidencia científica, oportuna e integral, con enfoque de curso de vida, de forma ética y sensible, y sin perpetuar las barreras del estigma de peso en la sociedad.

Neck circumference was studied for the first time in a pediatric population in 2010. Since then, various countries have proposed cutoff values to identify overweight, obesity, and metabolic syndrome. However, no reference values have been established for the Mexican child population. The aim of this study is to provide percentile reference values for the neck circumference of Mexican schoolchildren. Only normal-weight schoolchildren aged 6-11 years were included. Percentiles and growth charts were constructed based on the "Generalized Additive Model for Location, Scale and Shape" (GAMLSS). A total of 1059 schoolchildren (52.9% female) was evaluated. Weight, height, and BMI values were higher for males; however, this difference was not statistically significant. The 50th percentile for females was 24.6 cm at six years old and 28.25 cm at 11 years old, and for males, it was 25.75 cm and 28.76 cm, respectively. Both males and females displayed a pronounced increase in neck circumference between 10 and 11 years of age. The greatest variability was found in the 11-year-old group, with an increase of 5.5 cm for males and 5.4 cm for females. This study presents the first reference values for neck circumference for a Mexican child population.

It has been accepted that satiety- and appetite-stimulating hormones play a role in the regulation of food intake and body composition during and after the lactation stage. Therefore, the purpose was to demonstrate that serum appetite-regulating hormones in infants differ according to anthropometric indicators and type of feeding. In a nonrandom cohort study, 169 mother-newborn dyads whose pregnancy and birth were attended at the Hospital Civil de Guadalajara were enrolled. According to the type of feeding, infants were classified as full breastfeeding (FBF), partial breastfeeding (PBF), and infants receiving human milk substitutes (HMS). Serum concentrations of ghrelin (pg/ml), leptin (ng/ml), peptide YY (pg/ml), and glucagon-like peptide-1 (GLP-1) (pM) were measured. Anthropometric measurements including weight, length, cephalic, arm circumference, tricipital, and subscapular skinfolds were obtained. Weight/age, weight/height, height/age, and BMI Z -score indexes were estimated. We performed one-way ANOVA, unpaired Student's t test, post hoc Tukey test, and Pearson correlation tests. The ANOVA comparison of the three feeding types showed significant differences in most anthropometric indicators ( z -scores), especially between infants receiving FBF versus HMS and particularly on indicators of adiposity; no differences were observed in length and cephalic circumference z -scores at 8th and 16th weeks. Further, significant correlations were found between most of the adiposity indicators with ghrelin, leptin, and GLP-1, especially in infants who received FBF. There were differences in anthropometric and body composition parameters among infants receiving FBF, PBF, and HMS. There were significant correlations between body composition indicators with ghrelin, leptin, and GLP-1 mainly in infants receiving FBF., Competing Interests: All authors involved in these work disclose any potential sources of conflict of interest related to patent or stock ownership, membership of a company board of directors, membership of an advisory board or committee for a company, and consultancy for or receipt of speaker's fees from a company., (© 2020 The Authors.

Background: Overweight and obesity in schoolchildren are a major public health problem in Mexico. The objective of this study was to demonstrate the association of appetitive traits with the presence of obesity and identify gender differences in children attending a university hospital., Methods: A cross-sectional study was conducted on 176 children with obesity and 175 children with normal weight in the outpatient clinic of the Nuevo Hospital Civil de Guadalajara. The body mass index (BMI) of the participants was calculated. The parents completed the Children's Eating Behaviour Questionnaire to measure eight appetitive traits. The mean appetitive trait scores were compared between children with obesity and normal weight, and between genders. Statistical analysis was performed using Student's t-tests for independent samples and regression analysis between appetite traits and BMI Z-scores., Results: The mean food responsiveness score (or food onset appetitive trait) was higher in children with obesity (p < 0.001), while the mean satiety responsiveness (or food offset trait) was higher in children with normal weight (p < 0.001). Normal weight males showed higher scores for Food responsiveness, Emotional over-eating, and Desire to drink (p < 0.05)., Conclusions: Children with obesity show appetitive traits that could lead to higher food consumption. Normal weight males showed appetitive traits that could represent a risk of developing obesity., (Copyright: © 2020 Permanyer.)

Lactose is a unique component of breast milk, many infant formulas and dairy products, and is widely used in pharmaceutical products. In spite of that, its role in human nutrition or lactose intolerance is generally not well-understood. For that reason, a 2-day-long lactose consensus meeting with health care professionals was organized in Mexico to come to a set of statements for which consensus could be gathered. Topics ranging from lactase expression to potential health benefits of lactose were introduced by experts, and that was followed by a discussion on concept statements. Interestingly, lactose does not seem to induce a neurological reward response when consumed. Although lactose digestion is optimal, it supplies galactose for liver glycogen synthesis. In infants, it cannot be ignored that lactose-derived galactose is needed for the synthesis of glycosylated macromolecules. At least beyond infancy, the low glycemic index of lactose might be metabolically beneficial. When lactase expression decreases, lactose maldigestion may lead to lactose intolerance symptoms. In infancy, the temporary replacing of lactose by other carbohydrates is only justified in case of severe intolerance symptoms. In those who show an (epi)genetic decrease or absence of lactase expression, a certain amount (for adults mostly up to 12 g per portion) of lactose can still be consumed. In these cases, lactose shows beneficial intestinal-microbiota-shaping effects. Avoiding lactose-containing products may imply a lower intake of other important nutrients, such as calcium and vitamin B 12 from dairy products, as well as an increased intake of less beneficial carbohydrates.

Objective: Obesity is clearly associated to kidney disease in adult population; however, there is scarce evidence in children and adolescents. The aim was to compare frequency of renal damage according to the presence of overweight-obesity in children and adolescents, as well as to compare nutritional and biochemical risk factors, according to the presence of kidney alterations., Methods: Cross-sectional study; 172 children and adolescents, 6-16 years old, without malnutrition, diabetes mellitus, hypertension and independent comorbid conditions associated to obesity or kidney disease, as well as transitory causes of microalbuminuria (MA) from a Primary Health-Care Unit were included. Clinical, biochemical, anthropometric and dietetic evaluations were measured in all subjects; subsequently they were classified as normal weight, overweight and obesity groups according to sex- and age-adjusted body mass index (BMI). Glomerular filtration rate (GFR, estimated by Schwartz equation) and albuminuria (albumin/creatinine ratio) were determined. Presence of kidney alterations was measured as decreased GFR (<90 mL/min/1.73m 2 ), hyperfiltration (>170 mL/min/1.73m 2 ) and MA (30-300 mg/g)., Results: Compared with controls, subjects with overweight-obesity had significantly (P<.05) abdominal obesity (0 vs 69%), hypertension (19 vs 26%), hypertriglyceridemia (11 vs 47%), high low-density lipoprotein cholesterol (2 vs 8%) and low high-density lipoprotein cholesterol (HDL-cholesterol; 2 vs 28%), hyperuricemia (11 vs 28%) and hyperinsulinemia (8 vs 70%). Hyperfiltration and MA were present in 5 and 4 subjects with overweight/obesity, respectively, whereas decreased GFR was present in only 1 subject with obesity. Normal weight subjects had no kidney alterations. In multivariate analysis, kidney alterations were significantly predicted by higher BMI and lower HDL-cholesterol., Conclusions: Kidney alterations were observed only in subjects with overweight (3.6%) and obesity (9.9%), who additionally, displayed cardiometabolic and kidney disease risk factors more frequently than normal weight subjects., (Copyright © 2018 National Kidney Foundation, Inc.

Introduction: Introduction: children with cerebral palsy (CP) have multiple risk factors for low bone mineral density or osteoporosis. Objective: to explore the association between bone mineral density (BMD) and biochemical and hormonal indicators of bone metabolism in children with quadriplegic cerebral palsy (CP). Methods: a cross-sectional analytical study included 59 participants from six to 18 years of age with quadriplegic CP. Serum concentrations of calcium, phosphorus, 25OHD metabolite, parathyroid hormone (PTH), alkaline phosphatase, and thyroid hormones were determined using standardized methods. The BMD measurement was obtained from the lumbar spine expressed in g/cm2 and Z-score. Unpaired Student's t-test, Chi-square test, odds ratio and Pearson's correlation were performed. Results: participants with CP and malnutrition had lower serum concentrations of calcium, phosphorus and alkaline phosphatase. Those who had low BMD showed lower serum concentrations of calcium, phosphorus and alkaline phosphatase. Most participants with low and normal BMD had vitamin D deficiency (27.1% and 10%) and insufficiency (35.4% and 30%), respectively. There was a significant correlation between BMD and serum concentrations of calcium, phosphorus, alkaline phosphatase, vitamin D and thyroid-stimulating hormone (TSH). There were no differences in the biochemical and hormonal indicators by level of gross motor function, use of anticonvulsants and oral versus enteral feeding method. Conclusion: malnutrition and alteration of vitamin D nutritional status were associated with low BMD and alterations of biochemical indicators of bone metabolism in pediatric patients with quadriplegic CP. The relationship between BMD and biochemical indicators of bone metabolism in children with quadriplegic CP was also demonstrated.

Objective: We aimed to study the correlation between neck circumference (NC) and anthropometric adiposity indicators, and to determine cut-off points of NC for both sexes to identify elevated central adiposity in schoolchildren in western Mexico., Design: Cross-sectional study., Setting: Rural settings in western México.ParticipantsChildren from a convenience sample of six schools in Acatlán, Jalisco, Mexico (n 1802)., Results: NC showed a strong positive correlation with all anthropometric adiposity indicators in both sexes, which were notably higher in boys regardless of age. Noteworthy, waist circumference displayed the highest significant correlation when analysed by both age and sex. As age increased, NC cut-off points to identify elevated central adiposity ranged from 25·7 to 30·1 cm for girls and from 27·5 to 31·7 cm for boys., Conclusions: NC could be used as a simple, inexpensive and non-invasive indicator for central obesity assessment in Mexican schoolchildren.

Introduction: Introduction: the purpose of this study was to evaluate the relationship of arm anthropometric indicators with direct indicators of nutritional status in hospitalized pediatric patients. Methods: an analytical cross-sectional study with 760 patients hospitalized in the Pediatric Division of the Nuevo Hospital Civil de Guadalajara during 2014 was used. The anthropometric indices were weight/length, weight/height, weight/age, length/age, height/age, head circumference/age and body mass index (BMI)/age. The arm indicators were mid-upper arm circumference (MUAC), total arm area (TAA), arm muscle area (AMA), arm fat area (AFA) and fat percentage (FP). The ANOVA, Kruskall-Wallis, Mann-Whitney U and Pearson's correlation tests and also odds ratios were used to identify the probability of nutritional status impairment. Results: the prevalence of acute and chronic malnutrition was higher in infants (31% and 30%, respectively). With arm areas (TAA, AMA, AFA), the risk of deficit (≤ -2DE) was higher in infants and early preschoolers (p < 0.001). The correlation between the anthropometric indexes and the arm areas was direct and significant (p < 0.001). The BMI variability was explained in 68% by the AMA, AFA, and FP (p < 0.001); the variability of the height/age index was also explained in 34% by the AMA and AFA (p < 0.001). Conclusion: it is possible to diagnose both a chronic and acute deficit using the indirect indicators of the arm, while the body mass index only reflects an acute deficit. Therefore, arm areas would be more useful indicators in the assessment of nutritional status and the diagnosis of chronic-acute malnutrition in hospitalized pediatric patients.

Satiety and appetite-stimulating hormones play a role in the regulation of food intake. Breastfed infants may have a different profile of serum appetite-regulating hormones than formula-fed infants. We propose to demonstrate that the serum concentration of appetite regulatory hormones differs according to the type of feeding and that there is a correlation between the serum concentrations of these hormones in mothers and in infants at 4 months of age. In a cross-sectional analysis, 167 mother-newborn dyads at the Hospital Civil de Guadalajara were enrolled: 74 full breastfeeding (FBF), 56 partial breastfeeding (PBF), and 37 receiving human milk substitutes (HMS). Serum levels of ghrelin (pg/ml), leptin (ng/ml), peptide YY (pg/ml), and glucagon-like peptide-1 (GLP-1) (pM) were measured. We performed one-way analysis of variance, unpaired Student t test, post hoc Tukey test, and Pearson correlation. The total sample at 16 weeks postpartum included 167 dyads. The mean age was 16 ± 1 weeks. The concentrations of GLP-1 (pM) and peptide YY (pg/ml) were higher in the FBF group (42.6 and 442.9) than in the HMS group (35.2 and 401.9), respectively, p  =   0.046 and p  =   0.056. And, the FBF group had higher correlation coefficients of ghrelin ( r  =   0.411 vs. 0.165), GLP-1 ( r  = 0.576 vs. 0.407), and peptide YY ( r  = 0.218 vs. 0.067), respectively, than the HMS group. The concentrations of GLP-1 and peptide YY were higher in the FBF group when compared with the HMS group. Mother-infant dyads fed by FBF had more significant direct correlations of appetite-regulating hormones than those who received HMS., Competing Interests: None.

Objective: The objective of the study was to demonstrate that there are differences in the factors associated with anthropometric indicators of nutritional status, with particular emphasis on arm indicators, in children with end-stage kidney disease undergoing peritoneal dialysis (PD), hemodialysis (HD), and after kidney transplant (KT)., Methods: An analytical cross-sectional study of consecutive cases included 130 children and adolescents with end-stage kidney disease undergoing substitutive treatment: 49 patients who underwent KT, 33 undergoing PD, and 47 undergoing HD. Socioeconomic data were obtained from all the 3 groups; anthropometric indicators of nutritional status were calculated. Student's t-test and analysis of variance were used for parametric variables. Chi-square test, Mann-Whitney U test, Kruskal-Wallis test, and odds ratio (OR) were used for nonparametric variables., Results: The number of parents living as couples was higher for patients who underwent KT (OR = 3.5 [95% confidence interval {CI} 1.34-9.0]) and undergoing PD (OR = 3.0 [95% CI 1.06-8.8]) than those undergoing HD. The number of mothers who worked outside the home was higher for patients who underwent KT and undergoing PD than the mothers of patients undergoing HD (OR = 13.7 [95% CI: 4.56-41.05]; OR = 15.4 [CI 95% 4.8-49], respectively). Family income was higher for patients who underwent KT and undergoing PD (P = .019, P = .093, respectively). More than 40% of patients in all the 3 groups had growth impairment. Body mass index, mid-upper arm circumference, tricipital and subscapular skinfolds, total arm area, and arm fat area were affected in HD and PD groups (9 to 40%), while of the patients who underwent KT, 36.7% were overweight or obese. More than 50% of patients who underwent KT and undergoing HD and PD had involvement in the arm muscular area., Conclusions: Socioeconomic conditions are more influential for children in the HD program. The nutritional status of children after KT improves; however, not all anthropometric indicators are fully recovered. Children after KT are up to 9 times more likely to be overweight or obese., (Copyright © 2018 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.)

Introduction: proper estimation of energy requirements in children with cerebral palsy (CP) is essential in ensuring that their energy needs are optimally met., Objective: therefore, the purpose of this study was to demonstrate that resting energy expenditure (REE) and total energy expenditure (TEE) are associated with age, anthropometric indicators and body composition in children with spastic cerebral palsy., Methods: a cross-sectional study included 79 participants with spastic CP from 24 months to 16 years nine months. Weight and height (estimated by lower leg length) were obtained; body composition and energy expenditure were estimated by bioelectrical impedance analysis. ANOVA, post hoc tests, the Pearson correlation and determination coefficients (R2) were performed., Results: significant gradual increases according to age in REE and TEE (both in kcal/d) were observed. There were highly significant positive correlations between REE and TEE (kcal/d, kcal/cm/d) with fat-free mass (FFM) and fat mass (FM), but negative correlations between REE (kcal/ kg/d) with body composition and energy indicators. FFM and total body water, and to a lesser extent FM, explained a high percentage of the direct variability of REE and TEE in kcal/d and the inverse in kcal/kg/d., Conclusions: as age increased, energy expenditure also increased. The estimated energy expenditure in kcal/cm/d did not differ with age and sex. The estimated energy expenditure, based on height, would be a practical and reliable method for estimating energy expenditure and ensuring adequate nutritional status.

This study demonstrated the relationship of low bone mineral density (BMD) with the degree of motor impairment, method of feeding, anthropometric indicators, and malnutrition in children with quadriplegic cerebral palsy (CP). The control of these factors could optimize adequate bone mineralization, avoid the risk of osteoporosis, and would improve the quality of life., Purpose: The purpose of the study is to explore the relationship between low BMD and nutritional status in children with quadriplegic CP., Methodology: A cross-sectional analytical study included 59 participants aged 6 to 18 years with quadriplegic CP. Weight and height were obtained with alternative measurements, and weight/age, height/age, and BMI/age indexes were estimated. The BMD measurement obtained from the lumbar spine was expressed in grams per square centimeter and Z score (Z). Unpaired Student's t tests, chi-square tests, odds ratios, Pearson's correlations, and linear regressions were performed., Results: The mean of BMD Z score was lower in adolescents than in school-aged children (p = 0.002). Patients with low BMD were at the most affected levels of the Gross Motor Function Classification System (GMFCS). Participants at level V of the GMFCS were more likely to have low BMD than levels III and IV [odds ratio (OR) = 5.8 (confidence interval [CI] 95% 1.4, 24.8), p = 0.010]. There was a higher probability of low BMD in tube-feeding patients [OR = 8.6 (CI 95% 1.0, 73.4), p = 0.023]. The probability of low BMD was higher in malnourished children with weight/age and BMI indices [OR = 11.4 (1.3, 94), p = 0.009] and [OR = 9.4 (CI 95% 1.1, 79.7), p = 0.017], respectively., Conclusion: There was a significant relationship between low BMD, degree of motor impairment, method of feeding, and malnutrition. Optimizing these factors could reduce the risk of osteopenia and osteoporosis and attain a significant improvement of quality of life in children with quadriplegic CP.

Objective: the purpose was to evaluate the nutritional status in hospitalized children according to their socio-demographic variables, underlying pathology and based on hospital length of stay., Methods: seven-hundred and sixty-three hospitalized patients of the Civil Hospital of Guadalajara Dr. Juan I. Menchaca were included in a cross-sectional study. The following anthropometric indices were taken: weight/length, weight/height, weight/age, length/age, height/age, head circumference/age and BMI/age. Data of socio-demographic variables and underlying pathology were also obtained. Student's t-test, Chi-squared test, ANOVA with post-hoc tests and logistic regression were used to identify the likelihood of risk of malnutrition., Results: subjects were divided according to their hospital length of stay in lower than seven days and seven days or more. At the time of admission, children with stay of seven days or more showed a greater deficit in the height/age index (OR = 1.77 [95% CI 1.16-2.7], p = 0.007), head circumference (OR = 2.68 [95% CI 1.5-4.7], p ≤ 0.001) and BMI (OR = 2.9 [95% CI 1.9-4.4], p ≤ 0.001). Males had higher risk of moderate/severe malnutrition (OR = 1.87 [95% CI 1.22-2.85], p = 0.003) and higher deficit in head circumference (OR = 1.89 [95% CI 1.06-3.37], p = 0.029). Infants with gastrointestinal and respiratory problems had higher frequency of malnutrition at the time of admission than did those with other pathologies (p < 0.001)., Conclusion: the pathological disease at time of admission and longer hospital length of stay increased the likelihood of malnutrition in male infants and preschool-aged children. There were demographic and educational risk factors in the home environment that could influence acute and chronic malnutrition.

Objective: The level of agreement between two blood pressure (BP) reading methods, auscultatory vs oscillometric, was examined using a mercury sphygmomanometer and an electronic device in children and adolescents with different levels of obesity. The readings were compared to determine their impact on the diagnosis of pre-hypertension/hypertension., Methods: Blood pressure readings were taken in children with obesity (body mass index ≥ 95th percentile) and severe obesity (≥120% 95th percentile). Bland-Altman analysis and Intraclass Correlation Coefficient were used to determine the agreement between measurements., Results: The mercury sphygmomanometer readings were lower than those obtained with the electronic device for both systolic and diastolic BP (P=.01 and P=.001, respectively). The mean systolic and diastolic BP differences between the oscillometric vs first mercury reading were 4.2/10.2mmHg, respectively. A large difference was observed between the BP measurement methods. The ICC showed regular to moderate reliability for the systolic BP (.595), but poor for the diastolic BP (.330). Screening using the first of three mercury measurements showed that 10.4% of the children and adolescents had BPs within the pre-hypertension/hypertension range. This was reduced to 5.2% when the mean of three mercury readings was used., Conclusions: Large discrepancies were observed in both the systolic and diastolic BP. These differences are not clinically acceptable as to consider the two instruments interchangeable. The electronic device readings were higher, and they overestimated the diagnosis of hypertension., (Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez.

Background: Nutrition transition provokes changes in the nutritional status of individuals subjected to the interaction of various environmental factors; therefore, the aim was to demonstrate that nutrition transition is associated with socioeconomic changes, eating habits and physical activity, potentially involved in stunting, overweight and obesity of schoolchildren., Methods: Case-control study. 102 participants from the Instituto Alteño para el Desarrollo de Jalisco (cases) and 194 from the elementary school system (controls), aged 5 to 12 years, were included. Dependent variables were these indexes weight/age (Z), height/age (Z), BMI (Z). Independent variables were the socioeconomic and demographic characteristics. Student's t test, chi square, odds ratio (OR) and 95% confidence intervals (95% CI) were estimated., Results: Family income was low (p = 0.031) and unstable job was higher in cases: OR = 4.1, 95% CI = 2.8-6.0. The frequency of stunting was higher in cases (9.9% vs. 5.9%). The combination of overweight/obesity was higher in controls (27.3% vs. 16.8%), OR = 1.85, 95% CI = 1.0-3.4., Conclusions: The nutritional status of children of Arandas, Jalisco, has been modified by an accelerate nutrition transition, provoked by socioeconomic, educational and demographic factors that might have influence on the persistence of stunting and an increasing prevalence of overweight/obesity.

Background: In 2015, Mexico was the top country for childhood obesity. The objective was to identify the association between physical activity and sedentary lifestyle with the social and demographic characteristics of families of schoolchildren in Arandas, Jalisco, Mexico., Methods: In a cross-sectional study, 192 schoolchildren were randomly selected. Body mass index (BMI), active and sedentary behaviors, and socio-demographic characteristics of families were obtained. Logistic regression models with the included variables were constructed., Results: Males living in not-crowding houses [OR 6.12 (2.17-17.25), p = 0.001], whose mothers were housewives [OR 2.44 (1.00, 5.94), p = 0.05], practiced more physical activity. Active transport to school was more common in schoolchildren whose fathers had lower income [OR 3.13 (1.27, 7.7), p = 0.013] and employment as peasant or mason [OR 5.12 (1.13, 23.3), p = 0.034]. Schoolchildren of nuclear families spent more hours watching television [OR 2.69 (1.10, 6.58), p = 0.03]. The frequency of outdoor playing was higher in males whose fathers had unstable employment [OR 2.93 (1.06, 8.1), p = 0.038] and low education [OR 2.94 (0.96, 8.98), p = 0.059]., Conclusion: Families with lower socioeconomic strata (less educated parents, unstable employment and family overcrowding) are more associated with active activities that do not require active economic spending.

Objective(s): This study aimed to demonstrate that dietary intake, anthropometric indicators, and body composition in children with end-stage kidney disease differs between those on peritoneal dialysis (PD) and those on hemodialysis (HD)., Methods: This was a cross-sectional and consecutive study that included 55 children and adolescents with end-stage kidney disease who were undergoing replacement therapy (22 PD patients and 33 HD patients). Two 24-hour dietary recall surveys were conducted for each patient. Anthropometric, biochemical, and body composition indicators were estimated. A Student's t-test and a Mann-Whitney U test were used for the parametric variables, whereas association tests were estimated for the nonparametric variables (i.e., χ 2 , Fisher exact test, and odds ratio). Regression models were designed to predict dietary intake on anthropometric and body composition indicators., Results: The mid-upper arm circumference was greater on the patients undergoing HD than on the PD patients (odds ratio = 15.8 [95% confidence interval (CI): 2.9, 85.1], P < .001); the arm muscular area was greater in the HD patients than in the PD patients (P = .07). Children on PD had significantly greater creatinine concentration (8.4 ± 3.0 mg/dL vs. 4.6 ± 1.2 mg/dL, P < .001), urea (101 ± 27 mg/dL vs. 50 ± 17 mg/dL, P < .001), and glucose (87 ± 14.4 mg/dL vs. 77 ± 10.2 mg/dL, P = .003). Children on PD had lower lipid intake (31.2 ± 15.8 vs. 40.9 ± 19.1 g/day, P = .032), lower percentage of adequacy of vitamin C (128 ± 66 vs. 146 ± 70, P = .046), and lower sodium (62 ± 43 vs. 79 ± 42, P = .044) than children on HD. Dietary intake predicted 40% to 80% of the variability in the nutritional status in children on PD and 28% to 60% in children on HD., Conclusions: Nutritional status is affected in most patients on dialysis treatment, which differs significantly among those who are undergoing PD or HD., (Copyright © 2017 National Kidney Foundation, Inc.

Aim: The study aimed to demonstrate that the assessment of the anthropomorphic measurements of children with cerebral palsy (CP) varies according to the type of motor dysfunction and references standard used for comparison., Method: In a cross-sectional design, 108 children 2 to 16 years were classified according to the type of motor dysfunction by gender and age group. Weight, mid-upper-arm-circumference (MUAC), and alternative measures for height were performed. Height/age and weight/age indexes and BMI were evaluated with percentiles and/or Z-scores with reference to a number of previously published references of growth, including those of the World Health Organization (WHO)., Results: Fifty-three (49.1%) were females and 55 (50.9%) males. Spastic type was predominant (73.1%) and 26.9% were other types of dysfunction. Most of the children were located on level IV (14.6%) and level V (73.1%) of the Gross Motor Function Classification System (GMFCS). Significant differences were found, suggesting that weight (p = 0.002), height (p = 0.001), and MUAC (p = 0.05) are higher in the spastic group than in other groups., Conclusions: The anthropometric indicators were significantly higher in the spastic group than in other groups. Upper-arm length (UAL) seemed less appropriate than knee height (KH) and lower-leg length (LLL) for measuring height. The WHO reference standard was not useful to evaluate the majority of anthropometric indexes in children with CP, other references as the growth charts of Day and Brooks have been more suitable.

Objective: The study aimed to demonstrate that the duration of hospitalization has a significant effect on the nutritional status of children treated in a university hospital., Methods: A longitudinal study was conducted during 2014, with a non-random sampling site concentration in children from birth to 19 years who were admitted to the hospital in the past 24 hours and who met the inclusion criteria and had signed informed consent. Upon entering, at 7 days, and at discharge, anthropometric indices, including weight/age, height/age, weight/height, BMI/age, head circumference/age, triceps and subscapular skin folds, and fat percentage, were obtained. Student's t-test, U Mann-Whitney, ANOVA, chi square, Wilcoxon, and odds ratios were used to analyze the data., Results: In total, 206 patients were included: 40% infants, 25% preschoolers, 15% schoolchildren, and 20% teenagers. Infants had a significant improvement from admission to discharge in the indices weight/length (p = 0.042) and BMI (p = 0.002); adolescents showed decreased BMI from admission to discharge from the hospital (p = 0.05). Patients with longer hospitalization (more than 10 days) had an increased deficit in anthropometric indices at admission (p < 0.05). Infants had a higher risk of deficit in the BMI index and height/age than preschoolers, schoolchildren, and adolescents between admission and discharge., Conclusion: When the nutritional condition of a child was critical at admission, the child remained hospitalized significantly longer. Infants come under the age group most vulnerable to malnutrition and require greater monitoring of nutritional status during hospitalization.

Background: The prevalence of overweight and obesity in children in Mexico are high, as well as the complications associated with their presence. The objective of this work was to estimate the prevalence of metabolic syndrome in obese children and adolescents attending a Hospital Clinic and identify the associated factors., Methods: Cross sectional design with 120 children and adolescents; of either sex, with exogenous obesity and BMI > 2.0 standard deviations. Personal and family history was collected, blood pressure was measured and determination of serum glucose, insulin, lipoprotein HDL cholesterol and triglycerides were performed. The presence of metabolic syndrome with the ATPIII, WHO and International Diabetes Federation criteria was identified. The association of metabolic syndrome with different variables was identified with chi square test and calculation of odds ratio., Results: Mean age was 10.6 ± 2.7 years. The prevalence of metabolic syndrome was 37.5% to 54.5% depending on the criteria used. The presence of metabolic syndrome was associated with a history of large birth weight (OR= 2.21 [1.01-4.82]), and insulin resistance (OR= 6.53 [2.40-18.2])., Conclusions: The prevalence of metabolic syndrome is high in this group of children and adolescents with obesity. The history of large birth weight and the presence of insulin resistance should alert us to the presence of the disease.

A proper nutrition during the first two years of life is critical to reach the full potential of every human being; now, this period is recognized as a critical window for promoting optimal growth, development, and good health. Therefore, adequate feeding at this stage of life has an impact on health, nutritional status, growth and development of children; not only in the short term, but in the medium and long term. This paper provides recommendations on complementary feeding (CF) presented as questions or statements that are important for those who take care for children during this stage of life. For example: When to start complementary feedings: 4 or 6 months of age?; Exposure to potentially allergenic foods; Introduction of sweetened beverages; Use of artificial sweeteners and light products; Food introduction sequence; Food consistency changes according to neurological maturation; Number of days to test acceptance and tolerance to new foods; Amounts for each meal; Inadequate complementary feeding practices; Myths and realities of complementary feeding; Developmental milestones; Practice of "Baby Led Weaning" and practice of vegetarianism., (Copyright © 2016 Hospital Infantil de México Federico Gómez.

Objetivo: identificar los hábitos alimentarios de adolescentes embarazadas en cuatro estados civiles diferentes: casada, cohabita con una pareja, soltera sin pareja y soltera con una pareja. Métodos: en estudio transversal, se incluyeron 321 adolescentes embarazadas de 13-19 años que acudieron al Hospital Civil de Guadalajara Dr. Juan I Menchaca, Guadalajara (Jalisco, México). Se encontraban sanas, en cualquier trimestre del embarazo y pertenecían a un nivel socioe-conómico bajo o medio-bajo. El estado civil se estratificó en: casadas; en unión libre; soltera con una pareja y soltera sin pareja. Se incluyeron datos socio-demográficos, económicos y de hábitos de alimentación. Se utilizaron pruebas de ANOVA, pruebas post-hoc para Chi 2 , razón de momios y modelos de regresión logística. Resultados: la frecuencia de las adolescentes casadas fue de 9,3%, 59,8% en unión libre, 15,3% eran solteras sin pareja y 15,6% solteras con pareja. La baja escolaridad (RM 2,6 [1,5-4,4]) y la ocupación en el hogar (RM 4,47 [1,99-10,0]) predominaron entre las adolescentes en unión libre; la ocupación en el hogar (RM 0,28 [0,127-0,61]) y cenar sin compañía (RM 4,12 [1,62-10,8]) fueron significativamente más frecuentes en adolescentes sin pareja. El consumo de verduras fue menor en las adolescentes casadas y en quienes cohabitaban con pareja; el consumo de frijoles y pan dulce fue menor en adolescentes embarazadas casadas. Conclusión: debido a que ciertas variables y hábitos de alimentación mostraron diferencias entre los grupos es pertinente analizar las adolescentes embarazadas de acuerdo a su estado civil.

Objective: to identify the association between the percentage of adequacy of energy and protein and the distribution of macronutrients and sugar in the diets of mothers and schoolchildren with their respective BMI., Methods: in a cross-sectional study, 174 5-12-year-old schoolchildren and their mothers were randomly selected. BMI was measured, and 24-hour dietary surveys were administered on weekdays and weekends. The associations between the dietetic indicators in the mothers and their children and the BMI of the mothers and their children were assessed. The chi-square test, linear regression and odds ratio were used for analysis., Results: excessive energy consumption in the mothers increased the risk of excessive energy consumption in their daughters by 11-fold (p=0.04). Maternal lipid intake was associated with the consumption of lipids in their sons and daughters (p., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

Since the early 1990s we noted that family dysfunction was more common in children with severe primary malnutrition than in children admitted to the hospital without malnutrition. Defects on feeding habits during the first year of life, especially early weaning and inadequate complementary feeding were more common in dysfunctional families. We also observed that chronic malnutrition in preschool children, and overweight and obesity in schoolchildren were more common in children from dysfunctional families. Once the association between dysfunctional family dynamics and obesity in schoolchildren was demonstrated, it was observed that low education of fathers and mothers increased twofold the possibility of family dysfunction: OR: 2.06; 95% CI: 1.37-3.10 and OR: 2.47; 95% CI: 1.57-3.89, respectively. In addition, the low-income and the lower purchasing power of foods were associated to family dysfunction (p<0.05). A remaining task is to explore how to assess family dysfunction in composite, extended, single-parent families where there exist other persons vulnerable to the different entities of malnutrition syndrome and indeed depend on adults for their care, food and nutrition.
