Amongst overweight/obese adolescents, those with slight and moderate body image dissatisfaction were less likely to follow a Western-like dietary pattern when compared with those satisfied with their body image. Additionally, in this group, adolescents with high body image dissatisfaction was more likely to follow a restrictive pattern.

This study demonstrated that the HTW phenotype was associated with an atherogenic lipid profile, and this phenotype is suggested as a screening tool to identify adolescents with metabolic alterations.

There is a significant increase in overweight and obesity in adolescents worldwide. Here, we performed a cross-sectional study to examine the potential association between food consumption profiles and overweight in a large number of adolescents from Brazil. Sampling by clusters and conglomerates was carried out in students of public schools in Salvador, Brazil, between June and December 2009 and 1496 adolescents were evaluated. Data on socio-epidemiological data, anthropometric status and food consumption were captured. Multivariate analyses, such as hierarchical clustering and correlation networks, were used to perform a detailed description of food consumption profiles. There were differences in age and anthropometric status related to sex. Four clusters of food groups were identified based on the intake profile in the study population. No disparities in food intake were observed in individuals stratified by sex or anthropometric status. Furthermore, network analysis revealed that overweight or obesity were hallmarked by a selectivity in the ingestion of food groups that resulted in the appearance of inverse correlations of consumption, which was not present in eutrophic adolescents. Thus, overweight and obesity are associated with preferential choices of ingestion of specific food groups, which result in the appearance of inverse correlations of consumption. Such knowledge may serve as basis for future targeted nutritional interventions in adolescents.

Context Zinc is an essential trace mineral required for the function of brain and neural structures. The role of zinc supplementation in the prevention and treatment of depression has been suggested in clinical studies that reported a reduction in depressive symptoms. Objective The aim of this review was to determine whether zinc supplementation vs placebo can prevent or improve depressive symptoms in children, adolescents, or adults. Data Sources Five electronic databases were searched, and studies published until September 2019 were included without language restriction. Study Selection Randomized, controlled, crossover trials that evaluated the effect of zinc supplementation vs a comparator for prevention or improvement of depressive symptoms in children, adolescents, or adults were eligible for inclusion. Data Extraction Two authors independently performed data extraction and risk-of-bias assessment. Results The initial search identified 12 322 studies, 5 of which were eligible for meta-analysis. The standardized mean difference (SMD) showed an average reduction of 0.36 point (95%CI, −0.67 to −0.04) in the intervention group compared with the placebo group. Forstudies in which the mean age of participants was ≥ 40 years, the SMD was reduced by 0.61 point (95%CI, −1.12 to −0.09) in the intervention group vs the placebo group. The meta-analysis by sample size (< 60 individuals and  ≥ 60 individuals) did not show an effect of zinc supplementation in reducing depressive symptoms (SMD −0.28; 95%CI, −0.67 to −0.10; and SMD −0.52; 95%CI, −1.10 to 0.06). Conclusion Zinc supplementation may reduce depressive symptoms in individuals treated with antidepressant drugs for clinical depression. Systematic Review Registration PROSPERO registration number CRD42018081691.

The results of this study suggest that among adolescents, overweight, body image dissatisfaction, and restrictive diet are important risk factors to adoption of extreme weight-control behaviors.

Objective: To assess the association between physical intimate partner violence and household food security within households with schoolchildren. Design: Cross-sectional study. Setting: Salvador, Bahia, north-eastern Brazil. Subjects: The study was conducted in 1019 households with students. Violence between couples was evaluated using the Portuguese version of the revised Conflict Tactics Scales (CTS2), previously adapted and validated for use in Brazil. The Brazilian Food Insecurity Scale (BFIS) was used to identify food insecurity. We also obtained socio-economic information for each participant. We used multivariate Poisson regression to assess the associations of interest. Results: According to the results of the BFIS, 62·5 % of the households were found to experience food insecurity, including 19·5 % moderate food insecurity and 6·5 % severe food insecurity. The prevalence of minor physical violence was 9·6 % (95 % CI 7·8, 11·4 %) and of severe physical violence was 4·7 % (95 % CI 3·4, 6·0 %) among the couples. In the final multivariate model, it was found that couples reporting minor (prevalence ratio = 1·23; 95 % CI 1·12, 1·35) and severe (prevalence ratio = 1·16; 95 % CI 1·00, 1·34) physical violence were more likely to be experiencing household food insecurity, compared with those not reporting physical violence. Conclusions: Physical intimate partner violence was associated with food insecurity of households. The present study brings new data to the subject of the role of violence in the context of food insecurity.
