RESUMO

OBJECTIVE: To investigate the association of mental health in childhood and adolescence with four outcomes at 18 years: ultra-processed food (UPF) consumption, body mass index (BMI), excessive weight (EW), and body composition, including fat mass (FM) and fat free mass (FFM) in kg, FM index (FMI) and FFM index (FFMI) in kg/m2. METHODS: Cohort study in which The Development and Well-Being Assessment (DAWBA) (6 and 11 years) and the MINI International Neuropsychiatric Interview (MINI) (18 years) provided information on internalizing (INT), externalizing (EXT) and any mental disorder (ANY). The exposure was classified in: "never", "at 6 and/or 11 years", "at 18 years only" and "at 6, 11, and 18 years". Linear and logistic regression were run. All analyses were stratified by sex. RESULTS: A total of 2722 participants were analyzed. At 18 years, female with EXT disorders at 6 and/or 11 years presented higher BMI (ß: 1.70; 0.18-3.23), FM (ß: 4.74; 1.42-8.06), and FMI (ß: 1.53; 0.28-2.79) than those who never had. The odds of EW at 18 years was also higher in females with EXT disorders at 6 and/or 11 years (OR: 3.39; 1.56-7.36) and at the three time points (OR: 7.08; 1.69-29.59). Males with EXT disorders at 6 and/or 11 years presented higher FM (ß: 4.45; 1.85-7.06) and FMI (ß: 1.47; 0.63-2.31). CONCLUSIONS: Among children and adolescents showing symptoms of EXT disorders, weight should be monitored carefully, thus ultimately contributing to reduce the burden of EW in adolescence.

RESUMO

La obesidad en la infancia y adolescencia es un problema de salud mundial que ha ido en aumento, esto es preocupante no sólo por el riesgo de comorbilidades cardiovasculares, sino que también las psicosociales. La cirugía bariátrica se ha convertido en una alternativa para los casos de obesidad severa en adolescentes. Se trata de un método invasivo que requiere evaluación cuidadosa, no sólo en el aspecto físico, sino que también en el psicológico y social. El objetivo de este trabajo es conocer la evidencia disponible sobre las consecuencias que conlleva la cirugía bariátrica en adolescentes. Se realizó una búsqueda en la literatura en base de datos como PubMed, ScienceDirect y Scopus, utilizando palabras clave como "cirugía bariátrica", "obesidad en adolescentes", "efectos psicosociales" y "salud mental". Se han identificado diversos efectos negativos, entre los cuales destacan las deficiencias nutricionales que afectan al sistema nervioso central, los impactos en la salud mental y el riesgo de psicopatología. Sin embargo, la mayor cantidad de información e investigación se centra en los efectos positivos de la cirugía bariátrica. Aún faltan estudios en población adolescente, especialmente de carácter prospectivo y documentación de los posibles efectos negativos en la salud.

Obesity in childhood and adolescence is a global health problem that has been on the rise, and it is highly concerning due to the risk of cardiovascular and psychosocial comorbidities. Bariatric surgery has become an alternative for cases of severe obesity in adolescents. It is an invasive method that requires careful evaluation, not only in the physical aspect but also in the psychological and social aspects. The aim of this study is to understand the available evidence regarding the consequences of bariatric surgery in adolescents. A literature search was conducted in databases such as PubMed, ScienceDirect, and Scopus, using keywords such as "bariatric surgery," "obesity in adolescents", "psychosocial effects," and "mental health." Among the negative effects found, complications related to nutritional deficiencies affecting the central nervous system, effects on mental health, and the risk of psychopathology are evident. However, most of the information and research focus on the positive effects of bariatric surgery. There is a lack of studies in the adolescent population, especially those of a prospective nature, and documentation of potential negative health effects.

RESUMO

OBJECTIVES: To examine if intergenerational transmission of parent weight talk occurs, the contextual factors prompting weight talk, and whether parent weight talk is associated with child weight, dietary intake, psychosocial outcomes, and food parenting practices. STUDY DESIGN: Children aged 5-9 years and their families (n = 1307) from 6 racial and ethnic groups (African-American, Hispanic, Hmong, Native American, Somali/Ethiopian, White) were recruited for a longitudinal cohort study through primary care clinics in Minneapolis/St. Paul, Minnesota from 2016 through 2019. Parents filled out surveys at 2 time points, 18 months apart. Adjusted regression models examined associations of interest. RESULTS: Intergenerational transmission of parent weight talk was observed. In addition, significant associations were found between parent engagement in weight talk and higher weight status and poorer psychosocial outcomes in children 18 months later. Parent engagement in weight talk was also associated with more restrictive food parenting practices 18 months later. CONCLUSIONS: Parents' exposure to weight talk as children increased the likelihood of engaging in weight talk with their own children and had harmful associations over time with parent restrictive feeding practices, child weight, and psychosocial wellbeing in children. Health care providers may want to consider both modeling positive health-focused conversations and educating parents about the potential harmful and long-lasting consequences of engaging in weight talk with their children.

RESUMO

Our objective was to systematically examine the characteristics of exercise interventions on adherence and dropout in children and adolescents with obesity. PubMed, Embase, PsycINFO, Lilacs, Scielo, and The Cochrane Central Register of Controlled Trials and reference lists of relevant articles were searched. We included randomized controlled trials with exercise interventions for pediatric patients with obesity presenting data on dropout and/or adherence. Two reviewers screened the records independently for eligibility with disagreements being resolved by a third reviewer. Twenty-seven studies with 1268 participants were included. Because of high heterogeneity and poor reporting of adherence, it was not possible to perform a meta-analysis. Dropout prevalence was calculated, and subgroup analyses comparing different types of exercise and a meta-regression with potential moderators were performed. We found a dropout rate of 13%. Subgroup analyses did not identify significant differences. The duration of the exercise presented a moderating effect on dropout, suggesting that longer exercise sessions may lead to higher dropout in children and adolescents with obesity. Because of the poor adherence data, it is not clear which exercise characteristics may moderate adherence. To improve the quality of childhood obesity care, it is mandatory that future studies present adherence data. Systematic review registration: PROSPERO CRD42021290700.

RESUMO

BACKGROUND: The rapid rise in obesity rates among school children in Latin America and the Caribbean (LAC) could have a direct impact on the region's physical and mental health, disability, and mortality. This review presents the available interventions likely to reduce, mitigate and/or prevent obesity among school children in LAC by modifying the food and built environments within and around schools. METHODS: Two independent reviewers searched five databases: MEDLINE, Web of Science, Cochrane Library, Scopus and Latin American and Caribbean Health Sciences Literature for peer-reviewed literature published from 1 January 2000 to September 2021; searching and screening prospective studies published in English, Spanish and Portuguese. This was followed by data extraction and quality assessment using the Cochrane risk-of-bias tool (RoB 2) and the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I), adopting also the PRISMA 2020 guidelines. Due to the heterogeneity of the intervention's characteristics and obesity-related measurements across studies, a narrative synthesis was conducted. RESULTS: A total of 1342 research papers were screened, and 9 studies were included; 4 in Mexico, and 1 each in Argentina, Brazil, Chile, Colombia, and Ecuador. Four studies reported strategies for modifying food provision; four other targeted the built environment, (modifying school premises and providing materials for physical activity); a final study included both food and built environment intervention components. Overall, two studies reported that the intervention was significantly associated with a lower increase over time in BMI/obesity in the intervention against the control group. The remaining studies were non-significant. CONCLUSIONS: Data suggest that school environmental interventions, complementing nutritional and physical education can contribute to reduce incremental childhood obesity trends. However, evidence of the extent to which food and built environment components factor into obesogenic environments, within and around school grounds is inconclusive. Insufficient data hindered any urban/rural comparisons. Further school environmental intervention studies to inform policies for preventing/reducing childhood obesity in LAC are needed.

RESUMO

Physical fitness is considered a protective factor for children's general health and has been related to enhanced cognitive functioning. However, it appears that cognition could be affected in children with overweight or obesity. The present study aimed to determine the relationship between physical fitness components and fluid intelligence in normal-weight and overweight/obese children. In this cross-sectional study, a total of 317 schoolchildren participated (165 boys, 52.05%), aged between six and 11 years old (1st to 5th grade), belonging to a public school in the south of Brazil. Psychologists evaluated fluid intelligence through the Raven's Colored Progressive Matrix Test. The physical fitness evaluation followed the procedures of the "Brazil Sports Project". Weight and height were measured to determine body mass index and generalized linear regression analyses were used with a 95% confidence interval. Our results showed that agility was inversely associated with fluid intelligence only in the overweight/obese group (ß = -1.506; p = 0.01). Cardiorespiratory and muscular fitness were not associated with fluid intelligence. In conclusion, agility was the only physical fitness component related to fluid intelligence, and this relationship was found exclusively in overweight/obese schoolchildren.

RESUMO

This study aimed to determine whether pupils who have breakfast just before a cognitive demand, do not regularly skip breakfast, and consume a high-quality breakfast present higher cognitive performance than those who do not; furthermore, to establish differences according to their nutritional status. In this study, 1181 Chilean adolescents aged 10-14 years participated. A global cognitive score was computed through eight tasks, and the body mass index z-score (BMIz) was calculated using a growth reference for school-aged adolescents. The characteristics of breakfast were self-reported. Analyses of covariance were performed to determine differences in cognitive performance according to BMIz groups adjusted to sex, peak height velocity, physical fitness global score, and their schools. A positive association was found in adolescents' cognitive performance when they had breakfast just before cognitive tasks, did not regularly skip breakfast, presented at least two breakfast quality components, and included dairy products. No significant differences were found between breakfast components, including cereal/bread and fruits/fruit juice. Finally, pupils who were overweight/obese who declared that they skipped breakfast regularly presented a lower cognitive performance than their normal-BMIz peers. These findings suggest that adolescents who have breakfast just prior to a cognitive demand and regularly have a high quality breakfast have better cognitive performance than those who do not. Educative nutritional strategies should be prioritized, especially in "breakfast skippers" adolescents living with overweight/obesity.

RESUMO

OBJECTIVE: To assess the relationship between obesity and select childhood flourishing markers including academic skills and coping strategies. STUDY DESIGN: Cross-sectional study utilizing parental reported data for children aged 10-17 years (n = 22 914) from the 2016 National Survey of Children's Health. Multiple binary regressions assessed the association between body mass index-for-age and 5 school-related and behavioral childhood flourishing markers independently and combined, including completing homework, showing interest in learning, finishing tasks, staying calm when challenged, and caring about academics. Analyses were adjusted for age, sex, depression, sleep, digital media exposure, poverty, and parental education level. RESULTS: Only 28.9% of children with obesity were reported to have all 5 markers, compared with 38% with overweight, and 40.5% with normal body mass index. In an adjusted model, children with obesity had significantly decreased odds of demonstrating 4 of 5 markers: showing interest in learning (aOR, 0.78; 95% CI, 0.62-0.97), finishing tasks (aOR, 0.77; 95% CI, 0.63-0.94), staying calm when challenged (aOR, 0.73; 95% CI, 0.59-0.90), and caring about academics (aOR, 0.69; 95% CI, 0.55-0.86). Completing homework was not associated with obesity. Youth with obesity also had 23% decreased odds (aOR, 0.77; 95% CI, 0.61-0.98) of meeting the combined measure for flourishing markers. CONCLUSIONS: Childhood obesity is associated with poor academic skills and coping strategies which may lead to worse individual and public health outcomes. Further studies are needed to create validated flourishing measures and identify interventions that promote healthy youth behavior and academic success.

RESUMO

BACKGROUND: A product package can be a powerful marketing tool to persuade and attract consumers at the point-of-sale. Evidence shows that most advertised products have low nutritional quality. Currently, Mexico has incorporated advertising regulations on food and beverage packaging. OBJECTIVES: To analyze the advertising strategies used to target children on packaging and to assess the nutritional quality of sugar-sweetened beverages available in the Mexican market. METHODS: Photographs of 2380 beverages available in retail stores in Mexico City from January to March 2017 were analyzed. Beverages were classified as displaying child-directed strategies or nondirected strategies. Nutrition quality was evaluated using the Pan American Health Organization nutrient profile model. RESULTS: The use of characters was the most frequent strategy among beverages with child-directed strategies (82.0%). The evaluation of nutrition quality found that 88.0% (P < .001) of sugar-sweetened beverages with child-directed strategies were excessive in free sugars and 56.9% (P < .001) contained other sweeteners. Beverages with more than two advertising strategies have the highest proportion of excessive free sugars (93.4%, 95% CI 82.8-98.6). CONCLUSIONS: The use of characters and other visual strategies were frequently used in the packaging of sugar-sweetened beverages with child-directed strategies. In addition, these beverages are excessive in free sugars and contain a large number of products with other sweeteners.
