Living with parents, lifestyle pattern and common mental disorders in adolescents: a school-based study in Brazil.

BACKGROUND: Mental health conditions represent 16% of the global burden of disease and injury in adolescents. Promotion, protection, and restoring the mental health must be considered indispensable, especially in adolescence. This study aims to verify the association of lifestyle pattern, living with parents and the presence of Common Mental Disorders (CMD) in Brazilian adolescents. METHODS: Cross-sectional study that analyzed data from 71,553 adolescents aged 12-17 years, from the Study on Cardiovascular Risks in Adolescents (ERICA), between 2013 and 2014. Principal Component Analysis (PCA) was performed to identify lifestyle pattern, and Logistic Regression Models were performed to identify the associations between lifestyle pattern, living with parents, and presence of CMD. RESULTS: To construct the Common Mental Disorders (CMD) variable, the Goldberg General Health Questionnaire was used. The Pattern of Healthy Lifestyle Practices found was characterized by higher water consumption, lower consumption of ultra-processed foods, the habit of eating breakfast, less exposure time to screens, habit of physical activity, and longer mean sleep time in hours. Adolescents belonging to the second (OR: 0.73; 95% CI 0.65-0.82) and third (OR: 0.44; 95% CI 0.39-0.50) terciles of the pattern, that is, those who had higher belonging to the pattern had lower chances of having CMD. Adolescents who lived with neither parent (OR: 1.44; 95% CI 1.16-1.78) were associated with a higher chance to present CMD. CONCLUSION: Living with parents can contribute to better mental health among adolescents. In addition, the adoption of a healthy lifestyle, encouraged by parents and the community, can reduce the chances of CMD in Brazilian adolescents.

School environment and obesity in adolescents from a Brazilian metropolis: cross-sectional study.

BACKGROUND: Childhood-juvenile obesity is a globally acknowledged public health issue. The school environment has been widely assessed because it is where adolescents stay longer during the day, and it may have impact on obesity. School became a crucial environment for obesity prevention in children and adolescents. The aim of the present study was to associate schools' internal environment factors and its surrounding areas with obesity in adolescents from a Brazilian metropolis. METHODS: Cross-sectional study based on data from the Study on Cardiovascular Risk in Adolescents. The sample comprised 2,530 adolescents in the age group 12-17 years, who were enrolled in public and private schools in Belo Horizonte City, Brazil. Obesity was the dependent variable based on the cut-off point score-z + 2 for body mass index based on age. School environment's independent variables were 'managerial dependence type', 'number of drinking fountains', 'school sports environment' and 'ready-to-eat food shops' around the school (within an 800 m buffer). RESULTS: Obesity prevailed in 7.21% in sample. The largest number of drinking fountains decrease by 9% the chances of obesity in adolescents enrolled in public and private schools; however, the second and third terciles recorded for the number of ready-to-eat food shops within the 800 m buffer around schools increased by 24% and 44% the chances of obesity, respectively. CONCLUSION: School food environment aspects such as the number of operational drinking fountains and the availability of ready-to-eat food shops around the school were associated with obesity in adolescents from a Brazilian metropolis.

Characteristics of the School Food Environment Affect the Consumption of Sugar-Sweetened Beverages Among Adolescents.

Sugar-sweetened beverages are widely available and accessible in school environment, and their presence and characteristics of this environment can influence their consumption. This study examines the association of drinking fountains per 100 students, soft drink sales, soft drink advertising, and the presence of street vendors and sugar-sweetened beverages consumption among adolescents in Brazil. This cross-sectional study was carried out using data from the Study of Cardiovascular Risk in Adolescents that was conducted between March 2013 and December 2014. The sample comprised 71,475 adolescents aged 12-17 years from 1,247 public and private schools in Brazilian cities. Sugar-sweetened beverages consumption was the dependent variable. The main effect was the school food environment, which was evaluated based on drinking fountains per 100 students, soft drink sales, soft drink advertising, and the presence of street vendors. Public and private schools that sold soft drinks were associated with higher average sugar-sweetened beverages consumption among adolescents. Our study highlights the importance of creating healthy school food environments by banning sugar-sweetened beverages in schools accordingly.
