SUMMARY:

Obesity is one of the health problems that grows the most throughout the world during adolescence, being a disease that is difficult to control, with multifactorial etiology. Understanding the social determinants and environmental conditions that lead to overweight and obesity in adolescence is essential for developing strategies for their control and treatment. Objective: To evaluate the factors associated with overweight and obesity in adolescents, considering Social Network Analysis. Methods: This thesis was developed through two studies: 1) a cross-sectional study with adolescents in a rural school in Rio Grande do Norte - RN; 2) a systematic review to evaluate the influence of social networks on food consumption habits and physical activity practices and their relationship with overweight and obesity in adolescents aged 12 to 19 years. For the cross-sectional study, n = 90 students from a rural school in Ielmo Marinho participated and answered questionnaires about sociodemographic characteristics, food consumption, physical activity, and social networks. Social networks were built based on students’ social ties. Principal Component Analysis was performed to determine dietary patterns and logistic models to investigate variables associated with overweight/obesity. The systematic review was registered in PROSPERO and followed the PRISMA guidelines. Searches were carried out in PubMed, Scopus, EMBASE, PsycINFO, and Web of Science databases for publications from 2009 to 2022. To evaluate the methodological quality of the studies found, the Newcastle-Ottawa scale was used. Results: The results of the cross-sectional study showed that the majority of participants were girls (62.9%) and the proportion of overweight/obesity was 30% among adolescents. The students cited 2,070 people from their networks (family, friends at school, friends outside of school, and others). Among them, the family had the greatest degree of influence (61%) in the network and shared more meals with teenagers (47%). Adolescents' perception of the body size of their family members with obesity, compared to normal weight or underweight, was prevalent (51%). Adolescents with unhealthy eating patterns were 72% more likely to be classified as overweight/obese, and eigenvector centrality was also associated with overweight/obesity. For the systematic review, after screening, 7 studies were identified and carried out in countries in Europe, North America, the Chinese Republic, and the Oceanic continent. The age of the participants ranged from 12 to 18 years old, with females being the most prevalent. Of the studies found, 3 were cross-sectional, 3 longitudinal, and 1 cohort. Three studies found evidence that adolescents' weight was influenced by their friendship ties and that friends at school can influence their BMI and physical activity. These 3 studies also showed that in the friendship networks of adolescents of both sexes, behaviors related to obesity are similar in some leisure activities and eating habits. Conclusion: This study showed the need to understand the different social networks shared by adolescents, as these are associated with their behaviors and habits, especially those closest to them, such as family and friends. There is also a need for greater depth to understand the influences that the structure and function of social networks have on health behaviors among adolescents who participate in different types of networks (family, school friends, friends outside of school, among others).
