SUMMARY:

Introduction: Overweight/obesity is caused by a combination of several factors including exposure to an environment that promotes weight gain, inadequate behavioral and biological responses to this exposure, and sociocultural and economic factors. Objective: To evaluate the association between dietary patterns, disordered eating behaviors, body image, food security, and overweight/obesity in adolescents. Methods: This thesis is structured in a multipaper format. This was a cross-sectional study carried out with adolescents of both sexes, aged between 11 and 17 years, and enrolled in the state public school system in the city of Salvador/BA, Brazil. A probabilistic sampling process was used, and the selection of schools was carried out using a cluster sampling procedure in two stages: schools and classrooms. The sample size was 1,215 participants. Nutritional status was determined using the body mass index. A semi-quantitative food frequency questionnaire was used to identify dietary pattern, and latent class analysis was subsequently performed. To verify the presence of bulimia behaviors, the Bulimic Investigation Test of Edinburgh and Body Shape Questionnaire were used to identify body dissatisfaction. Household food security was verified using the Brazilian Food Insecurity Scale. Multinomial logistic regression and 95% confidence intervals were used to evaluate the association between sociodemographic characteristics, food security, and dietary patterns. The association between dietary patterns and overweight/obesity was assessed using Poisson multiple regression analysis with robust variance. We also evaluated the association between disordered eating behaviors, body dissatisfaction, and overweight/obesity in adolescents according to the household food security situation. Results: Three manuscripts were developed. The first identified four dietary patterns called “Mixed,” “Low consumption,” “Prudent” and “Diverse.” The “Diverse” dietary pattern was associated with the lowest economic stratum (OR:2.02; CI:1.26 – 3.24). There was no association between food insecurity and identified dietary patterns. The results of the second manuscript indicated that the prevalence of overweight/obesity was 15.4%. The greatest adherence was to the “Low consumption” and “Prudent” dietary patterns, both in the general sample and among the overweight/obese adolescents. A positive association was found between the “Low consumption” pattern (PR:1.53; CI:1.01–2.32), when compared to the “Mixed” pattern and overweight/obesity among adolescents. The third manuscript pointed out that, in households with food security, associations were identified between negative eating attitudes (PR:1.83; CI:1.06 – 3.15), body dissatisfaction (PR:4.81; CI:3.09–7.47), and overweight/obesity. Among adolescents with household food insecurity, bulimia behaviors (PR:3.46; CI:2.24 – 5.34) and body dissatisfaction (PR:3.81; CI:2.53–5.75) were associated with a more significant occurrence of overweight/obesity. Conclusions: Understanding the relationships involved in the development of overweight/obesity and the role that food (in)security plays is fundamental to providing comprehensive health care and assisting in developing public policies for adolescents. Thus, it is expected to contribute to the promotion of healthy eating for this age group at all socioeconomic levels, especially the lowest.
