Nogueira LR. Excess body weight, consumption of fruits and vegetables by adolescents and local food environment in São Paulo [dissertation]. Sao Paulo: School of Public Health, USP; 2018. Introduction: An obesogenic environment can be defined as "the sum of influences, opportunities or conditions that the environment has in the promotion of obesity", where the consumption of risky foods is stimulated to the detriment of protective foods consumption. Currently, overweight presents as a public health problem, and inadequate diet is a modifiable factor for its development. Fruits and vegetables play a key role in the prevention of overweight, since they have low energetic density, are sources of vegetable proteins and micronutrients considered protective, besides being rich in fibers, increasing the feeling of satiety. Objective: To investigate the association between overweight, fruit and vegetable consumption by adolescents and the local food environment in São Paulo. Methods: Data from the 2015 Health Survey of São Paulo were used, which is a cross-sectional population-based study with probabilistic sampling of residents in permanent households in the municipality. Data were collected through a structured questionnaire and two 24h dietary recall. The nutritional status was evaluated by the Body Mass Index classified as non-overweight (percentile <85) and overweight (percentile ≥85) according to the World Health Organization. Food environment data were obtained from the Municipal Register Sanitary Surveillance and the Municipal Department of Labor and Entrepreneurship. Buffers (areas of influence) of 500, 1000 and 1500 meters were created to evaluate the presence of establishments around the adolescent's residences participating in the study. To verify the association between food environment, consumption of fruits and vegetables and overweight, multilevel logistic regression models were developed, adjusted by potential cofounders. Data analysis was performed in Stata 13.0 program, considering a significance level of 5%. Results: The adolescents presented low consumption of fruits and vegetables, since only 6.1% consumed the amount recommended by the World Health Organization. In addition, 29.6% were overweight. Most of the adolescents had markets, supermarkets and grocery stores (85.5%), restaurants (75.6%), and street markets and fruit and vegetable stands (50.6%) around the residence but did not present fast-food restaurants (93,9%), bakeries and coffee shops (89.5%), and pizzerias (76.8%). The presence of a street market in the area closest to the households (500 m) and higher family income was associated with higher consumption of fruits and vegetables. The presence of fast-food restaurants in the 500 meters buffer around the residence was positively associated with being overweight. Conclusion: These results suggest that the food environment in São Paulo may be an important factor in relation to food consumption and, consequently, to overweight in adolescents in the city. Thus, it is necessary to intensify p...
