SUMMARY:

Adolescence is a period of bodily changes, the formation of behaviors, and social interactions, which impact the eating patterns and nutritional status of individuals, with possible repercussions throughout life. Aiming to contribute to the process of surveillance and food and nutritional care of this public, the objective of this doctoral thesis was to investigate the prevalence of nutritional deviations, patterns, and eating behaviors of Brazilian adolescents and their associations with psychosocial, behavioral and sustainability factors. Ten studies were developed, one methodological and eight association, using a quantitative approach with data from sample 2 of the National School Health Survey (PeNSE) 2015, and one trial. (1) The methodological study highlights the potential of PeNSE databases in studies of food and nutrition surveillance (VAN). The association studies explore the following food and nutrition issues for adolescents: (2) adherence to school feeding, (3) food and nutritional profiles, (4) obesity and height deficit, (5) indicators of food sustainability; (6) risk behaviors for eating disorders, (7) distortion of body image, (8) experience of food insecurity and (9) dissatisfaction with body image. Finally, the essay discusses (10) food and nutritional care in adolescence. The dependent/main and independent/secondary variables of the association studies were representatives of individual, home, and school contexts. The identification of the explanatory models for each problem occurred with the application of descriptive statistics, Person's Chi-square test, Poisson Regression Analysis (classic or multilevel), or Correspondence Analysis. The main results were: (1) the PeNSE databases allow several association analyzes to explore food, nutritional and behavioral issues relevant to the Brazilian adolescents' VAN process; (2) the prevalence of low adherence to school meals (64.2%) was associated with individual behaviors, the family's socioeconomic position and the school context; (3) the most prevalent food and nutritional profile among adolescents was characterized by a dietary pattern with lower nutritional risk with eutrophy (42.6%) and the six profiles formed by combinations between categories of dietary pattern and nutritional status were associated with distinct sociodemographic characteristics, behaviors and sustainability indicators; (4) the height deficit (2.3%) was explained by biological variables and the worse socioeconomic position of the adolescents; the prevalence of obesity (10.0%) was associated with individual behaviors, psychosocial risk factors for health and better socioeconomic status; (5) the average carbon (1206 gCO2e / kg), water (2760 liters / kg) and ecological (8.07 g-m2 / kg) footprints were higher among adolescents in the South and Southeast, with a higher risk food pattern nutritional; (6) the prevalence of risk behaviors for eating disorders (16.5%) was associated with worse socioeconomic status, with individual behaviors and with psychosocial factors of greater vulnerability, with differences between the behaviors for weight loss (11.3% ) and those for weight gain or muscle mass (8.8%); (7) overestimation (6.6%) and underestimation (37.1%) of body image were associated with individual behaviors (sex, body satisfaction and risk behaviors for eating disorders); (8) the experience of household food insecurity (22.8%) was explained by the worse socioeconomic position, behaviors of greater food and nutritional risk and by psychosocial factors of greater vulnerability; and (9) body dissatisfaction coexists with nutritional deviations, food consumption with greater nutritional risk, food insecurity, inattentive eating, risky behaviors for eating disorders and better socioeconomic status. Based on the recognition of this entire context, (10) a model of management and production of food and nutritional care for Brazilian adolescents should be considered based on (a) incorporating new indicators into VAN, (b) qualifying educational actions for resilience and autonomy and (c) and in the development of public health, food and nutrition policies aimed at this population in Brazil.
