Psychosocial aspects related to fruit and vegetable consumption in adolescents/Aspectos psicossociais relacionados ao consumo de frutas e hortalicas em adolescentes

This study aimed at assessing the association between psychosocial aspects and fruit and vegetable consumption in adolescents. Cross-sectional study developed with 327 adolescents from a public school in Brazil. A questionnaire developed for adolescents was applied to assess the influence of self-efficacy, family, peers, and body image on the consumption of fruits and vegetables. Specific questions assessed the intake frequency of fruits and vegetables, and the mean consumption was estimated using two 24-hour recalls. Scores related to psychosocial aspects were described as mean and median and the weight status was classified based on the body mass index. The average daily consumption of fruits and vegetables was 36.2 g and 45.4 g, respectively. Sel-f-efficacy and the influence of peers were associated with an increase in the amount and frequency of fruits and vegetables consumption. Adolescents with higher scores of self-efficacy had greater average consumption of fruits and vegetables when compared to those with lower scores. The same was observed for the influence of peers. Self-effi-cacy and the influence of peers were the factors that most influenced the consumption of fruits and vegetables in adolescents.
