ObjectiveTo analyze whether psychosocial factors and physical activity are predictors of fruit and vegetable intake in young adults attending college. MethodsThis cross-sectional study included a representative sample of students from a public university in the Brazilian Northeast (n=717). Fruit and vegetable intake was measured by a Food Frequency Questionnaire containing 21 items. The psychosocial factors for behavior change, measured by a questionnaire, were: behavior change strategy, self-efficacy, perceived barriers and facilitators in decision making, and social support. The level ofphysical activity was measured by the International Physical Activity Questionnaire. Multiple linear regression was the intake prediction model using a significance level of 5% (p<0.05). ResultsThe median fruit and vegetable intake was 2.0 servings/day. In adjusted analysis, behavior change strategy (R²=0.31), self-efficacy (R²=0.03), friends’ support (R²=0.02), and physical activity (R²=0.03) explained 39% of the fruit and vegetable intake variance in men. Behavior change strategy (R²=0.03), self-efficacy (R²=0.13), perceived barriers (R²=0.08), and physical activity (R²=0.02) explained 26% of the fruit and vegetable intake variance in women. Fruit and vegetable intake would increase by one serving for every extra 35 and 47 minutes of physical activity men and women, respectively, practice a day. ConclusionThe main predictors of fruit and vegetable intake are behavior change strategies, self-efficacy, and physical activity.
