title: [Association between physical activity level and consumption of fruit and vegetables among adolescents in northeast Brazil].
abstract: OBJECTIVE
  To determine the association between low levels of physical activity and consumption of fruits and vegetables among adolescents.
  
  
  METHODS
  This cross-sectional study included 2,057 adolescents aged 13 to 18 years from the city of Aracaju, Northeastern Brazil. We analyzed the level of physical activity, consumption of fruits and vegetables by standardized and validated questionnaires. The control variables were sex, age, socioeconomic status, maternal education, alcohol consumption and smoking. For data analysis, univariate and multivariate logistic regression were used, with a significance level of 5%.
  
  
  RESULTS
  The prevalence of low levels of physical activity was 81.9%; the inadequate consumption of fruits ocurred in 79.1% and the inadequate consumption of vegetables in 90.6%. Adolescents who consumed few fruits daily had an increase in 40% of chance of being insufficiently active and, for those who consumed few vegetable,s the likelihood of being insufficiently active was 50% higher, compared to those who had adequate intake of these foods.
  
  
  CONCLUSIONS
  Low levels of physical activity were associated with inadequate fruit and vegetable intake among adolescents in a city in northeastern Brazil. These findings suggest that insufficiently active adolescents have other unhealthy behaviors that may increase the risk of chronic diseases in adulthood.
