title: [Physical inactivity and anthropometric measures in school children from Paranavaí, Paraná, Brazil].
abstract: OBJECTIVE
  To investigate the association between physical inactivity and anthropometric measurements in school children from Paranavaí-Paraná, Brazil.
  
  
  METHODS
  Cross-sectional survey, conducted in July and August 2013. Sample of 566 students (287 boys and 278 girls) from 6th to 9th grade aged 10 to 14 years of public and private schools from Paranavaí-PR, Southern Brazil. The variables analyzed were: time of weekly physical activity by a questionnaire (physical inactivity <300 minutes/week), body mass index (BMI) and waist circumference (WC). In the statistical analysis the U Mann-Whitney and Student t test were used for comparison between genders. To identify factors associated with insufficient levels of physical activity, univariate and multivariate logistic regression analysis was applied and expressed in Odds ratio (OR) and 95% confidence interval (CI).
  
  
  RESULTS
  There was an association between physical inactivity and anthropometric measurements for BMI (p<0.001) and WC (p<0.001), with a prevalence rate of 56.1% and 52.7% of inactive adolescents, respectively. In the multivariate analysis, there was significant association of physical inactivity and overweight (OR 1.8, 95%CI: 1.1-3.0) and with increased waist circumference (OR 2.8, 95%CI: 1.4-3.8).
  
  
  CONCLUSIONS
  Inadequate levels of physical activity is a determining factor for overweight and abdominal adiposity. Accordingly, preventive measures should be taken, especially in schools, emphasizing the importance of exercise in the control of body composition and reduction of weight.
