title: Health factors related to physical activity among children and adolescents: results from Spanish National Health Surveys 2006 and 2011/12.
abstract: OBJECTIVE
  To describe the prevalence of physical activity during leisure time among children ages 6-14 in 2006 and 2011/12.
  
  
  METHODS
  A cross-sectional study used individualized data for children 6-14 years of age from the Spanish National Health Surveys in 2006 (n = 5,108 children) and 2011/12 (n = 3,265 children).
  
  
  RESULTS
  Leisure time decreased between 2006 and 2011/12(p < .05). Variables associated with increased physical activity were: normal weight (odds ratio [OR] = 1.87; 95% confidence interval [CI]: 1.37-2.57), children perceived to be in good health by their parents (OR = 2.03;95% CI: 1.43-2.87), and less than 2 hr of screen time per day(OR = 2.00; 95% CI: 1.61-2.47).
  
  
  CONCLUSIONS
  Primary care-based nurses are essential to improving adherence to physical activity.
