title: [Physical activity and leisure time in children. I: Relation to socioeconomic status].
abstract: OBJECTIVE
  To assess physical activity and leisure time activities in relation to socioeconomic status.
  
  
  METHODS
  We have studied 1,078 boys and girls from 24 schools from areas of different geographical and socioeconomical status. Physical activity and leisure time activities were assessed by a questionnaire.
  
  
  RESULTS
  We have observed that adolescents spend more time watching T.V. than doing physical activity (p = 0.0001). In general, boys prefer strong physical activity. Children from the lowest socioeconomic families did less physical activity than children from the highest socioeconomic families (p < or = 0.05). In girls, those with the lowest socioeconomic status spent the greatest amount of time watching T.V. (p = 0.0001).
  
  
  CONCLUSIONS
  From our results, we deduce that we must improve physical activity habits in children, especially in those from the lowest socioeconomic families.
