title: [Increase in cigarette smoking and decrease in the level of physical activity among Spanish adolescentes. AVENA study].
abstract: OBJECTIVE
  Cigarette smoking among adolescents as well as the level of physical activity constitutes a public health care issue. The aim is knowing the relationship between cigarette smoking and practice of physical activity.
  
  
  METHODS
  Schooled Spanish adolescents
  
  
  METHODS
  2859 Spanish adolescents (1357 boys, 1502 girls; age range: 13-18.5 years).
  
  
  METHODS
  A questionnaire is applied to know the level of cigarette smoking and four other questionnaires to know the level of physical activity during different periods.
  
  
  RESULTS
  40.8% of the adolescents stated not doing any physical activity at all, boys being more active than girls (p < 0.001). 29.9% of the adolescents stated usually smoking cigarettes, without differences by gender. Both active boys and girls stated smoking less (P < or = 0.01). The greater the age, the higher cigarette smoking and the lower the level of physical activity, both in boys and girls (p < 0.001).
  
  
  CONCLUSIONS
  The level of physical activity is low, being even lower for girls. Cigarette smoking shows a negative relationship with the level of physical activity, the individuals more physically active being those smoking the less.
