title: [Tobacco consumption among the student population. Related factors].
abstract: OBJECTIVE
  To know smoking prevalence among schoolchildren and factors related with this habit.
  
  
  METHODS
  A cross-sectional study. 548 school-children in their 6th and 8th years of primary studies at schools from an area of Córdoba (Spain) were interviewed.
  
  
  METHODS
  Autoadministered questionnaire.
  
  
  RESULTS
  Tobacco was tried in 22% (CI 95%: 18.7-25.8) school-children. The average age for starting with this habit was 11.6 (SD)(CI 95%: 11.4-11.8). 12.1% smoked regularly and 1.3% smokers every day. The tobacco consumption in children was related with age (OR = 2.96; CI 95%: 1.12-7.82), cough medicines consumption (OR = 3.15; CI 95%: 1.32-7.48), to have a smokers sister (OR = 2.53; CI 95%: 1.06-6.00) and best friend (OR = 4.42; CI 95%: 1.85-10.60) and drinking beer (OR = 3.68; CI 95%: 1.15-11.7).
  
  
  CONCLUSIONS
  The prevalence of smoking in our school-children is very close to that reported by others. Among the factors accounted with the tobacco consumption in schoolchildren, highlight the presence of this habit in the eldest sister and the best friend.
