title: Risk factors of tobacco use among Thai adolescents: finding from International Tobacco Control Policy Survey Southeast Asia (ICT-SEA).
abstract: OBJECTIVE
  To determine the risk factors of tobacco use among Thai adolescents.
  
  
  METHODS
  A cross-sectional study was conducted among 706 adolescents sampled from 5 regions of Thailand using stratified multistage sampling. Participants were asked to complete self-administered questionnaires about tobacco use and psychosocial factors. A logistic regression model of risk factors for tobacco use was estimated using backward stepping.
  
  
  RESULTS
  The prevalence of smoking in Thai adolescent was 15 percent (27.8% in males, 2.3% in females). Older age (OR = 1.25, 95% CI = 1.02-1.51), number of close friend smoking (OR = 1.61, 95% CI = 1.35-1.93), number of older sibling smoking (OR = 1.44, 95% CI = 1.01-2.04), heavy alcoholic consumption (OR = 3.99, 95% CI = 1.87-8.49), low self-worth (OR = 3.16, 95% CI = 1.71-5.84) were risk factors of smoking in Thai adolescents. Females (OR = 0.10, 95% CI = 0.04-0.24), currently studying in school (OR = 0.33, 95% CI = 0.18-0.59) and religious beliefs guide actions (OR = 0.41, 95% CI = 0.22-0.77) were protective factors against smoking.
  
  
  CONCLUSIONS
  Male adolescents are target group for tobacco control in Thailand. The strong correlation between smoking and alcoholic consumption indicate that anti-smoking campaign should be done in parallel with anti-alcohol campaign.
