title: [Smoking trajectories among Hungarian adolescents].
abstract: BACKGROUND
  Understanding adolescent smoking trajectories is necessary for tailored prevention programs.
  
  
  OBJECTIVE
  To identify adolescent cigarette use patterns and risk factors of smoking trajectories by a longitudinal study.
  
  
  METHODS
  We conducted a three-year prospective survey in two age cohorts (6th and 9th school grades) of metropolitan adolescents (n = 1,092) with yearly data collection by self-administered questionnaires. Five smoking trajectory groups were defined by cigarette smoking data.
  
  
  RESULTS
  67.5% of the sample remained nonsmoker, 11.3% smoked all the time, 14.3% were initiators, 3.3% quitters and 3.7% experimenters. Members of smoking trajectory groups differed significantly from each other according to number of smoking friends, parental smoking, family structure, academic achievement and weekly allowance at baseline.
  
  
  CONCLUSIONS
  Concerning tobacco prevention programs, adolescents are not homogenous population, because distinct set of risk factors are highlighted in their different smoking behavior groups. Orv. Hetil., 2017, 158(2), 67-76.
