title: Ages at initiation of cigarette smoking and quit attempts among women: a generation effect.
abstract: OBJECTIVE
  This study sought to determine whether the age at initiation of regular cigarette smoking and the likelihood of quitting smoking through age 35 differ among women from younger versus older generations.
  
  
  METHODS
  Annual population-based, random surveys (total of 3676 female residents of Geneva, Switzerland, aged 35-74 years) were conducted from 1992 to 1998.
  
  
  RESULTS
  Women younger than 55 years were more likely to be past or current smokers, began smoking earlier (median age < 20 years), and smoked more cigarettes per day than older women, yet attempted to quit smoking more often before age 35 (log-rank P <.001).
  
  
  CONCLUSIONS
  Young female smokers have a higher propensity to quit smoking compared with older women. Encouraging young smokers to quit-in addition to preventing nonsmokers from starting-may be an important facet of reducing cigarette smoking prevalence among adolescents.
