title: APC modeling of smoking prevalence among US adolescents and young adults.
abstract: OBJECTIVE
  To investigate the association of age, period, and cohort with the changing pattern of cigarette smoking among youth and young adults for better planning tobacco control in the United States.
  
  
  METHODS
  Age-period-cohort analysis of the 1990-2005 National Survey  on Drug Use and Health data.
  
  
  RESULTS
  Rates of lifetime and 30-day smoking for adolescents fluctuated between 1990 and 1996 before they declined; the same rates for young adults progressively increased until 2002 before declining. There were significant cohort effects on changes in  the prevalence rates of cigarette smoking.
  
  
  CONCLUSIONS
  The cohort effects on smoking underscore the need for sustained tobacco control policies.
