title: Drug use among adolescent mothers: prepregnancy to 18 months postpartum.
abstract: OBJECTIVE
  Little is known about the substance use patterns of adolescent mothers, particularly in the postpartum period. This study provides descriptive, longitudinal data on the substance use behavior of a cohort of adolescent mothers.
  
  
  METHODS
  A total of 241 pregnant adolescents, under 18 years old and planning to carry the pregnancy to term, completed the initial interview. Respondents were interviewed again at 1, 6, 12, and 18 months postpartum. The data reported here are based on the 229 respondents who completed all five interviews.
  
  
  RESULTS
  Use of all substances decreased substantially during pregnancy, but increased steadily in the first 6 months postpartum. A similar pattern was observed for regular use of multiple substances. Regular use before and after the pregnancy, but not during it, was the most common pattern of substance use.
  
  
  CONCLUSIONS
  The prevalence of substance use among adolescent mothers is significant. To capitalize on the large decreases in use during pregnancy, drug prevention programs for adolescent mothers should target the first 6 months postpartum.
