title: Knowledge and use of emergency postcoital contraception by female students at a high school in Nova Scotia.
abstract: OBJECTIVE
  This study was performed in the context of a sexual health promotion project in a Nova Scotia community. Community members wanted information about adolescent females' knowledge and use of emergency contraception (EC). The study was done to meet this need.
  
  
  METHODS
  Female high school students aged 14 to 19 were administered a self-completion survey asking about their knowledge of EC, the time frame for its use, its effectiveness, their personal use of EC, unsuccessful attempts to obtain EC, and sources of knowledge of EC.
  
  
  RESULTS
  Eighty-five percent of 411 female students participated. Eighty percent knew about EC, though few (8%) knew the time frame for EC use. Most (42%) heard of EC at school. Eighteen percent used no contraception at last intercourse. Only 2% ever had used EC.
  
  
  CONCLUSIONS
  Adolescent women know about EC but use it infrequently, even though they frequently lack contraception. These findings raise questions about alternative methods for providing EC to young women.
