title: Effect of advanced provision of emergency contraception on women's contraceptive behaviour: a randomized controlled trial.
abstract: BACKGROUND
  Emergency contraception (EC) can prevent pregnancy but is under-used. Advanced provision increases use but the effect on contraceptive behaviour varies.
  
  
  METHODS
  Women aged 18-45 years, using less effective contraceptives, were randomized to either advanced provision of three courses of EC (intervention) or to obtaining each course from clinic (control). EC use and contraceptive behaviour were monitored for 1 year.
  
  
  RESULTS
  In all, 1030 women were recruited in 6 months. The mean+/-SD number of courses of EC used in intervention versus control group was 0.56+/-1.2 versus 0.20+/-0.6 (P<0.001). In the intervention group, 47% women aged <26 years used at least one course of EC compared with 23% of older women (P<0.001). The majority of women used condoms before (intervention 89%, control 91%) and during the study (89% for both groups). Consistency of contraceptive use was higher during the study (65 versus 60% of women in both groups) (P<0.001). There were 17 unplanned pregnancies, eight in the intervention group, six of whom did not use EC in the conception cycle.
  
  
  CONCLUSIONS
  Advanced provision increases EC use especially among young women in Hong Kong. Contraceptive choice and consistency of use remains the same even among young women.
