title: Repeat use of emergency contraceptive pills in urban Kenya and Nigeria.
abstract: BACKGROUND
  Little is known about the frequency and patterns of use of emergency contraceptive pills among women in urban Kenya and Nigeria.
  
  
  METHODS
  To recruit women who had used emergency contraceptive pills, individuals aged 18-49 were intercepted and interviewed at shopping venues in Nairobi, Kenya, and Lagos, Nigeria, in 2011. Information was collected on 539 Nairobi and 483 Lagos respondents' demographic and behavioral characteristics, attitudes toward the method, and frequency of use. Multinomial logistic regression analyses were used to identify associations between these characteristics and frequency of pill use.
  
  
  RESULTS
  Eighteen percent of the women interviewed in Nairobi and 17% in Lagos had ever used emergency contraceptive pills. On average, these respondents had used the pills less than once per month, but greater use and acceptance were seen in Lagos. In multivariate analysis, women who had sex at least once in a typical week were generally more likely than others to have used the pills 2-5 times in the last six months, rather than once or never, or to have used them six or more times. Furthermore, Lagos respondents who said their main contraceptive method was the condom, the pill or injectable, or a natural method were generally less likely than those who did not report these methods to have used the emergency pills multiple times in the last six months.
  
  
  CONCLUSIONS
  Repeated use of emergency contraceptive pills was not common in this sample.
