Emergency contraception: who are the users?

The objective was to describe the demographic and sexual characteristics of clients attending a Sexual Health Clinic for emergency contraception (EC). Information about women attending the Parramatta Sexual Health Clinic (PSHC) who received EC between January 1999 and July 2002 was derived from the clinic database. Age-matched controls were randomly selected. Univariate and logistic regression analysis was performed to establish which factors were associated with use of EC. Two hundred and sixty-seven women requesting EC and an equal number of controls were studied. Factors that were independently associated with EC use were being a student (OR=1.7 [95% CI 1.02–2.69]) and having a regular sexual partner (OR=2.3 [95% CI 1.14–4.73]). Women requiring EC were significantly less likely to have had a sexually transmitted infection (STI) (OR=0.3 [95% CI 0.16–0.60]) or a previous pregnancy (OR=0.2 [95% CI 0.09–0.67]) than controls. We concluded that users of EC are at low-risk for STIs but need counselling about safer sex. (authors)
