title: Women at risk for sexually transmitted diseases: correlates of intercourse without barrier contraception.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the correlates of vaginal intercourse without barrier contraception (unprotected intercourse).
  
  
  METHODS
  Baseline data from a randomized trial were analyzed to evaluate factors that are associated with intercourse without barrier method use among women < 35 years old. Logistic regression models provided estimates of the association of demographic, reproductive, and sexual history variables with unprotected intercourse.
  
  
  RESULTS
  Intercourse without barrier contraception was common; 65% of participants had > or = 2 episodes of intercourse without barrier contraception use in the past month. Factors that were associated with increased odds of unprotected intercourse included the number of coital episodes, a male partner's unwillingness to use condoms (adjusted odds ratio, 4.1; 95% CI, 2.3-6.9), and, among women < 20 years old, low condom use self-efficacy score (adjusted odds ratio, 1.6; 95% CI, 1.0-2.9).
  
  
  CONCLUSIONS
  Risk factors for unprotected intercourse included coital frequency and the male partner's unwillingness to use condoms. Self-efficacy for condom use was especially important for women < 20 years old.
