BACKGROUND: This study is an exploration of the relationship between the use of oral contraceptive or intrauterine device and condom use. The results should help us better understand how promoting condoms for contraception as compared to sexually transmitted disease prophylaxis might be an effective way of increasing their use in certain populations.¦METHODS: Women not involved in stable relationships were selected from the French National Survey on Sexual Behaviour using multi-stage probability sampling. We compared frequency of condom use at the last sexual intercourse by women who were using prescribed contraception with that by women who did not. Odds ratios (OR) were adjusted for age, duration of the relationship, education, type of partner and number of partners in the last 12 months.¦RESULTS: Overall, no difference was found in the frequency of condom use during the last sexual intercourse by women who were using prescribed contraception compared with women who were not. A more frequent use of condoms tended to be associated with the absence of contraception in relationships of less than three months' duration (adjusted OR: 4.5; 95% CI: 0.7-33.3) and for women of 25 to 34 years of age (adjusted OR: 2.4; 95% CI: 0.8-7.1).¦CONCLUSION: Many factors other than contraceptive practice influence the use of condoms. Nevertheless, our results suggest that reproductive issue should be taken into account in specific subgroups of the population when developing policies to prevent sexual transmission of HIV.
