To assess the potential need, interest, and benefits of provision of contraceptive services in sexually transmitted disease (STD) clinics, we surveyed 516 women attending an inner-city STD clinic regarding contraceptive and sexual practices, STD prevalence, knowledge of contraceptive-related STD prophylaxis, and interest in contraceptive services within the STD clinic setting. The study population was at high risk for unintended pregnancy and STDs; at time of interview 46 per cent of women were not contracepting and 59 per cent were treated for STD or STD exposure. Two-thirds of women had at least one prior pregnancy and 50 per cent had at least one living child. Only 26 per cent of women knew that some contraceptive methods may reduce the risk of STD acquisition: however, 62 per cent expressed interest in contraceptive methods which would reduce their risk of STD acquisition. This study suggests that provision of contraceptive services in STD clinic settings may address dual needs in a group at high risk for both unintended pregnancy and STD.
