The postpartum period represents a key opportunity for women to learn about and obtain effective contraception, especially since 50% of unintended pregnancies to parous women occur within 2 years of a previous birth. Methods: We conducted a prospective cohort study of 800 postpartum women recruited from three hospitals in Austin and El Paso, TX. Women aged 18-44 who wanted to delay childbearing for at least 24 months were eligible for the study and completed interviews following delivery and at 3 and 6 months postpartum. Participants were asked about the contraceptive method they were currently using and the method they would prefer to use at 6 months after delivery. Results: At 6 months postpartum, 13%of women were using an intrauterine device or implant, and 17%were sterilized or had a partner who had had a vasectomy. Twenty-four percent were using hormonalmethods, and 45%relied on less effective methods, mainly condoms and withdrawal. Yet 44% reported that they would prefer to be using sterilization, and 34% would prefer to be using long-acting reversible contraception (LARC). Conclusions: This study shows a considerable preference for LARC and permanent methods at 6 months postpartum. However, there is a marked discordance between women's method preference and actual use, indicating substantial unmet demand for highly effective methods of contraception. Implications: In two Texas cities, many more women preferred long-acting and permanent contraceptive methods (LAPM) than were able to access these methods at 6 months postpartum. Women's contraceptive needs could be better met by counseling about all methods, by reducing cost barriers and by making LAPM available at more sites.
