Using a 24-month cohort study of 1700 women who delivered in eight Texas hospitals and were uninsured or publicly insured at the time of delivery, we focused on 456 women who used short-acting hormonal contraception within 6 months after delivery. We classified this sample according to characteristics and method preference, and estimated rates of discontinuation and associated predictors using life tables and Cox models. We assessed reasons for discontinuation and subsequent contraceptive use among those who discontinued.
