ABSTRACT
PIP: A retrospective study of 144 US women 14-21 years of age who requested and received the Norplant contraceptive implant system at the Mayo Clinic (Rochester, Minnesota) in 1990-93 analyzed the factors associated with duration of method use. Of the 124 women who reported past use of contraception, 94 (76%) had been pregnant at least once. The method most commonly used before Norplant was oral contraception (57%). The reasons for Norplant selection were its convenience (86%) and problems tolerating the pill (14%). Of the 130 Norplant users who either telephoned or made a clinic appointment after insertion, 60% reported side effects such as breakthrough bleeding, headache, and depression or mood swings. 64 women had the implants removed. The median duration of Norplant use was 29 months. The Kaplan-Meier estimate of the probability of the Norplant system remaining in place for at least 12 months was 83% and 63% for at least 24 months. Age, prior contraceptive use, and timing of insertion had no impact on duration of Norplant use. Multivariate analysis indicated that women with at least 1 prior pregnancy had a two-fold increased risk of Norplant removal compared to those who had never been pregnant. Larger studies are needed to identify additional factors associated with long-term use of injectable contraception among young women and to suggest interventions that would improve compliance with routine follow-up.
