Objective |
We sought to compare complication and continuation rates of the levonorgestrel intrauterine system (LNG-IUS) with the subdermal etonogestrel (ENG) implant across the United States among girls and women 15-44 years of age.
Study Design |
A retrospective study of health insurance claims records from 2007 through 2011 identified a cohort of women who had LNG-IUS (n = 79,920) or ENG implants (n = 7374) inserted and had insurance coverage for 12 months postinsertion. Claims for complications were examined 12 months after insertion, or until removal of either device within each of 3 age groups.
Results |
After its introduction in 2007, the frequency of ENG implants increased each year and almost a third of all insertions were in teenagers. However, among women ≤24 years old who had delivered an infant in the prior 8 weeks, a LNG-IUS was more likely to be inserted than an ENG implant ( P < .05). The most frequent complications with both methods were related to abnormal menstruation, which was more likely to occur among ENG implant users. Overall, 83-88% of the entire sample used their chosen method for at least 12 months. The odds of continuation were similar for both methods among teenagers, but ENG implants were more likely to be removed prematurely among women 20-24 years old (odds ratio, 1.21; 95% confidence interval, 1.06–1.39) and 25-44 years old (odds ratio, 1.49; 95% confidence interval, 1.35–1.64).
Conclusion |
Both of these long-acting contraceptive methods are well tolerated among women of all ages, and demonstrate high continuation rates.
