Effect of Menstrual Bleeding on IUD Discontinuation

Am J Obstet Gynecol; ePub 2018 Aug 28; Hobby, et al

Women who reported baseline moderately heavy or heavy menstrual bleeding were not at increased risk for early intrauterine device (IUD) discontinuation, a recent study found.

Researchers performed a secondary analysis of the Contraceptive CHOICE Project, a prospective cohort study of 9,256 women offered no cost contraception for 2-3 years. Participants chose copper IUD for contraception and method continuation data at 12 months were analyzed. Prior to contraception initiation, participants were asked to qualify their menstrual bleeding over the past year as: light, moderate, moderately heavy, or heavy. Among the findings:

  • Of the 918 women meeting inclusion criteria, 165 were in the heavy bleeding group while 753 were in the not heavy bleeding group.
  • The 12-month continuation rates for groups were similar.
  • Patients reporting either moderately heavy or heavy baseline bleeding were not at increased risk for early discontinuation of copper IUD.
