“A multiyear study of intrauterine devices (IUDs) shows that the popular birth-control device is five times more likely be expelled if it is inserted right after childbirth. The study was published Feb. 28 in the JAMA Network Open.
The study included the examination of more than 326,000 IUD insertions between 2001 and 2018. The Association of Perforation and Expulsion of Intrauterine Devices (APEX-IUD) cohort study included women ages 50 years or younger. Only the first IUD insertion during the study period for each individual was included in this analysis.
“The first goal of this analysis was to see if there was a higher risk of IUD expulsions in the year following a delivery, while the second goal was to see if breastfeeding increased or decreased the risk of expulsion,” said Dr. Susan Reed, one of the study authors and an OB-GYN with the University of Washington School of Medicine.
The study identified nearly 9,000 IUD expulsions. Average age of individuals in the study was 32. The population was diverse – about 60% were Hispanic or nonwhite. When an IUD was inserted immediately after childbirth or within three days of delivery, the cumulative risk of expulsion over five years was about 11%. This risk was five times greater than that among women who had an IUD placed more than a year after delivery or who had never been pregnant. If an IUD was inserted six weeks to 14 weeks after childbirth, the cumulative five-year expulsion rate dropped to 3%.”
