Reuters is reporting that black women were the most likely to gain weight while using a long-acting form of contraception, such as a hormone implant or intrauterine device (IUD), in a small new study.
Researchers found that during a year of using progestin-based long-term contraceptives, black women put on an average of four to six pounds, compared to a trend of slight weight loss or smaller weight gain for white and other women.
But Dr. Jeffrey Peipert, who worked on the study, cautioned against blaming the implants, injections and IUDs for the extra weight gain among certain women.
“Anecdotally, many doctors have had patients coming in and saying, ‘I’m gaining weight and I think it’s my contraceptive method and I want to stop using it,'” said Peipert, from Washington University School of Medicine in St. Louis.
“People don’t realize that the norm, while it may not be good, (is to) gain weight over time, and it may or may not be your method.”
The findings are based on 427 women who were part of a larger study in which participants were provided with one of four types of contraception at no cost: a copper IUD or an implant, injection or IUD that delivers the hormone progestin over time.
