Effects of three contraceptive methods on depression and sexual function: An ancillary study of the ECHO randomized trial

To compare the effects of depot medroxyprogesterone acetate (DMPA-IM), levonorgestrel (LNG) implant, and copper intrauterine device (IUD) on mood and sexual function.

At the Effective Care Research Unit in South Africa, women already randomized in the ECHO Trial to the three methods were asked to participate in this study. Participants were interviewed at 3 and 12 months after enrollment using the Beck Depression Inventory and Arizona Sexual Experiences Scale, and at 12 months using the WHO-5 Wellbeing Index and the Patient Global Impression scale.

A total of 605 women participated. There was little difference in depression at 3 months across the three study groups. Contrary to our hypothesis, at 12 months, depression was lowest among DMPA-IM users (16/167, 9.6%) and highest among IUD users (28/158, 17.7%) (p = 0.032). There was little difference in sexual function at any time-point. More women in the DMPA-IM group felt "very much better" on the PGI scale than in the IUD and LNG implant groups (p = 0.003).

Depression may be less likely with DMPA-IM than with the other methods 1 year after initiation. Major differences in sexual functioning are unlikely. Unhappiness related to not using DMPA-IM, the most popular method in our setting, may have skewed results.
