Key clinical point: Women who used progestin-only contraceptives experienced significantly greater weight gain than those using nonhormonal copper intrauterine devices.
Major finding: After 18 months, all treatment groups gained weight, but the average gain in the DMPA-IM group (3.5 kg) was significantly higher compared with both the LNG implant group (2.4 kg) and copper IUD group (1.5 kg).
Study details: The data come from a secondary analysis of women enrolled in the Evidence for Contraceptive options and HIV Outcomes (ECHO) trial and included 7,829 women aged 16-35 years seen at 12 sites in Kenya, South Africa, and Zambia between December 2015 and October 2018. Of these, 2,609 received intramuscular depot medroxyprogesterone acetate (DMPA-IM), 2,613 received a levonorgestrel (LNG) implant, and 2,607 received a copper intrauterine device (IUD).
Disclosures: The study was supported by the Bill & Melinda Gates Foundation, US Agency for International Development (USAID) and the President's Emergency Plan for AIDS Relief, Swedish International Development Cooperation Agency, South African Medical Research Council, and UNFPA.
