Weight Gain with the Levonorgestrel-Releasing Intrauterine System (LNG-IUS) Versus Depot Medroxyprogesterone Acetate (DMPA) Among Post- Partum Adolescents through 12 Months of Follow-up

Objective: To explore trends in weight gain among post-partum/parous adolescents using either DMPA or the LNG-IUS. Materials and Methods: Secondary analysis using data from a longitudinal survey of 66 post-partum/parous adolescents choosing either DMPA or the LNG-IUS as their method of contraception. Results: At 3, 6 and 12 months of follow up there was no statistically significant difference in weight gain between DMPA and LNG-IUS users. There was an association between weight gain at 3 and 6 months, respectively, and weight gain at 12 months. Conclusions: Further studies are needed to validate the intriguing findings of this small study.
