Weight Change Among Users of Three Progestin-Only Methods of Contraception Over a 12-Month Time Period (BMI)
The purpose of this study is to learn whether women who use progestin-only methods of birth control such as the contraceptive implant (Implanon), the levonorgestral-releasing IUS (Mirena), or depot medroxyprogesterone acetate(DMPA) will experience weight change compared to women using the non-hormonal copper IUC (ParaGard).
The investigators primary hypothesis is that users of DMPA will gain excess weight and increase their BMI above the copper-IUC users; secondarily, the investigators will compare users' data in the LNG-IUC and ENG implant groups to the copper-IUC group.
