Abstract
Introduction: body composition (BC) and bone mineral density (BMD) in women depends on numerous factors that occur during reproductive life and/or postmenopause, as peak bone mass, body weight, genetic factors, lifestyle, and contraception. The contraceptive methods as progestin-only methods like subdermal implants play an effects on BMD and BC still conflicting in the literature. Objective: To evaluate BMD and BC of 2 groups of women: users of etonogestrel-releasing contraceptive implant (Implanon) and users of intrauterine device (IUD) TCu380A. Subjects and methods: this will be a prospective cohort study. Each user of implant will be compared to a user of IUD TCu380A. We will enroll 80 women, 40 implant users and 40 controls IUD TCu380A users. In all patients we will measured BMD (spine and femoral neck) and CC at baseline and after 1 year of follow-up, using dual-energy x-ray absorptiometry (Lunar DEXA). Analysis: Chi-square test for categorical variables was apply and BMD data at spine and femoral neck will be compared between groups by test t Student. (AU)
