RESUMO

OBJECTIVE: This study evaluated body composition and bone mineral density in users of levonorgestrel-releasing intrauterine system (LNG-IUS) and compared to TCu380A intrauterine device (IUD) users. SUBJECTS AND METHODS: A prospective group study conducted for 12 months with 38 LNG-IUS users and 38 TCu 380A IUD users, were paired by age (± 2 years) and the body mass index (kg/m²) (±2), recruited at Woman Hospital of University of Campinas (Unicamp). Two evaluations were realized about the body composition and bone mineral density of the Lumbar Spine (L1-L4), femoral neck and total femur through the technique of dual x-ray absorciometry (DEXA). The first evaluation is going to be at the beginning of the use of the contraceptive method and the second will be after the method has been used for one year. The data was evaluated trough t- Student test for paired samples, Wilcoxon, and Chi-square. RESULTS: The mean (±SEM) age was 34.4 (±1.2) years old and 34 (±1.3) years old, BMI was 25.1 (± 0.7) and 25.9 (± 0.7) and with 1.9 (±0.2) and 1.7 (±0.2) pregnancies in LNG-IUS and TCu380A IUD users, respectively. There was a significant decrease in BMD of 0.5% in LNG-IUS at LS and an increase of 1.4% and 1.5% in TCu380A IUD users at FN and LS, respectively when compared values at baseline and at one year of use. The two groups had an increase in body weight; however, without significance between groups at 12 months. LNG-IUS users showed a fat percentage increased; notwithstanding, the TCu380A IUD users had an increase of lean mass, both at 12 months. CONCLUSIONS: It was observed a small loss of BMD up to the 1st year of LNG-IUS use; probably without clinical significance. The TCu380A IUD users presented increase of lean mass and increase of BMD at FN and LS
