| English abstract | BACKGROUND: Assess weight variations in Brazilian users of the 20 µg/day levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena®) for comparison with a cohort of users of the TCu 380A intrauterine device (IUD) and a cohort of users of the injectable contraceptive, depot-medroxyprogesterone acetate (DMPA) over a period of five years. METHODS: A total of 163 users of the LNG-IUS, who had the device inserted in 1998, were admitted to the study. At the time of enrollment, each woman was matched by weight (± 1kg) and age (± 1year) to a woman using a TCu 380A IUD and to another woman using DMPA. All women were followed up for a period of five years. Each year weight was measured and the body mass index (BMI, kg/m²) was calculated. RESULTS: Age of the LNG-IUS users was 27.0 ± 6.7 years (mean ± SD), while age of the copper IUD users was 28.0 ± 6.6 years and that of DMPA users was 26.9 ± 6.5 years. Weight recorded at the onset of the study was 62.9 ± 0.8 kg, 62.8 ± 0.8 kg, and 62.5 ± 0.9 kg (Mean ± SD) for users of the LNG-IUS, the copper IUD, and DMPA, respectively. The BMI of women was initially 25.0 (±0.3), 26.4 (±0.3), and 25.5 (±0.4), (Mean ± SD), for users of the LNG-IUS, copper IUD, and DMPA, respectively. Weight increases of 3.1 kg, 4.9kg and 8.2kg were observed at the end of the fifth year among users of the LNG-IUS, copper IUD, and DMPA, respectively (p = 0.009). Increase of the BMI was also observed among all groups (final BMI was 26.3 ± 0.7, 28.5 ± 0.8 and 28.7 ± 1.3 for users of the LNG-IUS, copper IUD and DMPA, respectively). Multivariate analysis showed that there was a significant association between weight increase and length of use of the contraceptive method and of the DMPA. CONCLUSION: The use of a LNG-IUS during five years caused no significant weight increase and the difference in weight was of the same magnitude as that of copper IUD users |
| Portuguese abstract | OBJETIVO: Determinar a variação de peso corpóreo em mulheres usuárias de sistema intra-uterino liberador de 20 mg/dia de levonorgestrel (SIU-LNG, Mirena®) e compará-la com a variação de peso de usuárias de dispositivo intra-uterino T cobre 380A (DIU Tcu) e usuárias de acetato de medroxiprogesterona de depósito (AMP-D) ao longo de cinco anos. MÉTODOS: Foram analisadas 163 mulheres usuárias de SIU-LNG que tiveram a inserção do mesmo em 1998 durante a admissão para o estudo. Cada mulher foi pareada por peso (± 1kg) e por idade (± 1 ano) no início do estudo, com as usuárias de DIU Tcu e AMP-D. Todas as mulheres foram seguidas por até cinco anos. Nesse período foram medidos seus pesos e calculados os índices de massa corpórea (IMC). RESULTADOS: A média de idade das usuárias de SIU-LNG foi 27±6,7 anos, enquanto que das usuárias de DIU Tcu foi 28±6,6 anos e das usuárias de AMP-D foi de 26,9±6,5 anos. O peso inicial era 62,9 ± 0,8 kg, 62,8 ± 0,8 kg e 62,5 ± 0,9 kg para as usuárias de SIU-LNG, DIU Tcu e AMP-D, respectivamente. O IMC no início do estudo era 25 (±0,3), 26,4 (±0,3) e 25,5 (±0,4) para as usuárias de SIU-LNG, DIU Tcu e AMP-D, respectivamente. Foi observado um aumento de peso de 3,1 kg, 4,9 kg e 8,2 kg para as usuárias de SIU-LNG, DIU Tcu e AMP-D, respectivamente, ao final do quinto ano (p=0,009). O IMC também apresentou um aumento em todos os grupos (IMC final de 26,3 ± 0,7, 28,5 ± 0,8 e 28,7 ± 1,3 para as usuárias de SIU-LNG, DIU Tcu e AMP-D, respectivamente). A análise multivariada mostrou que o uso de AMP-D e seu tempo de uso |
