Comparison Of Weight Increase In Users Of Depot Medroxyprogesterone Acetate And Copper Iud Up To 5 Years.

The objective of this study was to evaluate retrospectively the weight variation in long-term users of depot medroxyprogesterone acetate (DMPA) compared to users of the TCu380A intrauterine device (IUD). A cohort of 206 healthy women allocated in two groups of 103 women according to the contraceptive method used was evaluated through 5 years. Each user of DMPA was paired with an IUD user by age (+/- 1 year) and weight (+/- 1 kg) at the beginning of the study. Weight was evaluated yearly during 5 years. The mean age at the beginning of the study was 33.1 years in both groups, and the mean weight was 59.4 kg in the IUD users and 60.4 kg in the DMPA group. Both cohorts of women presented significant weight increase at the end of the 5 years of observation (p < 0.001). However, DMPA users presented higher weight increase when compared to IUD users from the second through the fifth year of observation. The DMPA users increased weight by 4.3 kg during the 5 years, and IUD users increased 1.8 kg. In conclusion, DMPA users had a significantly higher weight increase when compared to IUD users. In addition, this cohort of women increased weight throughout the 5 years with the use of DMPA or IUD.64223-
