Outcome’s Comparison of DMPA and IUD Among Users 12-18 Month After Starting Methods

Backgrounds: DMPA and IUD are among the most effective reversible contraception in the world and also in Iran. Although, in Iran both methods are available and present to the woman in free, in the last decade we encountered to significant increase in trend of DMPA users. Therefore, the aim of this study was to compare some of the side effects of these two methods.Material and Method: This retrospective cohort study was conducted on 300 healthy married women aged 19-50 during June- December 2018 in Tehran. Samples were selected from 31 centers and 57 sub-center. We contacted to 1200 women and finally 300 women had the study criteria and accepted to participate in the research. 150 women with DMPA and 150 women using IUD who started their Method for 12-18 month invited to the study. Menstrual bleeding and menstrual pattern by Higham chart and questionnaire; dysmenorrhea by visual analogue diagram of VAS has been measured by women during 2 months of self-reporting. In addition, weight changes and consumer’s method satisfaction have been assessed.Result: The mean age of participated women was 33.7 ± 5.5 years. Although, menstrual bleeding in IUD users was significantly higher than DMPA users (P<0.001), no meaningful difference reported between dysmenorrhea and spotting between two groups. Weigh changes during this 12-18 month, in DMPA group was 2 kilograms more than IUD groups that show significant difference (P<0.001). Despite the amount of bleeding increased in IUD users, method satisfaction and method recommendation to other was significantly higher in IUD users in comparison of DMPA users (P<0.001).Conclusion: The results of this study showed that IUD is preferable method on those who have the indication of using both methods and we cannot assume that the change in trend of using DMPA and IUD is simply due to their side effects.
