Body weight and bleeding pattern changes in women using DMPA-SC.

Abstract

To determine the 1-year efficacy of contraception, changes in bleeding pattern and weight with the use of Depot medroxyprogesterone acetate-subcutaneous injected subcutaneously once every 3 months. Descriptive case-series. Gynaecology and Obstetrics Unit, Holy Family Hospital, Rawalpindi, from March 2003 to June 2004. Twenty five patients were selected by purposive sampling and followed up in Holy Family Hospital, Gynaecology and Obstetric Unit for a one-year period using DMPA-SC every three months. Hospital Ethical Committee permission was obtained prior to commencement of the study. Informed written consent was taken. Body weight was measured at baseline and every 3 months thereafter. Bleeding analysis in terms of blood flow and severity of bleeding was also done at 3 months interval using a 5-point scale. DMPA-SC showed 100% efficacy in preventing pregnancy in the 25 patients who were followed up. Mean and SD of age was 34.24+/-3.57 years. Mean and SD of weight was 63.44+/-13.81 kg.There was a mean weight gain of 0.1 kg at visit 1-3 (first 3 months) and an average weight gain of 1.036 kg at the end of the year. There was a trend towards amenorrhea with 56% of the patients included in the category of bleeding less than usual at the end of treatment period. DMPA-SC can be used in women desiring reversible contraception with unremarkable weight gain and overall bleeding pattern leading towards amenorrhea.
