注射醋酸甲孕酮妇女月经改变的相关因素分析

目的:研究注射醋酸甲孕酮(DMPA)妇女月经改变的相关因素。方法:将390例受试者分为哺乳组和非哺乳组两组,对多种数据进行回归分析。结果:注射DMPA次数越多,体质指数越大,哺乳时间越长,发生问经的可能性越大,而经量多的妇女越容易发生不规则流血。注射期间持续阴道流血不闭经妇女和闭经妇女在初潮、经期、周期、经量、注射次数、是否哺乳六个指标上均有显著性差异。结论:本研究为注射前预测妇女月经改变提供了一定的咨询参考。

Analysis of factors relating to menstrual changes in women receiving injections of Depo-medroxypro- gesterone acetate.

Objective: To research the factors relating to menstrual changes in women injected with depo-medroxyprogesterone acetate (DMPA). Method: 390 subjects were divided into two groups : the breastfeeding and the nonbreast-feeding group. Data from the various records were fed into a computer and performed the regression analysis. Results: Number of DMPA injections, body mass index, and duration of lactation are positively related to higher probability of amenorrhea, and women with menor-rhagia tend to experience irregular bleeding. Women who were not amenorrheic and continued to experience vaginal bleeding during the injection period and women who were amenorrheic had significant dif-firences with respect to six indices: menarche. menstrual period, menstrual cycle, menstural volume, number of injections, and breast-feeding. Conclusion: The study provides a definite consultative reference for making pre-injection predictions on menstrual changes in women.
