The average length of postpartum amenorrhea reported by breast-feeding women in rural Bangladesh in 1975 was 18 to 20 months. Its duration was found to be only slightly related to maternal nutritional status. There was no evidence of a threshold of weight for height necessary for the resumption of menses postpartum. Factors related to the duration of postpartum amenorrhea were maternal age, socioeconomic status, and supplemental feeding of the infant.
1975年,孟加拉国农村地区母乳喂养女性报告的产后闭经平均时长为18至20个月。研究发现,其持续时间与母亲的营养状况仅有轻微关联。没有证据表明产后月经恢复存在身高体重阈值。与产后闭经持续时间相关的因素有产妇年龄、社会经济地位以及婴儿的补充喂养情况。
