摘　　要：为研究哺乳与哺乳性闭经时间的关系,本文对541对二胎母婴自分娩后7天内至母亲恢复正常月经期间婴儿喂养及相关情况进行了随访研究。结果显示,喂奶次数和时间随产后时间变化不大。产后半年内,婴儿摄食90％以上为母乳,至婴儿一岁,母乳含量仍约70％。开始添加辅食的平均时间为产后153天。产后2周全母乳喂养率为73.4％,产后3月、6月分别约为60％和40％。产后一年半,仍有近80%的母亲部分母乳哺喂孩子。产后61,89,187和369天,母亲恢复月经累计概率分别为0.0150,0.0395,0.2345和0.6820。哺乳性闭经时间平均为282天。结果说明:全母乳喂养和以母乳为主的喂养时间较长和添加辅食较晚的母亲闭经时间较长。产后首次月经的出现是应采用避孕措施的信号。To study the relationship between infant feeding practices and the duration of lactational amenorrhoea, this paaper reprots a detailed follow - up survey. A detailed follow-up survey was conducted among 541 pairs of mothers and infants from delivery to the returning of menses of mothers at the interval of every two weeks. The results showed that the mean number of breast - feeding episodes and mean duration of breastfeeds had little correlation with the time since delivery. within 6 months since delivery, the percentage of infants' feeds consisting of breastmilk was over 90% ,and this percentage dropped to 70% at one year's age of infants. The time to the start of regular supplementation was 153 days postpartum. The proportion of women in exclusive breastfeeding at two weeks postpartum was 73.4%, and these figures at 3 and 6 months postpartum were about 60% and 40% respectively. Nearly 80% mothers were partially breastfeeding their inlants more than 18 months postpartum. The cumulative probabilities of menses returning were 0.0150,0.0395,0.2345 and 0.6820 at 61,89, 187 and 369 days postpartum respectively. The median duratoin of lactalional amenorrhoea was 282 days. These results indicated that the duration of lactational amenorrhoea would be prolonged if the time of exclusive/predominant breastfeed was extended and the supplementary food was introduced later. The paper concluded that the first menses returning was the signal for initiating contraceptive methods in women.
