This paper reports a hospital-based longitudinal study that was conducted in Zibo, China, in June 1996. The objective was to investigate the existing patterns of breastfeeding, amenorrhea and contraceptive use among postpartum women in urban areas of China. Information was obtained from 492 newly parturient women. Follow-up interviews were done at 42 days. 4 months and 1 year after delivery. The results showed that the full breastfeeding rate (including exclusive and almost exclusive breastfeeding) was 78% and 43% at 42 days and 4 months after delivery, respectively. The mean reported length of abstinence from sexual intercourse after delivery was 71 days. The mean reported time to menses resumption was 184 days. Ninety-three per cent of women had resumed sexual intercourse at 4 months after delivery. Seventy-three per cent of women were using contraceptive methods when they resumed sexual activity after delivery. After childbirth, the majority ofthe women interviewed used condoms within 3 months. Thereafter, most of them switched to intrauterine device (IUD)). Life table analysis shows that the continuation rates of full breastfeeding and amenorrhea at 4 months after delivery were 35% and 68%, respectively. This implies that if the full breastfeeding rate can be prolonged, it is feasible to use the lactational amenorrhea method (LAM) among Chinese postpartum women. The policy implications of this study are that quality care on contraceptive services and information for postpartum women in urban areas need to be improved further.
本文报告了一项于1996年6月在中国淄博进行的基于医院的纵向研究。目的是调查中国城市地区产后妇女的母乳喂养、闭经和避孕使用的现有模式。从492名新产妇那里获取了信息。在分娩后42天、4个月和1年进行了随访访谈。结果显示，分娩后42天和4个月时的纯母乳喂养率（包括纯母乳喂养和几乎纯母乳喂养）分别为78%和43%。报告的产后平均禁欲时间为71天。报告的月经恢复平均时间为184天。93%的妇女在分娩后4个月时恢复了性交。73%的妇女在分娩后恢复性活动时使用了避孕方法。产后，大多数接受访谈的妇女在3个月内使用避孕套。此后，她们中的大多数转而使用宫内节育器（IUD）。生命表分析显示，分娩后4个月时纯母乳喂养和闭经的持续率分别为35%和68%。这意味着，如果纯母乳喂养率能够延长，在中国产后妇女中使用哺乳期闭经法（LAM）是可行的。本研究的政策含义是，城市地区产后妇女避孕服务和信息的优质护理需要进一步改善。
