摘　　要：本研究观察 1 0 0 0例产妇的排卵恢复情况 ,从产后第 2周起对产妇用 B超及尿 L H测定进行监测。监测结果 :产后排卵恢复时间最早为 1 4d,最长为 53 7d,第 50百分位数为56 d。母乳喂养、混合喂养和人工喂养三组产妇的排卵恢复时间中位数分别为 59d、50 d和 3 6 d(P<0 .0 0 1 ) ,提示母乳喂养可在一定程度上推迟排卵。研究发现 ,身高体重指数(BMI)≥ 2 4的体型较肥胖者 ,其排卵恢复时间长于 BMI<2 4者 (P<0 .0 1 ) ;初潮年龄 >1 5岁者排卵恢复时间长于初潮年龄 <1 5岁者 (P<0 .0 5) ;产妇营养较好者排卵恢复时间比一般营养者短 (P<0 .0 1 ) ;年龄、职业、文化程度对排卵恢复时间也有一定的影响。本研究还用多因素比例风险模型 ,分析了部分影响因素在不同时期对排卵的影响。The recovery days of ovulation in 1 000 postpartum women were observed in this study.B type ultrasonic scanning and urinary LH assay were used for determination of ovulation.The fiftieth percentile of first ovulation is 56 days and the recovery day ranged from 14 to 537 days.The medium day of ovulation in breast feeding,mix feeding and artificial feeding were 59,50 and 36 days respectively (P<0.05).The recovery days is longer in women with BMI≥24 than those with BMI<24. The recovery days in women whose age of menarche are younger than 15 were distinctly shorter than that of the women with menarche later than 15 years of age.For women with better nutrition,the recovery days are shorter than that of the women with nutrition in general level.The research also found that age,occupation and education of postpartum women have definite influences on the recovery days of ovulation.COX model was used for analyzing some risk factors that influenced on the recovery days of ovulation after parturition.
