A nation-wide perinatal census which included 22,815 deliveries was carried out. The cesarean section rate was 9.6% and the perinatal mortality rate was 13.5/1000. Using a logistic regression analysis the risk factors for cesarean section and for perinatal mortality were ranked. Breech presentation and one uterine scar were found to be the most important risk factors for cesarean section and breech presentation, maternal disease and multiple pregnancy for perinatal mortality. Low birth weight rate was 6.9% with nonsignificant differences between the various ethnic groups. The national cesarean section rate in breech presentation was 57.8%. It was performed mainly at the extremes of birth weight. From those with one previous cesarean section 55.1% delivered vaginally and 44.9% abdominally. The chance for vaginal delivery is higher (67.2%) providing the woman had delivered vaginally in the past. Comparison between primiparae and multiparae showed that preeclampsia, hypertension and diabetes mellitus were all significantly more frequent among older parturients and among primiparae.
开展了一项涵盖22815例分娩的全国围产期普查。剖宫产率为9.6%，围产儿死亡率为13.5‰。通过逻辑回归分析对剖宫产和围产儿死亡的危险因素进行了排序。臀位和有一次子宫瘢痕被发现是剖宫产最重要的危险因素，而臀位、母体疾病和多胎妊娠是围产儿死亡的危险因素。低出生体重率为6.9%，各民族之间无显著差异。全国臀位剖宫产率为57.8%。主要在出生体重极值时进行。有过一次剖宫产史的产妇中，55.1%经阴道分娩，44.9%经腹分娩。如果该女性过去曾经阴道分娩，那么经阴道分娩的几率更高（67.2%）。初产妇与经产妇的比较表明，子痫前期、高血压和糖尿病在高龄产妇和初产妇中均更为常见。
