摘要

目的

分析重庆市2010-2020年剖宫产率现状及其影响因素。

方法

采用全面调查的方法，利用2010-2020年《重庆市产科质量调查表》以及出生医学证明数据，以全市提供助产服务的医疗卫生机构为研究对象，进行产妇分娩方式选择情况及其影响因素的现况调查。

结果

2020年全市剖宫产率为47.59%，较2019年小幅上升0.15%；首次剖宫产率43.30%，较2019年上升2.29%；非医学指征剖宫产比例为13.20%，较2019年上升19.03%。全市35岁及以上产妇剖宫产率65.85%，远高于18岁以下产妇剖宫产率(25.91%)及18~34岁产妇剖宫产率(45.61%)。全市民营医疗机构剖宫产率为51.83%，高于公立一级医疗机构(31.69%)、二级医疗机构(46.11%)、三级医疗机构(50.50%)以及厂矿医疗机构(44.75%)剖宫产率。2020年，全市有医学指征的剖宫产中，因瘢痕子宫剖宫产的比例最高(45.57%)，其次为高龄产妇(9.73%)、胎儿窘迫(8.78%)、妊娠巨大儿(6.67%)、胎位异常(6.43%)。

结论

瘢痕子宫、高龄产妇(年龄≥35岁)、妊娠期严重合并症和并发症、妊娠巨大儿、胎儿窘迫等因素均在剖宫产指征中占有较大比例，严重影响全市剖宫产率的控制。民营机构剖宫产率、首次分娩剖宫产率以及非医学指征剖宫产比例均远高于其他类别助产机构。
