摘要
目的了解中国初婚育龄妇女不孕症的省际差异及与各省经济发展的关系。方法基于2001年全国计划生育/生殖健康抽样调查数据和《中国统计年鉴》,共获得符合研究条件的嵌套在30个省级单位内的3 414名育龄妇女样本,利用二层logistic回归模型等进行分析。结果中国不孕率为18.0%(95%CI=16.7%～19.3%),二层logistic回归分析显示,不孕症存在明显的省际差异,省份人均GDP水平与个体不孕风险呈负相关(OR=0.64,P<0.05),而第三产业占GDP比重则与个体不孕风险呈正相关(OR=1.04,P<0.05)。结论中国的不孕症存在省际差异,并与各省经济发展状况相关,其中的作用路径有待进一步研究。
Objective To explore the inter-provincial difference in infertility among women of child-bearing age at the first marriage in China and its relationship to economic development.Methods Using data from the National Family Planning and Reproductive Health Survey in 2001 and from China Statistical Yearbook,we obtained the information of 3 414 child-bearing women from 30 provinces.Two-level logistic regression model was employed in data analyses.Results The national infertility was 18.0%（95% confidence interval：16.7%-19.3%）.The results of regression model showed significant inter-provincial differences.Gross domestic product（GDP） per capita at province level was significantly and inversely associated with individual infertility risk（odds ratio=0.64,P0.05） and the GDP proportion of tertiary sector of industry was positively associated with individual infertility risk（OR=1.04,P0.05）.Conclusion Obvious inter-provincial difference exists and economic development is an important influence factor.However,the pathways need further exploration.
