目的：探讨我国部分地区规范产前检查情况及其与早产儿发生的关系。方法对辽宁省两县区和四川省两县区产妇的产前检查情况及早产儿发生情况进行回顾性分析,并对数据进行统计。结果在7171名研究对象中,产检次数在5次以上的孕妇比例为88.6%,进行规范产检的孕妇比例为28.9%。早产儿发生率为4.0%,规范产检组早产儿发生率低于非规范产检组(χ2=0.015,P=0.015)。经单因素和多因素Logistic回归显示,进行规范的产检是早产儿发生的保护因素( OR=0.534,P=0.016；OR=0.631,P=0.003)。结论孕妇孕期产前检查规范性有待提高。规范的产前检查是早产儿发生的保护因素。%Objective To explore the situation of normative antenatal care in some regions in China and its relationship with preterm birth. Methods A retrospective study was conducted for the situation of antenatal care and preterm birth in 4 counties and districts from Sichuan and Liaoning province, and the data were statistically analyzed. Results Information from 7 171 pregnant women showed that 88. 6% of them accepted antenatal care at least 5 times and 28. 9% of them accepted normative antenatal care. The incidence of preterm birth was 4. 0%, and that in the normative antenatal care group was lower (χ2 =0. 015,P=0. 015). Univariate and multivariate Logistic regression analysis showed that normative antenatal care was a protective factor of preterm birth (OR=0. 534,P=0. 016,OR=0. 631,P=0. 003). Conclusion The normative degree of antenatal care is needed to be improved. The normative antenatal care is a protective factor of preterm birth.
