目的:了解四川省农村孕妇孕前预防出生缺陷的行为现状,为不同地区出生缺陷一级预防行为等级划分提供统计学方法参考。方法:利用四川省出生缺陷项目问卷中的服务对象层数据,描述四川省孕妇的基本情况和出生缺陷一级预防行为现状;利用TOPSIS和RSR法对四川省多个地区的出生缺陷一级预防行为进行综合评价。结果:选取的四川省8个地区的917位农村孕妇,婚检率49.18%,孕检率和叶酸服用率均超过80%。没有婚检的主要原因是认为自己健康,没有孕检的主要原因是意外怀孕,没有合理增补叶酸的主要原因是不知道叶酸好处。将婚检率、孕检率、叶酸服用率、风险预防情况作为评价指标进行综合评价后,射洪、夹江和龙泉在农村地区表现较好。结论:调查中8个地区的婚检率显著高于全省平均水平,但是各个地区的婚检率相差较大,应该加强健康教育,提高孕前优生知识水平,进而改善出生缺陷一级预防的行为。 OBJECTIVE: To understand the status quo of pregnant women in Sichuan Province before pregnancy to prevent birth defects, and to provide a statistical reference for the classification of primary prevention of birth defects in different areas.
