目的 降低外来妊娠女工缺陷儿出生率.方法 选择外来女工相对集中的2个社区,其中1个社区516名孕妇为对照组,进行常规的产前系统管理和健康教育;另1个社区504名孕妇为观察组,予以针对性的强化优生教育,包括社区、厂区、院内发放宣传单,播放VCD、电视宣传片,专题讲座等多种形式,以20～30人为小组加强产前检查与管理.结果 观察组对缺陷儿发生原因(除居住环境、营养不良2项外)的知晓率显著高于对照组(均P<0.01),缺陷儿出生率显著低于对照组(P<0.01).结论 强化优生教育能提高流动人口参加产前检查的积极性,提高优生优育意识,从而降低缺陷儿出生率.“,”Objective To reduce rate of birth defects in migrant pregnant women. Methods Two communities were selected, 516 mi-grant pregnant women in 1 community served as control group and were given conventional prenatal management and health educa-tion, and 504 pregnant women in the other community were assigned as observation group and adopted intensive prenatal educa-tion, including dispensing sheets in community, factory and hospital, broadcasting knowledge about prevention of birth defects in VCD and TV, holding lectures etc, and prenatal examination and management was performed in groups with 20-30 pregnancies. Results Awareness rates of factors influencing birth defects (except items of environment and malnutrition) in the observation group were significantly higher than those in the control group, and the rate of birth defects in the observation group was significantly lower(P,(0.01 for all). Conclusion Intensive prenatal edueation can improve compliance with prenatal examination in migrant preg-nancies, improve their awareness of prenatal care, and reduce the rate of birth defects.
