采用分层、系统和整群抽样相结合的多阶段抽样方法,对江苏省无锡市2002-2004年孕产妇及其孕28周以上的胎婴儿作了调查。采用问卷调查的方式对1628名调查对象进行了面访。调查地区属于较发达的地区,但孕前去过卫生服务机构进行出生缺陷预防保健知识咨询的孕妇并不多,且能够在怀孕后早期到医院进行检查的比例更低。为有效预防出生缺陷的发生,需要探索一种更为有效的模式,提高孕产妇对预防保健服务的利用。
A multi-stage sampling method combining stratification, systematic and cluster sampling was used to investigate the pregnant women and fetus infants born more than 28 weeks from 2002 to 2004 in Wuxi, Jiangsu Province. A questionnaire survey was conducted on 1628 interviewees. The surveyed areas belonged to the more developed regions, but not many pregnant women who had been to health service agencies before their pregnancy to get knowledge of birth defect prevention and health care and had a lower rate of going to the hospital in early pregnancy. In order to effectively prevent birth defects, we need to explore a more effective model to improve the utilization of preventive health services by pregnant women.
