目的：研究海口市孕产妇预防出生缺陷知识、态度、行为（KAP）现状及服务利用情况,为构建适宜的出生缺陷区域化预防模式提供科学参考。方法：采用分层与多阶段整群随机抽样方法对海口市2013年12月~2014年12月2 996例孕产妇进行问卷调查。结果：大部分孕产妇对待出生缺陷态度相对积极,67.69%孕产妇孕前及孕早期服用过叶酸;52.20%孕妇接受过婚前医学检查,没做婚前医学检查的主要原因是没必要检查和不知道要检查;45.49%孕妇接受过孕前检查,没有孕前检查的主要原因是意外妊娠;30.11%孕妇接受优生知识相关培训,23.80%孕妇接受遗传咨询;99.60%孕产妇均接受过产前检查,孕后第8周及之前进行第一次检查占36.82%,大部分孕产妇进行第一次产检的时间超过了胎儿致畸敏感期。结论：卫生资源主要集中于城市,农村孕产妇咨询及孕前检查的机会相对较少,要扩展卫生部门保健服务区域,加强资源配置及能力建设,同时亟需提高其预防出生缺陷发生的意识和行为的转变,提高孕妇对出生缺陷预防保健卫生服务的利用,将是海口市出生缺陷预防工作的一个重点。
