【摘要】 [目的]描述北京市流动孕妇的营养知识、态度及饮食行为(KAP)现状,探讨其影响因素,为城市流动孕妇营养保健工作提供科学依据。[方法]采用问卷调查法对北京市近郊区150名流动孕妇和150名户籍孕妇进行调查。[结果]流动孕妇的营养KAP水平较差,总分合格率为52.32%,其中营养知识知晓及格率仅为27.15%。流动孕妇在"钙的最佳食物来源"和"孕期为什么补充叶酸"等知识上低于户籍孕妇,差异有统计学意义,营养态度普遍较好,对孕妇和胎儿健康特别重要的畜禽肉类、蛋类、水产品类、奶类、豆类及坚果、动物内脏和血摄入频率不足,尤其是蛋类明显低于户籍孕妇;对流动孕妇的营养K、A、P之间进行相关性分析发现,K、A、P之间具有明显相关性,K-A相关系数为0.4;K-P相关系数为0.3,A-P相关系数为0.2。孕妇营养KAP水平主要受孕妇学历的影响,偏回归系数β值为3.6。孕妇获得营养知识的主要途径是网络。[结论]目前北京市流动孕妇的营养知识和饮食行为仍存在一定问题,应加强对流动孕妇进行营养知识和孕期正确生活方式的宣传及指导。更多还原
