摘　　要：目的了解中国4省监测地区婴儿首次添加辅食时间现状,探讨影响辅食添加时间的因素。方法选取2015年9月至2019年6月中国疾病预防控制中心妇幼保健中心开展的母婴健康动态追踪监测项目中4省5个监测点共2367例婴儿,进行随访数据收集。采用χ2检验对监测地区婴儿首次添加辅食时间(≤4、5、6、7、≥8月龄)分布特征进行比较,采用二分类logistic回归模型分析监测地区婴儿首次添加辅食时间的影响因素。结果中国4省监测地区婴儿首次添加辅食时间≤4、5、6、7、≥8月龄分别占16.35%、50.61%、23.91%、5.83%、3.30%。logistic回归分析结果显示,相比于母乳喂养时长<6个月、母亲打算开始添加辅食的时间<6月龄的婴儿,母乳喂养时长≥6个月、母亲打算开始添加辅食的时间≥6月龄的婴儿较早开始添加辅食的可能性更小(OR=0.407,95%CI:0.307~0.539;OR=0.625,95%CI:0.496~0.787)。相比于分娩方式为阴道/自然助产,母亲分娩方式为剖宫产的婴儿较早开始添加辅食的可能性更大(OR=1.269,95%CI:1.012~1.592)。结论母乳喂养时长、母亲分娩方式、母亲打算开始添加辅食的时间是婴儿首次添加辅食时间独立影响因素。应针对性地加强对重点地区有关辅食添加的宣传教育和健康指导,以促进适时、科学合理的喂养婴儿。Objective To understand the timing for first introducing complementary food to infants in monitoring sites of four provinces in China,and to analyze the factors that influence the timing of complementary food introduction.Methods A total of 2367 infants from five monitoring sites in four provinces were selected from the maternal and child health monitoring project conducted by National Center for Women and Children's Health,China CDC from September 2015 to June 2019.The chi-square test was used to analyze the distribution characteristics of first introducing time of complementary food(≤4,5,6,7,≥8 months),and binary logistic regression analysis was used to analyze the influencing factors.Results The percentage of first introducing time of complementary food(≤4,5,6,7,≥8 months)in infants in monitoring sites were 16.35%,50.61%,23.91%,5.83%and 3.30%,respectively.The logistic regression analysis results showed that compared to infants who were breastfed for less than 6 months and whose mothers planned to start complementary foods before 6 months of age,infants who were breastfed for 6 months or more and whose mothers planned to start complementary foods after 6 months of age were less likely to start complementary foods early(OR=0.407,95%CI:0.307-0.539;OR=0.625,95%CI:0.496-0.787).Compared to infants delivered vaginally/naturally,infants delivered by cesarean section were more likely to start complementary foods early(OR=1.269,95%CI:1.012-1.592).Conclusion The duration of breastfeeding,mode of delivery,and maternal intention to start complementary foods independently influence the timing of complementary food introduction in infants.Targeted promotion and education on complementary food addition should be strengthened in key areas to promote timely and scientifically reasonable infant feeding Study.
