摘要： 目的 调查重庆市婴幼儿母乳喂养现状,并探讨其影响因素。方法 根据地域差异和经济情况,采用目的性抽样选取重庆市主城4个区和2个周边区县共633名0~36月龄婴幼儿的母亲为研究对象。调查数据录入Epi Data 3.1数据库,采用SPSS 18.0 软件进行统计描述和分析,并运用单因素和多因素logistic回归法分析婴儿4月龄内纯母乳喂养的影响因素。结果 被调查地区婴儿4月龄内纯母乳喂养率为58.5%。多因素分析结果显示,同伴喂养方式为纯母乳喂养、自觉母乳量能满足婴儿、对母乳喂养有信心是纯母乳喂养的有利因素;介意公共场所母乳喂养是纯母乳喂养的不利因素。结论 被调查地区婴儿4月龄内纯母乳喂养率有待提高,亟待采取有针对性的干预措施。
