摘要： 目的 系统评价影响我国母乳喂养持续时间的相关因素,为相关研究和干预提供借鉴。方法 计算机检索Web of Science、PubMed、EMBASE、Cochrane、维普、中国知网、万方和中国生物医学文献数据库,收集影响我国母乳喂养持续时间相关因素的文献。两名研究者对文献进行质量评价和资料提取,进行系统评价。结果 共纳入17篇文献,分析结果显示,保护因素包括婴儿顺利吸食母乳、较长时间产假、母亲对合理母乳喂养时间的认可、坚持纯母乳喂养至6个月等;危险因素包括早产、剖宫产、半岁内添加辅食或牛羊奶、预计母乳喂养时间较短、泌乳Ⅱ期延迟、父亲吸烟、母亲对母乳喂养的认知程度较低等。分类为儿童基本特征、母亲基本特征、家庭社会经济环境等客观因素和母乳喂养的态度观念等因素。结论 我国母乳喂养持续时间影响因素很多,部分因素的作用仍有不同评价,相关因素与母乳喂养持续时间的因果关系有待进一步验证。
