目的 了解重庆市彭水县0～2岁婴幼儿喂养现状,探讨其影响因素。方法 采用方便抽样,对重庆市彭水县县城中7个社区及8个乡镇中606名0～2岁婴幼儿的母乳喂养情况和半固体食物引入时间进行问卷调查,调查数据录入Epidata3.1数据库,采用SPSS19.0 软件进行统计分析。结果 4月龄内婴儿纯母乳喂养率为63.6%,6月龄内婴儿纯母乳喂养率为35.3%,63.9%的婴幼儿在出生24 h后开奶。大部分婴幼儿蔬菜、水果、谷类、蛋类、豆类、禽畜类、鱼类添加过晚。多因素Logistic回归分析显示,婴幼儿居住地为乡镇,开奶时间较早,是婴儿4月龄内纯母乳喂养的保护因素;喂养人年龄>40岁,母乳喂养知识得分优秀者,是婴儿4月龄内纯母乳喂养的危险因素。结论 调查地区婴幼儿喂养中开奶不及时,纯母乳喂养率和持续时间有待提高,半固体食物添加月龄不合理,添加过晚现象严重,应向家长提供正确喂养婴幼儿知识指导。
