摘要： 【目的】 分析陕西省镇安县36月龄以下婴幼儿出生情况和喂养行为。 【方法】 采用PPS抽样,在陕西省镇安县抽取432名36月龄以下婴幼儿,进行问卷调查。 【结果】 婴儿平均出生体重为3 270 g,身长50.3 cm,性别间无显著差异。低出生体重儿占5.1%,巨大儿占5.6%。婴儿4个月内母乳喂养率为52.3%。分别有4.2%、 26.3%和73%的婴幼儿在4~5月龄、6~11月龄和12~17月龄断奶。该地区0~5月龄婴儿96.7%已添加汤汁饮料类辅食;开始添加半固体软质谷类食物的中位数大多是在6月龄;有一半婴幼儿在7、8月龄开始添加蛋类和肉类;18~35月龄婴幼儿中有一半是在12个月龄时开始添加鱼类;12~17月龄儿中分别有88.4%和56.5%的比例添加了肉类和鱼类。 【结论】陕西镇安农村婴幼儿母乳喂养率很低,婴儿抱奶时间长,断奶过早,辅食添加过早,6月龄以后辅食种类不丰富,添加优质蛋白的时间较晚。建议应在包括镇安在内的贫困农村加大力度宣传母乳喂养,尽量保证母乳喂养,同时要适时、合理地添加辅食。
