摘　　要：目的分析广西部分贫困农村2岁以下婴幼儿营养不良现状及其影响因素。方法选择广西4个贫困县作为调查点,采用整群分层抽样法,对每个调查县随机抽取2个乡、每个乡抽取2个村共653名2岁以下婴幼儿作为调查对象。采用WHO/NCHS推荐的性别年龄别身高体重参考值Z评分法,评价儿童营养健康状况,采用多因素非条件Logistic回归模式进行营养不良影响因素分析。结果 653名2岁以下婴幼儿低出生体重率为8.7%,生长迟缓率为39.7%,低体重率为42.1%,消瘦率为14.4%,贫血患病率为25.4%。营养不良多因素非条件Logistic回归分析显示,儿童的年龄、看护人和母亲外出务工时间是婴幼儿生长迟缓、低体重发生的相关影响因素。结论广西部分贫困地区儿童低出生体重发生率明显高于中国2010年控制目标(即小于5%),2岁以下婴幼儿生长迟缓率、低体重率、消瘦发生率和贫血患病率较高。Objective To analyze the prevalence of malnutrition and its affected factors of poor rural infants under 2 years old in Guangxi Province.Methods Applying a three stages stratified cluster sampling method,a total of 653 subjects were sampled from 4 rural poor counties.The Z score standards recommended by NCHS /WHO were used to evaluate the nutrition and health condition of infants.Non-conditional multifactor logistic regression model was used to analyze the factors affecting nutritional status.Results The rates of low birth weight,growth retardation, under weight,emaciation and anemia of 653 infants under 2 years old were 8.7% ,39.7% ,42.1% ,14.4% and 25.4% respectively.The non-conditional multifactor logistic regression model indicates that the age of infants,the caregivers and the time of their mothers working outside were the associated risk factors of growth retardation and under weight of the babies.Conclusion The rate of low birth weight in part of rural poor areas in Guangxi Province was obviously higher than the expecting target （i.e.lower than 5% ） at the year 2010.The rates of growth retardation,under weight,emaciation and anemia were still high.
