目的：确定孟加拉国5岁以下儿童营养状况的差异在多大程度上可归因于家庭的社会经济地位。设计：营养状况采用年龄比体重（WAZ）、年龄比身高（HAZ）和身高比体重（WHZ）的参考z分数。“拥有分数”是根据拥有收音机、电视、自行车、摩托车和电话以及电力的可用性得出的，分为0到41个类别。使用主成分分析创建了一个五点（五分位数）的“贫困指数”。背景：2004年孟加拉国人口与健康调查是数据来源。对象：5岁以下儿童4891例。结果：约57.8%的样本发育不良、消瘦或体重过轻（7.7%发育不良、消瘦和体重过轻）。在发育不良（48.4%）的儿童中，25.7%的儿童体重过轻。体重不足和消瘦患病率分别为40.7%和14.3%。平均WAZ， HAZ和WHZ没有性别差异。母亲没有受过教育或没有财产的孩子比母亲受过高等教育或拥有4件以上财产的孩子体重不足和发育不良的几率平均高出1个标准差。与贫困指数相比，财产得分对营养不良的歧视程度要大得多。来自无财产家庭的孩子中有近50%发育不良、消瘦或体重不足（在最贫穷的五分之一家庭中只有27%），相比之下，来自拥有4个以上财产家庭的孩子中只有3-6%（在最富有的五分之一家庭中超过13%）。结论：母亲受教育程度和财产得分是儿童营养状况的主要预测因子。占有分数比贫困指数更能反映营养不良。
Objective: To determine how much of the variation in nutritional status of Bangladeshi children under 5 years old can be attributed to the socio-economic status of the family.Design: Nutritional status used reference Z-scores of weight-for-age (WAZ), height-for-age (HAZ) and weight-for-height (WHZ). A 'possession score' was generated based on ownership of a radio, television, bicycle, motorcycle and telephone, and the availability of electricity, with categories of 0 to 41 possessions. A five-point (quintile) 'poverty index' was created using principal component analysis.Setting: The Bangladesh Demographic and Health Survey 2004 was the source of data.Subjects: A sample of 4891 children aged < 5 years was obtained.Results: Some 57.8% of the sample was either stunted, wasted or underweight (7.7% were stunted, wasted and underweight). Of those stunted (48.4%), 25.7% were also underweight. Underweight and wasting prevalences were 40.7% and 14.3%,respectively. Mean WAZ, HAZ and WHZ did not differ by sex. Children of mothers with no education or no possessions were, on average, about 1 SD more underweight and stunted than those with higher educated mothers or with 4+ possessions. The possession score provided much greater discrimination of undernutrition than the poverty index. Nearly 50% of children from households with no possessions were stunted, wasted or underweight (only 27% in the poorest quintile), compared with only 3-6% of children from households with 4+ possessions (over 13% in the richest quintile).Conclusions: Maternal education and possession score were the main predictors of a child's nutritional status. Possession score was a much better indicator of undernutrition than the poverty index.
