This study examined the underlying demographic and socioeconomic determinants of child nutritional status in Egypt using data from the most recent round of the Demographic and Health Survey. The height-for-age Z-score (HAZ) was used as a measure of child growth. A quantile regression approach was used to allow for a heterogeneous effect of each determinant along different percentiles of the conditional distribution of the HAZ. A nationally representative sample of 13,682 children aged 0-4 years was drawn from the 2014 Egypt DHS. The multivariate analyses included a set of HAZ determinants commonly used in the literature. The conditional and unconditional analyses revealed a socioeconomic gradient in child nutritional status, in which children of low income/education households have a worse HAZ than those from high income/education households. The results also showed significant disparities in child nutritional status by demographic and social characteristics. The quantile regression results showed that the association between the demographic and socioeconomic factors and HAZ differed along the conditional HAZ distribution. Intervention measures need to consider the heterogeneous effect of the determinants of child nutritional status along the different percentiles of the HAZ distribution. There is no one-size-fits-all policy to combat child malnutrition; a multifaceted approach and targeted policy interventions are required to address this problem effectively.
本研究利用最近一轮人口与健康调查的数据,考察了埃及儿童营养状况的潜在人口和社会经济决定因素。身高年龄 Z 分数(HAZ)被用作衡量儿童生长的指标。采用分位数回归方法,允许每个决定因素在 HAZ 条件分布的不同百分位数上产生异质效应。本研究从 2014 年埃及 DHS 中抽取了一个具有全国代表性的 13682 名 0-4 岁儿童样本。多变量分析包括文献中常用的一组 HAZ 决定因素。条件和无条件分析显示,儿童营养状况存在社会经济梯度,低收入/低教育家庭的儿童 HAZ 比高收入/高教育家庭的儿童差。结果还显示,儿童营养状况在人口和社会特征方面存在显著差异。分位数回归结果表明,人口和社会经济因素与 HAZ 之间的关联沿 HAZ 分布的不同百分位数而有所不同。干预措施需要考虑儿童营养状况决定因素在 HAZ 分布不同百分位数上的异质效应。没有一种一刀切的政策可以解决儿童营养不良问题;需要采取多方面的方法和有针对性的政策干预措施,才能有效地解决这一问题。
