背景技术背景：儿童生命早期阶段的营养状况不仅对婴儿期而且对成年期的生长和发育至关重要。本研究旨在衡量在伊朗的五岁以下儿童营养不良的不平等，并探讨社会经济因素对这种不平等的影响，使用基于回归的分解approach.METHODS：数据提取自伊朗的多指标人口与健康调查2010年。采用发育迟缓、体重不足和消瘦的集中指数来衡量儿童营养不良方面的社会经济不平等程度。此外，浓度指数进行分解，以了解社会经济变量在儿童营养不良inequality.Results的贡献：得到的浓度指数的发育迟缓，体重不足，消瘦分别为-0.177，-0.092，-0.031。在发育迟缓和体重不足方面的社会经济不平等在统计上是显著的，但在消瘦方面没有观察到这种社会经济梯度。超过50%的发育迟缓不平等和约63%的体重不足不平等受到社会经济地位的影响。此外，孕产妇教育与19%和22%的不平等，发育迟缓和体重不足respectively.CONCLUSION：平均减少营养不良指数在国家一级隐藏的负担，在贫困家庭的儿童营养不良。如果政府和决策者寻求解决这一问题，他们必须采取直接和有针对性的行动，消除与营养不良有关的社会经济决定因素中现有的不平等。
BACKGROUND: Nutritional status at the early stages of children's lives is essential for growth and development not only in infancy but also in adult life. This study aimed to measure the inequality in malnutrition among under-five children in Iran and explore the impact of socioeconomic factors on this inequality using a regression-based decomposition approach.METHODS: Data were extracted from Iran's Multiple-Indicator Demographic and Health Survey 2010. The concentration index of stunting, underweight, and wasting were applied in order to measure the magnitude of socioeconomic inequality in child malnutrition. Moreover, the concentration indices were decomposed to understand the contribution of socioeconomic variables in childhood malnutrition inequality.RESULTS: The obtained concentration indices of stunting, underweight, and wasting were respectively -0.177, -0.092, and -0.031. Socioeconomic inequality in stunting and underweight was statistically significant, however this socioeconomic gradient was not observed in wasting. More than 50% of the inequality in stunting and about 63% of the inequality in underweight were influenced by socioeconomic status. Furthermore, maternal education was associated with 19% and 22% of inequality in stunting and underweight respectively.CONCLUSION: The average reduction of malnutrition indices at the national level hides the burden of malnutrition among children in poor families. If government and policymakers seek to solve this problem, they have to take direct and targeted actions to eliminate the existing inequalities in the socioeconomic determinants associated with malnutrition.
