Malnutrition among children is a significant public health and development issue, especially in low- and middle-income countries, Malawi inclusive, which contributes to preventable diseases and deaths. Significant socioeconomic disparities persist, which affect access to and equal distribution of basic nutrition. This study analyzed the extent and trends of Inequality of Opportunity (IOP) in the nutritional outcomes of children aged 0-59 months.
The study used nationally representative data from the 2006, 2013-14, and 2019-20 Malawi Multiple Indicator Cluster Survey. In terms of method, we examined IOP in stunting, wasting, and underweight indicators, using the Human Opportunity Index and the Dissimilarity Index in 55,723 children. The Shapley-value technique decomposed the relative IOP.
We find the largest share of circumstance-driven inequality in stunting (8.96 percent), followed by underweight (1.91 percent), and then wasting (0.90 percent). The Shapley-value decomposition results indicate the child's age (29.15 percent for stunting, 12.42 percent for underweight, and 52.36 percent for wasting) and gender (8.28 percent, 18.36 percent and 8.87 percent), wealth (6.36 percent, 22.87 percent and 8.54 percent), and mother's education (6.28 percent, 11.29 percent and 5.51 percent) as the dominant contributors to IOP for all three nutritional outcome indicators; stunting, underweight and wasting, respectively.
The findings suggest that policies aimed at narrowing the wealth and education inequality gap could help equalize nutrition opportunities for children in Malawi.
儿童营养不良是一个重大的公共卫生和发展问题,尤其是在包括马拉维在内的低收入和中等收入国家,它会导致可预防的疾病和死亡。严重的社会经济差距依然存在,这影响了基本营养的获取和平等分配。本研究分析了0至59个月儿童营养结果中机会不平等(IOP)的程度和趋势。
该研究使用了2006年、2013 - 14年和2019 - 20年马拉维多指标类集调查的全国代表性数据。在方法上,我们使用人类机会指数和差异指数,对55723名儿童的发育迟缓、消瘦和体重不足指标中的IOP进行了研究。夏普利值技术分解了相对IOP。
我们发现,发育迟缓中由环境驱动的不平等占比最大(8.96%),其次是体重不足(1.91%),然后是消瘦(0.90%)。夏普利值分解结果表明,儿童的年龄(发育迟缓为29.15%,体重不足为12.42%,消瘦为52.36%)、性别(分别为8.28%、18.36%和8.87%)、财富(分别为6.36%
