To investigate and compare the main determinants of overall inequality and wealth-related inequality in under-5 mortality in 13 African countries.
Data from Demographic and Health Surveys conducted in 2007-2010 in African countries were used. The study assessed the contribution of determinants to (1) overall inequality in under-5 mortality measured by the Gini index and (2) wealth-related inequality in under-5 mortality measured by the concentration index. Techniques used were multivariate logistic regression and decomposition of Gini and concentration indexes.
Birth order and interval and region contributed the most to overall inequality in under-5 mortality in a majority of countries. A significant wealth-related inequality was observed in five countries: DRCongo, Egypt, Madagascar, Nigeria and Sao Tome & Principe. Overall, household wealth, father's occupation and mother's education contributed the most to this inequality, though the ranking of the most important determinants differed across countries.
Assessing the contribution of determinants to overall inequality and to wealth-related inequality in under-5 mortality help in prioritising interventions aiming at improving child survival and equity.
调查和比较 13 个非洲国家五岁以下儿童死亡率总不平等和与财富相关不平等的主要决定因素。
使用了 2007-2010 年在非洲国家进行的人口与健康调查的数据。本研究评估了决定因素对（1）用基尼指数衡量的五岁以下儿童死亡率总不平等和（2）用集中指数衡量的与财富相关的五岁以下儿童死亡率不平等的贡献。采用的技术包括多变量逻辑回归和基尼和集中指数的分解。
出生顺序和间隔以及地区对大多数国家五岁以下儿童死亡率总不平等的贡献最大。在五个国家观察到与财富相关的不平等：刚果民主共和国、埃及、马达加斯加、尼日利亚和圣多美和普林西比。总的来说，家庭财富、父亲的职业和母亲的教育对这种不平等的贡献最大，尽管各国最重要的决定因素的排名有所不同。
评估决定因素对五岁以下儿童死亡率总不平等和与财富相关不平等的贡献有助于确定旨在改善儿童生存和公平的干预措施的优先次序。
