Few previous studies have examined non-wealth-based inequalities in child mortality within developing countries. This study estimates changes in under-5-year-olds and neonatal mortality in Nepal across a range of subnational levels, which allows us to assess the degree of equity in Nepal's progress towards Millennium Development Goal 4.
Direct estimates of under-5-year-olds and neonatal death rates were generated for 1990-2005 using three Demographic and Health Surveys and two Living Standards Surveys by the following levels: national, rural/urban location, ecological region, development region, ethnicity and wealth. Absolute and relative inequalities were measured by rate differences and rate ratios, respectively. Additionally, wealth-related inequality was calculated using slope and relative indexes of inequality and concentration indices.
Estimates suggest that while most rates of under-5-year-olds and neonatal mortality have declined across the different equity markers, leading to a downward trend in absolute inequalities, relative inequalities appear to have remained stable over time. The decline in absolute inequalities is strongest for under-5-year-olds' mortality, with no statistically significant trend in either relative or absolute inequalities found for neonatal mortality. A possible increase in inequalities, at least in relative terms, was found across development regions, where death rates remain high in the mid-western region.
By 2015, our estimates suggest that more than 65% of deaths of under-5-year-olds will occur in the neonatal period, with stable trends in neonatal mortality inequalities. These findings along with the fact that health outcomes for neonates are more highly dependent on health systems, suggest further equitable reductions in under-5-year-olds mortality will require broad health-system strengthening, with a focus on the improvement of healthcare services provided for mothers and newborns. Other inequities suggest continued special attention for vulnerable subpopulations is warranted, particularly to overcome social exclusion and financial barriers to care in urban areas.
之前的研究很少关注发展中国家内部非财富相关的儿童死亡率不平等问题。本研究在一系列次国家级水平上估计了尼泊尔五岁以下儿童和新生儿死亡率的变化,这使我们能够评估尼泊尔在实现千年发展目标 4 方面取得的进展的公平程度。
使用三次人口与健康调查和两次生活水平调查,在以下水平上生成了 1990 年至 2005 年五岁以下儿童和新生儿死亡率的直接估计值:国家、农村/城市位置、生态区、发展区、族裔和财富。分别使用率差异和率比来衡量绝对和相对不平等。此外,还使用斜率和不平等的相对指数以及集中指数来计算与财富相关的不平等。
研究结果表明,尽管在不同的公平指标下,大多数五岁以下儿童和新生儿死亡率都有所下降,导致绝对不平等呈下降趋势,但相对不平等似乎随着时间的推移保持稳定。五岁以下儿童死亡率的绝对不平等下降幅度最大,而新生儿死亡率的相对或绝对不平等则没有明显的趋势。在发展区域内发现了不平等程度的可能增加,至少在相对方面,在中西部地区死亡率仍然很高。
根据我们的估计,到 2015 年,超过 65%的五岁以下儿童死亡将发生在新生儿期,新生儿死亡率的不平等趋势保持稳定。这些发现以及新生儿健康结果更依赖于卫生系统的事实表明,要进一步公平地降低五岁以下儿童的死亡率,需要广泛加强卫生系统,重点是改善为母亲和新生儿提供的医疗保健服务。其他不平等现象表明,有必要继续特别关注弱势群体,特别是要克服城市地区社会排斥和获得医疗保健的经济障碍。
