Bangladesh is undergoing a rapid urbanization process. About one-third of the population of major cities in the country live in slums, which are areas that exhibit pronounced concentrations of factors that negatively affect health and nutrition. People living in slums face greater challenge to improve their health than other parts of the country, which fuels the growing intra-urban health inequities. Two rounds of the Bangladesh Urban Health Survey (UHS), conducted in 2013 and 2006, were designed to examine the reproductive health status and service utilization between slum and non-slum residents. We applied an adaptation of the difference-in-differences (DID) model to pooled data from the 2006 and 2013 UHS rounds to examine changes over time in intra-urban differences between slums and non-slums in key health outcomes and service utilization and to identify the factors associated with the reduction in intra-urban gaps. In terms of change in intra-urban differentials during 2006-2013, DID regression analysis estimated that the gap between slums and non-slums for skilled birth attendant (SBA) during delivery significantly decreased. DID regression analysis also estimated that the gap between slums and non-slums for use of modern contraceptives among currently married women also narrowed significantly, and the gap reversed in favor of slums. However, the DID estimates indicate a small but not statistically significant reduction in the gap between slums and non-slums for child nutritional status. Results from extended DID regression model indicate that availability of community health workers in urban areas appears to have played a significant role in reducing the gap in SBA. The urban population in Bangladesh is expected to grow rapidly in the coming decades. Wide disparities between urban slums and non-slums can potentially push country performance off track during the post-2015 era, unless the specific health needs of the expanding slum communities are addressed. To our knowledge, this is the first systematic explanation and quantification of the role of various factors for improving intra-urban health equity in Bangladesh using nationally representative data. The findings provide a strong rationale for continuing and expanding community-based reproductive health services in urban areas by the NGOs with a focus on slum populations.
孟加拉国正在经历快速的城市化进程。该国主要城市约有三分之一的人口居住在贫民窟,这些地区存在着明显的影响健康和营养的因素集中。与该国其他地区相比,生活在贫民窟的人们在改善健康方面面临更大的挑战,这加剧了城市内部的健康不平等。两轮孟加拉国城市健康调查(UHS)于 2013 年和 2006 年进行,旨在检查贫民窟和非贫民窟居民的生殖健康状况和服务利用情况。我们应用差异中的差异(DID)模型的改编版,对 2006 年和 2013 年两轮 UHS 的汇总数据进行分析,以检验关键健康结果和服务利用方面城市内部差异随时间的变化,并确定与缩小城市内部差距相关的因素。就 2006-2013 年期间城市内部差异的变化而言,DID 回归分析估计,分娩时熟练接生员(SBA)方面的贫民窟和非贫民窟之间的差距显著缩小。DID 回归分析还估计,目前已婚妇女中使用现代避孕药具方面的贫民窟和非贫民窟之间的差距也明显缩小,而且有利于贫民窟。然而,DID 估计表明,贫民窟和非贫民窟之间儿童营养状况的差距略有缩小,但无统计学意义。扩展的 DID 回归模型的结果表明,城市地区社区卫生工作者的可用性似乎在缩小 SBA 差距方面发挥了重要作用。孟加拉国的城市人口预计在未来几十年将迅速增长。如果不解决不断扩大的贫民窟社区的具体健康需求,城市贫民窟和非贫民窟之间的巨大差距可能会使该国在 2015 年后的表现偏离轨道。据我们所知,这是首次使用全国代表性数据系统地解释和量化各种因素在改善孟加拉国城市内部健康公平方面的作用。这些发现为非政府组织继续和扩大以贫民窟人口为重点的城市社区生殖健康服务提供了强有力的理由。
