背景:撒哈拉以南非洲(SSA)一半以上的人口面临获得安全饮用水的机会有限。水源未得到改善会对整个家庭的健康构成风险,特别是妇女和儿童。尽管东非国家拥有一些全球最贫穷的饮用水基础设施,缺乏关于这个问题的公开数据。因此,这项研究的目的是研究东非家庭获得安全饮用水及其决定因素,利用最近的全国代表性数据。
方法:本研究分析了2011年至2022年在12个东非国家进行的近期人口和健康调查的数据。数据来自204,275户家庭。采用分层两阶段整群抽样方法,以列举区为主要抽样单位,以住户为二次抽样单位。采用二元和多元多水平logistic回归分析该地区不同饮用水源使用的相关因素。在二元回归和多元回归中,P值分别≤0.2和<0.05,用于确定最终模型中变量的统计显著性。
结果:大约72.62%(95%CI=72.43,72.83)的家庭使用了改善的饮用水源。25-35岁的户主(AOR=1.09,95%CI=1.04,1.14),36-45岁(AOR=1.09,95%CI=1.04,1.14),和>45年(AOR=1.08,95%CI=1.04,1.14),中等/高等教育者(AOR=1.24,95%CI=1.20-1.29),和财富指数类别中最贫穷的个人(AOR=0.17,95%CI=0.16,0.18),较差(AOR=0.21,95%CI=0.19,0.22),中等(AOR=0.25,95%CI=0.24,0.27),和更丰富(AOR=0.36,95%CI=0.34,0.38)与饮用水源的改善有关。此外,女性户主(AOR=1.23,95%CI=1.20,1.26),进入水源的时间>30分钟(AOR=2.00,95%CI=1.95,2.05),改善厕所设施(AOR=2.25,95%CI=2.19,2.31),农村住宅(AOR=0.43,95%CI=0.42,0.45),高社区财富(AOR=1.31,95%CI=1.13-1.51),社区媒体暴露(AOR=1.32,95%CI=1.15,1.51)与改善饮用水源相关,分别。
结论:东非大约四分之三的人口获得了改善的饮用水,尽管该地区的水质仍然被认为是差的。重要的是相关组织要合作,以提高饮用水的质量,特别关注高风险群体,例如高贫困和低识字率的社区,贫困家庭,和农村居民。加强妇女赋权和增加大众媒体的曝光率也可以在加快东非改善饮用水源的采用方面发挥关键作用。
BACKGROUND: More than half of the population in Sub-Saharan Africa (SSA) faces limited access to safe drinking water. Unimproved water sources can pose risks to the health of entire households, particularly women and children. Despite the fact that East African countries have some of the poorest drinking water infrastructures globally, there is a lack of published data on this issue. Consequently, the objective of this study was to examine access to safe drinking water and its determinants among households in East Africa, utilizing recent nationally representative data.
METHODS: This study analyzed data from recent demographic and health surveys conducted in 12 East African nations between 2011 and 2022. Data were gathered from 204,275 households. A stratified two-stage cluster sampling method was employed, with enumeration areas serving as the main sampling units and households serving as the secondary sampling units. Binary and multiple multilevel logistic regression were used to examine the relevant factors associated with the use of different sources of drinking water in the region. In binary regression and multiple regression, P values of ≤ 0.2 and < 0.05, respectively, were used to determine the statistical significance of variables in the final model.
RESULTS: Approximately 72.62% (95% CI = 72.43, 72.83) of households have utilized improved sources of drinking water. Household heads aged 25-35 years (AOR = 1.09, 95% CI = 1.04, 1.14), 36-45 years (AOR = 1.09, 95% CI = 1.04, 1.14), and > 45 years (AOR = 1.08, 95% CI = 1.04, 1.14), those with secondary/higher education (AOR = 1.24, 95% CI = 1.20-1.29), and individuals in wealth index categories of poorest (AOR = 0.17, 95% CI = 0.16, 0.18), poorer (AOR = 0.21, 95% CI = 0.19, 0.22), middle (AOR = 0.25, 95% CI = 0.24, 0.27), and richer (AOR = 0.36, 95% CI = 0.34, 0.38) were associated with improved sources of drinking water. Additionally, female household leaders (AOR = 1.23, 95% CI = 1.20, 1.26), > 30 min of time taken to access the water source (AOR = 2.00, 95% CI = 1.95, 2.05), improved toilet facilities (AOR = 2.25, 95% CI = 2.19, 2.31), rural residence (AOR = 0.43, 95% CI = 0.42, 0.45), high community wealth (AOR = 1.31, 95% CI = 1.13-1.51), community media exposure (AOR = 1.32, 95% CI = 1.15, 1.51) were associated with improved sources of drinking water, respectively.
CONCLUSIONS: Approximately three-quarters of the population in East Africa has access to improved drinking water, although the quality of water in the region is still considered poor. It is important for relevant organizations to collaborate in order to improve the quality of drinking water, with special attention given to high-risk groups such as communities with high poverty and low literacy rates, poor households, and rural residents. Strengthening women\'s empowerment and increasing mass media exposure can also play a crucial role in accelerating the adoption of improved drinking water sources in East Africa.
