Environmental Enteropathy is an inflammatory condition of the gut that leads to intestinal barrier dysfunction. It is a common problem in resource-limited countries and results from exposure to larger quantities of fecal bacteria to poor personal hygiene and environmental sanitation. Due to poor intestinal permeability, there is a problem with absorption of nutrients, which in turn leads to growth faltering, poor cognitive development, and oral-vaccine failure. The aim of this study was to identify the children with an elevated lactulose to mannitol ratio (indicative of possible environmental enteropathy) and its association with water sanitation and hygiene in slum areas of Jimma Town so as to mitigate the problem of malnutrition in under-five children.
A community-based cross-sectional study was carried out from January to April 2021. A Lactulose mannitol test was performed to determine the prevalence of elevated lactulose to mannitol ratio (possibly environmental enteropathy) in children aged 12 to 59 months. A pretested questionnaire was used to collect data on water sanitation and hygiene (WASH) indicators and sociodemographic characteristics. A multivariable logistic regression analysis was used to isolate independent predictors for possible environmental enteropathy. All tests were two-sided and statistical significance was declared at P<0.05.
The results of this study showed that 19.3% (95%CI: 14.8-23.7) of children had an increased lactulose to mannitol ratio (>0.15). On multivariable logistic regression analysis, the variables drinking water from unimproved water sources (AOR 3.741; 95%CI: 0.914-15.310,p = 0.048), unsafe coverage of water storage (AOR 0.363; 95%CI: 0.169-0.777, P = 0.009), public latrine utilization (AOR 0.139 95%CI: 0.024-0.816, P = 0.029),and hand washing less than 3 critical time of hand washing practices (AOR 4.369;95%CI: 1.411-13.524,P = 0.011) were significantly associated with an increased in lactulose mannitol ratio (possible indicative of intestinal permeability/environmental enteropathy).
This study showed that one fifth of under-five children in Jimma Town had an elevated lactulose to mannitol ratio (possibly environmental enteropathy). The WASH sectors and other governmental organizations should give emphasis to areas with poor water sanitation and hygiene to mitigate the problem of environmental enteropathy and related consequences like growth faltering, poor cognitive development, and oral-vaccine failure in the study area.
肠黏膜通透性增加导致的肠黏膜炎症,即环境相关性肠病,是资源有限国家中常见的问题。其病因与较差的个人卫生和环境卫生条件下摄入更多的粪便细菌有关。由于肠黏膜通透性增加,导致营养物质吸收不良,进而导致生长发育迟缓、认知能力差和口服疫苗失败。本研究旨在确定吉姆马镇贫民窟儿童中可能存在的乳果糖/甘露醇比值升高(提示环境相关性肠病)及其与水卫生和环境卫生之间的关联,以便减轻五岁以下儿童的营养不良问题。
本研究是一项基于社区的横断面研究,于 2021 年 1 月至 4 月进行。采用乳果糖/甘露醇试验确定 12 至 59 个月龄儿童中乳果糖/甘露醇比值升高(可能存在环境相关性肠病)的患病率。使用经过预测试的问卷收集水卫生和环境卫生(WASH)指标和社会人口学特征的数据。采用多变量逻辑回归分析确定环境相关性肠病的独立预测因素。所有检验均为双侧检验,P<0.05 为统计学显著性差异。
本研究结果显示,19.3%(95%CI:14.8-23.7)的儿童存在乳果糖/甘露醇比值升高(>0.15)。多变量逻辑回归分析显示,饮用未改良水源的水(AOR 3.741;95%CI:0.914-15.310,p = 0.048)、不安全的储水覆盖(AOR 0.363;95%CI:0.169-0.777,P = 0.009)、使用公共厕所(AOR 0.139 95%CI:0.024-0.816,P = 0.029)和少于 3 次关键洗手时间(AOR 4.369;95%CI:1.411-13.524,P = 0.011)与乳果糖/甘露醇比值升高(可能提示肠黏膜通透性/环境相关性肠病)显著相关。
本研究表明,吉姆马镇五分之一的五岁以下儿童存在乳果糖/甘露醇比值升高(可能存在环境相关性肠病)。WASH 部门和其他政府组织应重视水卫生和环境卫生较差的地区,以减轻环境相关性肠病及其相关后果,如生长发育迟缓、认知能力差和口服疫苗失败。
