Abstract
Diarrhea is a leading cause of mortality in children under 5 years of age. We conducted a cross-sectional study of 54 children aged 3 months to 5 years old in Kibera, an urban slum in Nairobi, Kenya, to assess the relationship between caregiver-reported soil ingestion and child diarrhea. Diarrhea was significantly associated with soil ingestion (adjusted odds ratio = 9.9, 95% confidence interval = 2.1-47.5). Soil samples from locations near each household were also collected and analyzed for and a human-associated fecal marker (HF183). was detected in 100% of soil samples (mean 5.5 log colony forming units per gram of dry soil) and the fecal marker HF183 was detected in 93% of soil samples. These findings suggest that soil ingestion may be an important transmission pathway for diarrheal disease in urban slum settings.
摘要
腹泻是5岁以下儿童死亡的主要原因。我们对肯尼亚内罗毕一个城市贫民窟基贝拉的54名3个月至5岁儿童进行了一项横断面研究，以评估照顾者报告的土壤摄入与儿童腹泻之间的关系。腹泻与土壤摄入显著相关（调整后的优势比=9.9，95%置信区间=2.1-47.5）。还收集了每户附近地点的土壤样本，并分析了[具体物质]和一种人类相关的粪便标志物（HF183）。100%的土壤样本中检测到了[具体物质]（每克干土平均5.5个对数菌落形成单位），93%的土壤样本中检测到了粪便标志物HF183。这些发现表明，在城市贫民窟环境中，土壤摄入可能是腹泻疾病的一个重要传播途径。
