This study relies on a comparative assessment of diarrhea occurrence in two urban slums to identify salient factors influencing case prevalence. Primary data were collected from both areas using a structured closed-ended questionnaire coupled with bottled and public water quality sampling and analysis at households reporting diarrhea cases. The water quality analysis showed contamination at the household level due primarily to the location of water storage tanks, as well as in some brands of bottled water due to lack of enforcement of source monitoring. Descriptive statistics and chi-square distribution tests revealed significant difference in diarrhea cases in both study areas which was correlated with the educational level of household head, financial status, type of water storage tank, and corresponding cleaning frequency as well as the adoption of measures to treat water or the use of bottled water.
本研究通过对两个城市贫民窟腹泻发生率的比较评估，确定了影响病例流行率的显著因素。主要数据通过结构化的封闭式问卷，以及对报告腹泻病例的家庭进行瓶装和公共水质采样和分析，从两个地区收集。水质分析表明，家庭层面的污染主要是由于水箱的位置，以及一些品牌的瓶装水由于缺乏水源监测而造成的。描述性统计和卡方分布检验显示，两个研究区域的腹泻病例存在显著差异，这与家庭负责人的教育水平、财务状况、水箱类型以及相应的清洁频率以及处理水或使用瓶装水的措施的采用有关。
