本文确定了1998年孟加拉国达卡洪水期间和之后因腹泻而易受洪水影响的医院就诊人群。每周观察到的霍乱和非霍乱腹泻病例数与洪水和洪水后时期的预期正常数进行比较，使用泊松广义线性模型获得了前两年和随后两年的季节特定平均值。腹泻病例的预期数量是在单独的模型中针对每一类潜在的修正因素进行估计的：性别、年龄、社会经济地位以及个人卫生和环境卫生习惯。在洪水期间，霍乱和非霍乱腹泻病例分别比预期高出近6倍和2倍。在洪水后时期，教育水平较低、居住在非水泥屋顶的家庭、饮用管井水（而不是自来水）、使用远距离水源和不卫生厕所的人患非霍乱腹泻的风险明显较高。饮用管井水和使用不卫生厕所的人患霍乱的风险要高得多。这项研究证实，社会经济地位低下的群体和卫生条件差的群体最容易受到与洪水有关的腹泻的影响。
This paper identifies groups vulnerable to the effect of flooding on hospital visits due to diarrhoea during and after a flood event in 1998 in Dhaka, Bangladesh. The number of observed cases of cholera and non-cholera diarrhoea per week was compared to expected normal numbers during the flood and post-flood periods, obtained as the season-specific average over the two preceding and subsequent years using Poisson generalised linear models. The expected number of diarrhoea cases was estimated in separate models for each category of potential modifying factors: sex, age, socio-economic status and hygiene and sanitation practices. During the flood, the number of cholera and non-cholera diarrhoea cases was almost six and two times higher than expected, respectively. in the post-flood period, the risk of non-cholera diarrhoea was significantly higher for those with lower educational level, living in a household with a non-concrete roof, drinking tube-well water (vs. tap water), using a distant water source and unsanitary toilets. The risk for cholera was significantly higher for those drinking tube-well water and those using unsanitary toilets. This study confirms that low socio-economic groups and poor hygiene and sanitation groups were most vulnerable to flood-related diarrhoea.
