This study aims to find out how WASH practices may be responsible for the development of diarrheal disease and poor physical growth of under-five children in rural Noakahli, Bangladesh. A case study was conducted among 110 households who had children aged between 0 and 59 months chosen by simple random method at Noakhali district, Bangladesh. Bivariate and multivariate logistic regression was employed to find the association. About 40.1% of children had diarrhea within 1 week prior to the study and 38.9% had skin problems of different kinds. A significant association between wasting and hand washing before feeding the baby (p < 0.006) was found; stunting and family income also showed association (p < 0.003). Bathing the baby regularly, cleaning toilets, and cleanliness of the baby was found to be strongly associated; not cleaning toilets was associated with a very high risk of getting diarrhea (AOR: 16.397 (1.075–250.013)). Moreover, the unavailability of soaps in toilets increased the risk of diarrheal diseases (COR: 3.933 (1.258–12.296)) in the study population. Malnutrition is highly prevalent in children living in the study area and needs to be addressed by considering the factors which affect this rate.

这项研究旨在找出WASH做法如何导致腹泻病的发展以及孟加拉国Noakahli农村五岁以下儿童身体发育不良的原因。在孟加拉国的Noakhali区，对110个家庭进行了个案研究，这些家庭的孩子年龄在0至59个月之间，采用简单的随机方法选出。使用双变量和多元逻辑回归来找到关联。在研究之前的1周内，约有40.1％的儿童出现腹泻，而38.9％的儿童出现了各种皮肤问题。发现在喂养婴儿之前，浪费与洗手之间存在显着关联（p <0.006）。发育迟缓和家庭收入也显示协会（p<0.003）。定期给婴儿洗澡，清洁厕所和清洁与婴儿息息相关。不清洁厕所会导致腹泻的风险很高（AOR：16.397（1.075–250.013））。此外，在研究人群中，没有肥皂会增加腹泻疾病的风险（COR：3.933（1.258-12.296））。营养不良在居住在研究区域的儿童中非常普遍，需要通过考虑影响这一比率的因素来解决。
