在尼泊尔，所有年龄段因腹泻住院的人数都非常高。根据世界卫生组织的说法，通过安全的饮用水源可以大大预防腹泻疾病。在加德满都谷地，由于自来水短缺，当地居民使用地下水、水罐和油罐水等替代水源。然而，这些替代水源可能受到污染。这项研究旨在阐明腹泻风险与饮用水源组合之间的关系。2015年至2016年期间进行了三次关于腹泻发生、水源和水处理的多重问卷调查。与不饮用相比，饮用罐装水（OR 6.1）和罐装水（OR 8.4）发生腹泻的比值比（OR）显著高。罐水和罐水混合饮用比只饮用自来水的OR高1 log。反之，饮用地下水的OR值较低，说明居民不饮用受污染的地下水。总之，腹泻的发生不仅与水污染程度有关，而且与行为因素有关，即人们在选择多种水源时的谨慎管理。
In Nepal, the number of diarrhoea hospitalizations in all ages is seriously high. According to the World Health Organization, diarrheal diseases can be substantially prevented through safe drinking water sources. In the Kathmandu Valley, because of the shortage of piped water, local residents use alternative water sources, such as groundwater, jars and tanker water. However, these alternative water sources can be contaminated. This study aimed to clarify the relationship between diarrhoea risk and the combinations of drinking water sources. A survey using multiple questionnaires on diarrhoea occurrence, water sources and water treatment was conducted three time between 2015 and 2016. The odds ratios (ORs) of developing diarrhoea were significantly high for drinking jar (OR 6.1) and tanker water (OR 8.4) compared with not drinking. The combined drinking of jar and tanker water obtained the 1 log higher OR compared with drinking only piped water. Conversely, drinking groundwater had a low OR, implying that the residents refrained from drinking polluted groundwater. In conclusion, diarrhoea occurrence was related not only to the level of water contamination, but also to a behavioural factor, i.e. people's careful management of the choice of multiple water sources.
