In order to investigate the factors affecting domestic water use in rural areas of developing countries, an analysis was performed of water consumption estimates from 1029 different households in Nicaragua collected between May 1986 and December 1988. Eight of the 22 variables hypothesized to be related to per capita domestic water consumption, were included in the final multiple regression model. These were; household size, site of clothes washing, the type of water source, mother's and father's levels of schooling, distance to the water source, wealth, and ownership of cattle. According to this model, a decrease in the distance to the water source from 1000 to 10 m is associated with an increase in per capita water consumption of 20%. Similarly, families where the mother has 6 years of schooling use 17% more water than families where the mother has had no formal education. The same difference in the father's schooling is associated with 12% greater per capita water consumption. A better understanding of the factors affecting domestic water use is needed to improve the design of interventions aimed at reducing the transmission of water-washed disease in developing countries.
为了调查影响发展中国家农村地区家庭用水的因素，对1986年5月至1988年12月期间在尼加拉瓜收集的1029个不同家庭的用水量估计进行了分析。假设与人均家庭用水量相关的22个变量中的8个被纳入最终的多元回归模型。这些变量是：家庭规模、洗衣地点、水源类型、母亲和父亲的受教育程度、到水源的距离、财富以及牛的拥有情况。根据该模型，到水源的距离从1000米减少到10米，人均用水量增加20%。同样，母亲接受过6年教育的家庭比母亲未接受过正规教育的家庭用水量多17%。父亲受教育程度的相同差异与人均用水量多12%相关。为了改进旨在减少发展中国家水传播疾病传播的干预措施的设计，需要更好地了解影响家庭用水的因素。
