[目的]了解闵行区家庭人均饮水量,为评价居民的饮用水健康风险提供基础资料。[方法]采用分层随机抽样方法抽取闵行区的270户家庭进行问卷调查,询问家庭饮用水类型及饮用水消费量。[结果]闵行区家庭人均饮水量的中位数为1.24 L/d;不同类型的镇(街道)家庭人均饮水量存在差异(H=9.529,P=0.009),城镇型高于农村型(Z=2.971,P=0.003);且家庭人均饮水量与人均收入存在相关性(r=0.231,P<0.001)。饮用不同类型饮用水的家庭,煮沸的市政水、瓶(桶)装水、净化水、饮料及现制现售水的家庭人均饮水量的中位数分别为1、0.72、1.33、0.17和0.67 L/d;且煮沸的市政水、瓶(桶)装水、净化水及现制现售水饮水量占饮用水总饮水量的比例均存在城乡差异(分别为H=24.539,P<0.001;H=8.716,P=0.013;H=10.006,P=0.007;H=12.737,P=0.002);而饮料消费量占总饮水量的比例未见城乡差异(H=1.788,P=0.409)。此外,家庭人均瓶(桶)装水及饮料消费量均与人均收入存在相关性(分别为r=0.37,P=0.0 44;r=0.207,P=0.017)。[结论]闵行区家庭人均饮水量与我国饮用水推荐量相近,城乡家庭饮水量构成存在差异,农村家庭人均饮水量偏低。
[Objective] To understand the per capita drinking water consumption of households in Minhang District and provide basic information for assessing residents’ health risk of drinking water. [Method] A stratified random sampling method was used to sample 270 households in Minhang District to conduct questionnaire survey to inquire about the type of household drinking water and drinking water consumption. [Results] The median per capita drinking water consumption of households in Minhang District was 1.24 L / d. There was a significant difference in drinking water per capita among different types of towns (H = 9.529, P = 0.009) = 2.971, P = 0.003); and there was a correlation between per capita household water consumption and per capita income (r = 0.231, P <0.001). Median drinking water consumption per capita for households that drink different types of drinking water, boiled municipal water, bottled water (bottled water), purified water, beverages and current water distributions was 1,0.72, 1.33, 0.17 and 0.67 L / d. There was also a difference between urban and rural areas in the proportions of boiled municipal water, bottled water (bottled water), purified water and current water supply to total drinking water consumption (H = 24.539, P <0.001; H = 8.716, P = 0.013; H = 10.006, P = 0.007; H = 12.737, P = 0.002). There was no difference between urban and rural areas (H = 1.788, P = 0.409). In addition, per capita bottle (barrel) water consumption and beverage consumption per household correlated with per capita income (r = 0.37, P = 0.044; r = 0.207, P = 0.017, respectively). [Conclusions] The per capita drinking water consumption per household in Minhang District is similar to the recommended quantity of drinking water in our country. The composition of drinking water in urban and rural areas is different, and the per capita water consumption of rural households is low.
