上海市闵行区家庭人均饮水量分析

Per Capita Drinking Water Intake among Households in Minhang District of Shanghai

  • 摘要: 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=0.044;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。

     

    Abstract: Objective To estimate the per capita drinking water intake among households in Minhang District of Shanghai,and to provide reference for health risk assessment.

    Methods Totally 270 households were selected by stratified random sampling method for a questionnaire survey on the type and intake of drinking water.

    Results The median value of drinking water intake per capita was 1.24 L/d among the households selected.A significant difference in drinking water intake per capita was found among families in different locations (H=9.529,P=0.009),and the families in urban areas consumed more water than the families in rural areas (Z=2.971,P=0.003).A correlation was found between drinking water intake per capital and income per capita (r=0.231,P < 0.001).The median values of per capita intake of boiled municipal supply water,bottled or barreled water,purified water,beverage,and instant-purified vending water was 1,0.72,1.33,0.17 and 0.67 L/d,respectively,and all the above parameters showed significant differences between the urban and the rural households (H=24.539,P < 0.001;H=8.716,P=0.013;H=10.006,P=0.007;H=12.737,P=0.002) except beverage (H=1.788,P=0.409).Moreover,a correlation of income per capita was also found with the average intake of bottled/barreled water or beverage (r=0.37,P=0.044;r=0.207,P=0.017,respectively).

    Conclusion The per capita drinking water intake among households in Minhang District of Shanghai is close to the national recommendation level.Households in rural areas show lower per capita drinking water intake than those in urban areas.
