我国两城市成人饮水摄入量调查

Investigation on Drinking Water Intake of Adults in Two Cities of China

目的了解我国成人饮水摄入量的情况,为进行饮水暴露途径的健康风险评价提供基础参数依据。方法于2015年冬夏两季,在我国南北两个城市针对18岁及以上的成人居民进行饮水摄入量调查,采用问卷调查和自填式日志相结合的方法获得饮水摄入情况。结果调查对象以饮用开水为主,只喝开水或以饮用开水为主的占95.9%;自来水是主要饮水来源(70.1%)。日均饮水摄入量中位数为1 869.5 m L,以直接摄入为主。饮水摄入量夏季高于冬季,男性高于女性。随着BMI指数升高,日均饮水摄入量有升高的趋势,BMI指数≥28的人群最高。体力劳动者日均饮水摄入量高于非体力劳动者。结论成人日均饮水摄入量受多种因素影响,在健康风险评价时应综合考虑我国的实际情况。

Objective To acquire the drinking water intake parameters,providing basic data reference for the waterborne pollutants health risk assessment. Method In the summer and winter of 2015,randomly selected adults over the age of 18 residents were investigated for drinking water intake parameters,using questionnaires and self-administered logs method. Results In the investigated area,boiled tap water was mainly used as drinking water.The average daily water intake median was 1 869. 5 m L. Daily water intake was higher in summer than in winter,and also higher in male than in female. With the BMI index increased,daily intake of drinking water increased,which was highest in population with the BMI index of more than 28. The daily drinking water intake of manual workers was higher than that of non manual workers. Conclusion Adult daily drinking water intake is affected by many factors,and the actual situation of China should be taken into consideration in the health risk assessment.
