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...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。展开更多
