摘　　要：目的了解兰州市城区居民夏季饮水量,为兰州市城区居民饮用水健康风险评价提供基础数据。方法于2017年7—8月采用整群随机抽样的方法 ,从兰州市所辖的四个城区中随机选取18岁及以上居民,通过问卷调查和标准量具相结合的方法进行入户调查居民经口饮水暴露参数。饮水量分层分析采用Wilcoxon秩和检验和Kruskal-Wallis秩和检验。结果兰州市城区居民夏季的总饮水量、直接饮水量、间接饮水量中位数分别为2 142.4、1 650.0和395.2 m L/d。男性总饮水量、直接饮水量、间接饮水量(2 289.2、1 800.0和、403.6 m L/d)均高于女性(2 031.7、1 500.0和379.9 m L/d)(P<0.05);(18~44)岁、(45~64)岁、65岁及以上人群的总饮水量中位数(2 113.6、2 365.6和1 823.8 m L/d)和直接饮水量中位数(1 650.0、1 800.0和1 325.0 m L/d)的年龄别差异均有统计学意义(P<0.05);体力劳动者间接饮水量中位数(429.6 m L/d)显著高于脑力劳动者(368.6 ml/d)(P<0.05);体质指数(BMI)<18.5、18.5~23.9、24.0~27.9、≥28.0~者的间接饮水量依次为318.8、397.4、426.9和421.6 m L/d,不同BMI者间接饮水量比较差异有统计学意义(P<0.05)。结论性别、年龄、劳动情况和BMI均对兰州市城区居民夏季饮水量有一定影响,在兰州市城区饮水健康风险评价中应综合考虑多因素条件下的饮水量。Objectives To acquire the drinking water consumption of urban residents in Lanzhou for health risk assessment.Methods Residents of 18 years old or older were selected randomly by a multiple-stage stratified cluster random sampling method from four areas in Lanzhou and assessed from July 2017 to August.2017.The information on drinking water exposure parameters of residents were investigated by using quantified measures combined with questionnaire survey.Wilcoxon rank sum test and Kruskal-Wallis rank sum test were used for stratified analysis of drinking water consumption.ResultsThe median value of total drinking water consumption,direct drinking water consumption and indirect drinking water consumption in Lanzhou urban residents in summer were2 142.4,1 650 and 395.2 m L/d,respectively.The total drinking water consumption,direct drinking water consumption and indirect drinking water consumption in male（2 289.2,1 800 and 403.6 m L/d）was higher than that in female（2 031.7,1 500 and 379.9 m L/d）（P〈0.05）.The total drinking water consumption of residents in the age of（18~44）,（45~64）and 65~year-old was 2 113.6,2 365.6 and 1 823.8 m L/d,respectively;and their direct drinking water consumption was 1 650,1 800 and 1 325 m L/d,respectively.The difference between different aged people was different statistically（P〈0.05）.The indirect drinking water consumption of manual workers（429.6 m L/d）was higher than that of non-manual workers（368.6 m L/d）（P〈0.05）.The indirect drinking water consumption of residents with a body mass index（BMI）of18.5,（18.5~23.9）,（24.0~27.9）and28.0~kg/m^2was 318.8,397.4,426.9 and 421.6 m L/d,respectively（P〈0.05）.ConclusionsGender,age,laboring situation and BMI might have an influence on drinking water consumption of residents in summer in Lanzhou,and these factors should be taken into account in health risk assessment.
