    • Objectives To understand the drinking water intake of urban residents in Anning district, Lanzhou to provide basic data for assessing the health risk on drinking water intake.
      Methods A total of 491 adult residents were randomLy selected by multiple-stage stratified cluster from Anning district in Lanzhou in July, August and December of 2017. The information on drinking water intake of residents was investigated by using quantitative measurement and questionnaire survey. Wilcoxon rank sum test and Kruskal-Wallis rank sum test were used for stratified analysis of drinking water intake.
      Results The median of total drinking water intake, direct drinking water intake and indirect drinking water intake were 2 210, 1 750 and 390 mL/d among all residents in Lanzhou, respectively. The total drinking water intake and direct drinking water intake of male (2 339 and 1 800 mL/d) was higher than that of female (2 032 and 1 600 mL/d) (P < 0.05); The total drinking water intake, direct drinking water intake and indirect drinking water intake were the highest in 45~64 year-old people, which were 2 409, 1 800 and 424 mL/d, respectively. The amount of total water intake and direct water intake were statistically different in different age groups. The result also showed that the total drinking water intake and direct drinking water intake among people of different age and gender in summer and winter were different significantly.
      Conclusions Gender and age should be taken into account in the assessment of health risk of drinking water intake in Lanzhou.
