摘　　要：目的了解河北省某高校大学生春季日均饮水次数与每次饮水量及其之间的关系,为修订中国居民适宜饮水量提供基础数据。方法采用单纯随机抽样的方法抽取河北省某高校156名大学生,采用连续7 d 24 h饮水记录法,记录其每次的饮水量和饮水种类,分析不同性别、体质量指数大学生饮水次数及每次饮水量差异。结果大学生每天饮水量中位数为1 135 mL,饮水次数中位数为6次,每次饮水量中位数为177 mL。饮水次数<6次的人群比例为34.6%。女生每天饮水次数和饮用白水次数高于男生(χ~2/Z值分别为8.34,-2.03,P值均<0.05);男生每次饮水量、每次饮用白水和饮料的量高于女生(χ~2/Z值分别为23.86,-5.48,3.70,P值均<0.01);不同体质量指数大学生每次饮用白水的量差异有统计学意义(χ~2=9.17,P=0.03)。调查对象每次饮水量与体表面积呈正相关(r=0.18,P=0.03),饮水次数与饮水量呈正相关、与每次饮水量呈负相关,饮水量与每次饮水量呈正相关(r值分别为0.30,-0.47,0.61,P值均<0.01)。结论大学生存在一定比例的不良饮水行为;饮水行为在不同性别、体质量指数大学生间有差异;随着饮水次数的增加,每次饮水量减少,但是饮水量增加。Objective To investigate the association of within-day drinking occasions with average amount consumed per drinking occasion during spring among college students in Hebei Province and to provide the basic data for the revision of quantity of consumption among Chinese residents. Methods A total of 156 college students in Hebei Province were selected by using simple random sampling method. Information on daily amount and types of water consumption was recorded using the 7-day 24-hour recording method. The daily amount and type of drinking water by sex and BMI were analyzed and compared. Results The daily median drinking water intake was 1 135 mL;the daily median number of drinking occasion was 6, with 34.6% of participants less than 6 drinking occasions;the median amount consumed per drinking occasion was 177 mL. The daily number of water and plain water drinking occasion of females were higher than males(χ~2/Z=8.34,-2.03, P<0.05);the amount consumed per drinking occasion, the amount of plain water and beverages consumed per drinking occasion of males were higher than females(χ~2/Z=23.86,-5.48, 3.70, P<0.01);The differences of the amount of plain water consumed per day among students and their BMI were of statistical significance(χ~2=9.17, P=0.03), the amount of drinking water each time was positively correlated with body surface area(r=0.18, P=0.03), and frequency of drinking water was positively correlated with the amount of drinking water, negatively correlated with the amount of drinking water each time. The amount of drinking water was positively correlated with the amount of drinking water each time(r=0.30,-0.47, 0.61, P<0.01). Conclusion There is a certain proportion of unhealthy drinking behavior among college students;drinking behavior is different by sex and BMI. With the increase of drinking occasions, the amount consumed in each drinking occasion decreases, but total amount of drinking water increases.
