目的调查上海市中小学生日均饮水次数、饮水量及其关系,为制定儿童青少年的水推荐量提供参考。方法采用多阶段随机抽样的方法,于2011年9—10月在上海市共调查中小学生1 459名。采用连续7 d 24 h饮水记录法,详细记录每天每次饮水的种类及量,分析日均饮水次数与饮水量的关系。结果上海市中小学生每天的饮水量为(1 116.9±543.7)mL。日均饮水次数为(4.7±1.7)次,其中白水(3.0±1.5)次,饮料(1.5±0.9)次。每次饮水量为(251.8±104.7)mL,其中白水(244.8±126.2)mL,饮料(247.8±101.8)mL。日均饮水次数与每天饮水量呈正相关(r=0.587,P<0.05),与每次饮水量呈负相关(r=-0.188,P<0.05);每天饮水量与每次饮水量呈正相关(r=0.592,P<0.05)。结论上海市中小学生每日饮水总量、日均饮水次数较少;随着日均饮水次数增加,每次饮水量呈下降趋势,但每天饮水总量呈上升趋势。
Objective To investigate the average number of drinking water and water consumption of primary and middle school students in Shanghai and their relationship, and to provide reference for formulating water recommendation for children and adolescents. Methods A total of 1 459 primary and secondary school students were investigated in Shanghai from September to October in 2011 by adopting a multi-stage random sampling method. Using continuous 7 d 24 h drinking record method, a detailed record of the type and amount of drinking water every day, analysis of the relationship between the number of daily drinking water and drinking water. Results The daily drinking amount of primary and secondary school students in Shanghai was (116.16 ± 543.7) mL. The daily average number of drinking water was (4.7 ± 1.7) times, with white water (3.0 ± 1.5) times and beverage (1.5 ± 0.9) times. Each time drinking water was (251.8 ± 104.7) mL, including white water (244.8 ± 126.2) mL, beverage (247.8 ± 101.8) mL. The average daily drinking water intake was positively correlated with the daily drinking water volume (r = 0.587, P <0.05), and was negatively correlated with each drinking water volume (r = -0.188, P <0.05) r = 0.592, P <0.05). Conclusions The total daily drinking water intake and daily drinking water intake of primary and secondary school students in Shanghai are less. With the increase of daily drinking water quantity, the drinking water volume shows a downward trend, but the total daily drinking water volume shows an upward trend.
