目的调查深圳市中小学生每天饮水量。方法采用多阶段随机抽样的方法,在深圳市三所学校共抽取816名7～19岁中小学生。采用连续7天24小时的饮水记录表,用定量用具测量每次饮水量,记录饮水情况。分析不同性别、不同年龄段学生的饮水量和饮水种类。结果调查对象每天饮水量为(1225±557)ml/d,男生为(1303±639)ml/d,高于女生(1134±478)ml/d(P<0.01)。初中生(1389±541)ml/d和高中生(1318±641)ml/d的每天饮水量之间差异无显著性,但都高于小学生(1097±525)ml/d(P<0.01)。调查对象日均白水饮用量为(818±541)ml/d,饮料饮用量为(407±294)ml/d。结论深圳市儿童少年的饮水主要以白水为主,但对于低年龄段的学生还应加强饮水知识的宣传和教育。
Objective To investigate the daily drinking amount of primary and secondary school students in Shenzhen. Methods A total of 816 primary and secondary school students aged 7-19 years were enrolled in three schools in Shenzhen City using a multi-stage random sampling method. Using 24-hour drinking water record for 7 consecutive days, measure the amount of drinking water with a measuring appliance and record the drinking water. Analysis of different gender, age groups of students drinking water and drinking water types. Results The average daily drinking volume of the surveyed subjects was (1225 ± 557) ml / d and that of the male students (1303 ± 639) ml / d, higher than that of the girls (1134 ± 478) ml / d (P <0.01). There was no significant difference in daily drinking amount between junior high school students (1389 ± 541) ml / d and high school students (1318 ± 641) ml / d, but higher than primary school students (1097 ± 525) ml / d . The daily average white water consumption of the surveyed subjects was (818 ± 541) ml / d, and the drink consumption was (407 ± 294) ml / d. Conclusion The main drinking water for children and adolescents in Shenzhen is mainly white water, but for the students of lower ages, the publicity and education on drinking water knowledge should be strengthened.
