Abstract

OBJECTIVE

To understand the status on knowledge of drinking water among adults aged 18 - 60 yrs in Beijing, Shanghai, Chengdu and Guangzhou of China.

METHODS

A total of 1483 adults aged 18 - 60 yrs from the four cities (Beijing, Shanghai, Chengdu and Guangzhou) were selected using multiple-stage random sampling method. The information was collected by face-to-face interview. Through face to face interview, investigators surveyed the daily water intake, the harm of dehydration, time of drinking water and healthy drinks knowledge using a questionnaire. Knowledge awareness was compared through χ(2) test for different cities, urban and rural, genders.

RESULTS

The unawareness rate of minimum drinking water volume (1200 ml/d) was 28.4% (421/1483). The rate in Chengdu was the highest (41.8%, 156/373). The rate in women (32.4%, 241/745) was significantly higher than that in men (24.4%, 180/738) (χ(2) = 11.55, P < 0.01). The unawareness rate of the harm of dehydration was 14.4% (213/1483). The rate in Chengdu (18.5%, 69/373) and Guangzhou (18.3%, 68/371) was higher than that in the other cities. The rate in rural (18.6%, 137/736) was significantly higher than that in urban (10.2%, 76/747) (χ(2) = 21.47, P < 0.01). The people who considered drinking water when they felt thirsty as healthy behavior accounted for 48.3% (716/1483). The rate in Chengdu was the highest (59.0%, 220/373). The unawareness rate of plain water being the best accounted for 18.9% (280/1483), while 17.9% (50/280) of them considered beverages as the best.

CONCLUSIONS

The knowledge of drinking water among 18 - 60 yrs residents in the four cities is not comprehensive. We should enhance propaganda of healthy drinking water.

摘要

目的

了解中国北京、上海、成都和广州18 - 60岁成年人的饮用水知识状况。

方法

采用多阶段随机抽样方法，从这四个城市（北京、上海、成都和广州）共选取1483名18 - 60岁的成年人。通过面对面访谈收集信息。调查人员通过面对面访谈，使用问卷对每日饮水量、脱水危害、饮水时间和健康饮品知识进行了调查。通过χ²检验比较不同城市、城乡、性别的知识知晓情况。

结果

最低饮水量（1200毫升/天）的知晓率为28.4%（421/1483）。成都的知晓率最高（41.8%，156/373）。女性的知晓率（32.4%，241/745）显著高于男性（24.4%，180/738）（χ² = 11.55，P < 0.01）。脱水危害的知晓率为14.4%（213/1483）。成都（18.5%，69/373）和广州（18.3%，68/371）的知晓率高于其他城市。农村地区的知晓率（18.6%，137/736）显著高于城市地区（10.2%，76/747）（χ² = 21.47，P < 0.01）。认为感到口渴时饮水是健康行为的人群占48.3%（716/1483）。成都的这一比例最高（59.0%，220/373）。认为白开水是最佳饮品的知晓率为18.9%（280/1483），其中17.9%（50/280）的人认为饮料是最佳饮品。
