目的调查我国4个城市成年居民夏季每天饮水量.方法采用多阶段随机抽样方法,从北京、上海、成都、广州4个城市中抽取18～60岁城乡居民1483名.采用连续7 d的饮水记录法,了解调查对象的饮水情况,由调查对象利用定量用具估计每次饮水量,并记录每次饮水种类.分析不同城市、性别、城乡调查对象饮水种类和饮水量.结果调查对象每天饮水量的中位数为1488 ml,北京、上海、成都、广州分别为1579、1793、1150、1467 ml,各城市之间的差异有统计学意义(χ2=154.31,P=0.000);男性每天饮水量中位数(1679 ml)多于女性(1370 ml)(Z=8.34,P=0.000);城区调查对象每天的饮水量中位数(1514 ml)与农村(1466 ml)相比,差异无统计学意义(Z=-0.81,P=0.420).调查对象每天饮用白水、茶水、饮料的中位数分别为786、109和186 ml.在4个城市中,白水饮用量最高的是广州(917 ml);茶水饮用量最高的是上海(257 ml);而饮料饮用量在上海(323 ml)和北京(264 ml)较高.男性茶水的饮用量为229 ml,高于女性的57 ml(Z=7.52,P=0.000);城区调查对象每天白水的饮用量(693 ml)低于农村(914 ml).每天的饮水量不到1200 ml的调查对象占32.4%(480/1483).结论我国成年居民每天饮水量及白水、茶水、饮料饮用量存在城市、城乡、性别的差异;约1/3的居民每天饮水量未达到目前我国1200 ml的饮水建议量.

Objectives To investigate total drinking water intake of adults in the four cities of China in summer.Methods A total of 1483 adults aged 18-60 yrs from Beijing,Shanghai,Chengdu and Guangzhou were selected using multiple-stage random sampling method.The information of amounts and types of daily drinking water was recorded by subjects for seven consecutive days using a quantitative measurement.The amounts and types of daily drinking water among different cities and between men and women or urban and rural was analyzed.Results The median of daily total drinking water of subjects was 1488 ml,with significant difference among the four cities(1579,1793,1150,1467 ml in Beijing,Shanghai,Chengdu and Guangzhou city,respectively,χ2=154.31,P=0.000).The median of daily drinking water was significantly higher in men(1679 ml) than women(1370 ml)(Z=8.34,P=0.000),but no significant difference was found between urban(1514 ml) and rural (1466 ml)daily drinking water median (Z=-0.81,P=0.420).The median of daily consumption of plain water,tea and beverages were 786,109,186 ml,respectively.Among four cities,the highest consumption of plain water was in subjects of Guangzhou (917 ml),while the highest tea consumption in Shanghai (257 ml) and the highest beverages consumption in Shanghai (323 ml) and Beijing (264 ml).Consumption of tea in men(229 ml)was significantly higher than that in women (57 ml) (Z=7.52,P=0.000).Subjects in urban (693 ml) had lower consumption of plain water than those in rural (914 ml).The proportion was 32.4% (480/1483) for subjects with water drinking less than 1200 ml per day.Conclusion The daily consumption of total drinking water,including plain water,tea and beverages is different in adults among different cities and is different in gender and regions.It is nearly 1/3 of subjects with daily total drinking water less than current Chinese recommended water intake (1200 ml).
