title: [Knowledge on drinking water of adults in four cities of China].
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.
