A pilot study on water consumption was carried out in the Québec City region in April and May 1996 with 125 people using a 24-h recall plus a 2-day diary. Consumption of drinking water via liquid and food was assessed as well as the type of water consumed (tap, bottle or filtered water) and place of consumption (home or away from home). Most of the people (56%) were drinking some bottled water or filtered tap water and 25% of water intake was away from home. Food consumption was found to be a non-significant source of drinking-water intake. The average water consumption was nearly similar in exclusively tap-water consumers and bottled- or filtered-water consumers (1.5 vs. 1.7 l/day, P = 0.29) but two-thirds of the consumption in this last group is natural water, while it is mixed water in the bottled/filtered-water group. No significant difference in amounts consumed were found according to age, but older people drank hot beverages and soup more often. The present pilot-study was weakened by a low participation rate (14%). Incentive might be necessary to improve participation rate and data collection methods must also be simplified. A 24-h recall plus a 1-day diary seem sufficient and data on consumption could be limited to liquids, soups and cereals.
1996年4月和5月，在魁北克市地区开展了一项关于水消费量的试点研究，125人参与，采用24小时回忆法加两天的日记记录法。评估了通过液体和食物摄入的饮用水量，以及所消费水的类型（自来水、瓶装水或过滤水）和消费地点（家中或家外）。大多数人（56%）饮用一些瓶装水或过滤后的自来水，25%的水摄入量来自家外。发现食物消费是饮用水摄入的一个不显著来源。单纯饮用自来水的消费者和饮用瓶装水或过滤水的消费者的平均用水量几乎相似（分别为1.5升/天和1.7升/天，P = 0.29），但后一组中三分之二的消费是天然水，而在瓶装/过滤水组中是混合水。根据年龄，所消费的水量没有显著差异，但老年人更常饮用热饮和汤。本试点研究因参与率低（14%）而受到影响。可能需要激励措施来提高参与率，并且数据收集方法也必须简化。24小时回忆法加一天的日记记录法似乎就足够了，消费数据可以仅限于液体、汤和谷类食品。
