Literature reporting total daily water intake of community-dwelling older adults is limited. We evaluated differences in total water intake, water sources, water from meal and snack beverages, timing of beverage consumption, and beverage selection for three older age groups (young-old, 65-74 years; middle-old, 75-84 years; and oldest-old, >or=85 years).
Data for 2,054 older adults from the 1999-2002 National Health and Nutrition Examination Survey were used for this study. Multivariate analyses controlling for age, sex, race-ethnicity, education, and marital status were conducted to determine differences in water intake variables across the age groups.
Total water intakes found for the middle-old and oldest-old age groups were significantly lower than those found for the young-old age group. The relative contributions of beverages to total water intake were 40.8%, 38.3%, and 36.4% for the young-old, middle-old, and oldest-old, respectively. The water intakes from beverages consumed at snack occasions were significantly lower for the middle-old and oldest-old groups than those for the young-old group. All groups consumed the greatest amount of water in the morning. Coffee was the predominant source of water from beverages for all groups.
This study fills a gap in the literature by providing an analysis of the daily water intake of middle-old and oldest-old adults. We found that the total water intake for the middle-old and oldest-old was significantly lower than that for the young-old. Future research needs to investigate the clinical outcomes associated with declining water intakes of community-dwelling older adults.
关于社区居住老年人每日总饮水量的文献报道有限。我们评估了三个老年年龄组（年轻老人，65 - 74岁；中年老人，75 - 84岁；高龄老人，≥85岁）在总饮水量、水源、餐食和零食饮料中的水分、饮料饮用时间以及饮料选择方面的差异。
本研究使用了1999 - 2002年全国健康与营养检查调查中2054名老年人的数据。进行了多变量分析，控制年龄、性别、种族 - 民族、教育程度和婚姻状况，以确定各年龄组在饮水量变量上的差异。
中年老人和高龄老人组的总饮水量显著低于年轻老人组。饮料对总饮水量的相对贡献在年轻老人、中年老人和高龄老人组中分别为40.8%、38.3%和36.4%。中年老人和高龄老人组在吃零食时饮用饮料的饮水量显著低于年轻老人组。所有组在上午饮水量最大。咖啡是所有组饮料中主要的水分来源。
本研究通过分析中年老人和高龄老人的每日饮水量填补了文献中的空白。我们发现中年老人和高龄老人的总饮水量显著低于年轻老人。未来的研究需要调查社区居住老年人饮水量下降相关的临床结果。
