Abstract

Background: Dehydration is the most common fluid and electrolyte problem among elderly people. The elderly leading an active lifestyle may be a risk group vulnerable to dehydration. Objective: The goals of the study were: to assess hydration status and the fluid intake, to determine gender differences in hydration status and fluid intake, and to determine the role of physical activity on hydration status in free-living elderly people. Methods: The research sample included 105 participants aged 67.2 ± 3.7 years (52% women) living independently in their own homes. Urine specific gravity (USG) was used to evaluate the hydration status (dehydration was defined as USG ≥ 1.020 and serious dehydration as USG > 1.030). A 4-day food record was used to monitor fluid intake, and the International Physical Activity Questionnaires - Short Form was used to assess physical activity. Results: The prevalence of dehydration was 45.7% with a lower prevalence in women. Serious dehydration was prevalent in two participants. Average daily beverage intake was 1144.4 ± 445.2 ml. There was no gender difference in total fluid intake. However, only 27.3% of women and 4.0% of men fulfilled the recommended daily fluid intake. Participants with moderate or high levels of physical activity had a better hydration status compared to their low-physical activity peers. Conclusions: These results indicate that almost half of elderly adults are dehydrated. The study suggests that being physically active can contribute to better fluid replenishment.

捷克老年人的水合状态:性别和体育活动差异
背景:脱水是老年人最常见的液体和电解质问题。生活方式积极的老年人可能是容易脱水的风险群体。目的:本研究的目的是:评估自由生活老年人的水合状态和液体摄入,确定水合状态和流体摄入的性别差异,并确定体育活动对水合状态的影响。方法:研究样本包括105名参与者,年龄67.2±3.7岁(52%为女性),在自己的家中独立生活。使用尿液比重(USG)来评估水合状态(脱水定义为USG≥1.020,严重脱水定义为USG>1.030)。使用4天的食物记录来监测液体摄入,并使用国际体力活动问卷-简表来评估体力活动。结果:脱水发生率为45.7%,女性脱水发生率较低。两名参与者普遍严重脱水。平均每日饮料摄入量为1144.4±445.2 ml。总液体摄入量没有性别差异。然而,只有27.3%的女性和4.0%的男性达到了建议的每日液体摄入量。与低体力活动的同龄人相比,中等或高体力活动的参与者具有更好的水合状态。结论:这些结果表明,几乎一半的老年人脱水。研究表明,积极锻炼身体有助于更好地补充体液。
