The purposes of this study were to evaluate the correlation between sarcopenia and water intake and investigate lack of daily water intake in the presence of sarcopenia in an elderly population.
Data from 3656 participants (1582 men and 2074 women) were analyzed using the Korea National Health and Nutrition Examination Survey. Sarcopenia was defined in accordance with the criteria of the Asia Working Group for Sarcopenia. Water intake was assessed using the dietary water adequacy ratio and was calculated by dividing the daily water intake from fluid by the recommended daily amount of 1000 mL in men and 900 mL in women.
Water intake from food (g/d and cup/d) and dietary water adequacy ratio (mL) were significantly lower in the sarcopenia group (757.8 g, 890.1 g, and 0.74 mL in men; 511.9 g, 757.8 g, and 0.70 mL in women, respectively) than in the non-sarcopenia group (878.4 g, 1015.1 g, and 0.81 mL in men; 581.3 g, 790.5 g, 0.74 mL in women, respectively). In elderly men, the odds ratio of sarcopenia in the lowest quartile increased to 1.47 (range, 1.13-1.91) in Model 2 compared with that in the highest quartile. In elderly women, the odds ratio of sarcopenia in the lowest quartile increased to 1.50 (range, 1.08-2.08) in Model 2 compared with that in the highest quartile.
The prevalence of sarcopenia in the elderly population was related to inadequate dietary water intake after adjusting for covariates. Adequate water intake in the elderly should be recommended to prevent dehydration-related complications, including sarcopenia.
本研究旨在评估肌少症与水摄入量之间的相关性，并探讨老年人中肌少症与每日水摄入量不足之间的关系。
使用韩国国家健康和营养检查调查的数据对 3656 名参与者（男性 1582 名，女性 2074 名）进行了分析。肌少症按照亚洲肌少症工作组的标准进行定义。水摄入量通过饮食水充足率进行评估，通过将每日液体摄入量除以男性推荐的每日 1000ml 和女性推荐的每日 900ml 来计算。
男性肌少症组的食物来源水摄入量（g/d 和杯/d）和饮食水充足率（mL）均显著低于非肌少症组（757.8g、890.1g 和 0.74mL；511.9g、757.8g 和 0.70mL）。女性肌少症组的食物来源水摄入量（g/d 和杯/d）和饮食水充足率（mL）均显著低于非肌少症组（878.4g、1015.1g 和 0.81mL；581.3g、790.5g 和 0.74mL）。在老年男性中，与最高四分位组相比，最低四分位组肌少症的比值比在模型 2 中增加至 1.47（范围 1.13-1.91）。在老年女性中，与最高四分位组相比，最低四分位组肌少症的比值比在模型 2 中增加至 1.50（范围 1.08-2.08）。
在调整了协变量后，老年人肌少症的患病率与饮食水摄入不足有关。应建议老年人摄入足够的水，以预防包括肌少症在内的与脱水相关的并发症。
