ObjectivesThe 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.MethodsData 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.ResultsWater 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.ConclusionsThe 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.Copyright © 2018 Elsevier Inc. All rights reserved.
