The association of hydration knowledge and health habits with hydration status and fluid intake is rarely examined. We sought to determine whether knowledge or physical health behaviors predict physiological hydration status and fluid intake. Ninety-six participants (59 female; 27 ± 10 year) completed the previously validated hydration survey. Participants then recorded total fluids consumed (TFC), collected urine, and tracked void frequency for 24 h. Hydration status was assessed via 24 h urine specific gravity (USG) and osmolality (U). Health behaviors included self-reported physical activity, BMI, smoking, alcoholic drinking, and sleep status. TFC was significantly correlated with 24 h USG (r = -0.390; < 0.001), U (r = -0.486; < 0.001), total urine volume (r = 0.675; < 0.001), and void frequency (r = 0.518; < 0.001). Hydration knowledge was not correlated with 24 h USG (r = 0.085; = 0.420), U (r = 0.087; = 0.419), urine total volume (r = 0.019; = 0.857), void frequency (r = 0.030; = 0.771), or TFC (r = 0.027; = 0.813). Hydration knowledge did not predict 24 h USG (LR = 1.10; LR = 0.90), U (LR = 0.81; LR = 1.35), or TFC (LR = 1.00; LR = 1.00). Health habits did not predict 24 h USG, U, or TFC. In conclusion, self-reported 24 h diet and fluid log recording is comparable to hydration status verification via 24 h urine collection. Hydration knowledge and health habits are not related to, or predictive of, hydration status.
水合知识和健康习惯与水合状态和液体摄入的关系很少被研究。我们试图确定知识或身体健康行为是否可以预测生理水合状态和液体摄入。96 名参与者（59 名女性；27 ± 10 岁）完成了先前验证的水合调查。然后，参与者记录了总液体摄入量（TFC），收集了尿液，并记录了 24 小时的排尿频率。通过 24 小时尿液比重（USG）和渗透压（U）评估水合状态。健康行为包括自我报告的身体活动、BMI、吸烟、饮酒和睡眠状况。TFC 与 24 小时 USG（r = -0.390；<0.001）、U（r = -0.486；<0.001）、总尿量（r = 0.675；<0.001）和排尿频率（r = 0.518；<0.001）显著相关。水合知识与 24 小时 USG（r = 0.085；= 0.420）、U（r = 0.087；= 0.419）、总尿量（r = 0.019；= 0.857）、排尿频率（r = 0.030；= 0.771）或 TFC（r = 0.027；= 0.813）均无相关性。水合知识不能预测 24 小时 USG（LR = 1.10；LR = 0.90）、U（LR = 0.81；LR = 1.35）或 TFC（LR = 1.00；LR = 1.00）。健康习惯也不能预测 24 小时 USG、U 或 TFC。总之，自我报告的 24 小时饮食和液体日志记录与 24 小时尿液收集验证的水合状态相当。水合知识和健康习惯与水合状态无关，也不能预测水合状态。
