Abstract：
Adequate hydration is essential for the maintenance of health and physiological functions in humans. However, many older adults do not maintain adequate hydration, which is under-recognized and poorly managed. Older adults are more vulnerable to dehydration, especially those living with multiple chronic diseases. Dehydration is associated with adverse health outcomes in older adults, and acts as an independent factor of the hospital length of stay, readmission, intensive care, in-hospital mortality, and poor prognosis. Dehydration is a prevalent health problem in older adults, accounting for substantial economic and social burden. This review attempts to provide current knowledge of hydration including patterns of body water turnover, the complex mechanisms behind water homeostasis, the effects of dehydration on the health of the body, and practical guidance for low-intake dehydration in older adults.
摘要：
充足的水合对于维持人类的健康和生理功能是必不可少的。然而,许多老年人不能保持足够的水分，这是认识不足和管理不善。老年人更容易脱水,尤其是那些患有多种慢性疾病的人。脱水与老年人的不良健康结果有关，并作为住院时间的独立因素，重新接纳,重症监护,住院死亡率，预后不良。脱水是老年人普遍存在的健康问题，考虑到巨大的经济和社会负担。这篇综述试图提供当前的水合知识，包括体内水分周转的模式，水稳态背后的复杂机制，脱水对身体健康的影响，和老年人低摄入脱水的实用指导。
