摘要：Introduction: Data on hydration status in older adults are scarce and there are very few studies focusing on the impact of physical activity (PA) on drinking behavior. Objective: To assess the impact of physical activity and sedentarism on fluid intake in Spanish elderly. Methods: 433 non-institutionalized Spanish older adults (58% females), aged 55-88 years, volunteered for the PHYSMED study. PA data were obtained by means of the Minnesota and EXERNET questionnaires. Population was divided into four groups: ILS (inactive and low sedentary), IHS (inactive and high sedentary), ALS (active and low sedentary) and AHS (active and high sedentary). Serum from fasting blood samples was analysed for osmolarity. Results: The mean of total liquid intake was 1,751 ± 628 mL/d. Significant differences were observed for total liquid intake between ILS/ALS and IHS/ALS (p
