Impact of physical activity and sedentarism on hydration status and liquid intake in Spanish older adults. The PHYSMED study

Abstract

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 fl uid 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. Signifi cant differences were observed for total liquid intake between ILS/ALS and IHS/ALS (p < 0.001). ALS subjects consumed a higher amount of beverages such as water, juice, milk, coffee, sport drink, beer, wine and distilled drinks than the other PA groups. There was a signifi cant difference for water intake between PA groups (p < 0.01). Serum osmolarity values were within references ranges in all subjects, and there was a signifi cant difference between PA groups (p < 0.01). Conclusions: Spanish older adults meet the DACH recommendations set by the German, Austrian and Swiss nutrition societies' liquid intake recommendations in the mean independently of PA and sedentary level. All participants are within reference ranges of serum osmolarity. Subjects in the active and low sedentary group consumed higher amounts of water and other beverages than in the other PA groups.

Physical activity and sedentary behavior impacts on dietary water intake and hydration status in Spanish schoolchildren: A cross-sectional study

“…As far as we know, the effects of compliance with the PA guidelines on the state of hydration in schoolchildren have not been evaluated. Similar data have been found in the PHYSMED study [61] conducted in a Spanish adult population aged 55 to 88 years old in which, similar to the results obtained in the present study, significant differences were observed in the plasma osmolality between the "sedentary inactive" and "non-sedentary active" groups.…”

Hydration status in Czech elderly adults: Gender and physical activity differences

“…The study confirmed on the sample of 6508 participants aged > 18 years that the greater the physical activity, the greater the beverages consumption. Finally, the same pattern was found in a Spanish study involving 433 non-institutionalized older adults aged 55-88 years (Aparicio-Ugarriza et al, 2016). It is therefore probable that people with regular PA have an overall healthier lifestyle, including better fluid replenishment.…”

Is Energy Expenditure or Physical Activity Considered When Energy Intake Is Measured? A Scoping Review 1975–2015

“…Nutrient adequacy and food patterns have been linked to PA, with a higher percent of subjects meeting DRIs with increased PA level [ 39 ]. In a study performed in elderly Spanish subjects, higher amounts of water and other beverages were consumed by those being active and low sedentary than in the other PA groups [ 40 ]. Positive metabolic effects of regular PA are explicitly demonstrated in the scientific literature [ 41 ].…”
