PURPOSE: This study compared the voluntary fluid intake behavior of older men and women (54-70 yr) when provided cold, palatable beverages and ample opportunity to drink between repeated bouts of exercise in the heat. METHODS: Thirteen men and 14 women performed four bouts of 15-min cycling at 65% VO2peak followed by 15 min of rest [...]

Water intake was described and quantified in samples of urban Guatemalan schoolchildren stratified by gender and socio-economic status. The frequency of consumption and quantity of plain water drinking was estimated from oneday pictorial registries of all beverages, foods and snacks consumed over a 24-h period collected from 449 3rd and 4th graders from two social [...]

Detecting and treating dehydration in hospitalized patients is critical because of the adverse outcomes associated with this condition. Using a case-control design, this study estimated the incidence, risk factors, and outcomes of dehydration in hospitalized adults. The overall incidence rate for developing one of three ICD-9 codes for dehydration during a hospital stay was 3.5%. [...]

After an early report that patients treated with angiotensin-converting enzyme (ACE) inhibitors had a lower than expected incidence of cancers, there was a large number of publications investigating the possible pathophysiological mechanism mediating this effect, as well as population studies comparing the incidence of cancers in patients treated with agents inhibiting the renin-angiotensin system with [...]

PURPOSE OF REVIEW: The intake of water and electrolytes is inseparable from the ingestion of nutrients by normal or artificial means. Recent reports have agreed in criticizing the poor standards of practice and of training in the management of fluid and electrolyte balance, resulting in a large amount of avoidable morbidity, particularly in the elderly [...]

AIM: This paper describes the findings of a descriptive study about what nurses do to ensure that older people with dementia have adequate hydration. BACKGROUND: Frail nursing home residents, particularly those who cannot accurately communicate their thirst as a result of Alzheimer's disease and who depend on nursing staff for their fluid intake, are at [...]

BACKGROUND: The study investigators conducted a vigorous screening protocol for delirium in rural long-term care (LTC) facilities for a period of 28 days focusing on Bioelectrical Impedance Analysis (BIA) and other hydration parameters as risk factors. METHODS: A two-stage cluster sampling procedure was used to randomly select participants (n = 313) from 13 LTC facilities [...]

To determine whether responses to dehydration are altered with age, we investigated the thirst, fluid and electrolyte responses, and hormonal responses to 24 hours of water deprivation in seven healthy active elderly men (67 to 75 years old) and seven healthy young men (20 to 31 years old) who were matched for weight loss during [...]

To assess the fluid regulatory responses in aging adults, we measured thirst perception and osmoregulation during and after infusion of hypertonic NaCl) saline in older (72 +/- 2 yr, n = 6) and younger (26 +/- n = 6) subjects. Hypertonic saline was infused at 0.1 min-1.kg-1 for 120 min. On a separate day, the [...]
