Aims of this study were: 1) describe the hydration status of a select group of community dwelling women, 2) compare the results of various invasive (venopuncture) and a non-invasive assessment (Bioelectrical impedance analysis (BIA)) methods, and 3) explore differences in subject characteristics of those categorized as hydrated versus dehydrated. A physiological framework of fluid and electrolyte balance guided the study. The sample consisted of members of a select order of Religious Sisters from the Midwest, representing those who lived independently at the Motherhouse as well as in the community and those who lived in the assisted living facility. Mean age of the 80 subjects was 75.9 (SD=10.6) and ranged from 50 to 101 years. As part of the annual data collection for an epidemiological longitudinal study a venipuncture (routine procedure for a venous blood sample) and BIA measurements (HYDRA ECF/ICF system) were completed. Other data collected were cognitive status (MMSE) and functional performance (Guralnik Battery). Percent of body water below 45%, based on the calculation of total (intercellular + extracellular) body water divided by body weight, was used to categorize subjects as dehydrated. Standard categories used to determine dehydration for serum levels were: osmolality: equal to or greater than 300 mmol/kg; sodium: equal to or greater than 148 mmol/L, and BUN/Creatinine ratio: equal to or greater than 25. Only 4 subjects (5%) were categorized as dehydrated based on the BUN/Creatinine ratio standard while no subjects were identified as dehydrated for the other invasive measures. Thirty four (42.5%) were dehydrated based on BIA measurement. A positive association between all invasive and non-invasive assessment methods was found. Those classified as dehydrated based on the BIA had a significantly lower functional score. Further study is necessary to identify factors contributing to hydration status of this group, determine differences of this sample with other community dwelling women, as well as determine clinical usefulness of the assessment measurements.
