The problem of dehydration among the elderly is well documented. Yet interventions to addresses this problem cannot be adequately tested until non-invasive approaches to measure hydration status among the elderly are established. The aims of this study are: Aim 1. Identify the validity of the non-invasive hydration measures (bio-impedance analysis (BIA), urine color and urine specific gravity) using serum osmolality as the gold standard. Aim 2. Explore subject characteristics that compromise the validity of the non-invasive hydration measures as a measure for hydration reflective of serum osmolality. Aims of this study are addressed using a methodological design, with validity of the physiological measure (BIA) established using the criteria of Gift and Soeken (1988). A physiologic framework of hydration and the aging process guided the development of this study. The study is in process. A total of 60 elderly subjects is planned with 30 subjects each from two settings, a nursing home and a medical psychiatric inpatient unit. Multi-frequency BIA measurements will be obtained from all subjects. Serum osmolality, urine specific gravity and urine color will be obtained from the electronic laboratory records for the hospitalized group. A blood draw and urine sample will be obtained from the nursing home group participants for determination of serum osmolality, urine specific gravity and urine color. The diagnostic validity of the findings from non-invasive hydration measures (BIA, urine SG and color) will be determined by associating the results of each with serum osmolality (gold standard). Subject characteristics will be obtained from medical records. Initial results of the study will be presented. Application of the results as bases for development of intervention studies will be discussed.
