Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will aim to determine normal daily variation of the individual hydration level in longitudinal study on elderly in assisted living facility and assess a range of variation of individual hydration baselines for elderly in a normal physiologically hydrated state.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The subject pool will be comprised of 100 elderly (over 65 years old), male and female subjects who are residing in assisted living center. All subjects will provide written informed consent before participation. For the day prior testing and all testing days subjects will be encouraged to follow standard hydration guidelines for older adults by consuming 1200-2400 ml/day depending upon the body weight of subjects. The application of the HM will follow specific protocol based on the prototype HM user manual for specific anatomic locations. Triplicate measurements will be made for each time-point. All subjects will also be measured for bioelectrical impedance analysis (BIA) and estimation of total body water using a leg-to-leg BIA machine. To examine within-day and between-day variability and reliability of the HM a subgroup (N=25) of the 100 initial subjects will be selected. Within-day reliability will be evaluated by taking multiple measurements (3) during the day. Between-day reliability will include measurements (same time) for three consecutive days for the subgroup of 25 subjects. BIA measures will also be included during each of the time points for both within-day and between-day.
