The overall aim of this study is to compare feasibility of body weight, body fat, body composition and activity assessments in elderly subjects in long-term care (LTC), nursing home, or assisted living facilities. This will be accomplished through the use of questionnaires in addition to devices that evaluate movement, body composition, and body weight.~The proposed study will consist of an initial intake visit on Day 1, followed by an at-home (i.e. LTC facility, nursing home, and/or assisted living facility) phase where the participant will wear two watch like devices one on each wrist and answer two questions on paper each day. There will be a second visit on day 8 where the participant will complete additional questionnaires and assessments. The participant will continue wearing the wrist-worn devices for days 9-14, with a final visit on day 15 for final assessments and device collection. A window of +/- 3 days will be allocated for the scheduling of all visits to accommodate participant's schedules and commitments. Activities will take place in the care facility where the participant resides, or the Laboratory for Human Neurobiology for those that will commute. The study procedures will be identical for all participants for all Frailty groups.
Reduction in appetite and/or food intake among older individuals is referred to as anorexia of aging (AOA, also known as Geriatric Anorexia). AOA is linked with myriad comorbidities associated with aging, contributes significantly to adverse health consequences in old age, and has been used as a predictor of morbidity and mortality. The overall aim of this study is to compare feasibility of body weight, body fat, body composition and activity assessments in elderly subjects in long-term care (LTC), nursing home, or assisted living facilities. This will be accomplished through the use of questionnaires in addition to devices that evaluate movement, body composition, and body weight.
