Geriatric Anorexia Study

Boston University51 enrolled

Overview

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 assess the feasibility and burden of the proposed in-laboratory and out-of-laboratory assessments to study Geriatric Anorexia. This will be accomplished with the use of questionnaires as well as devices that evaluate movement, metabolism, body weight composition, glucose levels, and nutritional scale.

This is a study to evaluate movement, metabolism, body weight composition, glucose levels, and nutritional scale in healthy adults. Subjects, age 65 to 85 years will be recruited. The proposed study will consist of an initial (in-clinic) intake visit on Day 1 where the subject will be screened and enrolled in the study after signing an informed consent document, followed by an at-home phase where the subject will wear a watch like device on one wrist. After training, the subject will return for their Day 8 in-clinic visit, where the subject will repeat some intake assessments and activities, as well as some additional standing and walking activities. The subject will then be asked to perform at-home activities and assessments with the use of a smart phone, digital food scale, smart body weight scale, and continuous glucose monitor, while continuing to wear the watch-like device and a movement measurement device around their waist (Days 8-21). A final in-clinic visit will take place on Day 21 for final assessments and device collection. A +/- 4 days will be allocated for the scheduling of all visits to accommodate subject's schedules and commitments. All in-laboratory activities will take place in the Laboratory for Human Neurobiology while in-home activities will be completed in the subject's home. The study procedures will be identical for all subjects for the three groups.

Outcomes

Primary Outcomes

Assess the feasibility, usability, and compliance of wearing a GENEActiv watch in a geriatric population both in-clinic and remotely at-home.

One GENEActiv watch will be used on one wrist and one around the waist at a sampling rate of 50 Hz to measure movement in the x, y, and z direction across the study period.

Time frame: 21 days +/- 4 days

Assess the feasibility, usability, and compliance of food consumption tracking in a geriatric population both in-clinic and remotely at-home.

A food scale will be used to track food consumed in grams (g) throughout the study. The total number of meals consumed per day and across study period.

Time frame: 21 days +/- 4 days

Assess the feasibility, usability, and compliance of body weight composition measurements in a geriatric population both in-clinic and remotely at-home.

A body weight composition scale will be used to completion of daily weight measurement and track body weight in kilograms (kg) throughout the study.

Time frame: 21 days +/- 4 days

Assess the correlation of a GENEActiv watch with frailty phenotype in elderly participants.

One GENEActiv watch will be used on one wrist and one around the waist at a sampling rate of 50 Hz to measure movement in the x, y, and z direction. This data will be compared to frailty phenotype per the Fried Frailty Scale and continuous glucose measurements.

Time frame: 21 days +/- 4 days

Assess the correlation of food consumption with frailty phenotype in elderly participants.

A food scale will be used to track food consumed in grams (g) throughout the study. This data will be compared to frailty phenotype per the Fried Frailty Scale.

Time frame: 21 days +/-4 days

Assess the correlation of the body weight composition scale with frailty phenotype in elderly participants.
