Details and patient eligibility

About

To test the feasibility of an intervention designed to replace sedentary time with physical activity in older Latinos, delivered in their homes to improve cognitive function and brain connectivity.

Full description

After being informed of the study and potential risks, all patients giving informed consent will undergo a focused phone interviews, followed by screening to determine eligibility. Participants that meet inclusion criteria will undergo baseline cognitive function testing via video (following NIH toolbox guidelines for remote cognitive function assessment), followed by a one week measurement of sedentary time using a physical activity monitor (actigraphy). At week 0, participants will be randomized into either a physical activity group to break up sedentary time or activity guidelines only in a 1:1 ratio. Follow up occurs at 6 weeks using the same measures as baseline.

Enrollment: 39 patients

Sex: All

Ages: 55 to 89 years old
