Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Sedentary Behavior Cognitive Impairment Behavioral: Ecological Momentary Intervention Not Applicable

Detailed 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 39 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This is a pilot randomized, controlled trial of a 6-week intervention for feasibility. Outcome measures will be obtained at baseline and at 6-weeks. Behavior choices and preference data will be continuously captured during the intervention. We will randomize 80 older Latinos from the Chicago Latino community to either an ecological momentary intervention using fitbits (n=40) or to physical activity guidelines (n=40).

Arm Intervention/treatment
Experimental: Ecological Momentary Intervention
Participants will receive real time physical activity notifications via a wearable activity tracker and smartphone application.
Behavioral: Ecological Momentary Intervention
Participants will wear a Fitbit that has been programmed to deliver a notification (a buzz) when activity has ceased for more than 10 minutes. They will receive suggestions on their Illumivu mEMA smartphone app on how to replace sitting time with PA such as standing up 5 times or taking 20 steps, or even performing a short (20 seconds) preferred dance routine. Fitbit data will be captured in real-time via the iCardia platform. Participants will receive reminders from their smartphones to enter real-time feedback on activity options selected and how successful they were in adopting the option. These data will allow tracking of underlying preferences for behaviors and to tailor the program accordingly.
Other Name: Illumivu mEMA

No Intervention: Physical Activity Guidelines
Participants will be sent general guidelines for disruption of sedentary time.

Primary Outcome Measures :
  1. Sedentary Time [ Time Frame: Baseline to end of 6 weeks ]
    Change in sedentary time from baseline to 6 weeks follow up

Secondary Outcome Measures :
  1. Cognitive Function [ Time Frame: Baseline to end of 6 weeks ]
    Change in cognitive function measures assessed through the NIH Toolbox from baseline to 6 weeks

  2. Feasibility and Acceptability [ Time Frame: End of 6 weeks ]
    Formative assessments of usage of the smartphone app and participants' behavioral choices
