mHealth Physical Activity Trial for Older HIV-infected Adults (mFIT)

Not Applicable
Completed
Conditions
HIV

Other: Digital Activity Tracker
Other: Smart Text Messaging
Registration Number
NCT03708640
Lead Sponsor
Johns Hopkins University
Brief Summary

This pilot study will examine the effect of a mobile health text messaging platform linked to a digital physical activity tracker on physical activity among persons living with HIV and frailty.

Detailed Description

HIV is associated with frailty, an important aging-related phenotype associated with adverse clinical outcomes. The investigators propose that personalized health coaching using a digital activity tracker with mobile health text messaging can increase physical activity in this population. The total duration of the intervention will be 12 weeks.

Primary Outcome Measures
NameTimeMethod
Change in Mean daily step countBaseline, 12 weeks

Mean daily step count will be assessed using a digital physical activity tracker

Secondary Outcome Measures
NameTimeMethod
Change in Frailty as assessed by the Fried-based physical frailty phenotypeBaseline, 12 weeks

Frailty evaluated based on the standard 5 point Fried-based frailty phenotype construct (slow gait, weakness, weight loss, exhaustion, low physical activity)

Percent change in lean massBaseline, 12 weeks

Lean mass will be measured using the dual-energy x-ray absorptiometry (DXA) scan

Change in Muscle strength as assessed by isokinetic resistanceBaseline, 12 weeks

Muscle strength evaluated using isokinetic resistance testing on a Biodex system measuring peak torque expressed as foot pounds (lbs)

Percent change in fat massBaseline, 12 weeks

Fat mass will be measured using the dual-energy x-ray absorptiometry (DXA) scan

Change in soluble Tumor Necrosis Factor Receptor 1 (sTNFR1)Baseline, 12 weeks

sTNFR1 concentration in ng/ml will be measured at baseline and be compared to the concentration at 12 weeks to assess any change

Change in Physical Fitness as assessed by 12 minute walkBaseline, 12 weeks

Physical fitness of participants will be assessed by the ability to do a 12 minute walk

Change in Interleukin-6 (IL-6) concentrationBaseline, 12 weeks

Interleukin-6 concentration in pg/ml will be measured at baseline and be compared to the concentration at 12 weeks to assess any change

Change in Physical performance as assessed by the physical performance batteryBaseline, 12 weeks

Physical performance evaluated with the short physical performance battery

Change in Quality of Life as assessed by the Medical Outcomes Study HIV Health Survey (MOS-HIV)Baseline, 12 weeks

The Medical Outcomes Study HIV Health Survey (MOS-HIV) is a brief, comprehensive measure of health-related quality of life. The 35-item questionnaire includes 10 dimensions (pain, physical, role, health perceptions, social and cognitive functioning, energy, mental health, health distress and quality of life). Each dimension is scored on a 0-100 scale (a higher score indicates better health related quality of life). An overall score is obtained through a summation of z scores from each domain.
