Impact of Physical Activity and Diet on Symptom Experience in People Living With HIV — PROSPER-HIV  

HIV/AIDS Clinical Trial

Official title: Impact of Physical Activity Routines and Dietary Intake on the Longitudinal Symptom Experience of People Living With HIV

Status Recruiting

Clinical Trial Summary

We will conduct a four-year, observational study of 850 participants to measure physical activity and diet, once a year for three years. All participants will also complete the standard Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) patient-reported outcomes (PRO) and clinical assessment procedures. An enhanced PRO assessment (consisting measures of physical activity, diet intake and anthropomorphic factors) will be included after the routine patient clinic visit at four CNICS sites: Case Western Reserve University, University of Alabama at Birmingham, University of Washington, and Fenway Health.

Clinical Trial Description

PROSPER-HIV is a four-year, prospective, observational study of 850 CNICS participants who will complete an enhanced patient-reported outcome (PRO) assessment to measure physical activity and diet intake, once a year for three years. All participants will also complete the standard CNICS PRO and clinical assessment procedures. We propose to integrate the following measures, physical activity (triaxial accelerometery), dietary intake (24-hour diet recalls), and anthropomorphic factors (waist-hip-ratio), into an enhanced annual assessment of patient reported outcomes at four CNICS sites: Case Western Reserve University, University of Alabama at Birmingham, University of Washington, and Fenway Health. Our four primary objectives are to:

1. Identify and characterize longitudinal, objectively measured, physical activity and dietary patterns among PLHIV

2. Examine the relationship between objectively-measured physical activity and self-reported physical activity on the Lipid Research Clinics Physical Activity Questionnaire.

3. Determine which aspects of physical activity patterns and diet quality are associated with decreased symptom burden and intensity in PLHIV, and if this relationship is moderated by age and sex.

4. Explore the potential mediating effect of anthropomorphic and physical fitness variables on the relationships between physical activity, dietary patterns, and symptom burden and intensity in PLHIV.

We hypothesize that people living with HIV who 1) have more intense, frequent and longer physical activity bouts will have age- and sex-dependent reduced symptom burden; 2) eat better quality diets (e.g., more fiber and protein, fewer carbohydrates) will have reduced symptom burden and intensity and that this relationship will also vary by age and sex. ;
