Impact of Physical Activity Routines and Dietary Intake on the Longitudinal Symptom Experience of People Living with HIV (PROSPER-HIV)
Years: 2018-2023
Background
People living with HIV (PLHIV) experience a disproportionately high symptom burden (e.g. fatigue, insomnia, pain) with few treatment options. Non-pharmacological treatment options are highly desirable for symptom management among PLHIV who already experience high pill burden from multiple comorbid diseases. Building on our previous work, the PROSPER-HIV study will examine the effect of physical activity and dietary intake as effective symptom management strategies in 850 PLHIV.
Specifically, we will:
- Identify and characterize longitudinal, objectively-measured, physical activity and dietary patterns among PLHIV;
- 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; and
- 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.
Research Design
We will conduct a four-year, prospective, observational study of 850 participants who will complete an enhanced PRO assessment to measure physical activity and diet once a year for three years. We will integrate these measures in an enhanced annual assessment of PRO plus objective measures of physical activity, diet intake and anthropomorphic factors at four CNICS sites: ÐÇ¿Õ´«Ã½, University of Alabama at Birmingham, University of Washington, and Fenway Health. This study was registered at ClinicalTrials.gov .
