A Clinical Trial of SystemCHANGE to Improve Exercise, Diet and Health in HIV-Infected Adults
A study testing SystemCHANGE in people with HIV and Cardiovascular Disease, run by Case Western Reserve University at 1 site in United States.
Trial summary
HIV was once a fatal diagnosis, but due to treatment advances it is no longer a death sentence. Today, HIV-infected adults face a new challenge to their health; they are developing cardiovascular disease (CVD) earlier and more frequently than those not HIV-infected. Read more about this study

About this study
HIV was once a fatal diagnosis, but due to treatment advances it is no longer a death sentence. Today, HIV-infected adults face a new challenge to their health; they are developing cardiovascular disease (CVD) earlier and more frequently than those not HIV-infected. Reasons for this include toxic effects of HIV medications and activation of the immune system. Preventing cardiovascular disease in HIV-infected adults will help them live healthier lives; however, there is a lack evidence to help us to achieve this goal. Exercise prevents cardiovascular disease, but it is often not addressed in HIV care, due, in part, to a lack of practical interventions targeting this population. This study will address this problem by testing an intervention to improve and maintain exercise in HIV-infected adults.
This study will examine the impact of an innovative and sustainable intervention, adapted to the unique medical and psychosocial needs of HIV-infected adults, called SystemCHANGE-HIV. It consists of six sessions to help redesign an individual's environment and routines to increase exercise.This is a randomized trial in which half of the subjects will participate in the intervention and half will participate in a control condition. Measures include assessments of exercise, fitness, and the markers of cardiovascular health before and after the intervention to see if, and how, they changed.
Read the detailed description
Emerging evidence suggests that HIV infection is associated with a 1.5-2-fold higher risk of cardiovascular disease. This may be due, in part, to an increase in cardiometabolic risk factors related to the toxic effects of HIV medications, immune activation, and chronic inflammation. Interventions to prevent cardiovascular disease, accounting for the unique medical and psychosocial needs of HIV-infected adults, are needed.
Exercise has been shown to improve cardiometabolic risk and decrease cardiovascular disease. It has further been shown to improve cardiometabolic risk factors in some groups of HIV-infected adults in brief and intensely supervised trials. However, how to sustain exercise in this population with practical and scalable interventions that can be implemented in the home setting (i.e., free-living exercise) is unknown. The purpose of this is to test a novel, evidence-based intervention, SystemCHANGE-HIV, which holds promise for improving exercise in HIV-infected adults.
SystemCHANGE-HIV is a new behavior-change program that is based on a systems re-design model, in which the individual's daily routines are composed of a set of habits (behaviors) that can be changed. The intervention engages participants in a series of self-designed experiments to test ways to change their behaviors. The program involves six weekly group sessions to teach behavior-changing and exercise-improvement strategies, followed by monthly telephone booster sessions to encourage maintenance of beneficial effects. SystemCHANGE has significantly improved exercise adherence and cardiovascular risk factors in HIV-uninfected adults. The specific aims of our study are to (1) evaluate the 3-month and 6-month effects of SystemCHANGE-HIV on the amount and intensity of free-living exercise, and (2) describe the impact of SystemCHANGE-HIV on fitness (VO2 max) and cardiometabolic health.
To accomplish these aims, this is a longitudinal, randomized controlled trial (n=105) comparing the effects SystemCHANGE-HIV to those of an attention-control condition. The outcomes will be assessed for efficacy using biological and behavioral evaluations including: actigraphy, fitness assessments, and clinical laboratory assessments.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Exercise as Measured by Waist-Worn Actigraph (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02553291, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jul 2017.
