‌A Clinical Trial of SystemCHANGE to Improve Exercise, Diet and Health in HIV-Infected Adults

Years: 2015-2018

Background

People living with HIV are at high risk for developing cardiovascular disease (CVD). Improving physical activity is an evidence-based strategy which when performed in a regular and sustained fashion, can help prevent and mitigate the severity of CVD. Yet, to achieve these benefits one must, over the long term, be physically active and regularly eat a health diet. An innovative approach to improving and maintaining health living behaviors such as physical activity and eating a healthy diet is the SystemCHANGE-HIV intervention. The BOBCAT Study aimed to:

  • Evaluate the short-term and maintenance effects of SystemCHANGE-HIV on the amount and intensity of exercise
  • To describe the impact of SystemCHANGE-HIV on cardiorespiratory fitness and cardiometabolic health

Research Design

A two-group, randomized, repeated measures design was used to test the 3 and 6 month effects of SystemCHANGE-HIV. Participants were randomized to receive one of two conditions: (1) SystemCHANGE-HIV intervention, or (2) enhanced usual care. Subjects completed measures at baseline, 3, 6 (primary endpoints), 12, and 24 months. This study was registered at ClinicalTrials.gov #NCT02553291

Results

This study is closed to new enrollment. All primary endpoints have been collected and are being analyzed.
