Physical activity and exercise for older people living with HIV: a protocol for a scoping review

BACKGROUND: Older people living with HIV (OPLWH) are expected to live longer in the era of antiretroviral treatment, but at the same time, they are at risk for developing various health complications as a consequence of a life with the infection, exposure to medications that carry their own toxicity and side effects, and the natural effects of aging on the immune system. Because senescence is an inherent process that can be accelerated by HIV, it is important to identify strategies that can modify this phenomenon. Emerging data suggests that while physical activity and exercise may not have a positive impact on viral replication and on the immune system of people living with HIV, it can elicit improvements in cardiorespiratory fitness, strength, body composition, and overall quality of life. The purpose of this study is to map out empirical evidence on the effects of physical activity and exercise in OPLWH. METHODS: The scoping review methods will be guided by the framework proposed by the Joanna Briggs Institute guidelines. Literature searches will be conducted in the following electronic databases (from inception onwards): PubMed/MEDLINE, Cochrane Library, and Google Scholar. Peer-reviewed journal papers will be included if they are written in English, involved human participants aged 50 years, and older with HIV and described a measure for physical, mental, or functional status of physical activity/exercise and/or the recommendations in OPLWH. Quantitative, qualitative, and mixed-method studies will be included in order to consider different aspects of measuring the effects of physical activity and exercise (e.g., quality of life, functional status, activities of daily living). Two reviewers will screen all citations and full-text articles. We will abstract data, organize them into themes and sub-themes, summarize them, and report the results using a narrative synthesis. The study methodological quality (or bias) will be appraised using a Mixed Methods Appraisal Tool. DISCUSSION: The evidence gathered from the selected studies will be discussed in relation to the research questions using a narrative to identify and explore emergent themes. The review will provide a baseline of evidence on exercise and physical activity interventions for OPLWH. It will highlight gaps regarding the use of exercise and physical activity and contribute to the design of an effective intervention approach to the rehabilitation of OPLWH.
