    Dropout from physical activity interventions in people living with HIV: a systematic review and meta-analysis
    (Taylor and Francis online : AIDS Care Psychological and Socio-medical Aspects of AIDS/HIV, 2017) Vancampfort, D.; Mugisha, J.; Richards, J.; De Hert, M.; Lazzarotto, A. R.; Schuch, F. B.; Probst, M.; Stubbs, B.
    Physical activity (PA) interventions have been shown to improve the health of people living with HIV (PLWH), yet treatment dropout poses an important challenge. We conducted a meta-analysis to investigate the prevalence and predictors of treatment dropout in PA interventions in PLWH. Electronic databases were searched for records up to September 2016. Randomized control trials of PA interventions in PLWH reporting dropout rates were included. Random effects meta-analysis and meta-regression analyses were employed. In 36 studies involving 49 PA intervention arms, 1128 PLWH were included (mean age = 41.6 years; 79.3% male; 39% White). The trim and fill adjusted treatment dropout rate was 29.3% (95% CI = 24.5–34.7%). There was a significant lower dropout rate in resistance training interventions compared with aerobic (p = 0.003) PA interventions, in studies utilizing supervised interventions throughout the study period (p < 0.001), and in studies using adequately qualified professionals (p < 0.001). Exerciser/participant variables that moderated higher dropout rates were a lower percentage of male participants (β = 1.15, standard error (SE) = 0.49, z = 2.0, p = 0.048), a lower body mass index(BMI) (β = 0.14, SE = 0.06, z = 2.16, p = 0.03), and a lower cardiorespiratory fitness (β = 0.10, SE = 0.04, z = 2.7, p = 0.006). The dropout from PA interventions is much higher in PLWH than in many other populations with chronic morbidities. Qualified professionals (i.e., exercise physiologists, physical educators, or physical therapists) should be incorporated as key care providers in the multidisciplinary care of HIV/AIDS and should prescribe supervised PA for PLWH in order to enhance adherence and reduce the burden of HIV/AIDS. Special attention should be given men, those with a higher BMI, and those with a lower cardiorespiratory fitness.

    Physical activity and HIV in Sub-Saharan Africa: a systematic review of correlates and levels
    (AJOL: African Health Sciences., 2018) Vancampfort, Davy; Stubbs, Brendon; Mugisha, James
    Self-management strategies such as physical activity (PA) can address disability and optimize mental, physical, social and economic outcomes for persons living with HIV (PLWH). Understanding factors that influence PA behavior in PLWH is a first step in order to devise effective interventions. Objective: The present review provides a systematic review of the correlates of PA in PLWH in sub-Saharan Africa. Methods: Electronic databases were searched till April 2016. Keywords included ‘physical activity’ or ‘exercise’ or ‘sports’ and ‘AIDS’ or ‘HIV’. Results: Ten correlates were identified in 6 studies including 1,015 (329♂) PLWH (mean age range=30.5-40.8years). Lower levels of PA were associated with older age (2/2 studies), a lower number of CD4 cells/μl (1/1), a more severe HIV-stage (1/1), a higher HIV load (1/1), the presence of opportunistic infections (1/1) and a higher BMI (1/1). Fisher’s exact tests showed there were more significant correlates in objective tools versus subjective self-report (P=0.03). Conclusion: The current review shows that participation in PA by PLWH in sub-Saharan Africa is associated with a range of complex factors which should be considered in the daily care of PLWH. This however might require repackaging of the current interventions for PLWH to allow a focus on PA.

    Physical activity correlates in people living with HIV/AIDS: a systematic review of 45 studies
    (Taylor&Francis: Disability and Rehabilitation, 2017-03-22) Vancampfort, Davy; Mugisha, James; Richards, Justin; De Hert, Marc; Probst, Michel; Stubbs, Brendon
    Understanding barriers and facilitators of physical activity participation in persons living with HIV/AIDS is an essential first step in order to devise effective interventions. The present review provides a systematic quantitative review of the physical activity correlates in people with HIV/AIDS. Methods: Major electronic databases were searched till August 2016. Keywords included “physical activity” or “exercise” or “sports” and “AIDS” or “HIV”. Results: Out of 55 correlates from 45 studies (N = 13,167; mean age range = 30.5–58.3 years; 63.2% male) five consistent (i.e., reported in four or more studies) correlates were identified. Lower levels of physical activity were consistently associated with older age (6/10 studies), a lower educational level (6/7), a lower number of CD4 cells/μl (7/11), exposure to antiviral therapy (4/6), and the presence of lipodystrophy (4/4). Other important barriers were the presence of bodily pain (2/2), depression (3/3), and opportunistic infections (3/4). Facilitators were a higher cardiorespiratory fitness level (3/3), a higher self-efficacy (2/2), more perceived benefits (2/2), and a better health motivation (3/3). Conclusions: The current review has elucidated that participation in physical activity by people with HIV/AIDS is associated with a range of complex factors which should be considered in rehabilitation programs.
