Exercise shows strongest effect for quality of life in people with HIV

Exercise emerged as the most effective intervention for overall health-related quality of life (HRQoL) with a standardized mean difference (SMD) of 1.00 (95% confidence interval [0.43, 1.58])—meaning exercise effects were approximately one standard deviation larger than control conditions. Exercise also ranked first for physical domain improvements (SMD = 0.69), psychological wellbeing (SMD = 0.93), and social wellbeing (SMD = 0.57). Mindfulness-based interventions ranked second overall (SMD = 0.82), while cognitive behavioral therapy ranked second for psychological outcomes (SMD = 0.73). The analysis searched ten international databases through August 2025 and used rigorous Cochrane bias assessment tools; however, the authors note that data were insufficient to evaluate effects on environmental, independence, and spiritual domains. Methodological gaps remain: most included trials lacked assessor blinding and standardized measurement tools, and no large-scale head-to-head comparisons directly tested whether exercise outperforms mindfulness or cognitive behavioral therapy in the same population.

The exercise effect size (SMD = 1.00) was notably larger than mindfulness (SMD = 0.82) and cognitive behavioral therapy for overall HRQoL—a clinically meaningful difference suggesting exercise uniquely addresses physical fitness, mood, and social engagement simultaneously. Physical domain improvement (SMD = 0.69) may reflect increased cardiovascular capacity and reduced fatigue, both common concerns in HIV populations; psychological gains (SMD = 0.93) were proportionally larger, suggesting exercise influences mood and anxiety as much as physical function. The second-place ranking for mindfulness-based interventions indicates complementary benefit—some trials combined mindfulness with exercise or used it alone, and the ~0.18-point gap from exercise may reflect different mechanisms: exercise improves fitness and energy, while mindfulness builds stress resilience and acceptance. The analysis did not stratify by exercise type (aerobic, resistance, mixed) or duration, so the optimal "dose" remains unknown. The reviews' reliance on SMD rather than disease-specific endpoints (CD4 count stability, hospitalization rates) means the findings reflect subjective wellbeing measures rather than clinical outcomes; future research must clarify whether improved HRQoL correlates with better medication adherence or immune outcomes.
