Older People Living with HIV Were Less Physically Active Than Their Uninfected Counterparts in China: A Matched-Sample Mediation Analysis.

The study compared the level of physical activity (PA) between older people living with HIV (PLWH) and their HIV-negative counterparts in China and tested the mediational roles of self-compassion, attitudes toward aging, and perceived stress in the between-group difference in PA. From December 2017 to August 2018, face-to-face interviews were conducted among 337 and 363 HIV-positive and -negative people aged ≥ 50 in Yongzhou City, Hunan, China. Path analysis was performed. The proportions of low, moderate, and high levels of PA in the HIV-positive and -negative groups were 18.9% versus 6.7%, 43.1% versus 32.0%, and 38.0% versus 61.3%, respectively, yielding a statistically significant difference. The path analysis showed that older PLWH reported less self-compassion and positive attitudes toward aging, which was in turn associated with more perceived stress and ultimately associated with less PA. Chinese older PLWH were more sedentary than their HIV-negative counterparts. Future PA interventions may modify the mediators.
