Associations between HIV infection and frailty status and its individual components: Are frailty components disproportionally affected?

We aimed to examine whether HIV infection was independently associated with frailty status and its individual components. This cross-sectional investigation included people living with HIV (PLWH) and HIV-negative individuals from the baseline survey of the Comparative HIV and Aging Research in Taizhou (CHART) cohort, China. Frailty phenotype was based on five components: weight loss, low physical activity, exhaustion, weak grip strength and slow gait speed. Frailty was defined as the presence of at least three components, and prefrailty was defined as one or two components. Logistic regression models were used to analyse the factors associated with frailty and its components. In all, 2475 people living with HIV (age 45.5 ± 14.9 years; 76.2% male) and 4948 HIV-negative individuals (age 45.5 ± 14.8 years; 76.3% male) were included. Among PLWH, median CD4 count was 395 cells/μL and 78% were currently on antiretroviral therapy (ART). Frailty and prefrailty were significantly more prevalent in PLWH (3.2% vs 1.9% and 32.9% vs 27.9%) overall and at ages 18-39 (1.4% vs 0.2% and 22.7% vs 19.0%), 40-59 (2.5% vs 0.9% and 30.9% vs 27.9%) and 60-90 years (8.4% vs 7.4% and 57.1% vs 45.8%). HIV infection was associated with frailty and prefrailty [adjusted odds ratio (aOR) = 1.48, 95% confidence interval (CI): 1.06-2.08; and aOR = 1.18, 95% CI: 1.05-1.33, respectively] after adjusting for confounding variables, but were strengthened with further adjustment for multimorbidity (aOR = 1.62, 95% CI: 1.14-2.28; and aOR = 1.22, 95% CI: 1.09-1.37), and were no longer significant with further adjustment for depressive symptoms and sleep disorders (aOR = 1.02, 95% CI: 0.71-1.46; and aOR = 1.06, 95% CI: 0.94-1.20). Among individual components, HIV infection was positively associated with weak grip strength and slow gait speed, but negatively associated with low physical activity and exhaustion in all the adjusted models described. Frailty and prefrailty occur more often and earlier in PLWH. However, grip strength and gait speed are affected to a greater extent, highlighting their potential as screening and intervention targets to prevent or slow frailty among PLWH. © 2022 British HIV Association.
