Abstract

BACKGROUND: The longer-term risks of statins on physical function among people with HIV are unclear. METHODS: Longitudinal analysis of Multicenter AIDS Cohort Study men between 40 and 75 years of age with ≥2 measures of gait speed or grip strength. Generalized estimating equations with interaction terms between (1) statin use and age and (2) HIV serostatus, age, and statin use were considered to evaluate associations between statin use and physical function. Models were adjusted for demographics and cardiovascular risk factors. RESULTS: Among 2021 men (1048 with HIV), baseline median age was 52 (interquartile range 46-58) years; 636 were consistent, 398 intermittent, and 987 never statin users. There was a significant interaction between age, statin, and HIV serostatus for gait speed. Among people with HIV, for every 5-year age increase, gait speed (m/s) decline was marginally greater among consistent versus never statin users {-0.008 [95% confidence interval (CI) -0.017 to -0.00007]; P = 0.048}, with more notable differences between intermittent and never users [-0.017 (95% CI -0.027 to -0.008); P < 0.001]. Similar results were observed among men without HIV. Significant differences in grip strength (kg) decline were seen between intermittent and never users [-0.53 (95% CI -0.98 to -0.07); P = 0.024] and differences between consistent and never users [-0.28 (95% CI -0.63 to 0.06); P = 0.11] were not statistically significant. CONCLUSIONS: Among men with and without HIV, intermittent statin users had more pronounced declines in physical function compared with consistent and never users. Consistent statin use does not seem to have a major impact on physical function in men with or without HIV.
