Unsolved issues include whether the increased atherosclerosis burden observed in some studies is attributed to greater prevalence of traditional risk factors or HIV infection. Therefore, we evaluated the association of HIV infection with subclinical atherosclerosis as assessed by carotid artery intima-media thickness, while controlling for the effects of traditional risk factors as operationalised by the Framingham risk score (FRS).MethodsWe did a cross-sectional evaluation of data derived from the baseline assessment of the Comparative HIV and Aging Research in Taizhou (CHART) cohort, an ongoing longitudinal study being done in Zhejiang province, China. HIV-positive and HIV-negative individuals aged 18 years and older were recruited between Feb 1, and Dec 10, 2017, and were frequency-matched for age and sex in a 1:2 ratio. Subclinical atherosclerosis was defined as carotid artery intima-media thickness of 780 μm or higher. Logistic regression was used to assess the associations of HIV-positive serostatus and FRS with subclinical atherosclerosis.Findings480 of 1425 (36·1%, 95% CI 33·6–38·6) HIV-positive and 784 of 2...
