declined from 2008 to 2012, increased from 2012 to 2015, and resumed declining after 2015. The Hispanic-to-White rate ratio also showed an overall decreasing trend (AAPC=-1.60, P <0.05), with 2010 being the turning point. However, the weighted Index of Disparity showed a significant upward trend (AAPC=1.32, P <0.05). Regarding social determinants, counties with higher social vulnerability had lower degrees of racial disparities in HIV incidence, indicated by lower values of Black-to-White rate ratio ( β =-1.49, P <0.05) and population-weighted disparity index ( β =-39.50, P <0.05). Other county-level characteristics, such as per capita income, population aged 25 years and Persons (age 25+) without a high school diploma, and the proportion of the population not proficient in English, were also associated with higher racial disparities in HIV incidence (P values < 0.05). Conclusions: From 2008 to 2021, racial disparities in HIV diagnosis rates shifted significantly in the U.S. The Black-to-White rate ratio and the Hispanic-to White ratio decreased overall while the population-weighted disparity index increased. Social factors, particularly the Social Vulnerability Index (SVI), were strongly associated with these disparities, highlighting the need for targeted interventions addressing social determinants to reduce HIV racial disparities.
