Rosenberg ES, et al. - Researchers estimated rates of living with an HIV diagnosis (2013) and new diagnosis among men who have sex with men (MSM) (2014) by state and race using a recently developed model for estimating state-level population sizes of MSM by race that synthesizes data from the American Community Survey and the National Health and Nutrition Examination Survey, in conjunction with CDC-based HIV diagnosis data. Results suggested more prominent racial disparities in HIV infection among MSM than geographic ones. They thereby recommended interventions to be differentially tailored to areas of high proportionate and absolute burden.
