Black Americans have a higher incidence of cerebral venous thrombosis (CVT) compared with other races, according to a study published online Aug. 26 in Neurology.
Fadar Oliver Otite, M.D., from the State University of New York Upstate Medical University in Syracuse, and colleagues identified all new cases of CVT in the State Inpatients Database of New York and Florida for 2006 to 2016 in a retrospective cohort study.
The researchers found that the annual age- and sex-standardized incidence of CVT in cases/million population varied from 13.9 to 20.2 from 2006 to 2016, but there was variation in incidence by sex (women: 20.3 to 26.9; men: 6.8 to 16.8) and age/sex (women aged 18 to 44 years: 24.0 to 32.6 percent; men aged 18 to 44 years: 5.3 to 12.8 percent). There was also variation in incidence by race (Blacks: 18.6 to 27.2; Whites: 14.3 to 18.5; and Asians: 5.1 to 13.8). Across 2006 to 2016, the incidence increased, but this was mainly driven by increases in men of all ages (combined annualized percentage change [APC], 9.2 percent), women aged 45 to 64 years (APC, 7.8 percent), and women aged ≥65 years (APC, 7.4 percent). There was no change observed in incidence among women aged 18 to 44 years.
“Our findings need to be replicated in other multi-ethnic studies in order to better understand the etiological reasons for this changing trend,” the authors write.
