Abstract 3887: Declining Stroke Burden Among White and Black Male Veteran Subjects
Background: The prevalence of hypertension and diabetes is increasing. We hypothesized that this could contribute to increasing burden of stroke. We investigated this in a large veteran database for the period from 1991–1997.
Methods: From 10/90–10/97 55,094 veterans were admitted with diagnosis of ischemic stroke (ICD code 434 or 436) at any VA hospital in the country. We extracted demographic data from VA administrative data bases. Discharge ICD-9 codes were used to assess stroke risk factors. Patients with classified as white or black and prevalence of stroke was calculated and stratified according to age.
Results: Overall annual incidence rate fell from 2.7 per 1000 in 1991 to 1.67 per 1000 in 1997. Annual incidence number of stroke declined steadily in both the white and black groups from 1991 to 1997. Incidence numbers fell for all ages with greater decrease in younger age groups.
Conclusion: Despite rising prevalence of vascular risk factors the burden of stroke among male veterans is decreasing. This appears to be true for both blacks and whites and across all age groups.
