Abstract only Background: We previously reported that persons living in the Stroke Belt were more likely than non-Belt persons to consume ≥2 weekly servings of fried fish but less likely to meet the AHA recommendation of ≥2 weekly servings of nonfried fish. The objective of this report was to evaluate whether the differential consumption of fish contributes to the geographic and racial disparities in stroke. Methods: REGARDS is a national cohort study that recruited 30,239 participants (2003-2007) ≥45 years with oversampling from the southeastern Stroke Belt and African Americans (AAs). Centralized phone interviewers obtained medical histories and in-home examiners obtained physical measures. Dietary data were collected using the self-administered Block98 Food Frequency Questionnaire (FFQ). After excluding the top and bottom 1% of total energy intake, individuals who did not answer 85% or more of the FFQ, and those with a history of stroke or TIA at baseline, the analysis cohort included 20,480 participants. Incident stroke was defined as first stroke occurrence over 5.0 years of follow-up. Results: There were 549 incident strokes including 501 ischemic strokes. After excluding hemorrhagic strokes and stratifying by race, white participants eating ≥2 servings per week (vs
