Beneficial hispanic stroke mortality: An exploration of potential explanatory factors
type: CreativeWork
description: Stroke mortality rates are reported to be lower for Hispanics than non-Hispanic Whites. This project investigates factors that contribute to this lower rate in three ways: 1) examine the role of immigrant status in stroke incidence and mortality, 2) investigate the impact of cause of death ambiguity, and 3) examine the role of misreport of ethnicity on death certificates. \r\nIn examining the effect of immigrant status I used the Hispanic Established Populations for the Epidemiologic Study of the Elderly (EPESE) and the East Boston EPESE. This research compares baseline health characteristics of immigrants with native-born respondents. Additionally, I examine differences in stroke mortality, as well as the risk of stroke between waves. In both EPESE samples significant differences in demographics and co-morbidities existed at baseline between immigrants and the US born. However, the odds of stroke mortality or having a stroke during follow-up were not significantly different for immigrants and the US born in either the East Boston or Hispanic data. \r\n To examine the impact of cause of death coding and misreport of ethnicity on death certificates, I used national vital registration data for the years 1989-1991 and 1999-2002, including foreign and US born Hispanics and non-Hispanic Whites. Hispanic deaths were adjusted for misclassification of ethnicity on the death certificate. These data were linked to census estimates and 5% census samples for the corresponding time periods, allowing for estimates of the foreign born population. Adjustment for nativity and death certificate misclassification removed the stroke mortality advantage for US born Hispanic men, but not women. After adjustment, US born Hispanic men and women have higher rates of mortality from subarachnoid stroke than Whites (RR 1.27 and 1.27 respectively), but lower rates of mortality from Ischemic (RR 0.85 and 0.79 respectively) and chronic effects of stroke (RR 0.95 and 0.79 respectively). \r\n These…
