Abstract
Stroke mortality is associated both with being black and with having low socioeconomic status. However, it is uncertain to what extent that increased risk is related to rates of behavior-related risk factors, such as hypertension, cigarette smoking, obesity, or alcohol consumption. The investigators performed an ecologic analysis to estimate the contributions of behavioral risks, socioeconomic status, and black race to regional variations in stroke mortality rates among persons 55-84 years of age in Florida. They used data from the 1980 census and from the Behavioral Risk Factor Surveillance System (BRFSS) for 1986 through 1988. Weighted multiple linear regression models indicated that regions in Florida with high stroke mortality rates were characterized by high prevalences of poverty, obesity, and hypertension. Although limited by its ecologic design, this study suggests that socioeconomic status and prevalence of behavioral risks contribute independently to interregional disparities in stroke mortality rates in Florida. BRFSS data, now available for more than 45 States, can be used to help clarify the relative contributions of behavioral and other risks to population-based mortality rates.
