Socioeconomic inequalities in the incidence, mortality and prognosis of subarachnoid hemorrhage: The FINMONICA Stroke Register

Low socioeconomic status (SES) is associated with increased mortality from stroke, but usually no distinction is made between stroke subtypes. We anal yzed the relationship of SES with mortality and morbidity of subarachnoid h emorrhage (SAH). In the FINMONICA Stroke Register, 956 consecutive SAH even ts were recorded during 1983-1992 in patients aged 25-74 years. We used tax able income stratified into three categories, low, middle, and high, as an indicator of SES. The age-standardized incidence of SAH among men and women aged 25-44 years was approximately three times higher in the low-income gr oup than in the high-income group. In older individuals, differences betwee n the income groups were less pronounced. Among survivors of the acute stag e, a poorer prognosis was observed in patients with low income than in thos e with high income. In conclusion, there is a clear excess mortality and mo rbidity of SAH in young individuals with low income, particularly among men . Copyright (C) 2001 S. Karger AG. Basel.
