Prevalence of stroke in Finland.
The prevalence of stroke was investigated in a Finnish population study. The results were based on cross-sectional data from a follow-up examination of a prospective study conducted in 1973-1976. The study population drawn from four regions of the country comprised 11,103 men and 11,096 women aged 20 years and over. The age-adjusted prevalence of stroke was 10.3/1000 in men and 5.8/1000 in women. The prevalence was significantly higher in non-attendants at the examination than in attendants. In 15 per cent of the prevalence cases the stroke was caused by subarachnoid hemorrhage, in six per cent by cerebral hemorrhage and in the remainder by cerebral infarction or the type could not be specified. Over half (57 per cent) of the survivors of stroke had no or only slight disability; eight per cent were totally disabled. Some form of organic heart disease and hypertension was significantly more common in the prevalence cases than in the others.
