[Epidemiology of cerebrovascular diseases in Sabaneta, Colombia (1992-1993)].
OBJECTIVE
In Columbia the epidemiology of cerebrovascular illness (ECV) is unknown. For this reason a study was made to determine the prevalence, incidence and annual mortality, and to identify the different types of ECV and the demographic characteristics of the population.


METHODS
In the urban area of Sabaneta, Columbia 13,588 door to door interviews were carried out among the inhabitants. A cutoff study carried out between April and June 1992 showed the prevalence of ECV. One year follow-up of persons without ECV between June 1992 and June 1993, enabled the incidence and annual mortality to be evaluated. A structured interview was used to identify the demographic characteristics of the population and classify people as healthy or as possibly having ECV. The latter were examined by neurologists to confirm or rule out the presence of ECV and to determine the type of ECV involved. Of the total urban population, 76.9% agreed to participate in the study. During the follow-up year, 8.4% were lost trace of.


CONCLUSIONS
The prevalence of ECV was 559.3/ 100,000 inhabitants, increasing with age (15). In the 15-40 year old group, the incidence of ECV was 44 times higher in women than in men. The annual incidence rate was 88.9/100,000 inhabitants: thromboembolic disease was the most frequent. Of a total of 87 cases of ECV, 12 (13.98%) died of various causes during the year in which they were being observed. The annual mortality rate for ECV was 16.2/100,000 inhabitants, all being primary cases.
