[Time of adhesion to the Family Health Strategy protects elderly against cardiovascular and cerebrovascular accidents in Florianópolis, 2003 to 2007].

The Family Health Strategy (FHS) provides longitudinal follow-up and integrated healthcare. This study evaluated the influence of the time of adhesion to the FHS upon the incidence of cardiovascular and cerebral vascular accidents among the elderly enrolled in the CASSI-Florianópolis. The events were selected because of their high incidence, good notification and association with risk factors the FHS is able to modify. The longer the time of adhesion to the strategy the lower the incidence of these events, demonstrating the effectiveness of the FHS. A historical cohort study was conducted with 674 senior participants (60 or more years), registered between November/2003 and March/2007. The analysis used Student's T test, bivariate and multivariate analysis with logistic regression. The independent risk factors were: age over 80 years, (OR=3,44; CI 95%: 1,8-6,2), diabetes (OR=2,62; CI 95%: 1,4-4,7), hypertension (OR=1,68; CI 95%: 1,0-2,6) and physical inactivity (OR=2,06; CI 95%: 1,2-3,2). The study found no significant association between gender, dislipidemia, obesity, smoking, alcoholism and the studied events. The long time of adhesion to the FHS showed independent protective effect (OR=0,43; CI 95%: 0,2-0,8) after adjustment to earlier covariates, being effective in reducing the incidence of cardiovascular and cerebral vascular accidents among the enrolled population of elderly.
