Abstract:

Objective: To estimate the prevalence of cognitive impairment and analyze its association with blood pressure control in elderly hypertensive individuals. Method: Cross-sectional study conducted with 383 elderly hypertensive individuals in the state of Piauí, Brazil. Sociodemographic and clinical data were collected, blood pressure was measured and cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) test. Poisson regression with robust variance was used. Results: The prevalence of cognitive impairment was 74.4%, being higher in the age group aged 80 years or over and among those with less education. The prevalence of uncontrolled blood pressure was 61.6%, with a higher proportion among elderly people with cognitive impairment. There was an association between cognitive impairment and uncontrolled blood pressure (Adjusted PR: 5.13; 95%CI=3.25-8.09). Conclusion: The significant association between cognitive function and blood pressure control suggests that cognitive impairment is an important risk factor for uncontrolled blood pressure in elderly people. The inclusion of screening measures for possible cognitive deficits may be useful to better monitor the rise in blood pressure levels among hypertensive elderly people.
