| Abstrakt: | Background: The available studies have not fully analyzed the several factors involved in the genesis of hypertension (HT), especially the association among blood pressure, urinary sodium excretion and renal dysfunction. Objective: To assess the HT prevalence and risk factors in different age groups in a representative sample of an urban Brazilian population. Methods: The studied population (1717 adult individuals) was evaluated by age groups: 18 to 39 years; 40 to 49; 50 to 59; 60 to 69 and > 70 years. Quantitative variable means and categorical variables of the hypertensive and normotensive groups were compared. Results: The adjusted overall prevalence of HT was 25.23%. The prevalence increased with age and was higher in individuals with low educational level. Increased body mass index and abdominal waist were positively related to a higher prevalence of HT. There was a significant positive association between HT and urinary sodium excretion. Hypertensive individuals presented higher frequency of renal dysfunction, defined as measured creatinine clearance <60 ml/min/m(2). The prevalence of diabetes mellitus was 5.6% in the overall population and 14.5% in hypertensive individuals. Hypertension was a known condition to 74.4% of the hypertensive individuals. Among treated hypertensive individuals, 52.4% achieved controlled blood pressure and only 34.3% of the overall hypertensive patients (treated or not) had blood pressure controlled. Conclusion: This population-based is unique by gathering different demographic, epidemiologic and risk factors involved in the genesis of hypertension in a single sample assessment with a population calculation, which might be extrapolated to other hypertensive populations. |
