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 percent. 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/m². The prevalence of diabetes mellitus was 5.6 percent in the overall population and 14.5 percent in hypertensive individuals. Hypertension was a known condition to 74.4 percent of the hypertensive individuals. Among treated hypertensive individuals, 52.4 percent achieved controlled blood pressure and only 34.3 percent 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.
