Prevalencia da pré-hipertensão arterial associada aos fatores de risco cardiovascular

Abstract

: The study of prehypertension (PH) is still incipient in the scient i fic environment, however, it is of great importance in the identification and early prevention of individuals more likely to progre ss to more advanced stages of SAH and, therefore, more predisposed to development of target organ lesions. Objectives : To evaluate the prevalence of PH associated with risk factors of different age groups, in a representative sample of the population of Sã o José do Rio Preto , SP Casuistry and Method : A total of 1,717 adult individuals from an urban population of a medium sized city were studied, divided into age groups, evaluating demographic, epidemiological and biochemical characteristics, associating th emselves with risk factors present in this population. Results: The prevalence of corrected pre hypertension for the population was 22.9%. PH progressively decreased significantly according to population aging. Women are more likely to be pre hypertensive than men (46.8% versus 41.9%) and, consequently, to progress from PH to SAH. The prevalence of prehypertensive individuals was higher than 20% in all assessed categories of education; however, individuals with less school education have a higher risk of pr ogressing to SAH. There was a positive and significant association between PH, BMI and WC. Regarding physical activity, 47.5% of hypertensive individuals were considered to be inactive or with little physical activity, while 38.8% practiced more than 150 m inutes / week. For biochemical variables, there were statistically significant differences in relation to glycemia and glomerular filtration rate, factors that increased the prevalence of PH. Conclusions: This study has associate d several risk factors asso ciated with the development of SAH, through the comprehensive analysis of PH as a future predictor of SAH.
