To analyze the frequency of self-reported systemic arterial hypertension and associated factors.
Study based on data provided by the system of Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL--Telephone-based surveillance of risk and protective factors for chronic diseases), collected in 2006 in Brazil's capitals and Federal District. The frequency of systemic arterial hypertension was estimated in 54,369 adults, stratified by sex, geographic region, sociodemographic and behavioral variables and self-reported morbidities. Crude odds ratios of hypertension were calculated, as well as odds ratios adjusted for the study's variables.
The frequency of self-reported hypertension was 21.6%. It was higher among women (24.4% versus 18.4%), lower in the North and Central-West regions and higher in the Southeast region. The frequency of hypertension increased with age, decreased with level of schooling, was higher among blacks and widowed subjects, and lower among singles. The chance of hypertension, adjusted for confounding variables, was higher in subjects with overweight, diabetes, dyslipidemia and cardiovascular events.
Around one fifth of the population reported suffering from systemic arterial hypertension. The high frequencies of modifiable risk factors indicate the population segments on which intervention should be targeted, aiming to prevent and control hypertension.
分析自我报告的系统性动脉高血压的频率及其相关因素。
本研究基于通过电话调查进行的慢性病风险和保护因素监测系统（VIGITEL）收集的数据，于 2006 年在巴西的首都和联邦区进行。对 54369 名成年人进行了系统性动脉高血压的频率评估，分层变量包括性别、地理区域、社会人口学和行为变量以及自我报告的疾病。计算了高血压的粗比值比，以及调整研究变量后的比值比。
自我报告的高血压患病率为 21.6%。女性（24.4%比 18.4%）高于男性，北部和中西部地区较低，东南部较高。高血压的频率随年龄增长而增加，随教育水平降低而降低，黑人和丧偶者较高，单身者较低。在调整混杂变量后，超重、糖尿病、血脂异常和心血管事件的患者发生高血压的几率更高。
大约五分之一的人口报告患有系统性动脉高血压。可改变的危险因素的高频率表明，应针对这些人群进行干预，以预防和控制高血压。
