Systemic Arterial Hypertension (SAH), considered a public health problem due to its high prevalence and difficult control, is also described as one of the most important risk factors for cardiovascular diseases.
This study aimed to determine the prevalence of SAH, as well as characteristics related to its control and treatment, among individuals aging between 18 and 90 years from the urban region of Nobres, MT.
Cross-sectional, population-based study, with random sampling and with replacement. For classification of SAH, criteria included blood pressure (BP) > or =140/90 mmHg or current use of antihypertensive drugs. Individuals were interviewed with standardized questionnaires previously tested. Variables were described as means +/- standard deviations and frequencies. Means were compared with the Student s t test and associations were determined with the Pearson chi-square test, with a significance level of 5%.
SAH has a prevalence of 30.1% in the sample, composed of 1,003 individuals older than 18 years. Among hypertensive individuals (N = 302), 73.5% knew about their condition, 61.9% were under treatment and for 24.2% the BP was under control. A positive association was observed between SAH and age; illiteracy; less than 8 years education; BMI > or = 25 kg/m(2); high and very high waist circumference; waist-hip ratio (WHR) at risk level; sedentariness; and alcoholism.
This study showed that SAH represents an important public health problem even in a small district in the interior region of Brazil. Levels of control and treatment of hypertension in the population were higher than those observed in similar studies, but were considered not satisfactory.
全身性高血压（SAH）由于其高患病率和难以控制，被认为是一个公共卫生问题，同时也是心血管疾病最重要的危险因素之一。
本研究旨在确定来自 MT 州诺布雷什市城区年龄在 18 至 90 岁之间的个体中 SAH 的患病率，以及与控制和治疗相关的特征。
这是一项横断面、基于人群的研究，采用随机抽样和有放回的方法。为了对 SAH 进行分类，标准包括血压（BP）>或=140/90mmHg 或正在使用抗高血压药物。使用预先经过测试的标准化问卷对个体进行访谈。变量以平均值+/-标准差和频率来描述。平均值通过学生 t 检验进行比较，通过 Pearson 卡方检验确定关联，显著性水平为 5%。
在该样本中，SAH 的患病率为 30.1%，共有 1003 名年龄超过 18 岁的个体。在高血压患者（N=302）中，73.5%的人知道自己的病情，61.9%的人正在接受治疗，24.2%的人的血压得到了控制。SAH 与年龄、文盲、受教育年限少于 8 年、BMI>或=25kg/m2、高和极高腰围、处于风险水平的腰围-臀围比（WHR）、久坐不动和酗酒呈正相关。
本研究表明，即使在巴西内陆的一个小地区，SAH 也是一个重要的公共卫生问题。与类似研究相比，该人群的高血压控制和治疗水平较高，但仍不理想。
