Hypertension represents a serious public health problem and is one of the most frequent causes of morbidity around the world.
To estimate the prevalence of hypertension and its risk factors in a rural community located in the north-eastern state of Minas Gerais, Brazil.
A cross-sectional study was carried out in 2004 in the Virgem das Graças Village, a rural community located the Jequitinhonha Valley. The sample consisted of 287 males and females aged between 18 to 88 years. Hypertension was defined according to Joint National Committee criteria (systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg): subjects already receiving anti-hypertensive treatment were considered to be hypertensive. Bivariate analysis was performed to test the relationship between the independent variables and hypertension. Logistic regression was used to adjust for confounding and to identify interactions. The strength of association was measured using Odds Ratio (OR) and its 95% confidence intervals [CI (95%)].
The crude prevalence of hypertension was 47.0% [CI (95%): 41.1 - 53.0], the age-standardized prevalence was 43.2% [CI (95%): 35.7 - 50.7], while the schooling-standardized prevalence was 44.1% [CI (95%): 43.9 - 44.3]. Age, triglycerides, waist circumference and sex were found to be independent risk factors for hypertension according to multivariate analysis.
The findings provide important evidence concerning the hypertension as a public health problem and its association with dyslipidemia and abdominal obesity in the rural area of Minas Gerais.
高血压是一个严重的公共卫生问题，是全球发病率最高的原因之一。
评估巴西米纳斯吉拉斯州东北部一个农村社区高血压的患病率及其危险因素。
2004年在位于热基蒂尼奥尼亚河谷的农村社区维尔京达斯格拉西亚斯村开展了一项横断面研究。样本包括287名年龄在18至88岁之间的男性和女性。高血压根据美国国家联合委员会标准定义（收缩压>140 mmHg和/或舒张压>90 mmHg）：已经接受抗高血压治疗的受试者被视为高血压患者。进行双变量分析以检验自变量与高血压之间的关系。使用逻辑回归来调整混杂因素并识别相互作用。关联强度使用比值比（OR）及其95%置信区间[CI(95%)]来衡量。
高血压的粗患病率为47.0%[CI(95%)：41.1 - 53.0]，年龄标准化患病率为43.2%[CI(95%)：35.7 - 50.7]，而受教育程度标准化患病率为44.1%[CI(95%)：43.9 - 44.3]。根据多变量分析，年龄、甘油三酯、腰围和性别被发现是高血压的独立危险因素。
这些发现为高血压作为一个公共卫生问题及其与米纳斯吉拉斯州农村地区血脂异常和腹部肥胖的关联提供了重要证据。
