To estimate hypertension prevalence and identify associated socioeconomic, demographic, and anthropometric variables.
A cross-sectional study with probability sampling.
people > or = 18 years of age living in the urban area of Formiga, Minas Gerais state, and registered with the Family Health Program (Programa Saúde da Família-PSF), which covers 94% of the population. Two hundred and eighty-five subjects (131 men and 154 women) were enrolled in the study. Criteria for the diagnosis of hypertension were the following: systolic blood pressure > or = 140 mmHg and/or diastolic blood pressure > or = 90 mmHg, or current use of antihypertensive medication. A standard questionnaire was used to collect socioeconomic and demographic data, as well as information on alcohol consumption, smoking, and physical activity level.
Overall prevalence of hypertension in the target population was estimated at 32.7% (95% CI): 28.2-37.2), 31.7% in men and 33.6% in women. Among subjects with prescribed antihypertensive drugs, 66% reported taking their medication regularly. Hypertension prevalence increased steadily with increasing age (OR = 1.07; 95% CI: 1.05-1.10) and was positively associated with waist circumference (OR = 3.05; 95% CI: 1.49-6.22) and negatively associated with the level of physical activity (OR = 0.45; 95% CI: 0.25-0.82).
Hypertension prevalence was very high in the adult population registered with the PSF in Formiga, representing a major public health problem. Intervention programs that boost physical activity, promote compliance with drug treatment, and focus on hypertensive subjects unaware of their condition are needed.
评估高血压患病率，并确定相关的社会经济、人口统计学和人体测量学变量。
采用概率抽样的横断面研究。
居住在米纳斯吉拉斯州福尔米加市区、年龄≥18岁且在家庭健康计划（Programa Saúde da Família - PSF）登记的人群，该计划覆盖94%的人口。本研究纳入了285名受试者（131名男性和154名女性）。高血压的诊断标准如下：收缩压≥140 mmHg和/或舒张压≥90 mmHg，或目前正在使用抗高血压药物。使用标准问卷收集社会经济和人口统计学数据，以及饮酒、吸烟和身体活动水平的信息。
目标人群中高血压的总体患病率估计为32.7%（95%可信区间：28.2 - 37.2），男性为31.7%，女性为33.6%。在服用处方抗高血压药物的受试者中，66%报告定期服药。高血压患病率随年龄增长稳步上升（比值比 = 1.07；95%可信区间：1.05 - 1.10），与腰围呈正相关（比值比 = 3.05；95%可信区间：1.49 - 6.22），与身体活动水平呈负相关（比值比 = 0.45；95%可信区间：0.25 - 0.82）。
福尔米加PSF登记的成年人群中高血压患病率非常高，这是一个重大的公共卫生问题。需要开展促进身体活动、提高药物治疗依从性以及关注未意识到自身病情的高血压患者的干预项目。
