背景资料：关于加拿大人口高血压患病率和管理的现有资料可追溯到1986-1992年，可能并不反映心血管疾病这一主要风险因素的现状。我们试图评估目前的患病率和管理成人高血压在安大略省。方法：潜在的受访者从随机选择的住宅内的目标街区在16个城市进行了联系，在他们的家中，要求参与这项研究。对于同意参与的潜在受访者，使用自动设备测量血压。估计权重用于获得群体参数的代表性估计值。响应加权总成年人口在安大略的7 996 653。结果：从6436个合格的住宅，与4559潜在的参与者，其中2992人同意参加。这些受访者中有2551人（年龄20-79岁）进行了血压测量。高血压定义为收缩压≥ 140 mm Hg，舒张压≥ 90 mm Hg，或接受抗高血压药物治疗，在总体人群中确定为21.3%（男性23.8%，女性19.0%）。患病率随着年龄的增长而增加，从20 - 39岁参与者的3.4%增加到60 - 79岁参与者的51.6%。高血压在黑人和南亚背景的人中比在白色人中更常见;高血压还与较高的体重指数有关。在高血压患者中，65.7%的人正在接受控制高血压的治疗，14.7%的人正在接受治疗但高血压没有得到控制，19.5%的人没有接受任何治疗（包括13.7%的人不知道自己的高血压）。高血压的控制程度并没有显着不同的年龄，性别，种族背景或comorbidity.Interpretation：在安大略，高血压的总体患病率是高的老年人口，但似乎没有增加，在最近几十年。所有年龄组和男女的高血压管理都有明显改善。
Background: Available information on the prevalence and management of hypertension in the Canadian population dates back to 1986-1992 and probably does not reflect the current status of this major risk factor for cardiovascular disease. We sought to evaluate the current prevalence and management of hypertension among adults in the province of Ontario.Methods: Potential respondents from randomly selected dwellings within target neighbourhoods in 16 municipalities were contacted at their homes to request participation in the study. For potential respondents who agreed to participate, blood pressure was measured with an automated device. Estimation weights were used to obtain representative estimates of population parameters. Responses were weighted to the total adult population in Ontario of 7 996 653.Results: From 6436 eligible dwellings, contact was made with 4559 potential participants, of whom 2992 agreed to participate. Blood pressure measurements were obtained for 2551 of these respondents ( age 20-79 years). Hypertension, defined as systolic blood pressure of 140 mm Hg or more, diastolic blood pressure of 90 mm Hg or more, or treatment with an antihypertensive medication, was identified in 21.3% of the population overall ( 23.8% of men and 19.0% of women). Prevalence increased with age, from 3.4% among participants 20 - 39 years of age to 51.6% among those 60 - 79 years of age. Hypertension was more common among black people and people of South Asian background than among white people; hypertension was also associated with higher body mass index. Among participants with hypertension, 65.7% were undergoing treatment with control of hypertension, 14.7% were undergoing treatment but the hypertension was not controlled, and 19.5% were not receiving any treatment ( including 13.7% who were unaware of their hypertension). The extent of control of hypertension did not differ significantly by age, sex, ethnic background or comorbidities.Interpretation: In Ontario, the overall prevalence of hypertension is high in the older population but appears not to have increased in recent decades. Hypertension management has improved markedly among all age groups and for both sexes.
