Approximately 17% of Canadians with high blood pressure were unaware of their condition, and of Canadians aware of having the condition, approximately 1 in 5 have uncontrolled high blood pressure despite high rates of pharmacotherapy. The objectives of the current study are to estimate the prevalence of resistant hypertension and examine factors associated with (1) lack of awareness and (2) uncontrolled hypertension despite pharmacotherapy.
Using the 2007-2009 Canadian Health Measures Survey (N = 3473, aged 20-79 years) and logistic regression, we quantified relationships between characteristics and (1) presence of hypertension, (2) lack of awareness (among those with hypertension), and (3) uncontrolled high blood pressure (among those treated for hypertension).
Older age, lowest income, and less than high school education were associated with presence of hypertension. Men (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.2) and adults < 60 years (OR, 1.7; 95% CI, 1.1-2.6) were more likely than others to be unaware. Among those aged 60+ years, women were more likely than men to have uncontrolled high blood pressure (OR, 2.4; 95% CI, 1.1-5.2) despite treatment. Elevated systolic blood pressure was the issue in over 90% of women and 80% of men with uncontrolled hypertension. Depending on the definition employed, 4.4% (95% CI, 2.4-6.4) to 7.8% (95% CI, 6.0-9.6) of the population with hypertension had resistant hypertension.
Messaging or interventions encouraging screening may be helpful for all younger Canadian adults and men; programs encouraging blood pressure control may help older women.
大约 17%的加拿大高血压患者不知道自己的病情，而在知道自己患有高血压的加拿大患者中，尽管药物治疗率很高，但大约有 1/5 的患者血压控制不佳。本研究的目的是估计耐药性高血压的流行率，并研究与（1）缺乏意识和（2）尽管进行了药物治疗但血压仍不受控制相关的因素。
使用 2007-2009 年加拿大健康测量调查（N=3473 人，年龄 20-79 岁）和逻辑回归，我们量化了特征与（1）高血压的存在，（2）缺乏意识（在高血压患者中），以及（3）高血压控制不佳（在高血压治疗患者中）之间的关系。
年龄较大、收入最低和受教育程度较低与高血压的存在有关。男性（比值比 [OR]，1.6；95%置信区间 [CI]，1.1-2.2）和<60 岁的成年人（OR，1.7；95% CI，1.1-2.6）比其他人更有可能不知道自己的高血压。在 60 岁以上的人群中，尽管进行了治疗，但女性高血压控制不佳的可能性高于男性（OR，2.4；95% CI，1.1-5.2）。超过 90%的女性和 80%的男性血压控制不佳的问题是收缩压升高。根据所使用的定义，高血压人群中有 4.4%（95% CI，2.4-6.4）至 7.8%（95% CI，6.0-9.6）的患者患有耐药性高血压。
鼓励筛查的信息传递或干预措施可能对所有年轻的加拿大成年人和男性都有帮助；鼓励控制血压的计划可能对老年女性有帮助。
