To describe the methods used in nine provincial surveys carried out as part of the Canadian Heart Health Initiative.
Population-based cross-sectional surveys, following a core standardized protocol, implemented by provincial departments of health in collaboration with Health and Welfare Canada. Data were obtained through a home interview and a clinic visit. A standard manual of field operations and standardized training procedures were used in all provinces.
Nine Canadian provinces during the period 1986 to 1990.
A probability sample of 26,293 men and women aged 18 to 74 years was selected from the health insurance registries in each province. Over 30% of the participants had post-secondary education. About 50% were 18 to 34 years old.
Data on sociodemographic characteristics, hypertensive and diabetic status, knowledge and awareness of the causes and consequences of cardiovascular disease and two blood pressure measurements were obtained in a home interview. During a clinic visit, data were collected on height, weight (waist and hip circumferences in four provinces), two blood pressure measures and a blood sample. Total plasma cholesterol, triglycerides and high- and low-density lipoprotein cholesterol were measured in the Lipid Research Laboratory, University of Toronto and St. Michael's Hospital.
Of the subjects invited to participate in the survey, 78% were interviewed, 69% attended the clinic and 64% provided a fasting specimen (8 hours or more). The response rates were slightly lower for men aged 18 to 34, for women aged 65 to 74 and for those with fewer years of education. Data from the provincial surveys (Ontario will complete the survey in 1992) are being compiled in the Canadian Heart Health Database.
The process followed in the implementation of the provincial heart health surveys is a model of how provincial departments of health may carry out epidemiologic investigations in support of their mandate. The approach illustrates how a country-wide database can be built through partnerships among different levels of government. The use of community health nurses was instrumental in the efficient implementation of the surveys and in the realization of the relatively high rates of response attained.
描述作为加拿大心脏健康倡议一部分开展的九项省级调查所采用的方法。
基于人群的横断面调查，遵循核心标准化方案，由省级卫生部门与加拿大健康与福利部合作实施。数据通过家庭访谈和诊所就诊获取。所有省份均使用标准的现场操作手册和标准化培训程序。
1986年至1990年期间的加拿大九个省份。
从每个省份的健康保险登记册中选取了26293名年龄在18至74岁之间的男性和女性作为概率样本。超过30%的参与者接受过高等教育。约50%的人年龄在18至34岁之间。
在家庭访谈中获取社会人口学特征、高血压和糖尿病状况、对心血管疾病病因及后果的知晓情况以及两次血压测量的数据。在诊所就诊期间，收集身高、体重（四个省份测量腰围和臀围）、两次血压测量值和一份血样的数据。在多伦多大学和圣迈克尔医院的脂质研究实验室测量总血浆胆固醇、甘油三酯以及高密度和低密度脂蛋白胆固醇。
受邀参与调查的受试者中，78%接受了访谈，69%前往诊所就诊，64%提供了空腹样本（8小时或更长时间）。18至34岁的男性、65至74岁的女性以及受教育年限较少的人群的回应率略低。省级调查（安大略省将于1992年完成调查）的数据正在汇编入加拿大心脏健康数据库。
省级心脏健康调查的实施过程是省级卫生部门如何开展流行病学调查以支持其任务的一个典范。该方法说明了如何通过不同层级政府之间的合作建立一个全国性数据库。社区健康护士的使用有助于高效实施调查并实现相对较高的回应率。
