Canadian Community Health Survey, 2019-2020: Annual Component

<p>In 1991, the National Task Force on Health Information cited a number of issues and problems with the health information system. To respond to these issues, the Canadian Institute for Health Information (CIHI), Statistics Canada and Health Canada joined forces to create a Health Information Roadmap. From this mandate, the Canadian Community Health Survey (CCHS) was conceived.</p>

<p>The CCHS is a cross-sectional survey that collects information related to health status, health care utilization and health determinants for the Canadian population. The survey is offered in both official languages. It relies upon a large sample of respondents and is designed to provide reliable estimates at the health region level every 2 years.</p>

<p>The CCHS has the following objectives:</p>
<ul><li>Support health surveillance programs by providing health data at the national, provincial and intra-provincial levels</li>
<li>Provide a single data source for health research on small populations and rare characteristics</li>
<li>Timely release of information easily accessible to a diverse community of users</li>
<li>Create a flexible survey instrument that includes a rapid response option to address emerging issues related to the health of the population</li></ul>

<p>The CCHS produces an annual microdata file and a file combining two years of data. The CCHS collection years with both consistent design and consistent population representation can also be combined by users to examine populations or rare characteristics.</p>

<p>The primary use of the CCHS data is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information collected from respondents to monitor, plan, implement and evaluate programs to improve the health of Canadians. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the CCHS results to raise awareness about health, an issue of concern to all Canadians.</p>

1991年，加拿大国家健康信息专项工作组（National Task Force on Health Information）指出了健康信息系统存在的诸多问题与缺陷。为应对这些问题，加拿大健康信息研究所（Canadian Institute for Health Information, CIHI）、加拿大统计局（Statistics Canada）与加拿大卫生部（Health Canada）携手制定了《健康信息路线图》。在此使命驱动下，加拿大社区健康调查（Canadian Community Health Survey, CCHS）应运而生。

加拿大社区健康调查是一项横断面调查，旨在收集加拿大民众的健康状况、医疗服务使用情况及健康决定因素相关信息。该调查支持两种官方语言版本，依托大规模受访样本构建，旨在每两年生成一次健康区域层面的可靠估计值。

加拿大社区健康调查具备以下目标：
- 支持健康监测项目，提供国家级、省级及省内层级的健康数据；
- 为小体量人群及罕见特征相关的健康研究提供单一数据源；
- 及时发布信息，便于多元用户群体便捷获取；
- 打造灵活的调查工具，包含快速响应选项，以应对与民众健康相关的新兴议题。

加拿大社区健康调查会生成年度微数据文件，以及合并两年数据的综合文件。若采集年份的调查设计与人群代表性均保持一致，用户还可将这些年份的数据进行合并，以开展人群或罕见特征相关研究。

加拿大社区健康调查数据的核心用途为健康监测与人群健康研究。联邦及省级卫生与人力资源部门、社会服务机构及其他各类政府机构，会利用受访对象提供的信息，监测、规划、实施并评估旨在提升加拿大人健康水平的项目。多领域研究者会借助该数据开展健康相关研究，以改善民众健康状况。非营利健康组织与媒体则会利用加拿大社区健康调查的结果，提升公众对健康议题的关注度——这是所有加拿大人共同关注的议题。
