Area-based measures of socio-economic status are increasingly used in population health research. Based on previous research and theory, the Canadian Marginalization Index (CAN-Marg) was created to reflect four dimensions of marginalization: residential instability, material deprivation, dependency and ethnic concentration. The objective of this paper was threefold: to describe CAN-Marg; to illustrate its stability across geographic area and time; and to describe its association with health and behavioural problems.
CAN-Marg was created at the dissemination area (DA) and census tract level for census years 2001 and 2006, using factor analysis. Descriptions of 18 health and behavioural problems were selected using individual-level data from the Canadian Community Health Survey (CCHS) 3.1 and 2007/08. CAN-Marg quintiles created at the DA level (2006) were assigned to individual CCHS records. Multilevel logistic regression modeling was conducted to examine associations between marginalization and CCHS health and behavioural problems.
The index demonstrated marked stability across time and geographic area. Each of the four dimensions showed strong and significant associations with the selected health and behavioural problems, and these associations differed depending on which of the dimensions of marginalization was examined.
CAN-Marg is a census-based, empirically derived and theoretically informed tool designed to reflect a broader conceptualization of Canadian marginalization.
基于社会经济地位的区域指标在人群健康研究中得到了越来越多的应用。根据以往的研究和理论，加拿大边缘化指数（CAN-Marg）被创建出来，以反映边缘化的四个维度：居住不稳定、物质匮乏、依赖和种族集中。本文的目的有三：描述 CAN-Marg；说明其在地理区域和时间上的稳定性；描述其与健康和行为问题的关系。
使用因子分析，在 2001 年和 2006 年的普查年份，在传播区域（DA）和普查地段层面创建 CAN-Marg。从加拿大社区健康调查（CCHS）3.1 和 2007/08 的个人数据中选择了 18 个健康和行为问题的描述。在 DA 层面（2006 年）创建的 CAN-Marg 五分位数被分配给个人 CCHS 记录。采用多水平逻辑回归模型检验边缘化与 CCHS 健康和行为问题之间的关系。
该指数在时间和地理区域上表现出显著的稳定性。边缘化的四个维度都与所选的健康和行为问题之间存在很强且显著的关联，而且这些关联因所研究的边缘化维度而异。
CAN-Marg 是一种基于普查的、经验性的、理论上的工具，旨在反映加拿大更广泛的边缘化概念。
