This article presents a profile of variations in disability-free life expectancy (DFLE) by health region.
Mortality data for 1995 through 1997 are from the Canadian Vital Statistics Database. Estimates of disability (major activity limitations) and sociodemographic characteristics are based on data from the 1996 Census. Supplementary information was provided by the Demography and Geography divisions at Statistics Canada.
DFLE was calculated using a modified version of Sullivan's method. Linear regression using 4 factors representing socio-demographic profiles was used to explain the variation of DFLE by health region. These 4 synthetic variables were determined using principal component analysis.
In 1996, DFLE for both sexes was estimated to be 68.6 years. Estimates by health region varied considerably. Socio-economic status explains a high proportion of the variation of DFLE by health region.
本文介绍了按健康区域划分的无残疾预期寿命（DFLE）的变化情况。
1995年至1997年的死亡率数据来自加拿大生命统计数据库。残疾（主要活动受限）和社会人口特征的估计基于1996年人口普查数据。补充信息由加拿大统计局的人口统计学和地理部门提供。
使用修正版的沙利文方法计算DFLE。使用代表社会人口概况的4个因素进行线性回归，以解释按健康区域划分的DFLE的变化。这4个综合变量是使用主成分分析确定的。
1996年，两性的DFLE估计为68.6岁。各健康区域的估计值差异很大。社会经济地位解释了按健康区域划分的DFLE变化的很大一部分。
