Based on estimates of activity restriction from the Canada Health Survey, institutional data on long-term care, and survival data from vital statistics, we have calculated an index of health expectancy (life expectancy in each state of health), and a summary of these indices which we have called quality-adjusted life expectancy. At birth, expected years of long-term institutionalization were 0.8 for men and 1.5 for women. Expected years of activity restriction not involving long-term institutionalization were 10.8 for men and 14.0 for women; 3.0 of the expected years of activity restriction for men and 1.3 of these years for women were in the most severe category of restriction (unable to do major activity). For both sexes together, quality-adjusted life expectancy was 1.4 years greater in Ontario and the Prairies than in the Atlantic region, 3.2 years greater in Canada's three largest cities than in rural areas and small towns, and 7.7 years greater among persons from high-income families than among persons from low-income families.
根据加拿大健康调查得出的活动受限估计数据、长期护理机构数据以及人口动态统计中的生存数据，我们计算了健康期望指数（处于每种健康状态下的预期寿命），并对这些指数进行了汇总，我们将其称为质量调整生命预期。出生时，男性长期入住机构护理的预期年数为0.8年，女性为1.5年。不涉及长期机构护理的活动受限预期年数，男性为10.8年，女性为14.0年；男性活动受限预期年数中有3.0年、女性中有1.3年属于最严重的受限类别（无法进行主要活动）。就男女总体而言，安大略省和草原地区的质量调整生命预期比大西洋地区长1.4年，加拿大三大城市比农村地区和小镇长3.2年，高收入家庭人群比低收入家庭人群长7.7年。
