Impact of selected risk factors on quality-adjusted life expectancy in Denmark (original) (raw)

Scandinavian Journal of Public Health, 2007

Abstract

Aims: The construct quality-adjusted life years (QALYs) combines mortality and overall health status and can be used to quantify the impact of risk factors on population health. The purpose of the study was to estimate the impact of tobacco smoking, high alcohol consumption, physical inactivity, and overweight on QALYs. Methods: Life tables for each level of exposure to the risk factor were constructed mainly on the basis of the Danish National Cohort Study. QALYs were estimated for exposed and unexposed by Sullivan's method, by combining life tables, EQ-5D self-classified health status from the Danish Health Survey 2000, and Danish EQ-5D values. Results: The quality-adjusted life expectancy of 25-yearolds was 10—11 QALYs shorter for heavy smokers than for those who never smoke. The difference in life expectancy was 9— 10 years. Men and women with high alcohol consumption could expect to lose about 5 and 3 QALYs, respectively. Sedentary persons could expect to have about 7 fewer...
