Background: This study examined health-related quality of life in a general
population in relation to different socioeconomic variables. Method: The s
tudy was cross-sectional and was conducted in Uppsala county, Sweden, which
had approximately 290,000 inhabitants in 1995. The study was based on a se
lf-administered postal questionnaire sent to a random sample of 8,000 inhab
itants aged 20-84 years, with a response rate of 68%. Health-related qualit
y of life was measured on a 0 (dead) to 1 (full health) cardinal scale by t
wo methods used to measure health-state utilities in economic evaluations,
i.e. the rating scale method and the time trade-off method. Results: The me
an age was 46 years and approximately 54% were women. Almost 70% were marri
ed or cohabiters. Approxiamtely 33% of the respondents had less than high-s
chool education and 26% had a university degree. The mean income was SEK 13
,000 per month and the proportion unemployed was 4.5%. The proportions of b
lue-collar workers, white-collar workers and self-employed were 40, 50 and
10% respectively. With the rating scale method, the mean health-state utili
ty decreased from 0.86 in the youngest age group (20-29 years) to 0.63 (80-
years) in the oldest age group and from 0.94 to 0.61 with the time trade-o
ff method. Quality of life increased with income, education and social grou
p and decreased with being single and unemployed. Conclusion: These methods
are useful in assessing health-related quality of life in the general popu
lation and that quality of life varies substantially among different socioe
conomic groups.
