Abstract(s)
Objectives : This study describes the health-related quality of life(HRQOL) of the Portuguese working age population and investigates
sociodemographic differences.
Methods : Subjects randomly selected from
the working age population ( n =2,459) were
assessed using the SF-36v2 and converted
into the preference-based SF-6D.
Results : The mean SF-6D utility value was
0.70 (range 0.63–0.73). The mean utility
value was lower for the lower educational
level than for the highest. Women, people
living in rural areas and older adults
reported lower levels of utility values.
Non-parametric tests showed that health
utility values were signifi cantly related to
employment; unskilled manual workers
reported utility values lower than
non-manual workers. For different
diseases, mean utility values ranged
from 0.58 (sexual diseases) to 0.66
(hepatic conditions). Cluster analysis
was adopted to classify individuals into
three groups according to their answers
to the SF-6D dimensions. Multinomial
logit regression was used to detect
sociodemographic characteristics affecting
the probability of following each cluster
pattern. This study yielded normative data
by age and gender for the SF-6D.
Conclusions: The authors conclude that SF-6D
is an effective tool for measuring HRQOL
in the community so that different
population groups can be compared.
The preference-based measure used
seems to discriminate adequately across
sociodemographic differences. These
results allow a better understanding of the
impact of sociodemographic variables on
the burden of illness perception.
