Quality of life (QOL) of older people is
becoming an important public health concern
and should be evaluated. The aim of this study
was to evaluate socioeconomic and individual
determinants of QOL of older subjects living in
metropolitan Santiago, Chile. We first carried
out a qualitative phase with focus groups of
older people. According to the conclusions of
the focus groups, a questionnaire about QOL
was devised and added to the WhoQoL (World
Health Organization Quality of Life) and
WHOQoL-Old brief questionnarires. The final
document with 85 questions was applied to
healthy older subjects living in the community.
A total of 1,676 subjects aged 71.8±7.4 years
(1,189 women) took part in the survey. A multiple
stepwise regression model showed that a
higher socioeconomic level, a better educational
level, performing voluntary work, having
a partner, participating in groups with other
older people, and being younger were factors
independently associated with a higher QOL. A
principal components analysis showed that
psychological health and social relationships
were the main domains that explained the
total quality of life score. Psychological health
and social relationships were the main determinants
of QOL in this sample of older Chilean
people living in metropolitan Santiago.
