Data from the 1990 Ontario Health Survey were used to investigate the
association of socioeconomic status with the likelihood of meeting cur
rent recommendations for four health behaviours (smoking, fat intake,
alcohol consumption, and physical activity level) in adults living in
Ontario (Canada), Health behaviours were categorised as 'unhealthy' if
they did not meet current recommendations in Ontario (smoking, fat in
take > 30% of dietary energy, alcohol intake > 14 units per week, low
level of leisure-time physical activity). Two summary variables based
on the number of 'unhealthy' behaviours were also examined: the crude
number of 'unhealthy' behaviours reported and the likelihood of report
ing 3 or 4 'unhealthy' behaviours. Four measures of socio-economic sta
tus were used: educational achievement, household income status, sourc
e of household income, and occupational prestige. Multiple logistic an
d linear regression analyses were performed to explore the association
of each 'unhealthy' behaviour and of the summary variables with socio
-economic status indicators (taken independently or simultaneously), c
ontrolling for demographic characteristics. Except for the positive re
lationship between income status and high alcohol intake, measures of
'unhealthy' behaviours were inversely associated with the socio-econom
ic indices, suggesting that individuals in lower socioeconomic groups
are at an increased risk for health problems.
