employed population in comparson with the non-employed group.
Methods: The study subjects were patients aged 20~65 from 3 university based hospital emergency
centers and a structured questionnaire were used for comparing the characteristics of cardiovascular disease
according to employment status. Multivariate logistic regression was used to analyze the association
between employment status and cardiovascular disease risk factors.
Results: Among the patients, 573 people were employed (482 males, 91 females) and 251 were nonemployed
(117 males, 134 females). Compared to the non-employed group, the employed group was distinctive
in that it contained patients of younger age, had a male dominant gender distribution, and a higher
proportion of smoking and drinking patients. The employed group was less likely to be previouslydiagnosed
with diabetes, hypertension, chronic renal failure, cardiovascular disease, or cerebrovascular
disease. The employed group was generally more stressed out but there was no significant differences in
sleeping time. Infarction was more frequent in the employed group, but hemorrhage was more frequent in
the non-employed group. According to the multivariate logistic regression analysis results, the odds ratio
of drinking and stress was 1.89(95% CI: 1.25~2.86) and 2.68(95% CI: 1.80~3.99) respectively.
Conclusions: Infarction was more frequent in the employed group. Drinking and stress were also more
frequent in the employed group. The results of this study don’t necessarily mean that stress and drinking
are more important than other risk factors but, it means stress and drinking control are more important in
the employed group compared to the non-employed group.
