Abstract

OBJECTIVES
This study aims to find differences that reflect the magnitude of health disparities in wage workers in Korea according to income index(personal income, household income, equivalized income) by gender.
METHODS
Data was obtained from the 11th wave of Korean Labor and Income Panel Survey in 2008. This study analyzed 4,205 subjects(2,570 males and 1,635 females) aged 19-65 years. To compare the health effects of each income index by gender, unconditional multiple logistic regression, health-related behaviors, and working conditions were used. The unconditional multiple logistic regression was adjusted by socio-demographic characteristics. All statistics were estimated using SAS survey procedures.
RESULTS
According to unconditional multiple logistic regression, significant differences in ORs between men and women were observed in this study for those wage workers who self-rated their health status to be poor. This was consistent between each income index. Men had an OR of 1.76 (95% CI, 1.28~2.43) by personal income, 1.70 (95%CI, 1.25~2.32) by household income and 1.69 (95% CI, 1.23~2.31) by equivalized income. Women had an 2.09 (95% CI, 1.47~2.97) by household income and OR of 1.95 (95% CI, 1.36~2.79) by equivalized income, but personal income did not have a significant effect on OR for women.
CONCLUSIONS
The study of occupational and environmental medicine should consider that each income index has different effects on the self-rated health status according to gender. Household income index and equivalized income index would represent a health status for women.
