[The proportional mortality ratios of specific-cause mortality by occupation and education among men aged 20-64 in Korea (1993-2004)].
OBJECTIVE
This study investigated the relationship of occupational class and educational background with proportional mortality ratios in Korea.


METHODS
Mortality was investigated using the entire registered death data from 1993 to 2004, obtained from the Korean National Statistics Office. Proportional mortality ratios (PMRs) for specific diseases were calculated according to the occupational class and educational background of men aged 20-64.


RESULTS
Manual workers were found to have higher PMRs for liver disease and traffic accidents, as did the lower educated group. Especially, this study showed trends of an increasing of the wide gap between lower and higher socioeconomic stati for liver disease, traffic accidents, diabetes mellitus and cerebral vascular disease. The mortality for cerebrovascular disease, diabetes mellitus, heart disease, traffic accident and liver disease showed increasing trends according to the calendar year for the lower than the higher social class.


CONCLUSIONS
The specific conditions that had higher PMRs in the Korean lower social class were liver disease and traffic accidents. Especially, there was an increasing trend for a widening of the gap between manual and non-manual groups in relation to mortality from liver disease, diabetes mellitus and traffic accidents.
