Mortality and morbidity among blue and white collar workers in the Honolulu Heart Program cohort.
There has been a controversy regarding occupation, as defined by blue and white collar work, and coronary heart disease (CHD). In a large long-term prospective study of the Honolulu Heart Program cohort, there were no significant differences between these two occupational classifications and the incidence rates of fatal and non-fatal CHD. Nor were there significant differences in total mortality, stroke or total cancer although there were very small but significant differences in some CHD risk factors. Unlike the previous studies, this investigation was free of prevalent cases of CHD at baseline and controlled for the major risk factors of CHD. We question the utility of using this occupational classification to investigate the causes of CHD.
