Workers exposed to long term, whole body vibration had been shown to have an increase in medical claims for ischemic heart disease, obesity of nonendocrine origin and displacement of intervertebral discs. In order to determine the effect of selection out of jobs on concomitant decreases in claims for ischemic heart diseases, metabolic diseases, bone and joint disease for workers longest exposed to vibration, statistical studies were performed. Approximately 1,376 work histories of workers in vibrated and nonvibrated jobs were analyzed. Logistic analysis was used to control for the effects of age and work experience. There was an association, not statistically significant, between the number of workers with claims for ischemic heart disease, and bone and joint diseases and the number of workers leaving vibrated jobs. No significant association was seen between numbers of workers leaving vibrated vs. nonvibrated jobs. Differential selection influenced to some degree but not totally the pattern of increasing then decreasing morbidity vs work experience. There may be some disease conditions whose onset is hastened by exposure to whole body vibration.
