Relationship Between Whole Body Vibration and Morbidity Patterns Among Heavy Equipment Operators.

PB267451

Publication Date	1974
Personal Author	Milby, T. H.; Spear, R. C.
Page Count	86
Abstract	For the morbidity survey among Northern California heavy construction machine operators, approximately 3,900 claims for medical services were collected from August 1971 to March 1973, and statistically analyzed. The study design and data handling are set out. It is concluded that there is no evidence of higher age-adjusted morbidity rates among men exposed to whole body vibration than in the control group. But there is evidence of a selection process in which exposed men leave jobs when they become afflicted with certain diseases, such as ischemic heart disease, musculoskeletal diseases and obesity of non-endocrine origin.
