The hypotheses that certain physical disorders develop with undue frequency among interstate truck drivers and that some of this excess morbidity is due in part to the whole body vibration factor of their job, have been tested by extracting and comparing morbidity data available in the periodic, certification examination records for 3,205 active interstate truck drivers and 1,137 active air traffic controllers. Chi-square tests of the 24 year incidence rates of some medical conditions for two, industry-representative truck driver populations and two, sedentary comparison groups revealed a number of statistically significant differences in group- specific morbidity patterns. Biodynamic strain, microtrauma, and intraluminal/intra-abdominal pressure fluctuations that are known to be produced by truck vibrations have been postulated as being at least partially responsible for the development of certain musculoskeletal, digestive, and circulatory disorders among interstate truck drivers with more than 15 years of service. The combined effects of forced body posture, cargo handling, and improper eating habits along with whole body vibration cannot be ruled out in considering contributory factors for such truck-driver disorders as vertebrogenic pain syndromes, spine deformities, sprains and strains, appendicitis, stomach troubles, and hemorrhoids.
