Problem And Method:
This study examined the trends in the relative risks for being involved in fatal occupational highway transportation accidents based upon the age and gender of the victim.
Results:
Significant differences in relative risks were identified based upon age; however, there were no significant differences in relative risks based upon gender. The trend analysis of relative risks for all motor-vehicle accidents based upon age showed that males exhibited a significant cubic trend while females exhibited a significant linear trend. The trend analysis of relative risks for fatal motor-vehicle accidents specifically involving vehicle operators based upon age yielded a significant quadratic trend for males and no significant trends for females. Examining the relative risks for fatalities involving only motor-vehicle operators controlled, to a certain extent, the differences in job exposure to motor-vehicle accidents based upon age.
Impact:
Prevention measures are identified as most crucial for older male workers in the transportation and agriculture industries.
