To prevent alcohol-related occupational mishaps, employers often conduct background checks on prospective employees for history of driving while intoxicated (DWI) and driving under the influence of alcohol (DUI) to screen out candidates with drinking problems. Few studies, however, have examined the pervasive nature of drinking behavior across activity domains. Based on trauma registry data, we constructed a historical cohort of 120 Maryland residents ages 18 years or older who were injured while riding a bicycle between 1990 and 1997. Driving records for the 120 bicyclists for the 3 years between May 6, 1995 and May 5, 1998 were obtained from the state motor vehicle administration and were analyzed in relation to BAC-positive status at the time of injury. Bicyclists with positive BACs at the time of admission to the trauma center were significantly more likely than those with negative BACs to have a record of license suspension/revocation (52% vs 14%, P < 0.01) and to have DWI/DUI convictions (30% vs 3%, P < 0.01). Despite the modest sample size, this study provides compelling evidence of the pervasive nature of risky drinking between bicycling and driving activities.
