Why such a vast variation in statistics? The reason likely lies in the way researchers arrived at their estimates.
“Until now, all leading estimates were based not on actual measures of college student data but rather on the assumption that college student drinking and driving fatality rates were the same as the general population,” says James C. Turner, MD, executive director of UVA Student Health and lead author of the study, which appears in the January-March 59 (4) issue of the Journal of American College Health (JACH).
But Turner’s study looks directly at college students as a distinct population group. He and UVA colleagues analyzed survey results from two-thirds of Virginia colleges and universities with membership in the American College Health Association (ACHA), the nation’s leading professional college health association. Twenty-four institutions of higher education in Virginia are ACHA members.
The incident rates found by Turner’s team were between 1.7 and 4.3 deaths per 100,000 college students, while previous estimates ranged from 14.1 to 15.2 deaths per 100,000.
“It’s hard to believe leading statistics aren’t derived from any collected data of actual college student drinking and driving incidents or resulting deaths,” says Turner. “Previous estimates merely involved the comparison of national traffic accident reports and college enrollment as a proportion of census data. It’s quite a leap to assume that college student health and behavior is the same as the general public.”
“Our study clearly demonstrates the need to collect more reliable statistics based on actual outcomes in the college population, but more importantly it suggests that college students in Virginia suffer far fewer alcohol-related traffic deaths than the general population” says Turner, the immediate past president of ACHA. “There are many factors that likely contribute to lower alcohol-related vehicular fatality rates among college students. It’s important to better understand what factors contribute to the benefit and protection afforded by alcohol education and/or the campus environment.”
Turner and UVA colleagues are in the midst of conducting a national study using the same methodology and anticipate results within the year.
