Alcohol use and problems in daily and non-daily coffee drinking college females

ABSTRACT

Background: For more than a decade, a large proportion of research on caffeine use in college students has focused on energy drinks (ED), demonstrating an association between ED consumption and heavy/problem alcohol use. The present study examined the relationship between daily coffee (DC) consumption and varied measures of alcohol use and problems in a sample of college women. Methods: Participants were undergraduate females (N = 360) attending an urban university in 2001–02 and prior to the rise in ED popularity on college campuses. Analyses compared women who reported drinking coffee daily (DC; 16.9%), to women who did not (non-daily coffee [NDC]; 83.1%) on standardized measures of alcohol use and problems. Results: For both past month and year of drinking, DC women generally reported consuming more alcohol and were 2.1–2.6 times more likely to screen at risk for alcohol problems than their NDC counterparts. DC women were also more likely than NDC women to report problems related to drinking (e.g., experiencing blackouts, inability to stop drinking after they had started). Conclusions: Findings support potential benefits of health education and screening that goes beyond EDs, focusing on varied forms of caffeine consumption.
