Abstract:
The aim of this study was to investigate concurrent tobacco use and binge drinking and the co-occurrence risks of each substance among university students in Africa, Asia, Latin America, and the Caribbean. A cross-sectional survey of 24,753 university students, 58.6% women and 41.4% men, mean age of 20.8 years (SD=2.6) from 30 countries, was conducted in 2013–2015. Five percent of the university students had engaged in concurrent tobacco use and binge drinking, 17.7% in binge drinking only, and 8.0% in current tobacco use only. Overall, among past month tobacco users, 32.1% were frequent binge drinkers, and among binge drinkers, 45.6% werefrequenttobacco users. Compared tostudents who neither smoked nor were binge drinkers, concurrent tobacco users and binge drinkers were more likely to be men (OR=3.09, CI=2.55, 3.74), were older (OR=2.00, CI=1.56, 2.36), had a wealthier family background (OR=1.60, CI=1.30, 1.96), were living in an upper middle or highincome country (OR=0.27, CI=0.10, 0.72), used illicit drugs (OR=3.16, CI=2.64, 3.83), were gambling (OR=2.41, CI=1.91, 3.04), had been in a physical fight (OR=2.08, CI= 1.67, 2.59), had sustained an injury (OR=1.25, CI=1.03, 1.50), and lacked involvement in organized religious activity (OR=0.40, CI=0.32, 0.52). Prevention and treatment strategies should better incorporate the comorbidity of tobacco and alcohol use in their intervention programs.
