Alcohol use among Mexican American U.S.-Mexico border residents: differences between those who drink and who do not drink in Mexico.

The predominately Hispanic U.S.-Mexico border population is at an elevated risk for drinking and associated problems due to the area's low SES, poor services infrastructure, and drug-related violence. Among Mexican American residents, recent studies suggest this risk is particularly pronounced among younger age groups, and a key characteristic of this elevated risk involves crossing the border to drink in Mexico (where the legal drinking age is 18). However, few studies have compared the drinking behavior of U.S. residents who consume alcohol on the Mexico side of the border with those who do not. We address this gap in the present study. A multistage household probability sample of 1307 Mexican American border residents was interviewed about their drinking and associated problems over the past year. The survey response rate was 67%. Among current drinkers who reported going to Mexico in the past 12 months (N=468), 36.1% reported consuming alcohol in Mexico. Those who drank in Mexico reported significantly more drinks per week (12.8 versus 8.7, p<.05), were more likely to have binged (58.3% versus 35.4%, p<.001), and were more likely to report one or more alcohol problem (35.5% versus 19.5%, p<.01) than those who did not drink in Mexico. Among those who drank in Mexico, men reported significantly more drinks per day while in Mexico than women (6.2 versus 4.0, p<.001). Male gender and lower income were significant predictors of drinking in Mexico. These findings suggest that drinking in Mexico contributes to the heightened risk for drinking and associated problems seen in previous research among Mexican Americans living on the U.S.-Mexico border.
