Association between Acculturation and Binge Drinking among Asian-Americans: Results from the California Health Interview Survey

Objective. Evaluate the association between acculturation and binge drinking among six Asian-American subgroups. Methods. A cross-sectional analysis of public access adult portion of 2007, 2009, and 2011/2012 California Health Interview Survey data was conducted. Univariate and multivariable logistic regression analyses were utilized with any binge drinking in the past year as the outcome variable and language spoken at home and time in USA as proxy measures of acculturation. Results. A total of 1,631 Asian-Americans (N = 665,195) were identified as binge drinkers. Binge drinking was positively associated with being first generation South Asian (OR = 3.05, 95% CI = 1.55, 5.98) and monolingual (English only) Vietnamese (OR = 3.00; 95% CI = 1.58, 5.70), especially among females. Other factors associated with increased binge drinking were being female (Chinese only), not being current married (South Asian only), and being an ever smoker (all subgroups except South Asians). Conclusion. First generation South Asians and linguistically acculturated Vietnamese, especially females, are at an increased risk of binge drinking. Future studies and preventive measures should address the cultural basis of such health risk behaviors among Asian-American adults.
