The effect of cross-border mobility on alcohol and drug use among Mexican-American residents living at the US-Mexico border

摘要

Introduction: Little epidemiological evidence exists on alcohol or other substance use and related problems along the U.S.-Mexico border, although the border has been the focus of recent media attention related to the escalating drug/violence "epidemic". The purpose of this study was to analyze the association of variables related to crossing the border (cross-border mobility) with three substance use outcomes reported for the last year: 1) heavy drinking (5 + drinks per day for men or 4 + for women), 2) alcohol use disorder (ADD), and 3) co-occurring heavy drinking and drug use (any use of illicit and/or non-medically prescribed drugs).
