title: A comparison of substance use and injury among Mexican American emergency room patients in the United States and Mexicans in Mexico.
abstract: BACKGROUND
  Emergency room (ER) studies have found differences in the association of alcohol with injury (intentional and unintentional) across cultures. These differences may be due to differences in drinking patterns across cultures. Few comparative data have been reported on associations of alcohol and injury between Mexican American ER patients and ER patients living in Mexico, and general population studies suggest that Mexican Americans may adopt more frequent heavy drinking patterns after migrating to the United States.
  
  
  METHODS
  A comparative analysis of drinking, drug use, and injury was performed in probability samples of 550 ER patients from Santa Clara County (San Jose, CA) and 1417 ER patients in Pachuca (Hidalgo), Mexico.
  
  
  RESULTS
  Both injured and uninjured (i.e., medical conditions) patients in Pachuca were less likely to report heavy drinking, drug use, drunkenness, or alcohol-related problems compared with those in Santa Clara. Those scoring high on level of acculturation in Santa Clara were more likely to report both drinking and drug use before the event, and heavy drinking, drug use, and consequences related to drinking in the last year compared with those scoring lower. Those scoring low on acculturation were similar on substance use variables to those in the Pachuca sample.
  
  
  CONCLUSIONS
  Findings suggest that alcohol's association with injury may not just reflect typical drinking patterns in a culture. Among Mexican Americans, this association my vary by acculturation, and those migrating to the United States may be at increased risk for alcohol-related injury as their drinking patterns undergo change to those of the dominant culture. The ER, in this context, may take on increasing importance as a site for health services providers to implement intervention and prevention services for alcohol-related consequences in this ethnic group.
