Smoking Is Associated with Increased Risk of Binge Drinking in a Young Adult Hispanic Population at the US-Mexico Border.

Background: This study examines factors related to general health and health behavior, including smoking, that may be associated with binge drinking, drinking "at risk," and potential for alcohol use disorder among young adults of Mexican ancestry.

Methods: A total of 2191 young adult emergency department (ED) patients (18-30 years) of Mexican ancestry in a public hospital proximate to the US-Mexico border completed health surveys while they were waiting to be treated, including questions on general health, drinking, smoking, and drug use.

Results: Thirty-seven percent of the study participants reported binge drinking, 38% were "at-risk" alcohol users (above National Institute on Alcohol Abuse and Alcoholism guidelines), and 22% were Rapid Alcohol Problem Screen (RAPS) positive (indicating potential for alcohol use disorder).
