Impaired-Driving Prevalence Among US High School Students: Associations With Substance Use and Risky Driving Behaviors

摘要

Objectives. We examined the prevalence of impaired driving among US high school students and associations with substance use and risky driving behavior. Methods. We assessed driving while alcohol or drug impaired (DWI) and riding with alcohol- or drug-impaired drivers (RWI) in a nationally representative sample of 11th-grade US high school students (n?=?2431). We examined associations with drinking and binge drinking, illicit drug use, risky driving, and demographic factors using multivariate sequential logistic regression analysis. Results. Thirteen percent of 11th-grade students reported DWI at least 1 of the past 30 days, and 24% reported RWI at least once in the past year. Risky driving was positively associated with DWI (odds ratio [OR]?=?1.25; P
