Longitudinal Associations of 12th-Grade Binge Drinking With Risky Driving and High-Risk Drinking

To study the longitudinal associations of 12th-grade binge drinking with driving while impaired (DWI), riding with an impaired driver (RWI), blackouts, extreme binge drinking, and risky driving (self-reported Checkpoints Risky Driving Scale) among emerging adults up to 4 years after leaving high school.

The data were all 7 waves (W 1 to W 7 of the NEXT Generation Health Study; a US nationally representative study (N = 2785) with a probability cohort of 10th-graders (mean age = 16.2 years; SE = 0.03) starting in the 2009-2010 year. Binary and ordinal logistic regressions were used for the analysis.

Binge drinking prevalence in W1 to W3 was 27.2%, 23.8%, and 26.8%, respectively. Twelfth-grade binge drinking was associated with a higher likelihood of DWI, RWI, blackouts, and risky driving in W4 to W7 and extreme binge drinking in W7. Adolescents who binged ≥3 times in high school were more likely to DWI, RWI, blackout (W4 to W7), be involved in extreme binge drinking (W7), and report riskier driving several years after high school. In some waves, parental practices appeared to have enduring effects in protecting against DWI, RWI, and blackouts.

Twelfth-grade binge drinking is a robust predictor of early adulthood DWI, RWI, blackout, extreme binge drinking, and risky driving. Our study suggests that ongoing parental practices could be protective against DWI, RWI, and blackouts once adolescents transition from high school into early adulthood. Prevention programs that incorporate binge drinking-focused screening and bolster parental practices may reduce the likelihood of later major alcohol-related health-risk behaviors and consequences in emerging adults.
