Preventing Underage Drinking: Evidence-Based Strategies for Parents and Communities

Underage drinking causes 3,500+ deaths/year in US (NIAAA) and increases risk of injury, violence, sexual assault, academic failure, and adult alcohol use disorder.

Effective Prevention Layers

Level	Strategies
Family	Clear no-use rules, consistent consequences, monitoring, modeling moderate/no use, open communication, family meals
School	Evidence-based curricula (LifeSkills, Project ALERT), positive climate, extracurriculars, screening/brief intervention
Community	Enforcement of MLDA 21, compliance checks, social host laws, keg registration, restricting outlet density, advertising limits
Policy	Alcohol taxes, minimum pricing, limiting hours/days of sale, sobriety checkpoints, ignition interlocks

Parental Communication Tips

• Start early (age 9–11); use teachable moments.
• State clear expectations: “In our family, we don’t drink until 21.”
• Discuss real consequences (legal, academic, athletic, health).
• Role-play refusal skills.
• Know their friends, whereabouts, social media.

Warning Signs

• Mood changes, declining grades, new friends, secrecy, alcohol odor, missing money.

Community coalitions (CADCA model) reduce youth drinking 20–30% over 5 years.
