Binge drinking among US adolescents has been declining in recent years; an analysis of 8^th, 10^th, and 12^th grade students found the decline is partially related to birth cohorts, with reductions being the greatest in teens born from 1985 to 1990. Additional findings include:

• Slower reductions were observed among African American teens since 2007, when compared to whites.
• The gap among teens in varying socioeconomic groups is growing.
• The difference between males and females, on the other hand, is narrowing.
• Binge drinking was defined as consuming ≥5 alcoholic drinks in a row on 2 or more occasions during the previous 2 weeks.
