High-intensity drinking by underage young adults in the United States.

ABSTRACT: AIMS:To estimate (1) the prevalence of underage binge drinking, high-intensity drinking and intoxication among young adults aged 19/20 years; (2) change in these behaviors across the transition out of high school and across historical time; and (3) associations between these behaviors and key covariates, including college status. DESIGN, SETTING, PARTICIPANTS:Longitudinal data from the US nationally representative Monitoring the Future study included 1657 respondents first surveyed as 12th graders (modal age 18 years) in 2005-13 and again at modal age 19/20 years in 2006-14. MEASUREMENTS:Self-reported measures of alcohol use, demographics, college attendance and living situation. FINDINGS:Binge drinking (5+ drinks on one occasion) was reported by 24.2% [95% confidence interval (CI) = 22.0, 26.5] of young adults aged 19/20; 10.3% (CI = 8.7, 11.9) reported high-intensity drinking of 10+ drinks; 4.2% (CI = 3.1, 5.2) reported 15+ drinks. Usual moderate/high intoxication when drinking was reported by 33.1% (CI = 30.6, 35.6); 29.6% (CI = 27.2, 32.0) reported usual sustained intoxication of 3+ hours. Significant variability (P < 0.001) in these behaviors from ages 18 to 19/20 was observed. Significant decreases (P < 0.05) across historical time in 5+ and 10+ drinking were found. Four-year college students not residing with parents had significantly higher odds of moderate/high intoxication, binge drinking and high-intensity drinking compared with other groups (P < 0.001). CONCLUSIONS:Young adult underage binge drinking (5+ drinks on one occasion), high-intensity drinking (10+ and 15+ drinks) and intoxication are relatively common in the United States, and show meaningful variability across the transition out of high school. Four-year college students and those who do not live with their parents are more likely to engage in high-intensity drinking than their peers.

Project description:Heavy episodic alcohol consumption (also termed binge drinking) contributes to a wide range of health and cognitive deficits, but the associated brain-based indices are poorly understood. The current study used electroencephalography (EEG) to examine spontaneous neural oscillations in young adults as a function of quantity, frequency, and the pattern of their alcohol consumption. Sixty-one young adults (23.4 ± 3.4 years of age) were assigned to binge drinking (BD) and light drinking (LD) groups that were equated on gender, race/ethnic identity, age, educational background, and family history of alcoholism. EEG activity was recorded during eyes-open and eyes-closed resting conditions. Each participant's alpha peak frequency (APF) was used to calculate absolute power in individualized theta and alpha frequency bands, with a canonical frequency range used for beta. APF was slower by 0.7 Hz in BD, especially in individuals engaging in high-intensity drinking, but there were no changes in alpha power. BD also exhibited higher frontal theta and beta power than LD. Alpha slowing and increased theta power in BD remained after accounting for depression, anxiety, and personality characteristics, while elevated beta power covaried with sensation seeking. Furthermore, APF slowing and theta power correlated with various measures of alcohol consumption, including binge episodes and blackouts, but not with measures of working and episodic memory, cognitive flexibility, processing speed, or personality variables, suggesting that these physiological changes may be modulated by high-intensity alcohol intake. These results are consistent with studies of alcohol-use disorder (AUD) and support the hypothesis that binge drinking is a transitional stage toward alcohol dependence. The observed thalamocortical dysrhythmia may be indicative of an excitatory-inhibitory imbalance in BD and may potentially serve as an index of the progressive development of AUD, with a goal of informing possible interventions to minimize alcohol's deleterious effects on the brain.
