Heavy episodic drinking (HED) or consuming 4+/5+ drinks in 1 occasion for women/men is linked consistently with alcohol-related harms. Recent research suggests that many individuals drink at levels more than twice this cutoff (8+/10+ drinks), commonly referred to as "high-intensity drinking." Prevalence rates of high-intensity drinking and its dynamic association with alcohol use disorder (AUD) across all ages, however, remain unknown. The current study used data from a nationally representative sample to document age-varying prevalence rates of HED-only drinking and high-intensity drinking, prevalence rates of AUD for HED-only drinkers and high-intensity drinkers, and relative odds of experiencing an AUD for high-intensity drinkers as compared to HED-only drinkers.
Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III. The final analytic sample consisted of past-year drinkers aged 18 to 64 years (n = 22,776).
Time-varying effect modeling revealed that high-intensity drinking and HED-only drinking were equally prevalent during young adulthood and prevalence rates of both types of drinking generally became less common with increasing age. At all ages, high-intensity drinkers were at 3 or more times greater odds of meeting criteria for an AUD than HED-only drinkers. The association between high-intensity relative to HED-only drinking was strongest earlier in adulthood with approximately 83% of 18-year-old high-intensity drinkers having AUD relative to 42% of HED-only drinkers.
Future research aiming to identify drinkers most at risk of harms and in need of treatment may benefit from assessing the extent to which an individual exceeds the 8+/10+ threshold of drinking.
重度间断性饮酒（HED）或女性/男性一次性饮用 4+/5+杯酒与酒精相关危害密切相关。最近的研究表明，许多人饮酒量超过这一标准（8+/10+杯）的两倍以上，通常被称为“高强度饮酒”。然而，目前尚不清楚各年龄段高强度饮酒的流行率及其与酒精使用障碍（AUD）的动态关联。本研究使用来自全国代表性样本的数据，记录了仅 HED 饮酒和高强度饮酒的年龄变化流行率、仅 HED 饮酒者和高强度饮酒者的 AUD 流行率，以及高强度饮酒者与仅 HED 饮酒者相比发生 AUD 的相对几率。
数据来自国家酒精相关状况流行病学调查-III。最终分析样本包括过去一年饮酒且年龄在 18 至 64 岁的人群（n=22776）。
时变效应模型显示，在青年时期，高强度饮酒和仅 HED 饮酒同样普遍，随着年龄的增长，这两种类型的饮酒流行率普遍降低。在所有年龄段，高强度饮酒者发生 AUD 的几率是仅 HED 饮酒者的 3 倍或以上。与仅 HED 饮酒相比，高强度饮酒与 AUD 的关联在成年早期最强，大约 83%的 18 岁高强度饮酒者患有 AUD，而仅 HED 饮酒者的比例为 42%。
未来旨在确定最易受伤害和需要治疗的饮酒者的研究可能受益于评估个体超过 8+/10+饮酒量标准的程度。
