“…Aims were tested using time-varying effect modeling (TVEM; Lanza et al, 2014; Tan et al, 2012), a flexible approach that permits examinations of how variables and associations between variables change over continuous time or age. TVEM can highlight ages at which high-intensity drinking is most prevalent and when it is most associated with AUD, relative to HED-only drinking.…”

Background Heavy episodic drinking (HED) or consuming 4+/5+ drinks in one 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 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 alcohol use disorder for HED-only drinkers and high-intensity drinkers, and relative odds of experiencing an alcohol use disorder for high-intensity drinkers as compared to HED-only drinkers. Methods Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). The final analytic sample consisted of past-year drinkers aged 18 to 64 years (n=22,776). Results Time-varying effect modeling (TVEM) 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 three or more times greater odds of meeting criteria for an alcohol use disorder 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. Conclusions Future research aiming to identify drinkers most at risk for harms and in need of treatment may benefit from assessing the extent to which an individual exceeds the 8+/10+ threshold of drinking.
