ABSTRACT

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) and alcohol consumption have both increased in recent years, and there is debate as to whether nonheavy alcohol use is safe in MASLD. We analyzed the association between different nonheavy alcohol use patterns and at-risk liver fibrosis among individuals with MASLD.

METHODS: We conducted a cross-sectional study of 1072 eligible National Health and Nutrition Examination Survey participants with MASLD who reported nonheavy alcohol consumption. We used vibration-controlled transient elastography to define the primary outcome of at-risk liver fibrosis as >8.2 kPa (stage F2-F4). Multivariable logistic regression models were used to determine the association of different alcohol consumption patterns (average drinks/day, drinking days/week, weekly alcohol intake, type of alcoholic beverage) and at-risk hepatic fibrosis, controlling for demographic/socioeconomic, lifestyle/dietary, and metabolic risk factors.

RESULTS: Exclusive liquor or cocktail drinkers had a 5.02-fold odds of at-risk fibrosis (95% CI: 1.15-21.95) compared with non-drinkers when controlling for potential confounders. While consuming an average of 2 drinks/day, ≥3 drinking days/week, or 1-3 drinks/week appeared to have a lower association with at-risk fibrosis when controlling for demographic/socioeconomic risk factors, the association was not present after controlling for lifestyle/dietary and metabolic risk factors.

CONCLUSIONS: There is an association between exclusive liquor/cocktail consumption and at-risk liver fibrosis in patients with MASLD who report nonheavy alcohol consumption.
