Different minimal alcohol consumption in male and female individuals with metabolic dysfunction‐associated fatty liver disease.

Background and Aims: The relationship between moderate alcohol intake and health outcomes among individuals with metabolic dysfunction‐associated fatty liver disease (MAFLD) is complex. Our aim was to investigate the association of minimal alcohol consumption with all‐cause and cause‐specific mortality among MAFLD individuals of different genders. Methods: Our study included 2630 MAFLD individuals from the Third National Health and Nutrition Examination Survey. Cox regression analysis was performed to assess the association between alcohol use measures and all‐cause and cause‐specific mortality. Restricted cubic spline curves were used to evaluate the relationship between alcohol consumption per week and all‐cause mortality. Results: In the entire MAFLD cohort, we observed significant disparities in clinical characteristics between male and female individuals with MAFLD. Higher weekly alcohol consumption was significantly associated with all‐cause and cause‐specific mortality (male, hazard ratios [HRs]: 1.009, 95% CIs: 1.004–1.014; female, HRs: 1.032, 95% CIs: 1.022–1.042). In males with MAFLD, a linear association with all‐cause mortality was observed for weekly alcohol consumption (p for non‐linearity =.21). Conversely, in females with MAFLD, the risk of all‐cause mortality remained relatively stable until 2 drinks per week, after which it rapidly increased with each additional drink consumed, and the increase in mortality risk was higher than that observed in males (p for non‐linearity <.05). Conclusions: Our findings indicate that any increase in weekly alcohol consumption was associated with increased all‐cause mortality in men with MAFLD. Conversely, consuming less than 2 drinks per week had minimal impact on the risk of mortality among female. [ABSTRACT FROM AUTHOR]
