TOPLINE:
Women with steatotic liver disease (SLD) related to alcohol consumption are at greater risk of mortality than men with the same condition, new research suggested.
METHODOLOGY:
Researchers analyzed data from the US National Health and Nutrition Examination Survey III (NHANES III, 1988-1994), which included standardized ultrasonographic measures of hepatic steatosis, assessment of cardiometabolic risk traits, and questionnaire data on alcohol intake.Among 10,007 participants aged 20 years and older (mean age, 42 years; 50.3% men) who were included and followed for a median of 26.7 years, 1461 had metabolic dysfunction-associated steatotic liver disease (MASLD), 105 alcohol-related liver disease (ALD), 225 metabolic dysfunction-associated and alcohol-related liver disease (MetALD), 180 other types of SLD, and 8036 no SLD.Researchers examined SLD-associated risks for all-cause mortality after adjustment for baseline age, smoking status, systolic blood pressure, antihypertensives, type 2 diabetes, diabetic medication use, body mass index, total cholesterol, high-density lipoprotein cholesterol, lipid-lowering therapy, race, and family income.
TAKEAWAY:
In men, the prevalence of MASLD, MetALD, and ALD was 18.5%, 3.2%, and 1.7%, respectively, whereas the corresponding prevalence among women was 10.3%, 1.2%, and 0.3%, respectively.In multivariable-adjusted survival analyses, MASLD was not significantly associated with all-cause mortality for either sex compared with those without SLD.In contrast, MetALD was associated with an 83% higher hazard of all-cause mortality in women (hazard ratio [HR], 1.83), but not significantly associated with mortality in men.ALD was significantly associated with all-cause mortality in both sexes, with a greater magnitude in women than men (HRs, 3.49 vs 1.89, respectively) — the equivalent of about a 160% higher mortality risk for women.With regard to SLD severity, the trend across worsening phenotypes (ie, MASLD, MetALD, or ALD) was significant for sex differences in mortality but not in prevalence.
IN PRACTICE:
“Because alcohol consumption is modifiable, limiting alcohol intake particularly in women at risk for SLD could be critical as part of efforts to mitigate mortality risk in patients with SLD,” the authors wrote.
SOURCE:
The study, led by Hongwei Ji of Qingdao University, Qingdao, Shandong, China, and Susan Cheng, MD, Cedars-Sinai Medical Center, Los Angeles, California, was published in the February issue of the Journal of Hepatology.
LIMITATIONS:
The study data came from NHANES III, which was conducted between 1988 and 1994. This is a potential limitation, as the prevalence of metabolic dysfunction and alcohol use may have changed since then.
DISCLOSURES:
The study was funded in part by the National Natural Science Foundation of China, the Taishan Scholar Program of Shandong Province, the Shandong Provincial Natural Science Foundation, the National Institutes of Health, and the NIH National Center for Advancing Translational Sciences UCLA Clinical and Translational Research Center. The authors declared no relevant conflicts of interest.
