However, steatosis, cardiometabolic comorbidities and alcohol consumption are known to change over time. We investigated the association of the dynamic classification of SLD subtypes and all\u2010cause mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analysed data from the Canadian Longitudinal Study on Aging, a cohort of adults aged 45\u201385\u2009years that is followed every 3\u2009years or until death. Hepatic steatosis was identified using the NAFLD Ridge Score, and alcohol consumption was used to classify MASLD, MetALD and ALD. Marginal structural Cox proportional hazards models estimated associations between time\u2010varying SLD subtypes and mortality. Models were adjusted for socio\u2010demographic, lifestyle and cardiometabolic factors, and stratified by sex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 16\u2009560 participants (52.1% female; median age 58 [IQR 51\u201366] years), 1041 deaths occurred within a median of 7.8\u2009years. Within the first 3\u2009years, 35.4%, 23.7% and 22.6% of participants with ALD, MetALD and MASLD, respectively, transitioned to different SLD subtypes. Mortality risk increased with increasing levels of alcohol among people with and without steatosis, and ALD demonstrated the highest mortality risk (aHR 6.11; 95% CI 1.76\u201321.19). Sex\u2010stratified analyses suggested higher mortality among females, with the highest mortality rate in females with ALD compared to males (11.37 vs. 5.60 per 1000 person\u2010years).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SLD phenotypes are dynamic, with substantial transitions between disease subtypes over time.
