Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common, often overlooked liver condition. Its impact on quality-of-life in older adults is not well understood. We examined the association between MASLD and physical and mental quality of life in a well-characterized cohort of Australians aged 70 and older. MASLD was identified using Fatty Liver Index ≥ 60 and consensus lifestyle and cardiometabolic criteria and assessed at baseline and at 3 years. PCS and MCS scores were measured annually using the 12-Item Short Form Health Survey. Generalized estimating equations adjusted for key confounders were used to evaluate the association of baseline and time-updated MASLD with longitudinal HRQoL outcomes. Analysis of 8880 participants (median follow-up 5.5 years) showed that baseline MASLD was associated with lower, then declining PCS over follow-up compared with no MASLD (mean difference -1.3; 95% CI -1.8, -0.9). Exploratory analysis showed stronger associations among women and individuals with frailty. Findings were similar when time-updated MASLD was modelled. While the presence of MASLD was associated with a deterioration in PCS, the difference was below the minimal clinically important difference (MCDI) of 4.2, indicating limited clinical implications at the individual level. For MCS, associations with MASLD were inconsistent and did not show a clear linear pattern, whereas MASLD was associated with lower mental HRQoL. Although the differences in PCS and MCS were small and below the MCID, these findings, at the population level, support integrating metabolic liver risk assessment with geriatric and psychiatric care, including screening for frailty, functional limitations, and depression.

Longitudinal studies have shown an association between diet quality and depression. However, reverse causality, unmeasured confounding, and selection bias remained important limitations. We aim to examine the relationship between diet quality and depression in older adults while addressing these issues and explore modification role of genetic predisposition to depression and low-grade inflammation. We emulated a target trial of dietary interventions using data from the ASPREE cohort. An ultra-processed food (UPF) index and an anti-inflammatory diet measure were extracted from a food frequency questionnaire to quantify diet quality. Depressive symptoms were assessed annually with a Center for Epidemiologic Studies-Depression 10-item score of ≥8. A polygenic score was derived using the latest Psychiatric Genomics Consortium data for major depression. Systemic inflammation was assessed using circulating high-sensitivity C-reactive protein. Inverse probability treatment weighting was applied to balance measured confounders. The effects of diet quality on depressive symptoms were estimated using generalised estimating equations. A total of 7220 participants (52.7% female), aged 70+ years, were followed for a median of 5.7 years. High UPF consumption was associated with a higher risk of depressive symptoms (RR: 1.12, 95% CI: 1.03-1.21), while an anti-inflammatory diet was associated with lower depressive symptoms (RR: 0.93, 95% CI: 0.86-1.00). Genetic predisposition or low-grade inflammation did not modify the observed associations. Higher diet quality is associated with a lower risk of depressive symptoms, independent of genetic predisposition or low-grade inflammation, which may support dietary interventions as a modifiable lifestyle strategy for mental health promotion and prevention in older adults.
