ABSTRACT
BACKGROUND: The coexistence of sarcopenia and obesity has been established as a pivotal factor driving the pathological progression of metabolic dysfunction-associated steatotic liver disease (MASLD). This study systematically evaluates the prevalence and risk of MASLD in patients with sarcopenic obesity (SO).
METHOD: A comprehensive literature search was conducted in PubMed, Cochrane Library, EMBASE, Web of Science and SCOPUS up to March 2025. All studies investigating the association between SO and MASLD were included in this meta-analysis. Two independent reviewers performed screening and data extraction. ORs and 95% CIs were calculated using random effect models. Subgroup analysis was used to identify the sources of heterogeneity. Heterogeneity was assessed using Cochran’s Q test and quantified via the I² statistic. Quality assessment and publication bias (by Funnel plots and Egger’s test) evaluation were also performed.
RESULTS: Thirteen studies involving 35,373 SO patients (from six countries) were included after screening. Odds ratios (ORs) of the included studies were combined by random effect model. The pooled results revealed that 63.4% of SO patients had MASLD. Compared to non-SO individuals, SO was significantly associated with an increased risk of MASLD (OR = 4.45, 95% confidence interval (CI): 2.57-7.72, P < 0.001). Females exhibited a higher MASLD risk than males (OR = 4.22, 95% CI: 2.10-8.50 vs. OR = 7.56, 95% CI: 2.39-23.92). Substantial heterogeneity was observed across pooled results and subgroups. Additionally, SO patients had a 2.34-fold higher risk of MASLD-related fibrosis than non-SO individuals (OR = 2.34, 95% CI: 1.78-3.08, P < 0.001).
CONCLUSION: SO may be closely associated with a high prevalence of MASLD and accelerated fibrosis progression. These findings highlight SO as a potential high-risk population for MASLD, underscoring the need for targeted screening and intervention strategies. However, more high-quality research with unified definitions and different races is needed.
