Appendicular skeletal muscle mass is associated with metabolic dysfunction-associated steatotic liver disease severity in young men: a cross-sectional and longitudinal study. Hepatol Int 2025; 19:181-190. [PMID: 39394385 DOI: 10.1007/s12072-024-10737-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2024] [Accepted: 09/28/2024] [Indexed: 10/13/2024]
Abstract
BACKGROUND AND AIM Although appendicular skeletal muscle mass (ASM) has been linked to the severity of hepatic steatosis, investigations of its correlation among younger age groups are lacking. We aimed to elucidate the role of ASM in determining the severity of metabolic dysfunction-associated steatotic liver disease (MASLD) in younger patients. METHODS Retrospective data were collected from patients younger than 35 years who visited the Armed Forces Goyang Hospital between June 2022 and February 2024. Steatosis presence was determined by a controlled attenuation parameter score ≥ 250 dB/m, and significant fibrosis was identified with liver stiffness measurement > 8.0 kPa. ASM was measured using multifrequency bioelectrical impedance analysis (InBody 620). RESULTS Of 910 participants, 630 were diagnosed with MASLD. Patients with MASLD had lower ASM/fat mass (ASM/F) (1.02 vs. 1.91; p < 0.001), ASM/body mass index (BMI) (0.91 vs. 1.04/m2; p < 0.001), and ASM/body weight (ASM/W) (29.5% vs. 33.8%; p < 0.001) than non-MASLD patients. Additionally, ASM/F, ASM/BMI, and ASM/W significantly decreased with worsening steatosis severity and were notably lower in patients with significant fibrosis. Among 107 patients with MASLD who underwent two examinations with a median interval of 6.0 months, those with increased ASM/F showed a higher proportion of steatosis regression and a lower proportion of steatosis worsening than those with decreased ASM/F (steatosis regression, 43.1% vs. 22.9%; worsening, 11.1% vs. 28.6%; p = 0.031). All three ASM indices were significant factors in steatosis regression during the study period. CONCLUSIONS ASM is associated with the severity of steatosis and significant fibrosis in MASLD in young adults < 35 years.

Association of muscle mass, grip strength and fat-to-muscle ratio and metabolic dysfunction-associated steatotic liver disease in a middle-to-elderly aged population. Ann Med 2024; 56:2390169. [PMID: 39129458 PMCID: PMC11321103 DOI: 10.1080/07853890.2024.2390169] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 06/05/2024] [Accepted: 06/26/2024] [Indexed: 08/13/2024] Open
Abstract
OBJECTIVE The association of appendicular skeletal muscle mass (ASM), grip strength and fat-to-muscle ratio (FMR) and the progression of metabolic dysfunction-associated steatotic liver disease (MASLD) are not well known. MATERIALS AND METHODS This study included participants older than 40 years who underwent bioelectrical impedance assessment in Prevalence of Metabolic Diseases and Risk Factors in Shunde (SPEED-Shunde). We measured grip strength with an electronic grip strength metre. ASM and grip strength were adjusted by dividing body mass index (BMI). FMR was calculated as total fat mass to total muscle mass. Liver steatosis and liver fibrosis were evaluated by vibration-controlled transient elastography. Multifactorial logistic regression was used to analyse the relationship between ASM, grip strength, FMR, and MASLD or MASLD-associated liver fibrosis. We performed subgroup analyses according to sex, age and BMI. Interaction tests and linear trend tests were also conducted. RESULTS This study included a total of 3277 participants. FMR was positively associated with MASLD (OR: 1.89, 95% CI: 1.66-2.15) and MASLD-associated liver fibrosis (OR: 1.70, 95% CI: 1.22-2.37). While ASM/BMI (OR: 0.59, 95% CI: 0.52-0.67) or grip strength/BMI (OR: 0.72, 95% CI: 0.66-0.78) were negatively associated with MASLD. Interactions were observed between ASM/BMI and age, grip strength and sex in MASLD, as well as FMR and MASLD-associated liver fibrosis. CONCLUSION In a middle-to-elderly aged population, FMR was positively associated with the risk of MASLD and MASLD-associated liver fibrosis, and muscle mass and grip strength were negatively associated with MASLD, rather than MASLD-associated liver fibrosis.

Han CI, Lee J. Impact of Overseas Deployment on Fatty Liver and Metabolic Diseases Among Korean Soldiers. Mil Med 2024; 189:e1621-e1628. [PMID: 38330091 DOI: 10.1093/milmed/usae016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 11/27/2023] [Accepted: 01/15/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND The prevalence of metabolic diseases is increasing worldwide and is influenced by multiple environmental, psychological, and dietary factors. As overseas deployment (OD) of Korean soldiers brings about changes in these factors, this study aimed to explore the impact of OD on metabolic diseases. MATERIALS AND METHODS We collected paired health checkup data of Korean soldiers between January 2020 and December 2022, before and after their deployment. We analyzed changes in lipid profile, fasting glucose, and liver function biomarkers during OD and compared the prevalence of metabolic diseases before and after the OD. RESULTS A total of 2,953 soldiers were enrolled. During OD, body weight, body mass index, total cholesterol, low-density lipoprotein, and fasting glucose levels decreased significantly. Furthermore, the prevalence of obesity, impaired fasting glucose, and nonalcoholic fatty liver disease decreased significantly from 45.78% to 33.49%, P < .001; 38.60% to 34.41%, P < .001; and 24.89% to 18.88%, P < .001, respectively. In a subgroup analysis of participants with long-term deployment (duration >365 days), only the prevalence of obesity decreased significantly during deployment, whereas the prevalence of hypertension and dyslipidemia increased. CONCLUSIONS Metabolic biomarkers improved, and the prevalence of metabolic diseases decreased significantly during OD. However, personnel with long-term deployment did not experience significant improvements in these parameters. Further analysis is needed to identify the factors influencing these discrepancies.
