Obese Youth

Previous studies in adults have found a correlation between nonalcoholic fatty liver disease (NAFLD) and sarcopenia. The present study evaluated the relationship between NFALD and skeletal muscle mass in overweight/obese youth. A total of 234 children and adolescents (age 8-16) was stratified into tertiles based on relative muscle mass (RMM). Total, regional lean body mass, and total fat mass were obtained by dual-energy X-ray absorptiometry. RMM was defined as the percent of muscle mass (kg) relative to the sum of muscle and fat mass (kg). NAFLD was diagnosed via ultrasononography and a subset of participants with NAFLD (n=40) underwent a liver biopsy. The lowest tertile had a significantly higher risk for obesity, dyslipidemia, insulin resistance, metabolic syndrome, NAFLD, and nonalcoholic steatohepatitis (NASH). The present study demonstrated an association between low muscle mass, NAFLD, and NASH in overweight/obese youth. Despite the strong scientific merits of the present study, a lack of race/ethnic description could be a major critique as different ethnic background (specifically in the minorities) may be disproportionately impacted by fat distribution and relative muscle mass. Even though there is a clear relationship between sarcopenia and NAFLD in the elderly, this association may not stem from the same origin in the pediatric population. Lastly, but not least, future studies should evaluate NAFLD in obese youth with varying degrees of metabolic disorders (i.e., metabolic syndrome).

Clinical Records

A relationship between nonalcoholic fatty liver disease (NAFLD) and sarcopenia has been suggested. The aim of this study was to evaluate the association between NAFLD and skeletal muscle mass measured by computed tomography (CT). The clinical records of individuals visiting our center for a routine health check-up who underwent abdominal ultrasonography and abdominal CT scanning were retrospectively reviewed. Sarcopenia was diagnosed according to body mass index (BMI)-adjusted skeletal muscle mass, which was measured by CT (CT-measured skeletal muscle index (SMICT)). Of the 1828 subjects (1121 males; mean age 54.9 ± 9.5 years), 487 (26.6%) were obese (BMI ≥ 25 kg/m2), and 454 (24.8%) had low muscle mass. Sarcopenic subjects had a significantly higher prevalence of NAFLD than nonsarcopenic subjects, regardless of obesity (35.9% vs. 26.8%, p = 0.004 in the nonobese group; 76.6% vs. 63.0%, p = 0.003 in the obese group). Sarcopenia was significantly associated with the risk of NAFLD (adjusted odds ratio (OR) (95% confidence interval (CI)), 1.51 (1.15–1.99)), and the risk of NAFLD increased with increasing severity of sarcopenia (adjusted OR (95% CI), 1.45 (1.09–1.92) vs. 2.51 (1.16–5.56), mild vs. severe sarcopenia, respectively). When the risk of NAFLD was analyzed according to the SMICT quartiles, the adjusted OR and 95% CI for the lowest muscle mass quartile compared to the highest were 1.78 (1.17–2.72) in males and 2.39 (1.13–5.37) in females. Low skeletal muscle mass, which was precisely measured by CT, is independently associated with NAFLD, suggesting that sarcopenia is a risk factor for NAFLD.

Although sarcopenia is known to be a risk factor for non-alcoholic fatty liver disease (NAFLD), whether NAFLD is a risk factor for the development of sarcopenia is not clear. We investigated relationships between NAFLD and low skeletal muscle mass index (LSMI) using three different datasets. Participants were classified into LSMI and normal groups. LSMI was defined as a body mass index (BMI)-adjusted appendicular skeletal muscle mass <0.789 in men and <0.512 in women or as the sex-specific lowest quintile of BMI-adjusted total skeletal muscle mass. NAFLD was determined according to NAFLD liver fat score or abdominal ultrasonography. The NAFLD groups showed a higher hazard ratios (HRs) with 95% confidence intervals (CIs) for LSMI than the normal groups (HRs = 1.21, 95% CIs = 1.05–1.40). The LSMI groups also showed a higher HRs with 95% CIs for NAFLD than normal groups (HRs = 1.56, 95% CIs = 1.38–1.78). Participants with NAFLD had consistently less skeletal muscle mass over 12 years of follow-up. In conclusion, LSMI and NAFLD showed a relationship. Maintaining muscle mass should be emphasized in the management of NAFLD.
