Abstract

Background: Advanced glycation end products (AGEs) are accumulated with aging in various tissues of humans. The soluble receptor for AGEs (sRAGE) exerts a protective role against the development of aging-related chronic disorders by neutralizing the action of AGEs. We investigated the implication of sRAGE on low muscle mass in Asian men and women. Methods: This cross-sectional study included a 390-participant, nondiabetic subcohort recruited within the framework of the Korean Sarcopenic Obesity Study, an ongoing prospective cohort study. Low muscle mass was defined based on the distribution of appendicular skeletal muscle mass divided by body mass index, as proposed by the Foundation for the National Institutes Sarcopenia Project. Results: Serum sRAGE levels were significantly lower in participants with low muscle mass than in participants without low muscle mass (0.76 [0.60-1.00] ng/mL vs 0.87 [0.67-1.15] ng/mL, P =.005). In age- and sex-adjusted correlation analyses, appendicular skeletal muscle mass divided by body mass index was associated with sRAGE (r = 0.109, P =.037). Furthermore, decreased circulating levels of sRAGE are independently associated with low muscle mass (odds ratio = 0.254, P =.002) after adjusting for confounding factors, including insulin resistance and inflammatory markers. Conclusions: The present study shows that a low circulating level of sRAGE may be an independent risk factor for the presence of low muscle mass.

Funding Information:
The Korean Sarcopenic Obesity Study (KSOS), which was supported by the Korea Science and Engineering Foundation, was a longitudinal, observational study of 1027 well‐functioning men and women recruited in 2007‐2009. This prospective observational cohort study was designed to examine the prevalence of sarcopenia in Korean adults and to evaluate its effects on metabolic disorders and health outcomes.15-17 The KSOS study is composed of nondiabetic and diabetic subcohorts and a young reference group. The present study recruited eligible participants over 40 years of age with no history of any type of diabetes, cardiovascular disease (myocardial infarction, unstable angina, stroke, or cardiovascular revascularization), stage 2 hypertension (resting blood pressure, ≥160/100 mm Hg), malignant disease, or severe renal or hepatic disease. Among 442 participants in the nondiabetic subcohort with complete demographic data, we excluded participants without complete clinical laboratory measures or body composition measures. Ultimately, 390 participants (153 men and 237 women) with complete clinical laboratory data and body composition data were included for this study. Participants who exercised regularly at a moderate intensity were asked about the frequency with which they exercised per week, and the length of time per exercise session. Regular exercise was defined as exercising 5 or more times per week.17 Smoking status was divided into 3 categories: current smoker, ex‐smoker, and nonsmoker. All participants provided written informed consent, and the Korea University Institutional Review Board, in accordance with the Declaration of Helsinki of the World Medical Association, approved the study protocol.
