Abstract
BACKGROUND: Skeletal muscle as an essential body composition component plays an important role in maintenance of normal growth and development as well as systemic glucose metabolism in children. No nationwide reference data for skeletal muscle mass for Chinese youths are available in China. We aimed to establish the sex-specific and age-specific percentile reference values of skeletal muscle mass for Chinese children and adolescents. METHODS: This study consisted of 10 818 children and adolescents aged 3-17 years in Chinese urban area during 2013-15. Dual-energy X-ray absorptiometry scan was performed to measure whole body muscle mass and appendicular skeletal muscle mass. Lambda-mu-sigma method was used to obtain the sex-specific and age-specific percentile curves of muscle mass indices. RESULTS: Overall, whole body muscle mass and appendicular skeletal muscle mass indices showed an increasing trend with age for both sexes, with boys vs. girls having higher values of all muscle mass indices. Whole body muscle mass index in boys increased slightly before age 9 years and then increased rapidly until 15 years and slowed down thereafter, while the mean values in girls increased slightly before age 8 years, increased rapidly until 14 years and remained stable thereafter. Appendicular skeletal muscle mass index increased rapidly until age 16 years and then increased slightly for boys; by contrast, for girls, the mean values increased consistently before age 14 years but showed a slightly decreasing trend after that. CONCLUSIONS: This study established sex-specific and age-specific percentile reference values for skeletal muscle mass for Chinese children and adolescents aged 3-17 years. These reference values can be used to evaluate the muscular development in Chinese children and adolescents.

Skeletal muscle cells are highly abundant and metabolically active and are known to ‘communicate’ their energy demands to other organs through active secretion. Muscle-derived secretory proteins include a variety of cytokines and peptides collectively referred to as ‘myokines’ that exert autocrine, paracrine or endocrine effects. Analyses of the skeletal muscle secretome revealed that numerous myokines are secreted in response to contraction or strength training, and that these factors not only ...

Objectives No nationwide paediatric reference standards for bone mineral density (BMD) are available in China. We aimed to provide sex-specific BMD reference values for Chinese children and adolescents (3–18 years). Methods Data (10 818 participants aged 3–18 years) were obtained from cross-sectional surveys of the China Child and Adolescent Cardiovascular Health in 2015, which included four municipality cities and three provinces. BMD was measured using Hologic Discovery Dual Energy X-ray Absor...

Background Skeletal muscle mass (SMM) plays a crucial role in systemic glucose metabolism. Objective To obtain reference data on absolute and relative values of SMM for Korean children and adolescents. Methods Cross-sectional results from 1919 children and adolescents (1024 boys) aged 10–18 years that underwent dual-energy X-ray absorptiometry (DXA) during the Korean National Health and Nutrition Examination Survey 2009–2011 were analyzed. SMMs were evaluated as follows; absolute SMM (appendicul...

SummaryWhat is already known about this subject Skeletal muscle is considered a major site of insulin-mediated glucose disposal and is thus a key tissue in whole-body glucose homeostasis. Low muscle mass and fitness is associated with metabolic risk and muscular strength is positively related to higher insulin sensitivity in children and adolescents. The use of skeletal muscle mass measurement in surveillance has been constrained by the absence of normative data that identifies individuals acros...

Purpose In youth, poor cardiorespiratory and muscular strength are associated with elevated metabolic risk factors. However, studies examining associations between strength and risk factors have been done exclusively in high income countries, and largely in Caucasian cohorts. The aim of this study was to assess these interactions in schoolchildren in Colombia, a middle income Latin American country. Methods We measured body mass index, body composition, handgrip strength (HG), cardiorespiratory ...

Summary Sarcopenia may be diagnosed in the clinic using operational definitions based on low muscle mass or function. This prospective, population-based study revealed that sex-specific associations may exist between operational definitions of sarcopenia and falls in community-dwelling middle-aged and older adults.

Epidemiological studies in humans suggest that skeletal muscle aging is a risk factor for the development of several age-related diseases such as metabolic syndrome, cancer, Alzheimer’s disease, and Parkinson’s disease. Here we review recent studies in mammals and Drosophila highlighting how nutrient- and stress-sensing in skeletal muscle can influence lifespan and overall aging of the organism. In addition to exercise and indirect effects of muscle metabolism, growing evidence suggests that mus...

Summary Currently used diagnostic measures for sarcopenia utilize different measures of muscle mass, muscle strength, and physical performance. These diagnostic measures associate differently to bone mineral density (BMD), as an example of muscle-related clinical outcome. These differences should be taken into account when studying sarcopenia.

Summary The aim of this study was to determine the relationship between reduced muscle mass (sarcopenia) and areal bone mineral density (BMDa) in middle-aged and elderly community-dwelling European men. Men with sarcopenia had significantly lower BMDa and were more likely to have osteoporosis compared with men without sarcopenia.

BACKGROUND: The pediatric relative fat mass (RFM) has been recently presented and validated as an index for estimating percentage body fat (%BF) in North American children and adolescents. Similar to body mass index (BMI) and tri-ponderal mass index (TMI), RFM uses anthropometric measures (i.e., weight, height and waist circumference) to estimate body composition. The primary purpose of this study was to validate the newly developed RFM equation for %BF prediction in Southern Brazilian adolescen...

BACKGROUND: Malnutrition is a common complication in children with chronic diseases. Sarcopenia is one component of malnutrition, characterized by reduced skeletal muscle mass (SMM) and muscle function. The presence of sarcopenia is associated with adverse outcomes in children. Although there is growing research interest in sarcopenia, no review has been done on this novel concept in pediatrics. The purpose of this review was to explore current evidence in sarcopenia with and without obesity and...

The body composition phenotype of low lean mass (LM) has been associated with metabolic disorders and impaired physical functioning in the pediatric population. Abnormalities in body composition may be identified using reference curves; however, no reference data on LM is available for Brazilian adolescents. The purpose of this study was to present reference data, including percentile curves, of whole body LM, lean mass index (LMI), appendicular lean mass (ALM), and fat mass for Southern Brazili...

Objectives: The goal of this study was to develop regression equations to estimate LM with anthropometric variables and to propose percentiles for evaluating by age and sex. Methods: A cross sectional study was conducted with 2,182 Chilean students (1,347 males and 835 females). Ages ranged from 5.0 to 17.9 years old. A total body scan was carried out with the double energy X-ray anthropometry (DXA) to examine and measure lean muscle mass of the entire body. Weight, height, and the circumference...
