Body composition changes were related to nutrient intakes in elderly men but elderly women had a higher prevalence of sarcopenic obesity in a population of Korean adults

Prevalence of Sarcopenic Obesity in Adults with Class II/III Obesity Using Different Diagnostic Criteria

“…Considering measures of ASM with weight [31, 32], BMI [8], FMI [18], or FM [29, 33], our prevalence of sarcopenia ranged from 12.6 to 84.5% for females and 17.6 to 100% for males. Likewise, in the Newman et al [29] study, higher prevalence rates were observed for both sexes using a method in which ASM was considered in relation to height and FM compared to none using nonadjusted ASMI cut points.…”

“…b Where applicable, equivalent cut points derived from the study-specific cohort are listed in the text. c Cut points determined from reported sex-specific mean and standard deviation in Oh et al, 2015[32]. d HA-LM: high adiposity (FMI 50–100) and low muscle mass (ASMI 0–49.99) with individual z -scores based upon age, sex, and BMI.…”

Chapter 1 Definitions and diagnosis of sarcopenia

“…In addition, the prevalence (odds ratio) of metabolic syndrome was 1.98‐fold higher in the S and non‐O group, 7.53‐fold higher in the non‐S and O group, and 11.59‐fold higher in the S and O group compared with the non‐S and non‐O group . The S and O group had a larger number of women, and participants in this group also showed high fasting blood glucose and homeostatic model assessment for insulin resistance values . The participants in the S and O group showed lower bone density, balancing ability, parathyroid hormone levels and serum vitamin D concentrations, and the hazard ratio for mortality as a result of respiratory or gastrointestinal solid cancers was 4.2‐fold higher than the non‐S and O group .…”

“…With respect to measurement methods, of 13 papers regarding sarcopenic obesity, seven studies used DXA, two studies used bioelectrical impedance analysis, one study used computed tomography, one study used magnetic resonance imaging and two studies used calculation formulas a majority of papers used the DXA technique. With respect to the diagnostic criteria for sarcopenia contained in these 13 papers, sarcopenia is defined as appendicular skeletal muscle mass of 1 standard deviation or less than the mean value for young individuals after correction using the square of the individual's height or bodyweight, or appendicular skeletal muscle mass of 2 standard deviations or less than the mean value for young individuals after correction using the square of the individual's height only, or the total skeletal muscle mass percentage of ≤37% for men or 27.6% for women after correction using the individual's bodyweight, or defined using calculation formulae . With regard to obesity, the condition is defined as a BMI of ≥25 kg/m, a BMI of ≥30 kg/m 2 , a body fat percentage in the ≥60th percentile, the upper two quintiles for total body fat percentage of the study population, the highest quintile of the percentage body fat, a waist circumference of ≥90 cm for men or ≥85 cm for women, or based on methods using calculation formulae .…”

Association Between Reduced Daily Steps and Sarcopenic Obesity in Treatment-Seeking Adults With Obesity

“…Based on these considerations, we aimed to assess the prevalence of sarcopenia in treatment-seeking adults of both genders with obesity, using a definition that, in addition to appendicular lean mass (ALM), also includes body weight (18), namely the definition proposed by Oh and colleagues from previous studies, which has been determined to be more clinically useful than other definitions (3,19). Moreover, we also sought to examine any association between SO and a sedentary lifestyleexpressed as a reduction in the number of daily steps-when compared with those without SO.…”
