“…ages of 25 years with a peak between 40 and 50 years of age when a decline was registered until 80 years. In a previous study, that evaluated lean body mass index (LBMI) with DXA analysis in a large group of Italian population (large range of BMI and age) a significant increase was reported in both genders, and a significant and progressive decline of FFMI associated with aging was shown [34,37,38].…”

Background & aims: Obesity is characterized by fat mass excess (FM), extra cellular water increase (ECW) and, with ageing, decrease in fat free mass (FFM). The validity of body impedance analysis (BIA) in patients with mild to severe obesity is still debated. The purpose of this study is to describe the Resistance (Rz) and Reactance (Xc) values obtained by Body Impedance Analysis (BIA) in a wide cohort of Italian patients with mild to severe obesity. The secondary endpoint is to describe the resulting body composition values (as percentage and indexes) in this population. Methods: The study enrolled adult in-patients with mild to severe obesity (classified with class I, II and III obesity) undergoing clinical care rehabilitation program for obesity complications and weight loss. BIA values were grouped by sex, BMI and age classes. Results: A total of 8303 patients with obesity, aged 18 to 90 y, were studied. The Resistance (Rz) and Reactance (Xc) were reported by sex, age and BMI classes. In women and men both, the phase angle (PhA) decreases with increasing BMI (kg/m 2 ) and the resulting BIA vector was significantly shifted. The FM index (FMI) was higher (p < 0.0001) in women while FFM index (FFMI) was higher in men (p < 0.0001) and significantly associated with BMI. FFMI decreased with age in both sex (p < 0.0001). Skeletal mass (SM) presents a progressive reduction in relation to age and gender both. Conclusions: The present BIA-based body composition analysis in a wide cohort of mild to severe obese patients revealed a significantly decreased Rz and Xc values with a consequent significant decrease of PhA in a BMI-dependent manner. The body compartments estimation with available equations was BMI, sex and age dependent. These observational results could be the basis for the development of new equations adapted for patients suffering from obesity.

“…Reference values of FFMI estimated for Mongolians (5th-95th percentile of BMI between 18.5-24.9 kg/m2) were relatively higher than values for other countries. Korean researchers defined that FFMI reference values are 16.3-22.3 kg/m2 for men and 13.3-17.8 kg/m2 for women [26]. For Austrians, FFMI is 18.1-21.7 kg/m2 and 15.1-17.0 kg/m2 in men and women, respectively [27].…”

Objectives:The purpose of our study is to examine characteristics of body composition and anthropometric measurements in older Mongolian adults. methods: This cross-sectional study included 268 individuals aged 45 years and older who visited national hospitals over a period of one month. Body weight, BMI, waist circumference (WC) and other body circumferences, and body composition (body fat percentages, fat-free mass index, skeletal mass index) were measured and the Short Physical Performance Battery (SPPB) score was used to test the physical performance. Results: The sample was composed of 73.7% women and 26.3% men, and the mean age was 58.1±8.9. All measurements were relatively higher than the normal range in older Mongolian adults. Obesity in women was relatively higher than men. 77.1% of all participants were obese according to BMI, 92.5% were obese according to body fat percentage, and 96.2% were centrally obese according to WC. Among people aged 45-64 years, prevalence of obesity increased and then decreased in ages 65-74 years. Age was significantly correlated with WC and the SPPB score was indirectly correlated with age (p<0.05). conclusion: Obesity in older Mongolian adults is comparatively higher for women and tends to increase with age.

“…Senescence has led to change from muscular tissue to adipose tissue. C. H. Kim suggested that percent body fat gain with advancing age was due to a reduction of fat free mass rather than a gain in fat mass, especially in men [34].…”
