Abstract

The aim of this study was to examine the relationship between new obesity-related indexes, anthropometric and biochemical parameters and body composition in individuals with obesity.The study group consisted of 72 women and 34 men aged 39.0 ± 5.9 years with a mean BMI of 32.6 ± 2.4 kg / m2, admitted for body weight reduction. In all participants body weight (BW), height, waist circumference (WC), hip circumference (HC), body mass index (BMI), waist-to-hip-ratio (WHR), visceral adiposity index (VAI), body adiposity index (BAI), waist-to-height ratio (WHtR) were assessed. Using bioelectrical impedance (BIA, TANITA MC 180M) the following parameters were obtained: VAT (the level of visceral adipose tissue), FM % (body fat percentage). Serum concentrations of total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), triglycerides (TG), glucose, insulin and insulin resistance (HOMA-IR) were determined.It was observed that almost all studied indicates; WC, WHtR, BAI, VAI and BMI positively correlated with visceral adipose tissue (VAT) estimated by bioimpedance, but only VAI, WC, WHtR were strongly associated with glucose and lipid disturbances in obese. BAI and BMI correlated with total body fat percentage, while WC, WHtR and VAI with total body weight.The results indicate that VAI, WC and WHtR can be useful in assessment of increased visceral adipose tissue accumulation associated with disturbances in glucose and lipid metabolism. BAI should be calculated separately for each sex, then could be also useful to predict disturbances in glucose metabolism. However, further studies are needed to recognize cut-off values for BAI, as a marker of body fatness, associated with adverse health effects.
