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 body mass index (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), BMI, waist-to-hip-ratio (WHR), visceral adiposity index (VAI), body adiposity index (BAI), and waist-to-height ratio (WHtR) were assessed. Using bioelectrical impedance (BIA, TANITA MC 180M) the following parameters were obtained: the level of visceral adipose tissue (VAT) and body fat percentage (FM%). 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 the studied indicators: WC, WHtR, BAI, VAI, and BMI, positively correlated with VAT estimated by bioimpedance, but only VAI, WC, and WHtR were strongly associated with glucose and lipid disturbances in the obese. BAI and BMI correlated with total FM%, while WC, WHtR, and VAI correlated with total body weight.
The results indicate that VAI, WC, and WHtR can be useful in the assessment of increased VAT accumulation associated with disturbances in glucose and lipid metabolism. BAI should be calculated separately for each sex, then it could be also useful for the prediction of disturbances in glucose metabolism. However, further studies are needed to recognise cut-off values for BAI, as a marker of body fatness, associated with adverse health effects.
本研究旨在探讨肥胖个体中新的肥胖相关指标、人体测量学和生化参数与身体成分之间的关系。
研究组由72名女性和34名男性组成，年龄为39.0±5.9岁，平均体重指数（BMI）为32.6±2.4kg/m²，因体重减轻入院。对所有参与者评估体重（BW）、身高、腰围（WC）、臀围（HC）、BMI、腰臀比（WHR）、内脏脂肪指数（VAI）、身体脂肪指数（BAI）和腰高比（WHtR）。使用生物电阻抗法（BIA，TANITA MC 180M）获得以下参数：内脏脂肪组织（VAT）水平和体脂百分比（FM%）。测定血清总胆固醇（TC）、高密度脂蛋白胆固醇（HDL）、低密度脂蛋白胆固醇（LDL）、甘油三酯（TG）、葡萄糖、胰岛素和胰岛素抵抗（HOMA-IR）的浓度。
观察到几乎所有研究指标：WC、WHtR、BAI、VAI和BMI，均与生物阻抗估计的VAT呈正相关，但只有VAI、WC和WHtR与肥胖者的血糖和脂质紊乱密切相关。BAI和BMI与总FM%相关，而WC、WHtR和VAI与总体重相关。
结果表明，VAI、WC和WHtR可用于评估与糖脂代谢紊乱相关的VAT积累增加。BAI应按性别分别计算，这样也可能有助于预测糖代谢紊乱。然而，需要进一步研究以确定BAI作为身体肥胖标志物与不良健康影响相关的临界值。
