“…In our research centre, the bioelectrical impedance analyser was validated using dual-energy X-ray absorptiometry (DEXA) in overweight and obese individuals. Also, a highly linear relationship between fat mass assessed by the bioelectrical impedance method and that assessed by DEXA has been documented by others (Shafer, Siders, Johnson, & Lukaski, 2009;Shaikh, Crabtree, Shaw, & Kirk, 2007).…”

Omentin-1 is a newly discovered protein expressed and secreted from visceral adipose tissue that increases insulin sensitivity.We examined the effects of 12 weeks of aerobic training on serum omentin-1 concentrations together with cardiovascular risk factors in overweight and obese men. Eighteen overweight and obese participants (age 43.1 ± 4.7 years, BMI ≥ 25 kg . m ⁻² ) were assigned to exercise training (n = 9) and control (n = 9) groups. A matched control group of normal weight participants (n = 8; age 42.2 ± 3.8 years, BMI < 25 kg . m ⁻² ) were also recruited for baseline comparison. The obese exercise group participated in 12 weeks of progressive aerobic training 5 days a week. Measures of serum omentin-1, insulin resistance, lipid profiles, blood pressure, and body composition were obtained before and after the 12 weeks. At baseline, normal weight participants had significantly higher serum omentin-1 concentrations than overweight and obese participants, and there were inverse correlations between omentin-1 and each of waist circumference, fasting glucose, insulin resistance, total cholesterol,triglyceride, and systolic blood pressure (P < 0 .05). After the aerobic training, waist circumference, percent body fat, fasting glucose, insulin resistance, triglyceride, total cholesterol, low-density lipoprotein cholesterol, and systolic blood pressure were all significantly decreased (P < 0.05). In contrast, serum omentin-1 concentration was significantly increased after the aerobic programme (P < 0.05), and correlated with changes in insulin resistance (r = − 0.67, P= 0.04), glucose (r = − 0.65, P = 0.05), waist circumference (r = −70, P = 0.03), and aerobic fitness r = −.68, P = 0.04). Aerobic training resulted in an improvement in cardiometabolic risk factors in obese participants, and this improvement was accompanied by increased omentin-1 concentrations.

“…BP and hypertension correlates with FM, seems to be valid. Another limitation of our investigation is the missing gold standard method, such as dual energy X-ray absorptiometry [29] for FM evaluation when comparing BIA values versus BMI values. However, we have shown that BIA is able to demonstrate the acknowledged divergence of FM during puberty in healthy boys and girls, whereas this was not possible with BMI.…”

Correlation between fat mass and blood pressure in healthy children

et al. 2009

Obesity is a well-known risk factor for arterial hypertension. The aim of this study was to analyze which surrogate marker of adiposity, i.e., body mass index (BMI) or fat mass (FM), as measured by bioimpedance analysis (BIA), best correlated with blood pressure in healthy children. Body weight, height, and casual blood pressure (BP) were measured in 193 healthy children (103 boys), aged 8-16 years. Body composition was determined by BIA. The correlation between BMI and age was linear, whereas the correlation between percentage of FM and age was nonlinear and it was different in boys and girls. Blood pressure standard deviation scores (SDS) correlated with FM SDS (BIA) over the entire normal range (systolic: r = 0.26, p = 0.002; diastolic: r = 0.33, p < 0.01). An evaluation of the children based on BP (three groups: BP < 50th percentile, 50th < BP > 95th percentile; BP > 95th percentile) revealed that hypertensive children had a higher BMI (17.6 vs. 19.4 vs. 26.2 kg/m(2), respectively) and a greater FM (14.0 vs. 16.8 vs. 30.2%, respectively). In conclusion, the divergence in FM in healthy boys and girls can be determined by BIA but not by BMI. In healthy children, BP within the entire normal range correlated with FM, children with established hypertension presented with a significantly higher FM. The study points to FM as an important determinant of BP pressure in obese and non-obese children.

“…Although measuring skinfold thickness is a practical method, inter-observer variability and need for qualified staff limits its widespread use and the reliability of this method in some situations. Using bioelectrical impedance (BIA) measurements to assess the quantity of body fat accumulation and segmental distribution of this fat content is considered relatively expensive when compared to measuring skinfold thickness, but determining body fat with BIA is much more practical, provides segmental distribution, and can easily be used in population screening as well as used in daily practice [19,21].…”

Body fat reference curves for healthy Turkish children and adolescents

Since BMI may not always reflect body fat content, direct assessment of adiposity by a practical method would be significantly useful for clinical decisions. Therefore, this study provides normative data for body fat percentage in healthy Turkish children and adolescents. To this goal we used a practical and clinically applicable method. These references can be useful for evaluation of overweight and obesity.
