Visceral Adipose

Introduction: Excess Visceral Adipose Tissue (VAT) is linked to cardiometabolic risk in adolescents. VAT is mainly measured using Magnetic Resonance Imaging (MRI), yet dual-energy x-ray absorptiometry (DXA) is more affordable and available. The purpose was to compare VAT from MRI and DXA in adolescents. Methods: Adolescents 10-16 years of age were recruited. Abdominal MRI was performed using a General Electric (GE) Signal Excite scanner (3.0 Tesla; GE Medical Systems) with IDEAL-IQ imaging software. A series of scans between specific points on the liver and kidney were conducted. A trained technician manually drew VAT and used additional calculations to determine VAT volume (L). A whole-body DXA (GE iDXA scanner) was performed and software calculated VAT within the android region. Paired samples t-tests were used to determine differences between VAT values, within sex, race (White, African American, and Other race), and BMI categories (normal, overweight, and obese). VAT values were standardized to a mean of zero and unit standard deviation and compared with a Bland Altman plot. Results: A total of 330 adolescents participated. The mean age was 12.6±1.9 years, and the sample was 52.3% female, 58.5% White, 14.7% overweight (14.7%), and 33.5% obese. Average VAT from MRI (0.58±0.47 L) and DXA (0.35±0.41 L) significantly differed ( p =0.001). The error and absolute error were -0.23 ±0.20 L and 0.23±0.20 L respectively, with DXA measuring lower than MRI. DXA values were significantly lower from MRI values for each sex, race, and BMI categories ( p <0.01 for all). DXA values were closest to MRI values in African American adolescents (-0.14 ±0.20 L) and furthest away for those who had overweight (-0.31±0.17 L). All standardized values fell within ±1.96 standard deviations (Figure 1). Conclusions: In this sample, DXA measured VAT values were consistently lower overall and in subgroups compared to MRI. In general, DXA values were not comparable to MRI values.

Ross, Robert, John Rissanen, Heather Pedwell, Jennifer Clifford, and Peter Shragge. Influence of diet and exercise on skeletal muscle and visceral adipose tissue in men. J. Appl. Physiol. 81(6): 2445–2455, 1996.—The effects of diet only (DO) and diet combined with either aerobic (DA) or resistance (DR) exercise on subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), lean tissue (LT), and skeletal muscle (SM) tissue were evaluated in 33 obese men (DO, n= 11; DA, n = 11; DR, n = 11). All tissues were measured by using a whole body multislice magnetic resonance imaging (MRI) model. Within each group, significant reductions were observed for body weight, SAT, and VAT ( P < 0.05). The reductions in body weight (∼10%) and SAT (∼25%) and VAT volume (∼35%) were not different between groups ( P > 0.05). For all treatments, the relative reduction in VAT was greater than in SAT ( P < 0.05). For the DA and DR groups only, the reduction in abdominal SAT (∼27%) was greater ( P < 0.05) than that observed for the gluteal-femoral region (∼20%). Conversely, the reduction in VAT was uniform throughout the abdomen regardless of treatment ( P > 0.05). MRI-LT and MRI-SM decreased both in the upper and lower body regions for the DO group alone ( P < 0.05). Peak O2 uptake (liters) was significantly improved (∼14%) in the DA group as was muscular strength (∼20%) in the DR group ( P< 0.01). These findings indicate that DA and DR result in a greater preservation of MRI-SM, mobilization of SAT from the abdominal region, by comparison with the gluteal-femoral region, and improved functional capacity when compared with DO in obese men.

The relationship between skeletal muscle mass, visceral adipose tissue, insulin sensitivity, and glucose tolerance was examined in 214 overweight or obese, but otherwise healthy, men (n = 98) and women (n = 116) who participated in various exercise and (or) weight-loss intervention studies. Subjects had a 75 g oral glucose tolerance test and (or) insulin sensitivity measures by a 3 h hyperinsulinemic–euglycemic clamp technique. Whole-body skeletal muscle mass and visceral adipose tissue were measured using a multi-slice magnetic resonance imaging protocol. Total body skeletal muscle mass was not associated with any measure of glucose metabolism in men or women (p > 0.10). These observations remained independent of age and total adiposity. Conversely, visceral adipose tissue was a significant predictor of various measures of glucose metabolism in both men and women with or without control for age and (or) total body fat (p < 0.05). Although skeletal muscle is a primary site for glucose uptake and deposition, these findings suggest that unlike visceral adipose tissue, whole-body skeletal muscle mass per se is not associated with either glucose tolerance or insulin sensitivity in overweight and obese men and women.
