Summary Objectives To create normative data for visceral adipose tissue ( VAT ) derived from the GE Lunar iDXA specific to sex and age cohorts for adults in the United States ( US ). Methods A cross‐sectional analysis of 649 adults were evaluated [Mean ± SD (Range): Males: n = 351; Age = 33·2 ± 17·4 years (18–75 years); Body mass index ( BMI ) = 26·5 ± 5·4 kg·m −2 (17·5–44·2 kg·m −2 ); Females: n = 298; Age = 28·5 ± 14·3 years (18·0–75·0 years); BMI =25·8 ± 6·9 kg·m −2 (17·9–54·8 kg·m −2 )]. From a total body dual‐energy X‐ray absorptiometry ( DXA ) scan, VAT mass (kg) and volume (cm 3 ) were quantified from the software‐delineated region‐of‐interest. The relationship between VAT and age was evaluated using regression analysis. Separate VAT percentiles were stratified by age range (18–19 years; 20–24 years; 25–50 years; 50+ years) for males and females. Results In both males and females, there was a positive, non‐linear relationship between VAT and age ( R 2 = 0·47–0·49; P <0·0001). In males, the 50th percentile for VAT mass and volume, stratified by age was: 18–19 years (0·18 kg; 185·67 cm 3 ), 20–24 years (0·25 kg; 261·21 cm 3 ), 25–49 years (0·71 kg; 746·27 cm 3 ) and 50+ years (1·62 kg; 1708·36 cm 3 ). In females, the 50th percentile for VAT mass and volume, stratified by age was: 18–19 years (0·04 kg; 44·90 cm 3 ), 20–24 years (0·06 kg; 59·57 cm 3 ), 25–49 years (0·55 kg; 579·28 cm 3 ) and 50+ years (1·21 kg; 1284·59 cm 3 ). Conclusion These normative values provide a reference for VAT mass and volume in US adults 18–75 years of age obtained using the GE Lunar iDXA . Measures of VAT provide important information about metabolic and cardiovascular health risk beyond that of BMI and per cent body fat.
