Height (Ht), weight, and waist circumference (WC) were measured. The body mass index (BMI), WC, and the WC\/Ht ratio were used as traditional anthropometric indices. A body shape index (ABSI) and the body roundness index (BRI) were calculated as novel indices. Indices of SI (Matsuda index and 1\/homeostasis model assessment of insulin resistance) were calculated and compared with anthropometric indices.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The ABSI showed a weak correlation with SI indices in all groups. The BRI showed almost the same correlation with SI indices as the BMI, WC, and WC\/Ht in all groups. The inverse correlation between each of the anthropometric indices other than ABSI and SI indices was weak in young persons, at 0.16\u20130.27 (Spearman's \u03c1 values), but strong in middle-aged persons, at 0.38\u20131.00. On receiver-operating characteristic (ROC) curve analysis for detection of insulin resistance, the ABSI had a lower area under the ROC curve (AUC) than the other anthropometric indices, and the BRI and the WC\/Ht ratio showed similar AUCs. The AUCs for the BRI and WC\/Ht ratio were the highest in middle-aged men with NGT and glucose intolerance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The BRI, not the ABSI, was better correlated with SI in young and middle-aged Japanese persons.
