Background

As the metabolic significance of sarcopenic obesity (SO) is revealed, finding an appropriate index to detect SO is important, especially for type 2 diabetes mellitus (T2DM) patients with accompanying metabolic dysfunction.

Methods

Participants (n= 515) from the Korea Guro Diabetes Program were included to compare how well waist circumference (WC), waist hip ratio (WHR), waist height ratio (WHtR), and the weight-adjusted waist index (WWI) predict SO in newly diagnosed T2DM patients. Sarcopenia was defined based on guidelines from the 2019 Asian Working Group for Sarcopenia as both low muscle mass (appendicular skeletal muscle [ASM]/height 2< 7.0 kg/m 2 for men,< 5.4 kg/m 2 for women) and strength (handgrip strength< 28.0 kg for men,< 18.0 kg for women) and/or reduced physical performance (gait speed< 1.0 m/sec). Obesity was defined as a WC≥ 90 cm in men and≥ 85 cm in women …
