Popis: OBJECTIVE The clinical consequences of insulin resistance and hyperinsulinemia on marrow lipid remain elusive. We aimed to explore the effects of anthropometric and biochemical measures, that is, estimates of insulin resistance, on marrow lipid accumulation in nondiabetic postmenopausal women using magnetic resonance (MR) spectroscopy. METHODS The study participants were 91 nondiabetic postmenopausal women. Marrow fat fraction (FF) at the L3 vertebral body by single-voxel MR spectroscopy and bone mineral density (BMD) by dual-energy x-ray absorptiometry were measured. Their glucose and lipid metabolism were determined by biochemical analysis, and their insulin sensitivity was evaluated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). RESULTS Adjusted for multiple covariates including age, years since menopause, body mass index, alcohol intake, tobacco use, physical activity, and serum lipid profile, the mean FF was significantly increased, and BMD at the lumbar spine, femoral neck, and total hip decreased as quartiles of HOMA-IR increased (P for trends
