GPT and Insulin resistance: Cui et al. also reported associations between NAFLD and lower BMD in men and postmenopausal women in China [20]; this association was observed after adjusting for weight, body mass index (BMI), waist size, high density lipoprotein (HDL) concentration, and ALT, but it became non-significant after further adjusting for insulin resistance (HOMA-IR), suggesting an important role of insulin resistance in the NALFD-BMD association.
