Association Analysis of Insulin Resistance and Osteoporosis Risk in Chinese Patients with T2DM

摘要

Background: To explore the relationship between insulin resistance and osteoporosis risk in Chinese patients with type 2 diabetes mellitus (T2DM). Methods: A total of 234 T2DM patients were retrospectively analyzed, and their lumbar bone mineral density (BMD) and insulin resistance using C-peptide-based homeostasis model of insulin resistance [HOMA-IR (CP)] were assessed. Univariate and multivariable logistic regression methods were used to evaluate the association between HOMA-IR (CP) and osteoporosis, and subgroup analysis was performed on female and male patients. Results: After fully adjusting the covariates, the association between HOMA-IR (CP) and osteoporosis was only significant in female patients (P = 0.022); the interaction effect with gender was significant (P for interaction 4.00, the risk of osteoporosis increased significantly, with OR = 26.88 (95% CI: 2.75– 262.69, P = 0.005). The relationship between insulin resistance and osteoporosis risk in T2DM patients is significantly affected by gender. Conclusion: The higher the degree of insulin resistance in female patients, the greater the risk of osteoporosis, but the two are not linearly associated.
