However, the relationship between T2DM and bone mineral density (BMD) remains inconsistent. This study explored the differences in BMD in middle-aged adults with and without T2DM.Methods: We conducted a cross-sectional study of 4986 participants aged 40– 59 years who participated in the National Health and Nutrition Examination Survey (NHANES) 2011– 2018. We performed multivariable logistic regression models to evaluate the associations between T2DM status, serum glucose, glycohemoglobin (HbA1c), disease duration and lumbar BMD.Results: There was a positive association between T2DM status and lumbar BMD in all three models (model 1: β=0.039, 95% CI: 0.025– 0.052; model 2: β=0.045, 95% CI: 0.031– 0.059; model 3: β=0.035, 95% CI: 0.014– 0.055). In the subgroup analysis stratified by gender, this positive association existed in both gender after adjusting for confounders (males: β=0.033, 95% CI: 0.003– 0.062; females: β=0.035, 95% CI: 0.008– 0.062). Besides, there were no significant associations of serum glucose, HbA1c, disease duration with lumbar BMD in both genders with T2DM.Conclusion: This study indicated that middle-aged adults with T2DM had significantly higher lumbar BMD compared with those without DM.Keywords: diabetes, glucose, HbA1c, bone health, NHANES
