Background:
Bone metabolism can be influenced by type 2 diabetes mellitus (T2DM). 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.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
