Associations with fracture in patients with diabetes: a nested case-control study

Area of Science:

• Endocrinology
• Metabolic Diseases
• Bone Health

Background:

• Diabetes mellitus is linked to a higher risk of fractures.
• This increased risk is not fully explained by bone mineral density or common risk factors.
• Identifying specific predictors of fracture in diabetes is crucial for prevention.

Purpose of the Study:

• To investigate the association of medication and biochemical markers with fracture risk in diabetes patients.
• To identify modifiable and non-modifiable risk factors for fractures in this population.

Main Methods:

• A nested case-control study design was employed.
• Data were sourced from the Danish National Hospital Discharge Registry, including 24,349 diabetes patients with fractures (cases) and 132,349 without (controls).
• Analysis included patient characteristics, comorbidities, biochemical parameters, and drug usage.

Main Results:

• Increased fracture odds were associated with age, diabetes duration, prior fracture diagnosis, alcohol-related diagnoses, and antiepileptic drug use.
• Higher total cholesterol levels also increased fracture odds.
• Low-density lipoprotein cholesterol levels showed a protective effect, with levels between 3.04-5.96 mmol/L being optimal.

Conclusions:

• Low-density lipoprotein cholesterol levels are a significant factor in understanding fracture risk in diabetes.
• These findings suggest that low-density lipoprotein cholesterol could be incorporated into existing fracture risk assessment models for diabetes patients.
• Further research into biochemical markers and medication effects can refine fracture prediction in diabetes.
