Diabetes and Femoral Fracture Patterns: A Nationwide Registry Study (1997–2021)

Diabetes CarePublished Nationwide registry-based cohort study

Authors' conclusion

Type 1 diabetes was associated with increased incidence of femoral fractures and slightly higher odds of ST/FS than hip fractures after adjustment.

Study context

Population
Adults ≥65 years old, Danish registries, 1997–2021
Exposure
T1D and T2D vs no diabetes
Outcome
Incidence rates (IRs) and incidence rate ratios (IRRs) of subtrochanteric/femoral shaft (ST/FS) and hip fractures
Methodological detailsDanish registries, 1997-2021
  • Danish registries
  • 1997-2021

Main finding

As reported in the abstract

T1D
IRR (ST/FS) 2.53; P < 0.001
T1D
IRR (hip) 2.17; P < 0.001
