Thyroid hormones and thyroid hormone sensitivity indices correlate with volumetric bone mineral density and vertebral fracture risk among the osteoporotic population in northern China
Clinical Report: Associations Between Thyroid Hormones and Vertebral Fracture Risk
Overview
This study investigates the associations between thyroid hormones, sensitivity indices, volumetric bone mineral density (BMD), and vertebral fracture risk in osteoporotic individuals over 50 in Northern China. Elevated TT3 levels were linked to increased fracture risk, while TSH showed a positive association with lumbar QCT-BMD.
Background
Osteoporosis is a significant public health issue, particularly among aging populations, leading to increased fracture risk. Thyroid hormones are known to influence bone metabolism, and their dysregulation can exacerbate bone density loss. Understanding the relationship between thyroid function and bone health is crucial for developing effective management strategies for osteoporosis.
Data Highlights
Measure
Fracture Group
Non-Fracture Group
P-value
TT3 (nmol/L)
1.98 [1.60, 2.89]
1.76 [1.50, 1.91]
< 0.001
TT4 (nmol/L)
89.50 [39.65, 101.00]
103.00 [85.60, 115.00]
< 0.001
Key Findings
Higher TT3 levels were significantly associated with increased vertebral fracture risk (OR 1.02, P = 0.018).
TT4 levels were significantly lower in the fracture group compared to the non-fracture group (P < 0.001).
TSH positively correlated with lumbar QCT-BMD (β 0.89, P = 0.034).
FT4/FT3 and FT3 were positively associated with lumbar QCT-BMD but showed nonlinear negative associations in RCS analysis.
Significant interaction effects for FT4/FT3 were observed in gender and age-specific analyses.
Clinical Implications
Clinicians should consider monitoring thyroid hormone levels in osteoporotic patients, particularly those at risk for vertebral fractures. The findings suggest that elevated TT3 may serve as a risk factor for fractures, highlighting the need for careful management of thyroid function in this population.
Conclusion
The study underscores the importance of thyroid hormones in assessing fracture risk and bone density in osteoporotic individuals. These findings may inform future strategies for fracture prevention in at-risk populations.
