Depression and the Risk of Fractures in Later Life: the Health In Men Cohort Study

Area of Science:

• Gerontology
• Psychiatry
• Epidemiology

Background:

• Fractures are a significant cause of disability in older adults.
• Depressive symptoms are linked to a higher risk of fractures.
• The causal relationship between depression and fractures requires further investigation.

Purpose of the Study:

• To determine if the association between depressive symptoms and fractures is causal or due to confounding factors.
• To investigate the risk of incident fractures in older men with a history of depression.

Main Methods:

• A cohort study of 4224 men aged 70-88 years was conducted over 17 years.
• Depression was identified via diagnosis or Geriatric Depression Scale scores.
• Fracture data and potential confounders (e.g., falls, medications, vitamin D) were analyzed.

Main Results:

• 911 participants (21.6%) experienced fractures.
• Both past and current depression were associated with increased fracture risk (ORs 1.41-1.64).
• Competing risk regression confirmed depression's association with novel fractures (SHRs 1.27-1.29).

Conclusions:

• Clinically significant depression is associated with a higher risk of future fractures in older men.
• While confounding factors exist, depression warrants clinical attention for fracture risk management.
• Integrated management plans for both depression and fracture risk are recommended.
