Objective:

To investigate factors associated with the risk of incident hip or knee replacement in a population-based cohort.

Approach:

Key Findings:

• Each 1 kg/m² decrease in BMI was associated with a 4% lower risk of joint replacement.
• Lower spine T-score correlated with a 16% lower risk.
• Lower procollagen type 1 N-terminal propeptide (P1NP) level linked to a 31% lower risk.
• No history of falls associated with a 26% lower risk.
• No history of cancer linked to a 34% lower risk.

Interpretation:

Remove editorial interpretations and ensure it reflects only the source material.

Limitations:

• Several associations did not hold across all sensitivity analyses.
• The study could not determine the specific indications for each surgery.
• Findings related to cancer and dietary calcium were not robust across all analyses.
