Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Evaluate enthesitis in psoriatic arthritis using the Leeds Enthesitis Index (LEI), a validated 6-site scoring tool assessing lateral epicondyles, Achilles insertions, and medial condyles of the femur

Each component has a specific meaning:

  • Leeds Enthesitis Index — The leeds enthesitis index recorded for the scenario being assessed.
  • Validated 6-site scoring tool assessing lateral epicondyles — The validated 6-site scoring tool assessing lateral epicondyles recorded for the scenario being assessed.
  • Achilles insertions — The achilles insertions recorded for the scenario being assessed.
  • Medial condyles of the femur — The medial condyles of the femur recorded for the scenario being assessed.

Note: Interpret the lei result against the thresholds and context described above.
