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.

Each component has a specific meaning:

  • Widespread Pain Index (WPI — The widespread pain index (wpi recorded for the scenario being assessed.
  • 0–19) — The 0–19) recorded for the scenario being assessed.
  • Symptom Severity Scale (SS — The symptom severity scale (ss recorded for the scenario being assessed.
  • 0–12) — The 0–12) recorded for the scenario being assessed.

Note: Interpret the fibromyalgia acr 2010 result against the thresholds and context described above.
