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

Assess disease severity in ichthyosis vulgaris and related ichthyoses using the Ichthyosis Severity Scale (IHS), evaluating extent, scale severity, erythema, and quality of life impact

Each component has a specific meaning:

  • Ichthyosis Severity Scale — The ichthyosis severity scale recorded for the scenario being assessed.
  • Evaluating extent — The evaluating extent recorded for the scenario being assessed.
  • Scale severity — The scale severity recorded for the scenario being assessed.
  • Erythema — The erythema recorded for the scenario being assessed.
  • Quality of life impact — The quality of life impact recorded for the scenario being assessed.

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

How to Use
