Prader-Willi Syndrome Obesity Risk and GH Response Calculator

Calculates obesity risk trajectory in Prader-Willi syndrome using genotype (deletion vs UPD), age at hyperphagia onset, BMI trajectory, and growth hormone therapy response monitoring.

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

Calculates obesity risk trajectory in Prader-Willi syndrome using genotype (deletion vs UPD), age at hyperphagia onset, BMI trajectory, and growth hormone therapy response monitoring

Each component has a specific meaning:

  • Genotype — The genotype recorded for the scenario being assessed.
  • Age at hyperphagia onset — The age at hyperphagia onset recorded for the scenario being assessed.
  • BMI trajectory — The bmi trajectory recorded for the scenario being assessed.
  • Growth hormone therapy response monitoring — The growth hormone therapy response monitoring recorded for the scenario being assessed.

Note: Interpret the pws obesity risk result against the thresholds and context described above.

How to Use

Enter the genotype, age at hyperphagia onset, BMI trajectory, growth hormone therapy response monitoring for the scenario you are assessing. Calculates obesity risk trajectory in Prader-Willi syndrome using genotype (deletion vs UPD), age at hyperphagia onset, BMI trajectory, and growth hormone therapy response monitoring. Use the pws obesity risk result to inform your calculation.
