Calculation basis and official references
Reviewed on:
This calculator is not a diagnosis, treatment plan, or prescription. Please consult a qualified clinician about your medical decisions.
Formula basis
Uses sex and age band (six bands from 19-29 to 70+) as keys into a reference table, then computes the difference from the entered height/weight.
Calculation method
Looks up the national reference average height and weight for adults in the selected age band and sex, and compares them with the entered values.
Exclusions and checks required
- The National Health and Nutrition Survey is an annual sample survey, so figures vary somewhat year to year.
- The '19-29' band label is used for a slightly wider age range than the survey's official '20-29' category.
Example input:：Example: man in his 40s, height 175cm, weight 75kg
sex- Male
band- 40-49
height- 175
weight- 75
The difference from the reference average (171.2cm/70.4kg) does not assess an individual's health status.
