Background
BMI is considered by many to be an outdated, inaccurate measure that does not reflect individual health or account for differences in age, ethnicity, disability, or body composition. Its use increases stigma, and can cause harm to children and adults.
It continues to influence access to surgeries, fertility services, pain management, and other essential treatments.
In schools, children are assigned a BMI category yet childhood growth patterns are highly individual, making BMI inappropriate for use with children.
