How do you calculate BMI with age?

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Do you adjust BMI for age?

Adults with low and very high BMIs are at a higher relative mortality risk compared to those with BMIs of 18.5 or greater and less than 30.0 (Strawbridge et al., 2000). For adults, BMI is not age- or gender-specific as it is for children and adolescents.

Is BMI based on age?

BMI cannot be fully accurate because it is a measure of excess body weight, rather than excess body fat. BMI is further influenced by factors such as age, sex, ethnicity, muscle mass, and body fat, and activity level, among others.

How do I calculate BMI manually?

Then, calculate BMI by dividing weight in pounds (lb) by height in inches (in) squared and multiplying by a conversion factor of 703.
