What is optimum BMI? Should this measure be applied to anyone under 18 years old?
The optimum BMI for an adult is between 18 ½ to 25. This measurement should not be applied to anyone that is still growing, thus young people under 16 years old in particular should be measured by a ‘weight for height’ ratio. This type of measurement factors in the young persons age and potential for growth. The most significant indicator of an eating disorder is irregular or infrequent periods.
