Summary

Obesity and frailty have been variably defined; however one of the most useful measures is the body mass index (BMI), which is the weight of an individual in kilograms divided by the height in meters squared. BMI units are kg/m2; the normal range lies between 18.5 and 24.9 kg/m2, with underweight individuals falling below 18.5 kg/m2 and overweight or obese above 30. Usually, the units for BMI are left off the value.
