The BMI is generally is used for the purpose of obtaining the public health for the survey and to assess the condition of the general public. It used for the medical purpose to determine the health of the patient and to recommend to suitable diet to maintain their BMI value and also for the purpose of the screening process in some professions. A study published that based on the BMI value that overweight and normal people have same death rate while the obese and underweight people have a higher death rate.
Some of the institutes and individuals argue that the errors in the BMI calculations are more significant and so they should not be used. They argue that BMI is convenient ,but it is very inaccurate to be forced on the people and should be immediately reconsidered. The errors in the BMI calculation will lead short people into thinking that they are thin and tall people into thinking that they fatter than they are. The BMI value has increased approximately 10 % for taller people and 10 % of the BMI value is decreased for the short people. It is unclear where the threshold should be set for the overweight and obesity since it has been changing continuously over the years.
