The simple formula for calculating the standard weight of the elderly is: male: height (cm)-105= weight (kg) female: height (cm)-100= weight (kg). For example, an elderly male, height 175 cm, standard weight 175. If his actual weight exceeds 80 kilograms, he is obese; If his actual weight is less than 60 kilograms, he is thin.
In short, the standard weight of more than or less than 5 kg belongs to the normal range; Attention should be paid to the standard weight of more than or less than 5 kg; 10 kg or more, which belongs to obesity and is morbid; Weight less than standard weight 10 kg is emaciation, and neither can be ignored.
