1, bust 109.8cm?

2, waist circumference of 75.6cm

3. Hip circumference 1 13.9cm.

4. The standard weight of boys is1.8m..

There are two ways to calculate the standard weight of boys:

One is to subtract 100 or 105 from the height, such as 180. Subtracting 105 is too strict, and subtracting 100 is relatively mild. Subtracting 100, that is, 80 kg, and increasing or decreasing 10% within the range are all allowed and normal changes. If the fluctuation exceeds 10%, such as losing more than 20% of body weight, it is called emaciation, and increasing more than 20% is called obesity.

Another algorithm of standard weight is based on body mass index. The algorithm of body mass index is that the weight is divided by the square of height, in kilograms, and the body mass index is less than 23, which is called standard weight. Boys or girls with a body mass index over 23 are overweight, with 23-24.9 as pre-obesity, over 25 as first-degree obesity and over 30 as severe obesity.

Therefore, the standard weight must be a comprehensive evaluation method, whether it is height minus 105 or body mass index, each has its own advantages and disadvantages, and it must be a comprehensive evaluation.
