Height (cm)- 105 = standard weight (kg).
For example, a man with a height of 170cm should weigh170 (cm)-105 = 65 (kg).
People who exceed the standard weight 10% are overweight, more than 20% are obese, less than 10% are emaciated and less than 20% are emaciated.
The height is 18 1cm, and the standard weight should be181-105 = 76 (kg). The weight of 79Kg is not much different from the standard weight of 76Kg, so it is not considered overweight.
Extended data:
Asian standard
The traditional WHO adult obesity standard is below 30, but the Asian adult index has recently been changed to 27.5. Asian adults with a body mass index of 23 are now considered overweight, while the ideal index is 18.5 to 22.9.
The value of children's body mass index
Children's body mass index values are not only applicable to adults. For growing children, we can also use their body mass index to calculate whether they are overweight. The above formula for calculating body mass index is also applicable to people aged 2-20, but their overweight and body mass index are not determined by a fixed body mass index value.
This is because children in different regions grow at different speeds, and it is easy to make wrong judgments if a fixed value is used. Many countries and regions make statistics on the height and weight of local children every year. These statistics can be converted into body mass index values, and then the distribution of body mass index values of local children can be counted.
