Standard weight table for boys

When it comes to weight, many people say that women are particularly concerned about weight changes, and many women hope to be slimmer and more beautiful. For men, they also pay attention to weight. A fat body looks ugly. The ratio of weight to height can also reflect a person's physical condition. Being overweight or underweight is not conducive to the healthy development trend of the body. So, what is the normal range of height and weight index for boys? Today, the editor will explain these doubts to everyone.

Height and weight index

The definition of body mass index was first clearly proposed by the Danish generalist Kettler in the mid-to-late 19th century. Its definition is as follows: body mass index (BMI) = weight (kg) / height m2 (m), such as: 75kg/1.8/1.8 = 23.15.

It is a number calculated by dividing the weight in kg by the height in meters per square meter. It is currently a common international standard for measuring body fatness and health. It is suitable for statistical analysis. When we need to compare and analyze the health effects of a person's weight on people of different heights and widths, the BMI value is a neutral and reliable indicator.

The original design concept of BMI is a statistical analysis tool for scientific research on the health of the general public. When we want to know whether obesity is the cause of a certain disease, we can calculate the patient's height and weight into BMI value, and then find out whether there is a linear relationship between the standard value and the incidence rate.

However, with the technological innovation, the current BMI value is only a standard value. To truly measure whether a patient is obese, it is necessary to measure the patient's characteristic impedance from micro-electrical engineering to infer the thickness of the patient's body fat. Therefore, the role of BMI has gradually changed, from its main use in medicine to becoming a weight loss indicator for ordinary people.
