4.2 Judgment of overweight and obesity

Use the table 1 boundary value for overweight judgment. where the BMI is greater than or equal to the corresponding gender, age group "overweight" boundary point and less than the "obesity" threshold is overweight.

Use the boundary value of Table 1 for obesity judgment. where the BMI is greater than or equal to the corresponding gender and age group, the obesity threshold is fat.

4.3 Overweight and obesity screening instructions and technical requirements

4.3.1 Use of BMI

In the BMI calculation formula, the height and weight should be measured and measured according to the equipment and methods specified in GB/T 26343.

Do not use questionnaires, self-reports, etc. The height is measured in "cm" and recorded in one decimal place.

When BMI is converted to "meter".

BMI retains a decimal number and compares it with Table 1 to determine overweight and obesity.

4.3.2 Calculation method of age

The age is in half-years and all ages are used. The chronological age is calculated as the date of the survey minus the date of birth.

The number of years of experience that has been experienced since the birth of the calculation is in the standard of half a year.

Example. A student's birthday is September 25, 2000, and the survey date is September 24, 2010.

9.5 years old; if the survey date is September 25, 2010, the actual age is 10.0 years; if the survey date is 2011 on March 25th, the age of the child was 10.5 years old.
