Common methods for measuring obesity and anthropometric standards

Common methods for checking obesity. Although obesity is defined as body fat accounting for more than 20% of body weight, there is currently no direct method to measure the total amount of body fat. All methods are currently measured indirectly. Some use general measuring instruments, such as scales, tape measures, and calipers, while others use specialized instruments, such as ultrasound, CT scans, MRI, and precision instruments for measuring radioactive elements. Below are some commonly used methods. General methods: 1. Standard weight method. A person's height and weight, and the composition of various body parts, are in a certain proportion.

Therefore, ideal weight can be calculated based on measurements of height and weight, and then compared with the subject's actual weight to assess obesity. Some anthropometric results reflect overall obesity, while others reflect localized fat accumulation (i.e., fat distribution). Most anthropometric methods only calculate weight and do not truly reflect the amount of body fat. Therefore, assessing obesity based on anthropometric results must be combined with visual observation for a comprehensive judgment. The standard weight method is determined based on a relatively constant proportional relationship between height and weight in men and women. This method is simple, but only provides a rough estimate.

The calculation formulas are as follows: ① Standard weight (kg) = Height (cm) - 100. This formula is simple and practical. ② Standard weight for men (kg) = Height (cm) - 105; Standard weight for women (kg) = Height (cm) - 100. This formula is more suitable for Asian countries. ③ Standard weight (kg) =
