Chest circumference = height (cm) ×0.535, waist circumference = height (cm) ×0.365 and hip circumference = height (cm) ×0.565. According to the statistical results, the "measurements" are less than 5 cm, indicating that they are too slim (thin); More than 5 cm indicates that it is too plump (overweight). Professional female models are measured differently. Due to professional needs, their measurement standards have a certain gap with the normal standards.
waist hip ratio
Waist-to-hip ratio = waist circumference/hip circumference: the average Asian male is 0.8 1, and the average Asian female is 0.73; European and American men average 0.85, and European and American women average 0.75. It can be seen that the average waist-hip ratio of men is obviously greater than that of women, and the gender difference is obvious. Waist-to-hip ratio is an index to predict obesity in this study.
The smaller the proportion, the healthier it is. This is a better way to predict whether a person is obese and whether he is at risk of heart disease. A large waistline indicates that there is fat in the abdomen, which is a signal of greater danger. Moreover, a person's hip circumference is large, which shows that his lower body is muscular and beneficial to people's health.
