Waist circumference refers to the horizontal circumference of the navel center, or the circumference of the midpoint line between the lowest point of the rib and the upper edge of the iliac crest. It is measured with a soft ruler at the end of exhalation and before inhalation.
Subjects stand with their feet 25 to 30 cm apart and their weight evenly distributed. The measurement position is at the midpoint of the connecting line between the anterior superior iliac crest and the lower edge of the 12 rib in horizontal position. The measuring ruler is attached to the soft tissue, but it cannot be pressed, and the measured value is accurate to 0. 1 cm.

Relationship between waist circumference and health
Waist circumference is a barometer of health. People are very concerned about weight, but they should pay more attention to waist circumference. A large-scale medical survey of more than 350,000 people by European researchers found that if a person's waistline is too large, it is not only unsightly, but also hidden health risks: the risk of premature death of a person with a large waistline can be twice as high as that of a normal person.
Waist circumference may be directly related to the amount of visceral fat in human body, and visceral fat accumulation will lead to diseases. At the same time, the waist and abdomen are also the concentrated places of important organs such as kidney, pancreas and liver. If there is too much fat, it will destroy the pancreatic system and increase the risk of diseases such as hypertension, dyslipidemia, fatty liver and diabetes.
Abdominal obese men are 42% more likely to have heart disease than other men, while women with large waistlines are usually 44% more likely to have heart disease than other women.
Among the eight main known risk factors for cardiovascular diseases, besides overweight and obesity, the other seven are hypertension, smoking, hypercholesterolemia, diabetes, insufficient physical activity, malnutrition and metabolic syndrome.
