As long as the waist circumference of the tested population is within the normal range calculated by the formula, the body mass index is almost within the normal range, and the percentage of waist circumference below or beyond the normal range is basically consistent with the corresponding percentage of body mass index decrease or increase.
Waist circumference (WC) refers to the horizontal circumference of the waist passing through the umbilical point (om), which is a comprehensive index reflecting the total amount and distribution of fat. The measurement method recommended by the World Health Organization is that the subjects stand with their feet 25 to 30 cm apart and their weight is evenly distributed.
Waist circumference is a barometer of health. People care about their weight, but they should pay more attention to their waistlines. 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 will not only be unsightly, but also hide 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.
