In China, the suitable waist circumference for adults is 85cm for men and 80cm for women. Once this standard is exceeded, the risk of chronic diseases such as cardiovascular and cerebrovascular diseases and diabetes will increase greatly.
85cm for male and 80cm for female. This safe waist circumference was measured by the China Obesity Expert Group on the waist of 300,000 adults in 2/kloc-0 provinces, municipalities and autonomous regions.
The ratio of height to waist circumference affects a person's health. British scientists have found that the waist circumference is half the height of the healthiest person. Researchers from Cass Business School of City University of London found that if the ratio of waist circumference to height exceeds 80%, people's life expectancy will be reduced by as much as 20 years. Therefore, in order to maintain health and longevity, this ratio should be less than 50%.
Extended data:
Height waist circumference index = (waist circumference/height) × 100, waist-hip ratio = waist circumference/hip circumference. These two indexes are higher in men than in women, and the difference is significant. Height and hip circumference index = (hip circumference/height) × 100, height and thigh circumference index = (thigh circumference/height) × 100, and thigh length index = (thigh circumference/thigh length) × 100. These three indexes are higher for women than for men, with significant differences.
Standard waist circumference calculation method, male: height (cm)÷2- 1 1(cm), female: height (cm) ÷ 2- 14 (cm), plus or minus 5% is the normal range. 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, the percentage of waist circumference below or beyond the normal range is basically consistent with the corresponding weight, and the index percentage decreases or increases.
