Waist-to-hip ratio (WHR) is the ratio of waist circumference to hip circumference, which is an important indicator to judge central obesity, an effective clue to predict women's fertility and an important measure to evaluate women's charm [1].
Men will give priority to women's looks in short-term mate selection, and have a stronger preference for women with low waist-hip ratio. In a series of cross-cultural studies, men of different ages think that women with waist-hip ratio of 0.7 are the most attractive.
Waist circumference (M62): The circumference passing through the horizontal circumference of the navel center or the connecting line between the lowest point of the rib and the midpoint of the top edge of the iliac crest is measured with a soft ruler and measured before inhaling at the end of expiration.
Hip circumference: the horizontal circumference of the most protruding part of the hip backward, measured with a soft ruler.
waistline
Waist circumference: the average Asian male is 73.35cm and the average Asian female is 65.79cm；; The average male in Europe and America is 83.99cm, and the average female in Europe and America is 72.55cm.
Height waist circumference index = (waist circumference/height) × 100: the average for Asian men is 42.79, and the average for Asian women is 41.34; The average male in Europe and America is 47.84, and the average female in Europe and America is 44.53.
It can be seen that the average waist circumference of men is obviously larger than that of women, and the average (waist circumference/height) × 100 is larger than that of women. In other words, women's waist is thinner.
Hip line
Hip circumference: Asian males average 88.82cm, and Asian females average 91.66 cm [6]; [6]; The average male in Europe and America is 98.37cm, and the average female in Europe and America is 96.69cm[5].
Height and hip circumference index = (hip circumference/height) × 100: the average of Asian males is 52.07, and that of Asian females is 57.78; The average male in Europe and America is 56.03, and the average female in Europe and America is 59.34.
It can be seen that the average hip circumference of men and women is almost the same, and the average (hip circumference/height) × 100 is obviously larger for women than for men. In other words, women's hips are relatively larger.
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 [4]; 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.
