What is the standard measurement scale?

The standard indexes of girlhood measurements are: bust = height (cm) *0.535, waist = height (cm) *0.365, hip = height (cm) *0.565. Male standard measurements: chest = height *0.48, waist = height *0.47, hip = height *0.5 1. Men and women of the same nationality are correlated in height, weight and other parameters, which can be converted to each other. Japanese scholar Masahiro Oshima got the conversion coefficient of female figure from male data: the chest circumference coefficient is 90%, the waist circumference coefficient is 89%, and the hip circumference coefficient is 102%.

Fat distribution

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.

In other words, men of the same height have thicker waists, while women have wider hips and thicker thighs. This is related to the gender difference in body fat distribution. Estrogen inhibits fat accumulation in the upper abdomen and increases fat accumulation in the buttocks and thighs.

Pear-shaped and hourglass-shaped women with thin hips and thick thighs are healthier and live longer than rectangular, apple-shaped and inverted triangular women with thin hips and thin thighs. Pear-shaped and hourglass-shaped women and their offspring have higher cognitive ability, and the fat stored in buttocks and thighs contains omega-3 polyunsaturated fatty acids (DHA) which is indispensable for fetal brain development.
