[Breast volume measurement in 125 Chinese young women]

The author carried out measurement of breast volume and the body surface anatomy in 125 unmarried young women. Through the measurement and analysis, the author came to the following conclusions: 1. The characteristics of body build of Chinese young women are: a. The mean height: 159.00 cm-160.00 cm; The mean weight: 50.40 kg-60.00 kg; The standard weight: height minus 110. b. The mean chest circumference difference, 2.0 cm. c. The mean distance from nipple to the supra-sternal notch is 19.05 cm, that of between nipples 20.0 cm, forming a equilateral triangle. d. The average breast volume, 310-330 ml; The standard breast volume, 250-350 ml; if the body weight is over the standard, the breast volume increases by 20 ml every 1.0 kg in body weight. e. The standard breast forward projection: 3.0 cm-4.0 cm. 2. Variables of the breast volume are: a. The breast volume is positively correlated with weight, chest circumference, waist circumference and buttock circumference, but negatively with height. b. The breast volume is closely related to difference between the chest circumference across the nipple and that across the horizontal line just under the armpits. The correlative equation can be approximately represented as V = 250 + 50 x D + 20 x OW (D = difference OW = overweight). c. The nipple position is not dependent on the height, but varies with the breast volume, that is, the nipple position lowers 1.0 cm with every increase of 300 ml in the breast volume. 3. The breast volume calculating table is derived from the radius and forward projection of breasts.(ABSTRACT TRUNCATED AT 250 WORDS)
