title: The affecting factors of breast anthropometry in Korean women.
abstract: BACKGROUND
  Breast anthropometric morphology affects various factors with diverse physiognomy, making accurate measurements very difficult. The aim of this study was to measure the female breast using anthropometry and to use this method on normal subjects to examine breast asymmetry and consider the influence of age, height, weight, body mass index (BMI), parity, delivery mode, and breastfeeding in premenopausal Korean women.
  
  
  METHODS
  In total, 17 parameters of breast were measured with participants in a standing position. Breast volume was also assessed.
  
  
  RESULTS
  The mean values of the right and left breast volumes were calculated as 386.0±342.5 mL and 393.3±347.2 mL, respectively. With aging, the height of women decreased, but the weight, BMI, upper chest, middle chest, lower chest, waist, and hip widths, nipple-nipple length, and ptosis increased with statistical significance. No asymmetric differences were observed between each breast, except for nipple-inframammary fold length in 20-30-year-old women and upper arm length in 41-50-year-old women. In our study, the breast volume increased with age as a result of weight gain, but the delivery mode and breastfeeding did not affect anthropometric breast measurements.
  
  
  CONCLUSIONS
  In conclusion, age, weight, and BMI are important factors in determining breast anthropometry in our study. The results of the present study will help in the comparison of the anthropometric breast values of Korean women with those of women in other countries and may also be useful in the understanding of breast physiologic change-related obstetrical factors and epidemiologic factors.
