OBJECTIVES:The current study aims to summarize breast anthropomorphic measurement features in Chinese patients with breast diseases and to investigate their potential correlations with demographic factors. MATERIALS AND METHODS:Fifteen breast anthropomorphic parameters of 605 Chinese female patients were collected prospectively. Breast ptosis status was scaled by two methods and breast volume was calculated according to a modified formula of BREAST-V. RESULTS:Among 1210 breasts, the average breast volume was 340.0±109.1 ml (91.8-919.2 ml). The distance from the nipple to the inframammary fold was 7.5±1.6 cm in the standing position. The width of the breast base was 14.3±1.4 cm (8.5-23.5 cm). The incidence of breast ptosis was 22.8% (274/1204), of which 37 (23.5%) and 79 (31.7%) women had severe ptosis assessed by different criteria. Increased height (OR[odds ratio] = 1.500, P<0.001), post-menopausal status (OR = 1.463, P = 0.02), increased BMI, breastfeeding for 7-12 months (OR = 1.882, P = 0.008) and more than one year (OR = 2.367, P = 0.001) were risk factors for an increased breast volume. Post-menopausal status (OR = 2.390, P<0.001 and OR = 2.621, P<0.001 for different scales), BMI≥24.7 kg/m2 (OR = 3.149, P<0.001 and OR = 2.495, P = 0.002), breastfeeding for 7-12 months (OR = 4.136, P = 0.004 and OR = 4.010, P = 0.002), and breastfeeding for more than one year (OR = 6.934, P<0.001 and OR = 6.707, P<0.001) were independent risk factors for breast ptosis. CONCLUSIONS:The current study provides anthropomorphic measurements data of Chinese women with breast diseases, which are useful for cosmetic and reconstructive breast surgery decisions. Post-menopausal status, increased BMI, and breastfeeding for more than six months were independent risk factors for both increased breast volume and breast ptosis.
