From: Breast composition during and after puberty: the Chilean Growth and Obesity Cohort Study
Description of breast composition and BMI z score in girls at different maturation ages. The Growth and Obesity Cohort Study (n=1,442 breast DXA scans). The figure represents the mean and standard deviation of breast composition components (%FGV, AFGV, and BV) and BMI at different time points of maturation: Tanner stage breast (B) B1, B2, B3, B4 before menarche onset, B4 after menarche onset, B5 before menarche onset, B5 after menarche onset, 1, 2 and 4 years after menarche onset. BV: breast volume; AFGV: absolute fibroglandular volume; %FGV: % of fibroglandular volume; BMI z-score: body mass index z-scores according to World Health Organization data 2007
