Examples of the effect of body size on BMD. *BMAD was calculated using the method of Kroger et al.14 BMAD Z scores were calculated as follows. Case 1: BMAD Z score = (0.234-0.314)/0.035 = -2.3, where the mean (SD) value for an 11 year old Caucasian female is 0.314 (0.035). Case 2: BMAD Z score = (0.300-0.320)/0.030 = -0.7, where the mean (SD) value for a 14 year old Asian boy is 0.320 (0.030). Reference population from the same geographical area as the subjects, and matched for age, gender, and ethnic group. Note that BMAD in boys lags behind that of girls during adolescence because of the later onset of puberty; thus the values for an 11 year old girl and 14 year old boy are very similar.
