Top panel, Annual rate of change in BMD of the lumbar spine in premenopausal (red bars), early perimenopausal (blue bars), late perimenopausal (yellow bars), and postmenopausal (green bars) African-American (n = 494), Caucasian (n = 944), Chinese (n = 221), and Japanese (n = 243) women from the full cohort. Rates of change were estimated from multivariable linear mixed models and adjusted for multiple covariates. Error bars represent 95% confidence limits. Comparisons were made between ethnic groups (P values for lumbar spine in pre-, early peri-, late peri-, and postmenopausal women, respectively): African-American vs. Caucasian, 0.65, 0.11, 0.10, and <0.001; African-American vs. Chinese, 0.031, <0.001, 0.006, and <0.001; African-American vs. Japanese, 0.87, <0.001, <0.001, and <0.001; Caucasian vs. Chinese, 0.004, 0.014, 0.06, and 0.003; Caucasian vs. Japanese, 0.58, <0.001, 0.009, and <0.001; Chinese vs. Japanese, 0.09, 0.43, 0.81, and 0.51. Bottom panel, Annual rate of change in BMD of the lumbar spine in premenopausal (red bars), early perimenopausal (blue bars), late perimenopausal (yellow bars), and postmenopausal (green bars) African-American (n = 198), Caucasian (n = 587), Chinese (n = 167), and Japanese (n = 181) women weighing between 50 and 78 kg. Rates of change were estimated from multivariable linear mixed models and adjusted for multiple covariates. Error bars represent 95% confidence limits. Comparisons were made between ethnic groups, with P values for lumbar spine in pre-, early peri-, late peri-, and postmenopausal women, respectively, as follows: African-American vs. Caucasian, 0.13, 0.24, 0.43, and 0.07; African-American vs. Chinese, 0.80, 0.007, 0.56, and 0.31; African-American vs. Japanese, 0.10, 0.010, 0.24, and 0.02; Caucasian vs. Chinese, 0.22, 0.041, 0.18, and 0.52; Caucasian vs. Japanese, 0.59, 0.06, 0.52, and 0.34; Chinese vs. Japanese, 0.16, 0.87, 0.11, and 0.17.
