Bone density (BMD bone mineral density)... On average nogs are above average... True story https://pic8.co/sh/TaDdtH.jpeg https://archive.is/ipxks#selection-3035.0-3085.198 >>A WHO Scientific Group Technical Report noted highly significant differences in BMD in different regions of the world that varied by approximately 1 sd value (33). Variation in BMD between populations is substantially less, therefore, than the variation in fracture risk noted earlier. Certain ethnic patterns in BMD can be inferred from NHANES: non-Hispanic Blacks have greater femoral neck and lumbar spine BMD than Mexican-American or non-Hispanic Whites across the age spectrum (20, 24, 34). The 95% confidence intervals for mean femoral neck BMD in non-Hispanic Blacks do not overlap the confidence intervals for Mexican-Americans or non-Hispanic Whites (Fig. 1) (20, 35). However, the 95% confidence interval (±2 sd) for non-Hispanic Whites completely encloses the means for non-Hispanic Blacks and Mexican-Americans. The implication is that within-group BMD variation is much larger than between-group variation.
