“…As expected, the group of postmenopausal women diagnosed with osteoporosis had a significantly higher mean age than the osteopenic or unaltered group, corroborating with results presented by other studies, since the advance in age is inversely associated with BMD (26)(27)(28) . Regarding the anthropometric variables that characterize the sample, it was observed that women with no alteration in BMD presented significantly greater height than osteoporotic women, however, with no differences for body weight or BMI.…”

Background: Postmenopausal women typically present loss of bone mineral density (BMD), muscular strength, and postural balance. However, there is no consensus in the literature on the correlation between these variables. Objectives: Our objective was to verify the correlation between BMD, isokinetic peak torque of knee extensors and flexors, and static postural balance in postmenopausal women. Methods: Fifty-one postmenopausal women underwent BMD evaluation through dual-energy X-ray absorptiometry (DXA) for four bone regions (lumbar spine, femoral neck, total hip, and trochanter). Muscular strength of knee extensors and flexors was evaluated in an isokinetic dynamometer at 60 and 180 degrees per second in the dominant lower limb. Static postural balance was evaluated on a force platform during five different tasks (bipodal eyes open, bipodal eyes closed, semi-tandem eyes open, semi-tandem eyes closed, and unipodal). Statistical analysis involved Spearman's correlation coefficient (rho). Results: There was no significant correlation between BMD and isokinetic peak torque of knee extensors and flexors. Approximately half (27 of 60) of the postural balance variables presented significant inverse correlations (p < 0.05) with BMD and of these, the majority (22 of 27) presented moderate correlation (rho between -0.49 and -0.30). Most correlations were for bipodal support tasks with eyes open and eyes closed. Conclusion: Greater postural oscillation in different balance tasks was correlated with lower BMD in postmenopausal women. Therefore, it is suggested that intervention protocols for women with impaired BMD, especially osteoporotic, consider balance training as part of rehabilitation.

“…In fact, most studies compare the differences between women and men without providing gender-related reference curves. (12)(13)(14)(15)(16)(17) In addition, in contrast to a recently study analyzing a Chinese female population, (23) our curves were determined considering the effects of weight and height because these parameters have important effects on structure and bone mass.…”

“…Thereby suggesting that the bone loss density and the microarchitecture deterioration may be similar in individuals from different ethnicities. (23) This study established a set of reference data for volumetric and structural bone parameters obtained by HR-pQCT and biochemical properties by finite element analysis, according age, weight and height based on a miscegenated normal population. These results may be useful in clinical practice for interpreting fracture risk.…”

Chinese Women in Both the United States and Hong Kong Have Cortical Microstructural Advantages and More Trabecular Plates Compared With White Women

We cross‐sectionally compared racial differences in bone quality between Chinese women in the United States (US) and Hong Kong (HK) with white women. A total of 514 women were included. We measured bone geometry, mass, microstructure, and stiffness by high‐resolution peripheral quantitative computed tomography (HR‐pQCT), individual trabecula segmentation (ITS), and microfinite element analysis (μFEA). After adjustment for age and body mass index (BMI), premenopausal Chinese women in the US and HK had smaller bone area but greater radial cortical (Ct.) thickness and Ct. and trabecular (Tb.) volumetric bone mineral density (vBMD) versus white women but did not differ from each other. At the radius, Tb. number was lower and spacing greater in Chinese women from HK and the US versus white women, whereas Chinese women did not differ from each other. Tb. thickness was highest in Chinese women from HK, intermediate in Chinese‐Americans, and lowest in white women. Chinese women had more trabecular plates versus white women, leading to greater age‐ and BMI‐adjusted stiffness for premenopausal Chinese women in HK and the US (both p < 0.05) versus white women. Tibial differences were similar in premenopausal women; analogous trends in microstructure were present in postmenopausal women at the tibia, although stiffness did not differ. In contrast, at the radius, cortical, plate‐to‐rod ratio, and stiffness were similar between postmenopausal HK and white women. Adjusting for age, weight, and height rather than age and BMI tended to reduce differences in bone size and Tb. parameters but accentuate cortical differences such that Chinese premenopausal women in both locations and postmenopausal women from HK had higher stiffness at both skeletal sites compared with white women. Compared with white women, Chinese women in the US and HK have vBMD and microstructural advantages leading to higher or similar mechanical competence in pre‐ and postmenopausal women, respectively, despite smaller bone size. © 2018 American Society for Bone and Mineral Research.
