Relationship between Bone Mass (BMC and BMD) and Obesity in Chinese Hans / 中国康复理论与实践

ABSTRACT

@#Objective To investigate the relationship between bone mass(bone mass content,BMC;bone mass density,BMD) and waistline(WL) related obesity in Chinese Hans lives in Jinan.Methods 265 consecutively healthy volunteers were recruited in Jinan.BMC and BMD of all subjects were measured with dual energy X-ray absorptiometry.Obesity was defined as a WL ≥85 cm in men or ≥80 cm in women.Analysis of covariance(ACNOVA) and partial correlation were used.Results Partial analysis showed that there is a linearity positive correlation between bone mass and WL.After controlling for gender and age,correlation coefficients of WL with BMD in all over the body,extremities inferior,pars trunk,cervical rib,basin and backbone of Pearson were 0.296,0.306,0.340,0.368,0.381 and 0.260(P=0.000).Correlation coefficients of WL with BMC in all over the body,extremities inferior,pars trunk,cervical rib,basin and backbone were 0.337,0.391,0.327,0.358,0.302 and 0.269(P=0.000).ACNOVA showed that there is a significant difference of bone mass between obesity and non-obesity subjects after adjusted for age and gender.Conclusion There is a positive correlation between obesity and bone mass in Chinese Hans.
