Abstract:
Objective To investigate the relationship between lean mass and bone mineral content (BMC)and bone mineral density(BMD)in normal and increased BMI overweight and obese patients with type 2 diabetes mellitus.Methods Seventy-two patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Nantong from June 2014 to August 2016 were selected in this study.According to body mass index (BMI),the patients were divided into the normal group(BMI<24 kg/m2)and the obese diabetic group(BMI=24 kg/m2).The systolic blood pressure(SBP),diastolic blood pressure(DBP),body mass index(BMI),waist circumference(WC),fasting blood glucose(FBG),glycosylated haemoglobin(HbA1c),blood lipids(TC,TG, HDL-C,LDL-C),alanine aminotransferase(ALT),creatinine(Cre),calcium(Ca),phosphorus(P)and serum 25 hydroxyvitamin D(25OHD)were measured.The bone mineral density(BMD),bone mineral content (BMC),body fat percentage(BF%),lean body mass(LBM),fat mass(FM),and the ratio of male fat to female fat(A/G)were measured by dual energy X-ray(DXA).The above indicators were statistically analyzed.Results 25OHD in the obese diabetic group was(17.1+ 12.6)μg/L,lower than that in the normal diabetic group((23.8±8.2)μg/L)(P<0.05),but BMI,WC,BMD,BMC,%BF,FM in the obese diabetic group(BMI:(27.8±2.1)kg/m2,WC:(96.8±7.9)cm,BMD:(1.12±0.14)g/cm2,BMC:(2.47±0.38) kg,fat and fat percentage:(1.18±0.23))were higher than those in the normal group(BMI:(22.3±1.7)kg/m2,WC:(84.5 + 7.9)cm,BMD:(0.93 ± 0.13)g/cm2,BMC:(2.02 ± 0.28)kg,fat and fat percentage:(2.02±0.28))(P<0.05).There was a significant positive correlation between LBM and BMC in different parts of the body(R=0.37,0.37,0.35,0.43,P<0.05,P<0.001).The ratio of BMI and A/G was also positively correlated with BMC and BMD(r=0.38,0.31,0.28,0.33,0.27,0.25,0.23,0.37,P<0.05,P<0.001).There was a negative correlation between body fat percentage and BMC,BMD(r=-0.30,-0.27,-0.25,-0.33,P<0.05,P<0.001).After correction of age,sex,BMI and 25OHD,multiple linear regression analysis was used to indicate that LBM was a strong predictor of BMC(regression coefficient=0.210,P=0.001).Conclusion In patients with type 2 diabetes mellitus,BMC and BMD increased significantly in patients with elevated BMC,and lean body weight was a strong influencing factor for BMI.
