Objective To research the changes of calcium regulation hormone and bone mineral density (BMD) in type 2 diabetes mellitus (T2DM ) patients and analyze the main impact factors. Methods 117 T2DM patients (T2DM group ,M/F=52/65 ,age 40~79 years) and 63 age‐ and gender‐matched healthy people (NC group) were selected in this study. According to the course of diabetes ,blood glucose control and the value of BMD ,T2DM patients were divided into subgroups :course≤10 years ,and>10 years ;HbA1 c≤8% ,and>8% ;normal BMD ,osteopenia ,and osteoporosis (OP). Serum 25‐hydroxy vitamin D3 [25(OH)D3 ]and Parathormone (PTH) were measured and BMDs of lumbar spine (L1 ~L4 ) , femoral neck ,total hip ,and whole body were evaluated for all the subjects. Result (1)Compared with NC group ,the level of serum 25(OH)D3 and BMDs of femoral neck and total hip decreased significantly in T2DM group[ (35.57 ± 12.30)nmol/L ,(0.848 ± 0.136)g/cm2 ,(0.873 ± 0.150)g/cm2 vs(44.94 ± 17.40) nmol/L ,(0.927 ± 0.173)g/cm2 ,(0.934 ± 0.140)g/cm2 ,respectively ,P<0.01 or P<0.05)]. The level of PTH increased in T2DM group[ (8.50 ± 4.15) vs(5.62 ± 3.93)pmol/L ,P<0.01]. (2)Compared with the group duration of diabetes≤10 years ,BMD of femoral neck and total hip decreased in patients with duration of diabetes>10 years[ (0.814 ± 0.148) ,(0.840 ± 0.157) vs (0.882 ± 0.111) ,(0.908 ± 0.139) g/cm2 ,respectively ,P<0.05]. The level of PTH increased [(10.55 ± 9.09) vs (7.06 ± 3.74)pmol/L , P<0.05)]. 25(OH)D3 and total body BMD have no significant difference(P>0.05). (3)Compared with HbA1c≤8% group ,BMD of femoral neck and total hip in HbA1c> 8% group decreased [(0.830 ± 0.131) ,(0.832 ± 0.161) vs (0.891 ± 0.130) ,(0.949 ± 0.130)g/cm2 ,respectively ,P<0.05]. The level of PTH increased [(9.96±8.80) vs (7.21±3.98)pmol/L ,P<0.05]. 25(OH)D3and total body BMD have no significant difference(P> 0.05). (4)The rates of OP and osteopenia (41.03% ,47.86% ) in T2DM were higher than those in NC group (26.98% ,33.33% ) (χ2 =4.367 ,4.669 ,P<0.05). The duration of diabetes and the levels of HbA1c and PTH were longer or higher in OP group than those with normal BMD or osteopenia (P<0.05). (5)Logistic regression analysis showed that BMD negatively correlated with the duration of diabetes ,HbA1c ,and PTH (β= 0.076 ,0.213 ,0.112 ,respectively ,P< 0.05) ,and positively correlated with 25(OH)D3 (β= -0.043 ,P<0.05). Conclusion The values of BMD decreased and the incidence of OP is higher in T2DM patients ,particularly in patients with longer diabetic duration and poor glycemic control.
