Abstract:
Objective To explore the change of 25 hydroxyvitamin D level and its correlation with glucose metabolism and bone mineral density in elderly men with type 2 diabetes mellitus(T2DM).Methods Hospitalized 53 elderly male patients with T2DM (T2DM group) and 51 patients without T2DM (NDM group) were chosen.Blood.biochemical indexes and 25 hydroxyvitamin D level were measured.Bone mineral density of lumbar (L2_4),left proximal femur was measured by dual energy X-ray.Results The serum 25 hydroxyvitamin D level in T2DM group was lower than that in NDM group [(12.38 ±5.12)μg/L vs.(17.35 ± 5.52) μ g/L],and there was significant difference(P＜ 0.05).The serum 25 hydroxyvitamin D level was negatively associated with fasting blood glucose level and glycosylated hemoglobin (r =-0.225,-0.499,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with fasting insulin and homeostasis model insulin resistance index (r =-0.050,-0.082,P ＞ 0.05).The incidence of osteoporosis in T2DM group was higher than that in NDM group [30.19％(16/53) vs.11.76％(6/51)],and there was significant difference (P ＜0.05).The serum 25 hydroxyvitamin D level was positively associated with bone mineral density of femur neck,greater trochanter of femur and Ward triangle(r =0.773,0.762,0.812,P ＜ 0.05).The serum 25 hydroxyvitamin D level was not associated with bone mineral density of lumbar (L2_4)(r =0.116,P ＞ 0.05).Conclusions The prevalence of vitamin D deficiency is found in elderly men with T2DM.Vitamin D level can affect blood glucose control and increase the risk of the occurrence of osteoporosis.Therefore,T2DM patients,especially elderly patients,should be routine vitamin D testing.Vitamin D supplementation to the patients of vitamin D insufficiency in time may be beneficial to glucose metabohsm and the prevention and treatment of osteoporosis.
