.Summary This study was undertaken to assess the effect of blood glucose on BMD and interactions with age, sex, and BMI in a Taiwanese population. Both obese and non-obese people with type 2 diabetes (T2DM) had higher BMD, at lumbar spine and femoral neck, compared with healthy subjects. In addition, the prevalence of osteoporosis significantly decreased with blood sugar and HbA1c.
Purpose This study was undertaken to assess the effect of blood glucose on BMD and possible interactions with age, sex, and BMI in a Taiwanese population.
Patients and methods This study was a retrospective cross-sectional study using data from the Health Examination Database of Changhua Christian Hospital. Data on BMD of the lumbar spine and femoral neck were obtained by dual X-ray absorptiometry (DXA), and other relevant clinical and laboratory data were recorded.
Results The type 2 diabetes (T2DM) group had a higher BMD than the controls. When comparing the prevalence of osteoporosis between subjects by glucose and HbA1c level, the prevalence of osteoporosis significantly decreased with blood glucose and HbA1c. In addition, the BMD of the lumbar spine and femoral neck was higher in the T2DM group than in the controls. Osteoporosis was negatively associated with DM, BMI, and drinking, but positively associated with age, female gender, previous fracture history, and other diseases of the musculoskeletal system and connective tissue. The association between diabetes and osteoporosis remained statistically significant after adjusting for the above factors. T2DM was associated with lower odds of osteoporosis in both obese (OR = 0.77) and non-obese (OR = 0.63) (p for interaction = 0.555).
Conclusions Both obese and non-obese people with T2DM had higher BMD, at lumbar spine and femoral neck, compared with healthy subjects. In addition, the prevalence of osteoporosis significantly decreased with blood glucose and HbA1c.
