Abstract

Abstract: Objective: To assess bone mineral density (BMD) and associated clinical factors in patients with type 1 diabetes (T1D), latent autoimmune diabetes in adults (LADA), and type 2 diabetes (T2D) and in non‐diabetic subjects. Methods: Total 108 age‐, sex‐, disease duration‐, and postmenopausal ratio‐matched patients with T1D, LADA, and T2D each and 216 age‐, sex‐, and postmenopausal ratio‐matched non‐diabetic controls. Anthropometric, biochemical, and BMD data were collected and analysed. Results: BMD of total hip and lumbar spine of individuals in the LADA group was lower than those in the T2D and control groups but higher than those in the T1D group. After adjusting for body mass index (BMI), a significant difference in BMD in the lumbar spine was seen between groups. After adjustment for smoking, BMI, 25‐(OH) vitamin D, calcium, haemoglobin A1c, and diabetic complication scores, BMD values of patients in LADA group were not significantly different from those of patients in T1D and T2D groups. Multiple stepwise regression analysis showed that BMD was (a) positively associated with weight and C‐peptide, and negatively associated with age in patients with diabetes, (b) positively associated with C‐peptide in the T1D and LADA groups. The proportion of patients with osteoporosis in the T1D, LADA, T2D, and control groups was 55.6%, 45.4%, 34.3%, and 26.9%, respectively. Conclusions: BMD values in T1D, LADA, and T2D were in an increasing order of mention. Patients with autoimmune diabetes were more susceptible to osteoporosis. A lower C‐peptide level may be responsible for decreased BMD in individuals with autoimmune diabetes.
