Abstract

Background: Our aim is to identify the relation of leptin, adiponectin and insulin resistance to bone mineral density (BMD) in type 2 diabetic postmenopausal women and compare it with that experienced by nondiabetics.
Material and methods: Seventy six postmenopausal female patients were included in the study. Postmenopausal type 2 diabetic (n = 19) and nondiabetic patients (n = 19) with spine and/or hip BMD T score lower than -2 were included in the study, and postmenopausal type 2 diabetic (n = 20) and nondiabetic women (n = 18) with normal BMD (T score > –1) were selected as control groups. Those receiving therapy for osteoporosis, over the age of 65, those who had a disease and were taking a medication that could affect bone metabolism were excluded. Biochemical tests, as well as leptin, adiponectin and insulin levels, were measured and insulin resistance was calculated using the HOMA test.
Results: There was no correlation between low BMD and leptin, adiponectin and insulin resistance. There was only a negative correlation between leptin and femur Ward’s triangle BMD.
Conclusion: Further large-scale studies must to be performed in order to analyse the effects of leptin, adiponectin and insulin resistance on bone metabolism in type 2 diabetic patients. (Pol J Endocrinol 2011; 62 (5): 429–435)
