There is a difference of bone tissue state of women belonging to various ethnic groups. We have conducted a study of bone tissue state among postmenopausal women of Buryat origin. Buryats are a main northern group of Mongolians, they are a core population of Siberia with a compact residence close to Lake Baikal. We have examined the associations between bone mineral density (BMD), trabecular bone score (TBS) and bone biomarkers in 17 postmenopausal women with T2D (59 years, diabetes duration 5.2 years, A1c <8.0%) and 21 postmenopausal women without diabetes (56 years). Collagen type 1 cross-linked C-telopeptide (CTX), 25-hydroxyvitamin D, ionized calcium (iCa), femoral neck BMD were similar between two groups. T2D postmenopausal women had lower osteocalcin (OC), procollagen type 1 N propeptide (P1NP), TBS and higher BMD total hip, BMD lumbar spine 1-4 (L1-L4) compared to the controls (Table). Total hip BMD in women with T2D was associated with body mass index (BMI). TBS was positively correlated with iCa. Twenty-five-hydroxyvitamin D was associated with lower OC, P1NP and CTX. Total hip BMD and BMD L1-L4 were positively correlated with BMI in women without diabetes. Femoral neck BMD was positively correlated with P1NP and inversely correlated with women’s age. T2D in Buryat women is associated with low levels of osteosynthesis markers, TBS and higher BMD. TBS was positively correlated only with iCa.
