Clinical features of osteoporosis among indigenous women of Russian and Buryat ethnicity in Trans-Baikal region

Abstract

Introduction Osteoporosis (OP) is a major social and medical problem for society.The aim of research was to identify risk factors for OP and the incidence of low-energy fractures in women with OP of Russian and Buryat ethnicity in Trans-Baikal region.Materials and methods We examined 98 women with OP (50 of Russian and 48 of Buryat nationality) and 100 women without objective signs of OP, comparable by age and nationality with the main group. All women underwent a questionnaire to identify risk factors for osteoporosis and osteoporotic fractures, determination of bone mineral density (BMD) using dual-energy X-ray absorptiometry, and determination of the absolute 10-year risk of major osteoporotic fractures using the online FRAX® calculator.Results The mean age of women with OP of Russian ethnicity was 65.5 [57.0;71.0] years, of Buryat nationality – 65.3 [56.0;69.0] years. Among risk factors in female members of Russian nationality, age older than 65 years, tendency to fall and decreased creatinine clearance were found more frequently. There was an inverse association between proximal femoral BMD and risk of falls (R = -0.31, p = 0.04) and a direct correlation between family history of ОP and spinal BMD (R = 0.65, p = 0.02).Discussion Age over 65 is a significant risk factor for osteoporosis and is included in the FRAX (Fracture Risk Assessment Tool) model. Reduces creatinine clearance and a tendency to fall have been associated with the development of OP and fractures in some studies. Our findings are consistent with previous studies.Conclusion Russian women were more likely than Buryat women to have risk factors for OP, such as falls and decreased creatinine clearance. Associations were found between proximal femoral BMD and falls, spinal BMD with a family history of OP and smoking among Russian women.
