Risk factors for osteoporosis in men aged 40 years or older: the results of the program «Osteoscreening-Russia»

Objective: to estimate the prevalence of individual risk factors (RFs) for osteoporosis (OP) and fractures, the frequency of high-risk osteoporotic fractures by the Fracture Risk Assessment Tool (FRAXR) and OP according to distal forearm X-ray densitometric findings in men aged 50 years or older in different regions of Russia.

Patients and methods. Random cluster proportionally stratified samples of men aged 40 years or older were formed in the district polyclinics of 23 towns of the country with over 100,000 people in the framework of the social program «Osteoscreening-Russia» (OSR). The survey was conducted using a unified questionnaire. Screening also involved a densitometric study of distal forearm bone mineral density using a peripheral X-ray osteodensitometer (Osteometer Meditech DTX-200). The final analysis included 5057 men from 14 towns of 5 federal districts (FDs) of Russia.

Results. Estimation of the prevalence of individual RFs for osteoporotic fractures in men aged 40 years or older showed that the most common RFs were insufficient dietary calcium intake (91%), smoking (30%), low-energy fractures in the history (20%), low physical activity (16%), and secondary causes of OP (11%). The men in the Ural FD (UFD), Siberian FD, and Central FD were more frequently found to have ≥3 RFs. 5% of men aged 50 years or older were at high risk for osteoporotic fractures by FRAXR, whereas the frequency of OP according to peripheral densitometric findings was 19%. The inhabitants of the North-Western FD and UFD had the greatest need for medical and preventive measures, which was identified by the FRAXR algorithm.

Conclusion. The OSR survey could reveal the most common clinical RFs for OP and osteoporotic fractures in men in 5 regions of the Russian Federation, insufficient dietary calcium intake and assess the risk of osteoporotic fractures and the rate of OP according to peripheral densitometric findings.
