A multicenter, case control study of risk factors for low tibial speed of sound among residents of urban areas in Turkey.
Risk factors which have been associated with low bone mass are multifactorial and represent regional differences between and within countries. The purpose of this study was to evaluate the possible risk factors of low tibial speed of sound (tSOS), which determines cortical bone status among residents of urban regions in Ankara, Izmir, and Istanbul, in Turkey, and also to compare groups of different socioeconomic status (SES). A total of 1,026 subjects (63% women and 53% of low socioeconomic status) 40-70 years old were included in the study. Risk factors of osteoporosis were determined using the European Vertebral Osteoporosis Study (EVOS) questionnaire, and the bone status was screened by tSOS. Socioeconomic status was found to be among the major risk factors of low tSOS in our population (odds ratio 0.39, 95% confidence interval 0.26-0.58), besides the well-known risk factors such as age and gender. Therefore, we suggest that SES is an important determinant of cortical bone status. Additionally, our results confirmed the correlation between tSOS and the clinical determinants of bone mass.
