The purpose was to report on the burden of osteoporotic fractures in the Eastern Mediterranean Region (EMR) and the use of bone mineral density (BMD) dual-energy X-ray absorptiometry (DXA) databases for osteoporosis diagnosis. PubMed electronic database was reviewed using the following MeSH terms: Hip fractures, Fractures, Compression, Radius Fractures, Osteoporosis, Bone density, and Middle East up to July 2009. Incidence of hip fractures varied across the EMR between 100 and 295 per 100,000 person-years in women and 71 and 200 per 100,000 person-years in men. No data were found on other nonvertebral osteoporotic fractures. Prevalence of radiographic vertebral fractures older than 65 yr ranged between 15% and 25% in women and 7.3% and 18% in men. By 2020, the number of hip fractures older than 50 yr would increase by 20%. DXA manufacturer's reference curves for the spine were higher than population-specific ones. At the hip, National Health and Nutrition Examination Survey (NHANES) and population-based curves were comparable. Estimates of the relative risk of vertebral fracture per SD decrease in BMD using NHANES and local data set were similar, that is, 1.61(1.17-2.23) and 1.49 (1.14-1.95), respectively. The EMR is similar to southern Europe regarding incidence rates of hip fracture, suggesting the health burden to be significant. Using DXA at the hip, population-specific reference databases did not perform better than NHANES on which the FRAX model has been developed highlighting the need for reviewing fracture risk assessment strategies in the EMR.
