    To determine the relationship between risk factors and use of DXA scans. Our study showed a relatively high use of DXA in low-risk women and the relatively low coverage in women with multiple risk factors. Moreover, distance to DXA clinics, age, and socio-economic factors are associated with the use of DXA. Introduction: To determine the relationship between risk factors for fracture and use of DXA scans in Danish women in relation to distance to DXA clinics and socio-economic factors. Methods: From the Danish National Civil Register we randomly selected 5,000 women aged 40-90 years living in the region of Southern Denmark to receive a mailed questionnaire concerning risk factors for fractures. Results: The respondents rate was 84% and 77% of the invited population were available for analysis. A total of 10.3% of the women without risk factors and only 36% of the women with three or more risk factors had a history of DXA. The likelihood of a history of DXA was higher with increasing FRAX(™) 10-year risk; i.e., 8.7% and 30.2% in patients with a 10-year fracture risk of 0-14.9% and 25-100%, respectively. In women with less than 10 km to nearest DXA facility, 20.2% had a history of DXA, while 11.5% of those with more than 40 km to the nearest scanner had a history of DXA. Logistic regression analysis showed that distance, fracture risk, oral glucocorticoids, low-energy fracture, conditions associated with secondary osteoporosis, low BMI, history of falls, age 65-79 years, spouse status, and income were significantly associated with having a history of DXA. Conclusions: Our study showed a relatively high use of DXA in low-risk women and the relatively low coverage in women with multiple risk factors. Moreover, distance to DXA clinics, age, and a number of socio-economic factors are associated with the use of DXA.
