How much do patients know about osteoporosis? A survey among patients referred to the dual-energy X-ray absorptiometry exam

Background: Inadequate osteoporosis education can make patients ill-informed concerning preventive and therapeutic interventions and creates misconceptions and unnecessary concerns about the disease. Aim: Our study aimed to assess whether patients referred to the DXA exam by their general practitioner are informed about risk factors for osteoporosis, comparing patients who received a diagnosis of osteoporosis before the exam with those without this diagnosis. Methods: An observational single-center study was performed among patients who were referred to the DXA exam at the Osteoporosis Service of Marche Nord Hospital (Fano, Italy) between April and July 2019. Socio-demographic and clinical characteristics, awareness of suffering from osteoporosis, femoral and lumbar spine T-score and bone mineral density, risk of fracture and the I-FOOQ score were assessed. Results: A pilot study was carried out to validate the questionnaire in the Italian language (alpha-Cronbach 0.75). After that, a sample of 128 patients was enrolled (response rate 93.3%). Mean age was 66 ± 10.6 years, 95.6% were women. Overall, I-FOOQ mean score was 12 ± 3.5. Age, educational level, menopausal age, body mass index, femoral T-score were not associated with a better knowledge (p > 0.05). A comparison between who know to suffer from osteoporosis and others found no differences (12.2 ± 3.4 and 12 ± 3.5, respectively, p = 0.772). Effect of walking, recommended calcium intake, and familiar predisposition are the less known topics. Conclusion: Patients who undergo the DXA exam are poorly informed about risk factors for osteoporosis, independently of age, education, bone mineral density and risk of fracture. Knowing to suffer from osteoporosis does not increase the likelihood to be informed. It is mandatory to improve the education that is provided to the patients, as there are effective non-pharmacological interventions to prevent and treat osteoporosis.
