Risk Factors, Manifestation, and Awareness of Osteoporosis among Patients of Various Specialists in Switzerland: Results of a National Survey

Osteoporosis is the most common chronic metabolic bone disease, known to be underdiagnosed and undertreated in parts of the Swiss population. Due to expected rise in new fragility fractures, adequate awareness of associated risk factors and diagnostic and therapeutic options will be essential for the management of osteoporosis. We therefore explored these aspects in a nationwide survey of Swiss specialists and their patients. A total of 262 physician questionnaires and 9065 patient questionnaires were analyzed, mainly from general practitioners (64.9%), followed by rheumatologists (16.8%), gynecologists (12.2%), and endocrinologists (6.1%). Around 20% of patients were under medication and/or had a medical condition increasing the risk of osteoporosis. Further risk factors, such as low consumption of calcium-rich foods, smoking, elevated alcohol intake, and insufficient physical activity, were present across regions and medical fields. 53.9% of patients did not take calcium/vitamin D supplements; 3.5% reported having fragility fractures, and 7.3% received treatment for osteoporosis. Only 38.5% of surveyed patients knew of the chronic nature of osteoporosis, indicating rather low awareness in this population. Despite generally perceived relevance of osteoporosis for daily practice, aspects of its prevention and management varied across regions and medical fields. Raising awareness among patients and physicians will be vital for addressing osteoporosis on a national scale.
