Osteoporosis is a condition that describes compromised skeletal microarchitecture in general, with clinical signs of decreased bone mineral density. Ankylosing spondylitis patients are at increased risk for developing osteoporosis. Identifying whether multiple sclerosis patients have information and awareness about this disease is crucial. This study is aimed to investigate awareness and knowledge of osteoporosis in ankylosing spondylitis patients.

Osteoporosis is a common disease of bone loss. The reduced bone strength predisposes an increased risk for fractures in older individuals. It can affect people from different ethnicity. Many factors increase the risk of osteoporosis, including age, postmenopausal state, glucocorticoid use, low body weight, calcium, vitamin D, immobility, and chronic inflammation. Patients with ankylosing spondylitis are at high risk of developing osteoporosis due to chronic inflammation and their medications. Patients' knowledge and awareness about osteoporosis are essential for early detection, implementation of lifestyle changes, and treatment compliance. This study aimed to investigate osteoporosis awareness and knowledge about osteoporosis in patients with ankylosing spondylitis.
