About this study
Official title: Study of the Adequacy Between Calcium Supplementation and Dietary Intake in Treatment-naive Patients After Fracture With a Fracture Suspected of Being Due to Bone Insufficiency, Consulting a Rheumatologist for the First Time in at Least 5 Years.
Osteoporosis is a disease that causes many fractures. However, treatments exist such as anti-osteoporotic treatments, vitamin D supplementation and an adaptation of calcium intake. 80% of patients with an indication for anti-osteoporotic treatment are never treated with these anti-osteoporotic treatments after a first fracture. On the other hand, more than 84% of them are supplemented with calcium and vitamin D. It often appears in the practice of rheumatologists that some patients are supplemented while their dietary intake is sufficient, and vice versa. The objective of the study is therefore to take stock of the (in)adequacy between the dietary intake of patients and the supplementation prescribed to them following an osteoporotic-like fracture.
