The aim of this study was to examine the prevalence of vitamin D deficiency in elderly patients with fragility fractures of the hip by estimating 25\u2010hydroxyvitamin D levels and to assess whether low vitamin D levels at the time of admission affect functional outcomes at 3\u2009months and mortality at 28\u2009days and 1\u2009year.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective study of all patients admitted with a fracture of the neck of the femur between January 2018 and March 2022. Data were obtained from the National Hip Fracture Database (NHFD) and Medway software. A total of 1440 patients were included. Patient demographics, including age, sex, fracture pattern, vitamin D levels at the time of admission, functional status at 120\u2009days, and mortality at 1\u2009month and 1\u2009year, were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average age of the patients was 81.91\u2009years (range 60\u2013108). Of the patients, 1009 (70%) were female and 431 (30%) were male. Vitamin D levels were low in 796 patients (55.3%). Mobility significantly declined in patients with vitamin D deficiency within 3\u2009months after surgery for proximal femur fractures. The 28\u2010day and one\u2010year mortality rates were 6.7% and 30.3%, respectively, in patients with low vitamin D levels, compared to 4.7% and 22.3% in those with normal levels. Patients with low vitamin D levels at the time of admission had higher mortality rates at both 28\u2009days and 1\u2009year compared to those with normal levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study demonstrates that low vitamin D levels at the time of admission for proximal femur fractures are associated
