Low serum levels of vitamin D significantly increase the risk of death in older adults with hip fractures: a prospective cohort.

Abstract

to evaluate the relationship between 25(OH)D3 levels and fatal outcome in patients over 60 years of age undergoing surgical repair of hip fractures. prospective cohort of patients undergoing surgical repair of hip fractures. At admission, 25(OH)D3 levels were measured, among other parameters. Patients were followed for at least 1 year, and incident mortality was recorded. 209 patients were included in the study, with a mean age of 79.5 ± 7.6 years among survivors and 80.7 ± 8.2 years among those who died in the first postoperative year (p=0.346). The 25(OH)D3 levels of survivors were significantly higher than those of patients who died (p=0.003). After adjusting for confounding variables, 25(OH)D3 levels below 12.5ng/mL were significant risk factors regardless of mortality (adjusted OR: 7.6; 95% CI: 2.35 to 24.56). our data show that serum 25(OH)D3 levels below 12.5ng/mL significantly and independently increased the risk of mortality in the first year after surgical repair of low-energy hip fracture in patients over 60 years of age in the geographic region where this study was conducted. Low albumin also showed a significant association with mortality in these patients. All other factors had no significant associations.
