Abstract:
BACKGROUND: Basal metabolic rate (BMR) is an important indicator of human energy metabolism, and low BMR leads to the dysfunction of liver and kidney. Low BMR is usually found in patients with hip fractures, but there is a lack of study on the relationship between mortality of hip fracture and low BMR. OBJECTIVE: To investigate the effect of low BMR on the 1-year mortality in older adults with hip fractures. METHODS: Totally 507 patients with hip fractures aged more than 60 years from January 2014 to March 2016 were included in this retrospective study. Age, sex, surgery or not, surgical pathway, duration from injury to surgery, hospitalized pulmonary infection, number and kind of comorbidities, and 1-year mortality were recorded. BMR on admission was recorded, and multiple Logistic regression analysis was applied. RESULTS AND CONCLUSION: All patients were followed up for 13-15 months, and the 1-year mortality was 13.41% (68/507). The mortality in the low BMR group was significantly higher than that in the non-low BMR group (P ＜ 0.05). Logistic regression analysis showed that older age, conventional treatment, number of combined medical diseases, hospitalized pulmonary infection, and low BMR are risk factors for 1-year mortality in older adults with hip fracture. These results imply that low BMR is strongly associated with 1-year mortality in older adults with hip fracture. BMR can reflect the nutritional status, neuroendocrine, cellular and energy metabolism. Thereafter, for older adults with hip fractures and low BMI, nutrition therapy, re-warming, and endocrine therapy may help reduce the trauma-induced mortality.
