Men with hip fractures have poorer nutritional status and survival than women

Abstract

Background Many hip fracture patients have a poor nutritional status which may be one explanation for their increased mortality.Patients and methods We studied nutritional status and other mortality-related factors prospectively in 165 patients with hip fractures (85 women). We concentrated on differences between death rates and survival rates at 3 months and at 1 year, and between those patients who died within 3 months and those who died later.Results In general, men had a poorer nutritional status and a larger number of comorbidities. Also, there were more smokers and alcohol abusers amongst the men. Of the patients who died during the first 3 months, most were men, and their initial nutritional status was poorer than that of women. Multivariate logistic regression analysis revealed a correlation between mortality and total serum protein, retinol binding protein and the number of comorbidities. Among patients who died after 3 months, mortality was associated with the number of comorbidities and smoking.Interpretation The higher mortality rate in men than in women after hip fracture may in part be explained by the poor nutritional status in men.
