The Influence of Nutritional Risk in Elderly Patients Hospitalized for Bone Fracture
Keywords:Nutritional Risk, Hip Fracture, Cognitive Plasticity, Old Age.
Introduction: Bone fractures in older adults involve hospitalizationÂ and surgical intervention, aspects that have been related toÂ functional and cognitive impairment. Several variables have beenÂ studied as moderators in how these patients evolve, such as nutritionalÂ status. However the implications of nutritional status inÂ the subsequent evolution of the hospitalized elderly, has not beenÂ studied to date.
Objective: In the present study the authors analyze the relationshipÂ between the nutritional status, and diferent variables related to theÂ evolution of older adults who have undergone surgery after a bone fracture.
Method and instruments: One hundred-seventy six elderly (agedÂ 65-105 years; 138 females and 38 males) participated in the study.Â Participantsâ€™ consent was obtained according to the Declaration ofÂ Helsinki. The following questionnaires were administered: Phototest,Â Auditory Verbal Learning Test of Learning Potential (AVLT-PA) andÂ Mini Nutritional Assessment (MNA). The questionnaires was administeredÂ at the three months of the hospitalization.
Results: The elders`s nutritional state showed a significant relationshipÂ with cognitive decline (r=.171, p=.038), and with cognitive plasticityÂ (r=.238, p<.010). Furthermore, those elderly patients at risk ofÂ malnutrition have a higher cognitive decline at the three months ofÂ the hospitalization (t= -3.808, p=.000) and worse cognitive plasticityÂ (t= -3.096, p=.004
