The Association of nutritional status and physical activity on osteoporotic refractures among older adults

Abstract

BackgroundThis paper focuses on revealing the relationship between the Geriatric Nutritional Risk Index (GNRI) and Activity of Daily Living (ADL) with osteoporotic refracture. MethodsData from 1068 inpatients with osteoporotic fractures were analyzed. Binary logistic regression, Cox proportional hazard regression and Kaplan-Meier curves were performed for osteoporosis characteristics and its risk factors. Receiver operating characteristic (ROC) curve was developed to predict the cut-off value. ResultsThe study showed that older age, lower ADL and lower GNRI were independent risk factors for osteoporotic fracture with OR of 1.039, 0.946, 0.892 and HR of 1.033, 0.967, 0.947 respectively. According to the results of ROC, the predictive accuracy of GNRI was high with an area under ROC (AUC) of 0.715, sensitivity of 76.6%, specificity of 53.5% and a threshold value of 99.65. ConclusionOlder age, lower ADL and lower GNRI were independent risk factors for osteoporotic refracture.
