ObjectiveTo explore the influencing factors for occurrence of exercise fear in patients with chronic renal failure receiving maintenance hemodialysis (MHD), and to establish a nomogram risk prediction model. MethodsA total of 296 MHD patients with chronic renal failure were selected for investigation by employing the convenience sampling method, and they were divided into modeling group (207 cases) or validation group (89 cases) according to investigation time. The risk factors for occurrence of exercise fear in the modeling group were analyzed, the nomogram risk prediction model was drawn, and this model was validated by using the data from the validation group. ResultsAge≥60 years old, body mass index≥24 kg/m2, dialysis age≥3 years, categories of complications≥2, a low perceived exercise benefits scale score, a high perceived dyskinesia scale score, and a low Chinese Post-Traumatic Growth Inventory (C-PTGI) score were the risk factors for occurrence of exercise fear in MHD patients with chronic renal failure (P＜0.05). The nomogram risk prediction model established based on aforementioned risk factors exerted favorable discrimination, predictive accuracy, and relatively high net benefit value.ConclusionAge≥60 years old, body mass index≥24 kg/m2, dialysis age≥3 years, categories of complications≥2, a low perceived exercise benefits scale score, a high perceived dyskinesia scale score, and a low C-PTGI score are the risk factors contributed to occurrence of exercise fear in MHD patients with chronic renal failure, and the nomogram risk prediction model established based on risk factors as above exerts favorable discrimination, predictive accuracy, and relatively high net benefit value. Clinically, the occurrence risk of exercise fear can be identified early and accurately according to the situation of MHD patients with chronic renal failure, and relevant measures can be taken to decrease the probability of developing exercise fear in patients.
