Objective The aim of this study was to evaluate the effect of a dietary management model based on empower-ment theory on the improvement of nutritional status and dietary treatment attitudes of maintenance haemodialysis(MHD)patients,so as to validate the effectiveness of empowerment theory in enhancing the self-management ability and quality of life of MHD patients.Methods The clinical data of 130 patients with MHD who were treated in Hangzhou First People's Hospital from January 2019 to January 2022 were retrospectively analyzed.The patients were divided into em-powering theory intervention group(n=65)and routine intervention group(n=65)according to patient intervention.The patients in the routine intervention group received routine nursing,and the patients in the empowering theory inter-vention group received diet management based on empowerment theory.The modified quantitative subjective global as-sessment of nutrition(MQSGN)score,attitude scale for the dietary therapy of hemodialysis patients(ASDTH)score,albumin(ALB),prealbumin(PAB),hemoglobin(Hb),blood phosphorus and blood calcium were compared.Results The MQSGN score of the empowering theory intervention group was less than the routine intervention group[(18.41±4.78)points vs.(21.42±4.31)points,P<0.05].The ASDTH score of the empowering theory intervention group was higher than the routine intervention group[(44.07±2.37)points vs.(38.46±2.54)points,P<0.05].Compared with routine intervention group,the levels of PAB,ALB and Hb of empowering theory intervention group were increased,and blood phosphorus was decreased,the differences were statistically significant(P<0.05).There was no difference in blood calcium between the two groups(P>0.05).Conclusion Diet management based on empowerment theory for MHD patients can help improve compliance and nutritional status.
