Objective To investigate the current status and influencing factors of fluid intake behavior in maintenance hemodialysis(MHD)patients.Methods A total of 205 MHD patients treated in The Central Hospital Affiliated to Shandong First Medical University from Jan.to Dec.2021 were recruited by the conve-nience sampling method.Their health belief and knowledge level were evaluated by using the Liquid Intake Health Belief Scale and Knowledge Level Questionnaire.The influencing factors for fluid intake behavior were then analyzed.Results In the 205 MHD patients,fluid intake behaved in the stage of unintention in 21 patients(10.2％),intention in 42 patients(20.5％),preparation in 43 patients(21.0％),action in 73 patients(35.6％),and maintenance in 26 paticnts(12.7％).When age,fluid intake self-efficacy,and knowledge level in-creased by one unit,the likelihood of progression to a higher stage of fluid intake behavior increased by 3.7％(OR=1.037,95％CI:1.010～1.065,P=0.007),18.7％(OR=1.187,95％CI:1.142～1.234,P＜0.001),and 8.0％(OR=1.080,95％Cl:1.006～1.160,P=0.033)respectively.When the average interdialytic weight gain de-creased by one kilogram,the likelihood of progression to a higher stage of fluid intake behavior increased by 51.0％(OR=0.490,95％CI:0.330～0.727,P＜0.001).Conclusion Age,average interdialytic weight gain,self-efficacy of fluid intake and knowledge level are the influencing factors for fluid intake behavior in MHD patients.
