ObjectiveTo analyze the situations of dry weight control and its influencing factors in maintenance hemodialysis (MHD) patients. MethodsA total of 280 patients receiving maintenance hemodialysis treatment in our hospital from July 2018 to January 2021 were enrolled as the research objects. The dry weight of patients were measured by body composition analyzer, and the weight of patients before and after dialysis for 1 month were measured. The ratio of absolute value of weight difference before and after dialysis to dry weight was calculated. According to this ratio, 280 MHD patients were divided into strict dry weight control group and non-strict dry weight control group. Univariate and multivariate logistic regression analysis were performed on factors affecting the effect of dry weight control. ResultsUnivariate analysis results showed that there were statistically significant differences in diabetes history, average daily salt intake, average daily water intake, average daily residual urine volume, albumin (ALB) and NT-proBNP levels between strict dry weight control group and non-strict dry weight control group (P＜0.05). The results of multivariate logistic regression analysis showed that diabetes history, excessive average daily salt intake, excessive average daily water intake, and low ALB level were independent risk factors that affecting the poor control of dry weight in MHD patients. ConclusionPoor control of dry weight often occurs in MHD patients, diabetes history, excessive daily salt intake, excessive daily water intake and low ALB level are independent risk factors that affecting the poor control of dry weight.
