Objective: To explore the change trajectory of fluid load management ability in peritoneal dialysis patients and the correlation between different trajectories and physical activity. Method: A total of 243 patients undergoing peritoneal dialysis were selected. A longitudinal investigation was carried out on them using the Peritoneal Dialysis Patient Volume Management Behavior Scale and the International Physical Activity Questionnaire - Long. Results: Three trajectories of volume overload management behavioral ability were identified, namely, C1 (low - level increasing group), C2 (medium - level increasing group), and C3 (low - to - medium - level fluctuation group). There were significant differences among different categories in the cultural level trail (χ2 = 15.344, P = 0.018), diabetic nephropathy (χ2 = 11.267, P = 0.004), peritonitis during the study period (χ2 = 11.340, P = 0.003), and hypoalbuminemia (χ2 = 7.700, P = 0.021). During the first 6 months of initial peritoneal dialysis (T1~T4), each patient's physical activity scores increased [C1: (F = 107.250, P < 0.001); C2: (F = 45.383, P < 0.001); C3: (F = 30.194, P < 0.001)]. At the T1 stage, the physical activity score of group C2 was significantly higher than those of group C1 and group C3 (P < 0.01). At the T2 stage, the physical activity score of group C2 was significantly higher than that of group C3 (P < 0.001), and the score of group C1 was significantly higher than that of group C3 (P < 0.01). At the T3~T4 stage, the score of group C1 was significantly higher than those of group C2 and group C3 (P < 0.01), and the score of group C2 was significantly higher than that of group C3 (P < 0.001). Conclusions: Education level, diabetic nephropathy, concurrent peritonitis, and hypoproteinemia affect the change trajectory of volume load. Additionally, volume overload management at different stages influences the physical activity of patients.
