Abstract: Objective: To investigate the compliance with phosphorus-controlled diets and its influencing factors in hemo-dialysis patients with hyperphosphatemia. Methods: A convenience sampling was used to recruit 172 hyperphosphatemic patients who underwent hemodialysis in two tertiary grade A hospitals in Guangxi from May 2018 to October 2019. Patients were investigated by a general information questionnaire, a dietary compliance questionnaire for hyperphosphatemic hemo- dialysis patients, and a low phosphorus diet health belief scale in hemodialysis patients with hyperphosphatemia. Results: The total score of dietary compliance of hyperphosphatemic patients was (36.39±3.55) and the overall compliance rate was 60.6%, which were at the moderate level. Multiple linear regression analysis showed that gender, education level, occupational status, dietary habits, and health beliefs about the low phosphorus diet were the influential factors of dietary compliance of hyperphosphatemic patients (P<0.05). Conclusion: The compliance of hyperphosphatemic Hemodialysis patients with phosphorus-controlled diets needs to be improved. In clinical settings, we need to pay more attention to patients who are male, employed, poorly educated, with poor dietary habits, and with weak believes in low phosphorus diet. Tailored and effective measures are suggested to these patients to improve their compliance with phosphorus-controlled diets.
