Purpose: The purpose of this study was to investigate the status of hyperphosphatemia in patients with chronicrenal failure (CRF) and to examine the effects of dialysis-related characteristics, nutritional status, self-care,stress, and social support on hyperphosphatemia.
Methods: This descriptive research study was designed toidentify factors influencing the development of hyperphosphatemia in patients diagnosed with CRF. A con-venience sample of 150 patients receiving hemodialysis was selected. Data were collected directly by theresearchers from January to March 2022.
Results: The regression model showed statistically significant results(x2=137.24, p<.001). Regression analysis demonstrated that body mass index (BMI) and blood urea nitrogen(BUN) were predictive factors. The risk of hyperphosphatemia was 3.09 times (95% CI, 1.15~8.25) higher for aBMI ≥25 kg/m2 than for a BMI 18.5-22.9 kg/m2. The risk of hyperphosphatemia increased by 1.04 times (95%CI, 1.01~1.07) as the BUN levels increased.
Conclusion: BMI and BUN were identified as major predictive factorsfor hyperphosphatemia, which confirms the importance of nutritional intake in dialysis patients. To preventhyperphosphatemia in hemodialysis patients, regular monitoring for dietary and nutritional status and nutritioneducation based on the results of monitoring should be carried out. Interdisciplinary strategies are also neededto prevent hyperphosphatemia.
