Abstract
Objective: This study aimed to identify latent classes of adherence for serum phosphorus control and their influencing factors among patients receiving Peritoneal Dialysis with hyperphosphatemia.
Methods: This cross-sectional study using convenience sampling was conducted among patients receiving peritoneal dialysis with hyperphosphatemia between December 2024 and May 2025. Participants were assessed using the Phosphate Control Adherence Scale, Self-Efficacy Scale, and Family Care and Social Support Scale. Demographic and clinical data were also collected. Latent profile analysis (LPA) was used to identify adherence subgroups. Univariate analysis and multicollinearity diagnostics were performed, followed by binary logistic regression to determine predictors of adherence.
Results: Blood phosphorus control adherence can be classified into two categories: the low-level medical adherence group, characterized by poor dietary self-control (19.93%), and the high-level medical adherence group, marked by effective medication adherence (80.07%). The results indicated that residence conditions, types of medication, and self-efficacy significantly influenced blood phosphorus control adherence among patients with various forms of PD hyperphosphatemia (all p < 0.05).
Conclusion: Patients with hyperphosphatemia undergoing peritoneal dialysis exhibit heterogeneity in adherence to serum phosphorus control. This indicates that healthcare providers should identify the adherence characteristics of different patient groups at an early stage and implement targeted intervention strategies to enhance patients' adherence to serum phosphorus management.
