Objective: To estimate the prevalence of hyperphosphatemia and its correlation with dietary phosphorus intake in individuals undergoing hemodialysis in a medium-sized Brazilian municipality. Methods: This is a cross-sectional study with adult and elderly patients of both sexes undergoing treatment at a dialysis center in a medium-sized Brazilian municipality. Data were collected through a structured questionnaire containing sociodemographic questions, biochemical examination, and three 24-hour dietary recall interviews. Results: The final sample consisted of 75 participants, the majority of which were male (54.7%) and in the 36–59 years age group (56%). The prevalence of hyperphosphatemia was 45.9%, and 21.3% of participants had a dietary phosphorus intake above the recommended limits. However, there was a negative and significant correlation (P = 0.01) between phosphorus intake and serum phosphorus concentration. Conclusion: The prevalence of hyperphosphatemia in the studied sample of hemodialysis patients was high but showed a low correlation with dietary phosphorus intake, suggesting that it may be associated with nondietary factors such as ineffective hemodialysis or low adherence to phosphate binder therapy.
