Abstract
Background: Intradialytic hypertension (IDH) is defined as a rise in blood pressure during or immediately after hemodialysis that is associated with increased mortality in these patients. This study aimed to evaluate the association between IDH and the nutritional intake of trace and micromineral elements in maintenance hemodialysis patients.
Methods: Patients with chronic renal failure treated with maintenance hemodialysis were assessed in this case-control study. The participants who had IDH were selected as the case group. The Food Frequency Questionnaire (FFQ) was used to collect nutritional data; and then, the diets of the two groups were analyzed. Totally, 23 patients with IDH and
23 without IDH were included in the analysis.
Results: Although there was no significant difference in daily calorie intake between the two groups, the mean dietary intake of sodium, calcium, phosphorus, and total fat was significantly higher in the IDH group than the control group (p<0.05). In the group with IDH, the phosphorus intake was higher than the recommended amount, while the
control group consumed significantly less oral phosphorus.
Conclusion: Advising limiting oral phosphorus and sodium consumption along with low-fat diet may help to reduce blood pressure in IDH patients and the subsequent mortality.
