Abstract
This study investigates the association between dietary sodium intake, dialysis adequacy, nutritional status, and blood pressure among haemodialysis patients in Hospital Pakar Universiti Sains Malaysia (HPUSM). A cross-sectional study was conducted involving 73 patients aged 18 and above. Data were collected through standardised questionnaires, 2-day 24-hour dietary recalls, dialysis adequacy (Kt/V), and Dialysis Malnutrition Score (DMS). The median dietary sodium intake was 591 mg (IQR: 729 mg) in males and 400 mg (IQR: 526 mg) in females. Median systolic blood pressure was 166 mmHg (IQR: 35 mmHg) for males and 158 mmHg (IQR: 44.75 mmHg) for females. Diastolic blood pressure medians were 80 mmHg (IQR: 21 mmHg) for males and 78.5 mmHg (IQR: 17 mmHg) for females. Most participants achieved adequate dialysis. There was no difference in the median DMS between females (15, IQR: 5) and males (14, IQR: 5). The study found no statistically significant association between dietary sodium intake, dialysis adequacy, nutritional status, and blood pressure among the haemodialysis patients. However, to better understand the factors influencing blood pressure and improve patient outcomes, further research is recommended to explore potential causal relationships that can optimise dietary management among haemodialysis patients
