Description
Introduction: Patients with End-Stage Renal Disease (ESRD) undergoing hemodialysis must adapt to strict nutritional
and fluid restrictions to achieve optimal therapeutic outcomes. Nonadherence leads to complications and clinical
deterioration. This study examined psychosocial (knowledge, illness perception, family support) and clinical factors
(illness duration, comorbidities, and blood pressure) as predictors of nutritional status and fluid balance, measured by
biochemical markers and interdialytic weight gain (IDWG), among hemodialysis patients in West Sumatra.
Methods: This cross-sectional correlational study included 245 ESRD patients from four hemodialysis units in West
Sumatra. Knowledge, family support, and illness perception were measured using validated questionnaires.
Biochemical parameters (urea, creatinine, albumin, sodium, potassium, and hemoglobin) and IDWG served as proxies
for nutritional status and fluid balance. Data analysis was performed using Pearson’s correlation and t-test (α = 0.05).
Results: The mean age was 51.4±11.8 years, and 60% were male. Most patients had good knowledge (81.6%), strong
family support (90.6%), and positive perceptions (82%). A significant correlation was found between illness duration
and interdialytic weight gain (IDWG) (r=0.153, p<0.05). Notably, knowledge level was negatively correlated with urea
level (r = –0.127, p < 0.05), indicating that higher knowledge was associated with better nutritional control. Family
support was not significantly correlated with biochemical outcomes.
Conclusions: Patient knowledge emerged as an important predictor of biochemical indicators of nutritional status,
whereas dialysis duration predicted fluid imbalance as reflected by IDWG. Family support, although prevalent, did not
significantly influence the clinical outcomes related to nutrition and fluid control. Strengthening educational strategies
may enhance adherence to treatment and improve clinical outcomes.
