Association of socio-demographic characteristics, nutritional status, risk of malnutrition and depression with quality of life among elderly haemodialysis patients

Introduction: A compromised quality of life (QOL) as a result of haemodialysis (HD) is a rising global issue. Elderly HD patients face more challenges than younger counterparts. This study determined the association of socio-demographic characteristics, nutritional status, risk of malnutrition and depression with QOL, among elderly HD patients. Methods: A cross-sectional study was conducted among 112 HD elderly patients in selected dialysis centres in Selangor, Malaysia. The patients completed interview-based questionnaires on socio-demographic characteristics, risk of malnutrition (Dialysis Malnutrition Score, DMS), depression (Patient Health Questionaire-9, PHQ-9) and QOL (KDQOL-36). Anthropometric measurements, 24-hour dietary recall and food intake information were obtained from them and biochemical data from their medical records. Results: Just over half (50.9%) of the patients had a normal body mass index while 85.7% had optimal albumin levels. The proportion of patients who met the recommended energy and protein intakes were 19.0% and 3.4%, respectively. Patients were at moderate risk of malnutrition, had minimal depression level and perceived better QOL in terms of effects and symptoms of kidney disease. There was a significant positive correlation between protein intake and the physical domain of QOL (p=0.02) and negative correlation between risk of malnutrition with physical and mental composites of QOL (p<0.001). There was significant negative correlation between depression and physical composite, mental composite, burden, effects and the symptoms of kidney disease (p
