Previous research has shown significantly reduced mortality in haemodialysis (HD) patients supplemented with water-soluble vitamins (Fissel et al., 2004). HD patients have increased requirements along with altered intake, metabolism and absorption of micronutrients due to the build up of uraemic toxins and the treatment of dialysis, diet and medication. Renal recommended intakes (RRI) acknowledge this increased need (Fouque, 2003). The aim of this study was to establish the adequacy of micronutrient intake in a cohort of HD patients attending Portsmouth dialysis unit. Methods: A random sample ( n = 24) of stable HD patients completed 5-day food diaries, these were analysed for energy, protein and micronutrient intake using Windiets. Descriptive statistics; t-tests; correlation and regression, as appropriate for data distribution, were performed using SPSS (v14). Individual mean energy and protein intake were compared to requirements (DH, 1991). Micronutrient intakes were compared to the reference nutrient intakes (DH, 1991) and renal recommended intakes (Fouque, 2003). Mean nutrient intake was compared to age; duration on dialysis; gender and marital status ( n = 24). Intake on dialysis and non-dialysis days was compared ( n = 7). Ethical approval was applied for with the conclusion this was an audit. Results: Mean protein intake was adequate [71 g day−1 (SD 24)], while energy intake was inadequate [8095 kJ day−1 (SD 2241)]. There were no significant relationships between nutrient intake and age, gender or marital status. Those who had been on dialysis longer had significantly reduced intakes of protein, niacin, pyridoxine and selenium ( P < 0.05) as shown in Table 1 . There was no significant difference between intake on dialysis and non-dialysis days. Discussion: The intake of many micronutrients in a substantial proportion of patients appeared poor, which may exacerbate relative deficiencies due to altered metabolism. [ABSTRACT FROM AUTHOR]
