Abstract
Objective: To evaluate dietary sodium intake in people with chronic kidney disease (CKD) and identify contributing factors tolow sodium intake by applying the Theory of Planned Behaviour (TPB) framework.Design and Methods:Non-dialysed people with CKD completed a 24-hour urinary sodium excretion test and ScoredSalt Questionnaire (SSQ). A survey including socio-demographic information, Brief Illness Perception Questionnaire, ShortSodium Knowledge Survey and Dietary Sodium Restriction Questionnaire based on TPB measured the factors contributing todietary adherence.Results:Sixty-three people [age: 71 (IQR: 64-77); 27% female] participated with 80% having high urinary sodium excretion[median: 134 mmol/day (111; 183)] but only 40% reported high sodium intake [SSQ score=53 (39; 75)]. Overall sodiumknowledge was high in 57% of participants although only 33% had seen a dietitian. There was a positive correlationbetween attitude towards a low-sodium diet and subjective norm (social expectations), r=0.44, p<0.01; urinary sodiumand the extent of perceived consequences of CKD (r=0.26, p<0.05); and the extent to which willpower was perceived as abarrier to adherence to dietary sodium restriction (r=0.27, p<0.05). Multiple regression analysis revealed taste of low-saltfoods (β=8.9, p<0.01) explained 26.4% of variance in dietary sodium intake (R2=0.264, F(12, 34), p<0.01).Conclusion:TPB successfully identified barriers to follow a low-sodium diet in non-dialysed people with CKD. Tastepreferences, willpower, meeting social expectations and disease concern were identified as key contributing factors to adherence.
