Estimated dietary sodium intake in haemodialysis patients using food frequency questionnaires.


ABSTRACT: In clinical practice, dietary sodium assessment requires reliable and rapid screening tools. We wished to evaluate the usefulness of food frequency questionnaires (FFQ) in estimating dietary sodium intakes in haemodialysis patients.We used the Derby Salt Questionnaire (DSQ), and Scored Sodium Questionnaire (SSQ) to estimate sodium intake. Body composition was determined by bioimpedance.In total, 139?haemodialysis patients (95 men) completed the FFQs, with mean?±?standard deviation age 67 ±?15?years. The mean FFQ scores were DSQ 3.5?±?2.0 and SSQ 68.4?±?24.5. Men had higher estimated dietary sodium intakes [DSQ median (range) 3.6 (0.6-10.1) versus female 2.2 (0.5-9.1), P?=?0.007)]. Younger patients and those aged >75?years had the higher SSQ dietary sodium scores; 70.7?±?27.8 and 76.8?±?24.6 versus those aged 55-75?years, 61.8?±?22.3, P?=?0.04. Patients with greater estimated sodium intake had higher extracellular water (ECW) to intracellular water (ICW) ratios pre-dialysis [75.1?±12.5 versus 67.7?±?4.8, P?
