AB  - OBJECTIVE: The aim of the current study was to evaluate the accuracy of the new 
      software eAT24 used to assess dietary intake in the National Food, Nutrition and 
      Physical Activity Survey (IAN-AF) against urinary biomarkers: N (nitrogen), K 
      (potassium) and Na (sodium). DESIGN: We conducted a cross-sectional study. Two 
      non-consecutive 24-h dietary recalls (24-HDR) were applied, and a 24-h urine 
      sample was collected. We examined differences between estimates from dietary and 
      urine measures, Pearson correlation coefficients were calculated and the 
      Bland-Altman plots were drawn. Multiple linear regression was used to evaluate 
      the factors associated with the difference between estimates. SETTING: Sub-sample 
      from the Portuguese IAN-AF sampling frame. PARTICIPANTS: Ninety-five adults (men 
      and women) aged 18-84 years. RESULTS: The estimated intake calculated using the 
      dietary recall data was lower than that estimated from urinary excretion for the 
      three biomarkers studied (protein 94.3 v. 100.4 g/d, K 3212 v. 3416 mg/d and Na 
      3489 v. 4003 mg/d). Considering 2 d of recall, the deattenuated correlation 
      coefficients were 0.33, 0.64 and 0.26 for protein, K and Na, respectively. For 
      protein, differences between dietary and urinary estimates varied according to 
      BMI (beta = -1.96, P = 0.017). The energy intake and 24-h urine volume were 
      significantly associated with the difference between estimates for protein (beta = 
      0.03, P < 0.001 and beta = -0.02, P = 0.002, respectively), K (beta = 0.71, P < 0.001 
      and beta = -0.42, P = 0.040, respectively) and Na (beta = 1.55, P < 0.001 and beta = 
      -0.81, P = 0.011, respectively). CONCLUSIONS: The new software eAT24 performed 
      well in estimating protein and K intakes, but lesser so in estimating Na intake, 
      using two non-consecutive 24-HDR.
