           Background: Surgical patients have risk of malnutrition on pre- and post-operative periods. Important factor that
increases this risk is the reduction of food intake. Nutritional assessment by food consumption evaluation is important and
necessary.
           Objective: The aim of this study was to evaluate the accuracy of self-administered dietary evaluation form by
comparing the total energy and protein intake between the self-administered dietary evaluation form and weighted caloric
count.
           Methods: A prospective study from 230 surgical patients who eat soft or regular diet. Each patient will fill out the selfadministered
dietary form and then calculate the total energy (Kcal) and protein intake (grams) compared to the standard
method from weighted food caloric count.
           Results: The mean total energy intake from the self-administered dietary evaluation form and the caloric count were
367.73±183.87 and 382.55±217.41 Kcal (p-value<0.05). The mean of protein intake was 11.32±6.19 and 11.57±7.74 gm (pvalue=
0.19), respectively. There is no difference of total energy and protein intake in soft diet group (p-value=0.114 and 0.517,
respectively), but significant difference in regular diet group. In subgroup analysis, if percent of difference in two group was
less than 20%, the accuracy of self-administered dietary evaluation form was 61.7%.
          Conclusions: Self-administered dietary evaluation form can be used to assess total energy and protein intake in
patients with soft diet. But if the accept of difference is less than 20%, it can be used in both soft and regular diet with
accuracy rate of 61.7%
