The protocol of the study.

Table 1

Components of the Diet Quality Index-International (DQI-I)

Adapted from Yun et al. (2009)

1) The criteria of score is based on the RI value for Korean

2) RI: recommended intakes

3) Ratio of energy from carbohydrate to protein to fat following DRIs for Korean

4) P/S: ratio of PUFA to SFA intake

5) M/S: ratio of MUFA to SFA intake

6) MUFA: monounsaturated fatty acids

7) SFA: saturated fatty acids
