Validation of a New Food Frequency Questionnaire for Protein Intake Assessment in Korean.

ABSTRACT:

Background

Protein intake is a modifiable factor associated with sarcopenia prevention; however, no appropriate methods exist to assess dietary protein intake in Koreans. This study developed and validated a simple and convenient food frequency questionnaire (FFQ) to determine protein intake in Koreans.

Methods

A total of 120 participants aged >19 years were asked to complete both the FFQ used by the Korean National Health and Nutrition Examination Survey (KNHANES) and the newly developed Korean Protein Assessment Tool (KPAT). Protein intakes measured using the FFQ and the KPAT were compared using Pearson correlation coefficients, Bland-Altman plots, and intraclass correlation coefficients.

Results

Protein intakes from the FFQ (62.06±25.56 g/day) and KPAT (61.12±24.26
