Development and validation of processed foods questionnaire (PFQ) in adult inflammatory bowel diseases patients
Goal
Develop a validated processed foods frequency questionnaire (PFQ) and assess its reliability and validity.
Results
Eighty-six IBD patients were enrolled. Good test–retest reliability was indicated by intraclass correlation of 0.75–0.88 for the different food processing levels. Validity was fair-to-strong as assessed by correlations for different levels of processed food intake between FDs and PFQ, ranging between 0.43 and 0.64 (Pearsonr, P_<_0.001), and further supported by higher mean urine sodium levels in patients with high processed foods consumption compared with low consumption (104.57_±_53.26 vs. 78.62_±_39.08_mmol/L, respectively, P_=_0.022). Agreement between PFQ and the FD in categorizing patients to high and low processed food consumption groups was fair (Kappa 0.23–0.35).
