TL;DR

This cross-sectional study validated a new food frequency questionnaire for high-sodium foods (FFQ-FHS) in 50 adults. The FFQ-FHS was found to be reproducible over 6 months but not valid for accurately assessing sodium intake compared to 24-hour recalls and a urinary biomarker.

Full summary

391 CHARS

This cross-sectional validation study assessed a food frequency questionnaire for high-sodium foods (FFQ-FHS) in 50 adults. The design included two administrations of the FFQ-FHS, four 24-hour dietary recalls (24hR), and two 24-hour urinary sodium excretions as a biomarker. The implication is that the FFQ-FHS should not be used alone for sodium assessment but may complement other methods.

ABSTRACT

This study aimed to validate a food frequency questionnaire for foods high in sodium (FFQ-FHS) in a population aged ≥18 years and to test its reproducibility. This cross-sectional study included 50 individuals (≥18 years) of both sexes. In addition to the FFQ-FHS, four 24-h dietary recalls (24hRs) were conducted and a socioeconomic and lifestyle questionnaire was administered. Two 24-h urinary excretions were collected for sodium analysis, and anthropometry was performed. For validation, the triad method was applied using the validity coefficient (ρ). For reproducibility, the intraclass correlation coefficient (ICC), 95% confidence interval, kappa coefficient, and Bland–Altman plots were used to check for agreement. The Kolmogorov-Smirnov test was used to verify the data distribution. The validity coefficients for daily energy-adjusted sodium intake were high for the 24hR (ρRAI = 0.85) and weak for the FFQ-FHS (FFQAI = 0.26) and biomarker (ρBAI = 0.20). The ICC values were 0.68 for unadjusted sodium and 0.54 for energy-adjusted sodium intake. The weighed Kappa scores were 0.49 (p<0.01) and 0.260 (p = 0.02) for unadjusted and adjusted sodium intake, respectively. Although the FFQ-FHS is reproducible, it is not valid for the assessment of sodium intake and cannot be the sole instrument used for this purpose.
