Biting into accuracy: Evaluating food frequency questionnaires for denture wearers: A systematic review

Abstract

Objectives: The correlation between denture usage and nutrition is a subject of ongoing debate, with numerous authors attempting to investigate it using food frequency questionnaires (FFQ). This systematic review aimed to assess the quality of research reporting on the use of FFQ as a tool for evaluating nutrient intake in individuals who wear dentures.


Methods: Studies were sourced through online databases, encompassing publications from 1990 to 2024. Four studies employing FFQ to evaluate the nutritional status of denture wearers and meeting the specified inclusion-exclusion criteria were incorporated into this systematic review. Quality assessment of the included studies was independently conducted by two reviewers, utilizing the summary score provided by Dennis et al.


Results: All the studies included in the review utilized semi-quantitative FFQ, with most adopting the widely accepted and validated FFQ developed by Willet and Block. The majority of these studies received high-quality scores as per the assessment criteria established by Dennis et al. However, one study under review received a low score due to several shortcomings. This included failure to report the FFQ items utilized in the study, lack of repetition in quality checks, absence of nutrient database utilization for FFQ coding, inadequate portion size estimation, and insufficient information regarding survey completion time.


Conclusion: The articles included in the review, along with their quality assessments, provided insights into various aspects of FFQ design that enhance validity. These include the comprehensiveness of items covered, frequency of intake reporting, accuracy of portion size calculations, choice of reference technique, and method of delivery. It was observed that the majority of studies favored the interview administration of FFQ, which was deemed to be more reliable and acceptable during quality analysis.
