“…Trinidad and Tobago has the highest prevalence of morbidity and mortality for NCDs in the Caribbean (12). Studies conducted on this population often rely on anthropometric data to assess risk factors for morbidity and mortality in the adult population (17)(18)(19)(20). Other research studies rely on FFQ derived food and nutrient intake estimates that have not been validated or are not culturally speci c for this unique population (21)(22)(23).…”

Background Nutritional epidemiologists use culture-specific food frequency questionnaires (FFQs) to assess the dietary intake of groups based on country, region or ethnic groups. The aim of this study was to assess the performance of a self-constructed culture-specific semi-quantitative electronic FFQ (e-FFQ) in assessing food group intake estimates when compared with multiple 1-day food records (FRs) for the adult population of Trinidad and Tobago. Methods The 139-item semi-quantitative e-FFQ containing local dishes and street foods was created using Google forms. It was emailed twice, 3 months apart, to 91 participants ≥ 18 years of age. The first administration of the e-FFQ was validated against 4-four one-day FRs with digital photographs which served as the reference method. Using SPSS Version 26, the validity and reproducibility of the FFQ’s food group intake estimates were determined using paired t-tests, bivariate correlations, and cross-classifications. Cross-classification and Bland-Altman plots were used to show agreement between the e-FFQ and weighted mean of the FRs. Results Participants consisted of 22% males and 78% females, mean age 38 ± 9.6 years. Reproducibility correlations between the reported food group intakes in the first and repeat administration of the e-FFQ ranged from moderate (r = 0.44 p ≤ 0.0001) for sweetened beverages to high (r = 0.91 p ≤ 0.0001) for alcohol. Cross-classification agreements within ± 1 quintile ranged from 70% (street foods) to 92% (alcohol). Crude validity correlations between the e-FFQ and FR ranged from (r = 0.06) for sweets to (r = 0.65) for food from animal sources, with mean of the validity correlations being 0.34. Deattenuated correlations ranged from r = 0.11 for sweets to r = 0.81 for food from animal sources. Cross-classification showed that an average of 68% of the FFQ estimates were correctly classified within ± 1 quintile of exact agreement in the FRs. Agreements between the FFQ and the FRs ranged from 55% for street foods to 95% for water, all significant at p ≤ 0.0001. Conclusions The study shows that this culture-specific e-FFQ is highly reproducible and is a reasonably valid tool to assess and rank food group intake estimates of an adult population living in Trinidad and Tobago. Thus, it can be used to examine associations between dietary intakes and NCDs.

Nutritional epidemiologists use culture-specific food frequency questionnaires (FFQs) to assess the dietary intake of groups based on country, region or ethnic groups. This study aimed to validate a culture-specific semi-quantitative electronic Food Frequency Questionnaire (e-FFQ) to estimate food group intake in the adult population of Trinidad and Tobago. A 139-item semi-quantitative e-FFQ containing local dishes and street food was administered twice to adults 18 years and older and compared against four 1-day food records (FRs) using digital photographs, which served as the reference method. The validity and reproducibility of the e-FFQ food group intake estimates were determined using paired t-tests, bivariate correlations, and cross-classifications. Reproducibility correlations between the reported food group intakes in the first and repeat administration of the e-FFQ ranged from moderate ( r = .44, P ≤ .0001) for sweetened beverages to high ( r = .91 P ≤ .0001) for alcohol. The cross-classification agreements ranged from 70% (street food) to 92% (alcohol). Energy-adjusted deattenuated validity correlations between the e-FFQ and FR ranged from ( r = .08) for water to ( r = .81) for food from animal sources, with a mean validity correlation of .36. An average of 68% of the e-FFQ estimates was correctly classified within the ±1 quintile of the exact agreement with the FRs. Agreements between the e-FFQ and FRs ranged from 55% for street foods to 95% for water, all significant at P ≤ .0001. This study shows that the culture-specific e-FFQ is a valid tool for assessing and ranking food category intake estimates of the adult population living in Trinidad and Tobago.
