O-71 The adaptation and implementation of an automated 24-hour dietary recall tool for Caribbean populations: St. Vincent and the Grenadines pilot study

Methods: This was a pilot study conducted in SVG among participants aged ≥16 years enrolled in a backyard garden intervention. Intake24 was adapted by developing a Caribbean-specific food database, incorporating locally consumed foods and naming conventions, assigning appropriate portion-size estimation methods, and linking foods to nutrient composition codes. Trained interviewers administered one 24-hour dietary recall per participant per week for up to three consecutive weeks at baseline. Dietary intake data were summarized using descriptive statistics to estimate mean daily energy, macronutrient, and micronutrient intakes.

Results: The adapted Intake24 database included 3,291 food and drink items, with 25 newly added Caribbean-specific foods and mixed dishes. After data cleaning, 57 participants were included in the analysis (mean age 48.5 ± 14.5 years; 70.2% female). Mean daily energy intake was 1,905.1 ± 842.3 kcal. Mean daily intakes of carbohydrates, protein, and fat were 249.9 ± 98.8 g, 94.8 ± 40.6 g, and 65.3 ± 42.4 g, respectively. Intakes of key micronutrients, including calcium, iron, and vitamin A, varied widely across participants.

Conclusion: The adapted Intake24 tool was implemented in a Caribbean setting and was able to capture individual-level dietary intake data in SVG. The findings indicate variability in energy and micronutrient intake and suggest potential nutrient deficiencies in this population. Intake24 shows promise as a scalable tool for dietary assessment and nutrition surveillance in the Caribbean.
