Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dietary assessment is critical for dietary research. Food Frequency Questionnaires (FFQ) measure habitual dietary intake and are low user and researcher burden. The ZOE AFFIRM study aims to assess the relative validity of a novel FFQ compared to a widely accepted 24h dietary recall tool in a remote setting.

Research Question:

What is the relative validity of a novel FFQ (Food Frequency Questionnaire) compared to a widely accepted 24h dietary recall tool in a remote setting?

Research Aim:

This study aims to relatively validate the ZFFQ (ZOE Food Frequency Questionnaire; ZOE Ltd) by assessing its agreement with a widely accepted 24h diet recall tool, Intake24 (Newcastle University) in a remote population.

Design:

This study will be conducted in a single-arm design with the intake period under assessment comprising one month.

1. Participants will complete two periods of 3 consecutive days each (one weekend-day and two weekdays, i.e. Sunday-Tuesday or Thursday-Saturday), in which they will complete 6 total rounds of Intake24 (one completion per previous 24 hours). The two periods must be at least 14 days apart; participants will be given multiple options of dates to choose from in November/December that satisfy these requirements.
2. Once the two recall periods are completed, the participant will be asked to fill out the ZFFQ recalling food frequency (without portion sizes) over the preceding month (which encompasses the two recall periods).

Population: In brief, participants are generally healthy UK-based adults who provided consent to participation in this remote study. Please see the eligibility section for full criteria. Participants provided consent before undertaking any study procedures.

Data analysis: Agreement analysis will be used to compare both dietary assessment methods and evaluate the relative validity of the ZOE FFQ.

Data collection:

* Baseline demographic data (age, sex, BMI, ethnicity, smoking, socio-economic status)
* Dietary data (FFQ and 24hr dietary recall)
