Description of intervention(s) / exposure
This is a cross-sectional pilot study to assess the usability and acceptability of the mobile food record (mFR) to measure dietary intake in children and adolescents with Type 1 diabetes (T1D).
Metadata of before and after images of all consumed foods and beverages captured by the app of 50 participants during four consecutive days will be collected. The data will allow assessment of eating frequency (number of eating occasions) and enable researchers to view the time of images alongside continuous glucose monitoring (CGM) traces. Micro- and macronutrient intakes will be assessed against clinical measures, diabetes nutrition guidelines, Australian Dietary Guidelines and Nutrient Reference Values. At completion, participants will be asked to complete an online usability questionnaire and provided with feedback on their average daily food group intake.
A trained Research Assistant will be trained in the set up and usage of the Mobile Food Record App and will email a link to participants to download the App onto their personal mobile devices.
Participants will take photos of all consumed foods and beverages during 4 consecutive days. The App use is anticipated to take approximately 30 seconds to capture one food image. Participant will upload their CGM traces to the appropriate and secure diasend or carelink online-based cloud which will be accessible by a member of the research team to download trace date for assessment.

Outcomes
Primary outcome [1] 326215 0
1) Usability of images captured using the mFR App by children and adolescents with Type 1. The usability will be assessed by reseachers using an online usability questionnaire. This questionnaire has been previously developed and tested in young and healthy adults participating in a similar study design. The answers provided by all participants will be a measure of usability that may lead to modifications to improve its features for future use.
Timepoint [1] 326215 0
Post completion of the 4 day mFR
Primary outcome [2] 326558 0
2) Acceptability of the using the mFR App by children and adolescents with Type 1.
The acceptability will be assessed by reseachers using an online acceptability questionnaire which will be completed by all participants. This questionnaire has been previously developed and tested in young and healthy adults participating in a similar study design.

Efficacy
Statistical methods / analysis
Given the resources and time available for this cross-sectional pilot study, a sample size of 50 has been identified as feasible.
Food and nutrient intake will be estimated and compared to National Reference Values (NHMRC, 2019), Australian Dietary Guidelines food serve recommendations (NHMRC, 2013) and current paediatric diabetes nutrition guidelines. Associations between dietary intake, age, gender, diabetes duration, BMI z-score and HbA1c will be explored.
P values of < 0.05 will be used to determine statistical significance.
