Exploring the feasibility of use of an online dietary assessment tool (myfood24) in women with gestational diabetes

Abstract

myfood24 is an online 24-hour dietary recall tool developed for nutritional epidemiological research. Its clinical application has been unexplored. This mixed methods study explores the feasibility and usability of myfood24 as a food record in a clinical population, women with gestational diabetes (GDM). Women were asked to complete five myfood24 food records, followed by a user questionnaire (including System Usability Scale (SUS) a measure of usability), and were invited to participate in a semi-structured interview. Of the 199 participants, mean age was 33 years, mean booking BMI 29.7kg/m2, 36% primiparous, 57% White, 33% Asian. Of these, 121 (61%) completed myfood24 at least once and 73 (37%) completed the user questionnaire; 15 were interviewed. The SUS was found to be good (mean 70.9, 95%CI 67.1, 74.6). Interviews identified areas for improvement, including optimisation for mobile devices and as a clinical management tool. This study demonstrates that myfood24 can be used as an online food record in a clinical population and has potential to support self-management in women with GDM. However, results should be interpreted cautiously given the responders’ demographic characteristics. Further research to explore barriers and facilitators of uptake in people from ethnic minority and lower socioeconomic backgrounds is recommended.
