“…The possibility of the young women's unawareness was excluded given the fact that most of the subjects (n = 30) were students of nutrition-related subjects (dietetics/food technologies). In an effort to avoid such problems, all the issues encountered by keepers of food diaries should be considered in order to fully understand their experiences and create future systems to facilitate keeping a food journal (Mackenzie et al, 2022).…”

The research aim was to verify the theoretic energy requirement of young women and to calculate correlations between body mass index (BMI) and energy requirement, on the one hand, and the parameters obtained from bioelectrical impedance analysis on the other. The study was conducted in a group of 32 women grouped based on their BMI: underweight n = 8, normal weight n = 15, and overweight n = 9. Predictive formulas were observed to underestimate the energy requirement compared to values obtained with the use of ergospirometry. The smallest difference in Resting Energy Expenditure (REE) estimates using an ergospirometry apparatus was observed for the Cunningham equation (underweight: 1507 vs 1350 kcal) and the Harris-Benedict equation (normal weight: 1641 vs 1437 kcal; overweight: 1882 vs 1609 kcal). A significant statistical correlation was recorded in the juxtaposition of BMI to weight in the normal weight and in the overweight group. REE estimation based on formulas has only limited predictive value. Indirect calorimetry is recommended for measuring the REE rather than predictive equations.

Background Intake24, a web-based 24-hour dietary recall tool developed in the United Kingdom, was adapted for use in New Zealand (Intake24-NZ) through the addition of a New Zealand food list, portion size images, and food composition database. Owing to the customizations made, a thorough evaluation of the tool’s usability was required. Detailed qualitative usability studies are well suited to investigate any challenges encountered while completing a web-based 24-hour recall and provide meaningful data to inform enhancements to the tool. Objective This study aims to evaluate the usability of Intake24-NZ and identify improvements to enhance both the user experience and the quality of dietary intake data collected. Methods We used a mixed methods approach comprising two components: (1) completion of a single 24-hour dietary recall using Intake24-NZ with both screen observation recordings and collation of verbal participant feedback on their experience and (2) a survey. Results A total of 37 participants aged ≥11 years self-completed the dietary recall and usability survey (men and boys: 14/37, 38% and women and girls: 23/37, 62%; Māori: 10/37, 27% and non-Māori: 27/37, 73%). Although most (31/37, 84%) reported that Intake24-NZ was easy to use and navigate, data from the recorded observations and usability survey revealed challenges related to the correct use of search terms, search results obtained (eg, type and order of foods displayed), portion size estimation, and associated food prompts (eg, did you add milk to your tea?). Conclusions This comprehensive usability study identified challenges experienced by users in completing a dietary recall in Intake24-NZ. The results informed a series of improvements to enhance user experience and the quality of dietary data collected with Intake24-NZ, including adding new foods to the food list, optimizing the search function and ordering of search results, creating new portion size images, and providing clearer instructions to the users.
