Mobile ecological momentary dietary assessment (mEMDA) enables real-time dietary capture, reducing memory load and minimizing reactivity. This study describes the user-centered development and iterative usability testing of Edna, a research-quality mEMDA platform for large-scale, low-burden dietary surveillance. Edna integrates real-time self-report with an image-supported, demographically inclusive food list derived from NHANES data and automated linkage to USDA nutrient databases. Here, we describe Edna’s development and usability in diverse U.S. adults. METHODS: Three sequential rounds of iterative, user-centered development and usability testing were conducted between June 2024 and June 2025. Participants (N = 146 U.S. adults, ages 19–65 years) were recruited nationally through recruited nationally through an online research volunteer registry using stratified sampling by age, sex, BMI, and geographic region. Participants were randomly assigned to event-contingent or interval-contingent sampling conditions and asked to log all dietary intake for 14 consecutive days. Development refinements were guided by quantitative usability metrics and structured participant feedback through daily surveys and end-of-study questionnaires between rounds. Primary outcomes included System Usability Scale (SUS) scores, percentage of days with logged entries (engagement), and interval completion (interval-contingent only). The app was iteratively refined between rounds based on user feedback until SUS scores plateaued (change < 3 points). Statistical analyses included independent samples t-tests and ANOVA. RESULTS: SUS scores increased from 71.7 (SD = 23.0) in Round 1 to 78.8 (SD = 19.3) in Round 3, exceeding the digital health app benchmark of 68. Engagement ranged from 92.5 to 97.6% of study days, and interval completion among interval-contingent users ranged from 76 to 87%. Participants rated portion-size images as clear and culturally inclusive, with 94% reporting excellent overall experience.

As the use of legumes among Finnish children is marginal, there is potential for a substantial increase in their consumption. However, food education delivered through early childhood education and care (ECEC) settings has rarely focused specifically on environmentally sustainable foods, such as legumes. This study describes the implementation and effectiveness of an ECEC-delivered food education intervention within the FoodStep study. METHODS: The partially cluster-randomized FoodStep intervention aimed to increase the supply of vegetables, legumes, fruits, berries, and sustainable fish while reducing the provision of other animal-based foods in the intervention ECEC centres. The control centres maintained their regular menus. Food education materials and training were included to support the acceptability of the menu changes. Based on implemented food education activities reported by the ECEC professionals during the 10-month intervention, the ECEC centres were classified into high-intensity intervention (n = 5), low-intensity intervention (n = 6), and control group (n = 12). Parents of the participating 3- to 5-year-old children (n = 86) reported their child’s willingness to taste foods using a five-point scale. Food consumption was assessed using two separate food frequency questionnaires: (1) foods consumed outside ECEC and (2) foods consumed in ECEC. We used linear mixed models to examine the effectiveness of the food education intervention in increasing food acceptance and consumption. RESULTS: Commonly implemented food education activities were sensory food education, books and drama, gardening, and crafting. Compared with the control group, the children in the high-intensity intervention group showed higher acceptance of (β = 4.27, 95% CI − 0.03 to 8.57, p = 0.06), and consumed more, legumes at the follow-up (β = 1.18, 95% CI 0.31 to 2.06, p = 0.01). No statistically significant associations were observed for the other food groups. CONCLUSIONS: ECEC-delivered food education interventions accompanied by accessible materials and activities can help to promote sustainable diets in children by increasing the acceptability and consumption of environmentally sustainable foods, such as legumes. To encourage sustainable diets, menu modifications should be supplemented with pedagogic food education activities in ECEC centres.

The development of behaviour change interventions requires understanding context-specific determinants, which may differ across domains of transportation, occupational, and leisure time sedentary behaviour. This study aimed to use the Behaviour Change Wheel to inform the development of domain-specific intervention strategies for reducing prolonged sedentary behaviour among Canadian adults. METHODS: One-on-one semi-structured interviews were conducted with a diverse sample of adult participants from across Canada. Determinants of reducing prolonged sedentary behaviour were identified through thematic analysis and characterized according to their relevance to domains of transportation, occupational, and leisure time sedentary behaviour. The Behaviour Change Wheel and Behaviour Change Techniques Taxonomy (BCTTv1) were used to identify intervention strategies, components, and modes of delivery specific to and across behavioural domains. RESULTS: Thirty participants were interviewed (63% women, 60% age 25–44, and 50% identified as white). While all participants endorsed potential benefits of and personal goals related to reducing prolonged sedentary time, many had difficulty implementing these changes in their day-to-day life. Most participants identified leisure time as the domain in which they were most keen to reduce prolonged sedentary time. Barriers to reducing sedentary behaviour varied by domain: transportation-related barriers were primarily linked to physical opportunity, occupational barriers to social opportunity, and leisure time barriers to automatic motivation. Intervention techniques including prompts/cues, self-monitoring, and goal setting were identified to overcome barriers to reducing sedentary behaviour across domains. Restructuring the physical and social environment were identified as being particularly significant for enabling behaviour change in transportation and occupational domains, respectively. CONCLUSIONS: Individual-level interventions, such as goal-oriented prompts or cues, may be well-suited to reducing leisure time sedentary behaviour. In contrast, multilevel interventions, including organizational social restructuring and urban planning policy changes may be needed to address significant opportunity-related barriers in occupational and transportation domains. </p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13255465/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147787868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
