“…Hence, it is expected that these devices will continue to be popular and become an accepted method to gather medical information as well as deliver care [ 43 ]. Factors such as acceptability and comfort with technology were identified in our study as being more important than the patient’s age, which is consistent with other reports [ 11 , 44 ].…”

“…Multiple barriers need to be addressed before implementation of e-DA tools in team-based PC. Many of the potential barriers identified in both focus groups and web-based surveys are consistent with the literature [ 6 , 44 , 48 - 50 ]. An additional barrier for patients identified in our study was the inappropriate use of e-DA tools, which could perpetuate extreme or obsessive calorie counting in some individuals with eating disorders.…”

BackgroundDietary assessment can be challenging for many reasons, including the wide variety of foods, eating patterns and nutrients to be considered. In team-based primary care practice, various disciplines may be involved in assessing diet. Electronic-based dietary assessment (e-DA) instruments available now through mobile apps or websites can potentially facilitate dietary assessment. Providers views of facilitators and barriers related to e-DA instruments and their recommendations for improvement can inform the further development of these tools. The objective of this study was to explore provider perspectives on e-DA tools in mobile apps and websites.MethodsThe exploratory sequential mixed methods design included interdisciplinary focus groups followed by a web-based survey sent to Family Health Teams throughout Ontario, Canada. Descriptive and bivariate analyses were completed. Focus group transcripts contributed to web-survey content, while interpretive themes added depth and context.Results11 focus groups with 50 providers revealed varying perspectives on the use of e-DA for: 1) improving patients’ eating habits; 2) improving the quality of dietary assessment; and, 3) integrating e-DA into the care process. In the web-survey 191 respondents from nine disciplines in 73 FHTs completed the survey. Dietitians reported greater use of e-DA than other providers (63% vs.19%; p = .000) respectively. There was strong interest among disciplines in the use of e-DA tools for the management of obesity, diabetes and heart disease, especially for patient self-monitoring. Barriers identified were: patients’ lack of comfort with using technology, misinterpretation of e-DA results by patients, time and education for providers to interpret results, and time for providers to offer counselling.Conclusionse-DA tools in mobile apps and websites may improve dietary counselling over time. Addressing the identified facilitators and barriers can potentially promote the uptake of e-DA into clinical practice.

“…Using such web-based technology to collect dietary intake data offers the opportunity to make an appealing interface that is especially engaging to children, adolescents, and younger adults, who are familiar with the technology in their daily lives. Computerized diet programmes get high ratings as ‘enjoyable’ and ‘easy to use’ ( 14 ). A number of web-based methods have proved both feasible and acceptable when used with children ( 7 , 9 , 15 – 17 ).…”

BackgroundThe OPUS (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet) project carried out a school meal study to assess the impact of a New Nordic Diet (NND). The random controlled trial involved 834 children aged 8–11 in nine local authority schools in Denmark. Dietary assessment was carried out using a program known as WebDASC (Web-based Dietary Assessment Software for Children) to collect data from the children.ObjectiveTo compare the energy intake (EI) of schoolchildren aged 8–11 estimated using the WebDASC system against the total energy expenditure (TEE) as derived from accelerometers worn by the children during the same period. A second objective was to evaluate the WebDASC's usability.DesignEighty-one schoolchildren took part in what was the pilot study for the OPUS project, and they recorded their total diet using WebDASC and wore an accelerometer for two periods of seven consecutive days: at baseline, when they ate their usual packed lunches and at intervention when they were served the NND. EI was estimated using WebDASC, and TEE was calculated from accelerometer-derived activity energy expenditure, basal metabolic rate, and diet-induced thermogenesis. WebDASC's usability was assessed using a questionnaire. Parents could help their children record their diet and answer the questionnaire.ResultsEvaluated against TEE as derived from the accelerometers worn at the same time, the WebDASC performed just as well as other traditional methods of collecting dietary data and proved both effective and acceptable with children aged 8–11, even with perhaps less familiar foods of the NND.ConclusionsWebDASC is a useful method that provided a reasonably accurate measure of EI at group level when compared to TEE derived from accelerometer-determined physical activity in children. WebDASC will benefit future research in this area.

“…The foods were grouped using a combination of iterative statistical analyses of the National Nutrition Survey data of Australia and professional judgement. A prototype of this programme (a website) was created for think‐aloud usability testing with potential end‐users (Probst & Tapsell, 2007). This usability testing was video recorded (Probst et al.…”
