“…A recent randomised trial of a phone app that provides feedback on potential food purchases (suggesting switches for lower salt products) found a significant reduction of salt in food purchases of 0.3g/MJ (0.03, 0.58) in a study of 66 adults with diagnosed cardiovascular disease [51], suggesting feedback on nutritional content of foods combined with proposed alternatives could be an effective mechanism for improving diets.…”

BACKGROUND Most food in the United Kingdom is purchased in supermarkets, and many of these purchases are routinely tracked through supermarket loyalty card data. Using such data may be an effective way to develop remote public health interventions and to measure objectively their effectiveness at changing food purchasing behavior. OBJECTIVE The Front-of-pack food Labels: Impact on Consumer Choice (FLICC) study is a pilot randomized controlled trial of a digital behavior change intervention. This pilot trial aimed to collect data on recruitment and retention rates and to provide estimates of effect sizes for the primary outcome (healthiness of ready meals and pizzas purchased) to inform a larger trial. METHODS The intervention consisted of a website where participants could access tailored feedback on previous purchases of ready meals and pizzas, set goals for behavior change, and model and practice the recommended healthy shopping behavior using traffic light labels. The control consisted of Web-based information on traffic light labeling. Participants were recruited via email from a list of loyalty card holders held by the participating supermarket. All food and drink purchases for the participants for the 6 months before recruitment, during the 6-week intervention period, and during a 12-week washout period were transferred to the research team by the participating supermarket. Healthiness of ready meals and pizzas was measured using a predeveloped scale based solely on the traffic light colors on the foods. Questionnaires were completed at recruitment, end of the intervention, and end of washout to estimate the effect of the intervention on variables that mediate behavior change (eg, belief and intention formation). RESULTS We recruited 496 participants from an initial email to 50,000 people. Only 3 people withdrew from the study, and purchase data were received for all other participants. A total of 208 participants completed all 3 questionnaires. There was no difference in the healthiness of purchased ready meals and pizzas between the intervention and control arms either during the intervention period (P=.32) or at washout (P=.59). CONCLUSIONS Although the FLICC study did not find evidence of an impact of the intervention on food purchasing behavior, the unique methods used in this pilot trial are informative for future studies that plan to use supermarket loyalty card data in collaboration with supermarket partners. The experience of the trial showcases the possibilities and challenges associated with the use of loyalty card data in public health research.

“…As a result of these developments, a series of barcode scanning mobile Health (mHealth) applications have been developed with the intent to display support healthy food choices, for example by displaying FoPL in absence of such regulation [6,9,31]. These apps are seen as an inclusive and scalable support system for healthy food [7].…”

The rise in diet-related non-communicable diseases suggests that consumers find it difficult to make healthy food-related purchases. This situation is most pertinent in fast-paced retail environments where customers are confronted with sugar-rich or savory food items. Countermeasures such as front-of-package labelling are not yet mandated in most regions, and barcode scanning mobile applications are impractical when purchasing groceries. We thus applied a mixed reality (MR) wearable headset-mediated intervention (N = 61) at vending machines to explore the potential of passively activated, pervasive MR food labels in affecting beverage purchasing choices. Through conduction of a betweensubject randomized controlled trial, we find significant, strong improvements in nutritional quality of the selected products (Energy:-34% KJ/100ml, Sugar:-28% g/100ml). Our post-hoc analysis suggests that the intervention effect is especially effective with existing food literacy. This study motivates further research on MR food labels due to the promising, observed intervention effects.

Cardiovascular disease is one of the main health problems and causes of death in the world. M-Health (mobile health) has the potential to improve the prevention of disease recurrence by providing continuous intervention after treatment at a hospital. The purpose of this paper were to review health literature that examines the application of m-health as a preventive measure in cardiovascular disease patients, identify features contained in m-health applications and analyze the factors for implementing mobile health. The preparation of this literature review used various databases including EBSCO, Google Scholar, Science Direct, PubMed, and Sage Journal which was conducted from December 2018 to January 2019. In total, this paper used 6 journals reviewed with predetermined keywords: four journals with quantitative methods, one journal with qualitative methods, and one journal with mixed-methods feasibility. Then screening was done based on the specified inclusion and exclusion criteria. M-health can change healthy behavior post-treatment at a hospital and prevent recurrence in patients with cardiovascular disease, With remote health services health workers can easily monitor patients' health status. The factors that influence the application of m-health are the level of patient knowledge of technology, the level of awareness of prevention of cardiovascular disease, lack of motivation for smartphone use, and poor internet access in a remote area.
