Summary Food environments are directly linked to diets and health outcomes such as overweight, obesity, noncommunicable diseases. The digitalization of food is becoming a central issue in public health, yet little known about this emerging field. We performed systematic scoping review map the research on digital environment investigate how eight dimensions environment, according an established framework (availability, prices, vendor product properties, marketing regulation, accessibility, affordability, convenience, desirability), might be shifting context society. searched MEDLINE, EMBASE, Scopus, Web Science for studies published between 2000 2019, using search terms covering technology which yielded 13,580 unique records. Our analysis 357 shows that taking place all enabling emergence new forms buying selling food, online grocery shopping delivery, may changing availability foods affecting physical distance shops time allocated shopping. Systematic reviews identified indicated social media can influence choices, preferences consumption. findings suggest interconnected influencing one another, but impact nutrition unclear.

Abstract Background The current food system in England promotes a population diet that is high fat, sugar and salt (HFSS). To address this, the UK government has implemented legislation to restrict promotion of HFSS products prominent locations (e.g. store entrances, checkouts) qualifying retailers since October 2022. This study investigated perceived impact for affected stakeholders. Methods A pre-implementation rapid qualitative evaluation stakeholder interviews. One hundred eight stakeholders participated including 34 consumers, 24 manufacturers retailers, 22 local authority enforcement officers 28 academic charitable health representatives. participatory conference was used enable policy recommendations be confirmed by Results Stakeholders ‘good first step’ towards improving but recognised this needed considered amongst range long-term obesity policies. Areas further support were identified these are presented as six successful implementation legislation: (1) provide free central calculator, (2) refine enhance intent clarity, (3) conduct robust assess intended unintended outcomes, (4) greater smaller businesses, (5) ring-fenced resources authorities (6) create communicate roadmap health.

Abstract Background Poor diet is the leading preventable risk factor contributing to burden of disease globally and in Australia, inequitably distributed. As price healthy foods a perceived barrier improved diets, evidence on cost affordability current (unhealthy) recommended (healthy, more equitable sustainable) diets required support policy action. Methods This study applied Healthy Diets ASAP (Australian Standardised Affordability Pricing) methods protocol measure cost, differential for reference household Queensland, Australia. Food prices were collected 18 randomly selected locations stratified by area socioeconomic disadvantage remoteness. Diet was calculated three income categories. Results Surprisingly, would 20% less than Queensland as whole. Households spent around 60% their food budget discretionary choices (that is, those not health that are high saturated fat, added sugar, salt and/or alcohol). families need spend 23% diets. However, be affordable low or very remote areas, costing 30 35% median respectively. The government supplements due SARS-CoV-2 pandemic improve 29%. Conclusions Study findings highlight while one affecting consumer choice, other drivers such taste, convenience, advertising availability important. Nevertheless, found unaffordable low-income likely experiencing stress, irrespective where they live Queensland.

Summary Adolescence is a period of increased autonomy over decision‐making, including food choices, and exposure to influences outside the home, environment. This review aims synthesize evidence for influence community nutrition environments, spatial access outlets, consumer environments inside on adolescent purchasing dietary behaviors in high‐income countries. Six databases were searched articles published before January 2023. Results synthesized using vote‐counting technique effect direction plots that record relation anticipated relationship with health. Thirty‐four observational two intervention studies met inclusion criteria. In 13 assessing healthy results did not show clear associations outcomes. Thirty assessed adolescents' unhealthy majority (n = 17/30, 57%) reporting showing greater outlets classified as was associated less purchases intakes. Inconsistent observed across seven investigating Further research these areas, more high‐quality studies, may help develop policy strategies improve behaviors.

Abstract A global transformation of food systems is needed, given their impact on the three interconnected pandemics undernutrition, obesity and climate change. scoping review was conducted to synthesise effectiveness system policies/interventions improve nutrition, nutrition inequalities environmental sustainability, identify double- or triple-duty potentials (their tackling simultaneously two all these outcomes). When available, effects nutritional vulnerabilities women’s empowerment were described. The studied derived from a compilation international recommendations. literature search according PRISMA extension for reviews. total 196 reviews included in analysis. interventions identified sustainable agriculture practices school programmes. Labelling, reformulation, in-store nudging fiscal measures showed double-duty potential across outcomes. Labelling also incentivises reformulation by industry. Some (i.e., programmes, measures) reduce socio-economic differences diets, whereas labelling may be more effective among women higher groups. trade-off that healthy provision increase waste. Overall, multi-component found most inequalities. Policies combining sustainability objectives are few mainly information type labelling). Little evidence available policies/interventions’ effect empowerment. Current research fails provide good-quality policies/interventions, particular supply chains domain.

Background Previous product placement trials in supermarkets are limited scope and outcome data collected. This study assessed the effects on store-level sales, household-level purchasing, dietary behaviours of a healthier supermarket layout. Methods findings is prospective matched controlled cluster trial with 2 intervention components: (i) new fresh fruit vegetable sections near store entrances (replacing smaller displays at back) frozen vegetables repositioned to entrance aisle, plus (ii) removal confectionery from checkouts aisle ends opposite. In this pilot study, was implemented for 6 months 3 discount England. Three control stores were sales customer profiles neighbourhood deprivation. Women customers aged 18 45 years, loyalty cards, assigned ( n = 62) or group 88) their primary store. The registration number NCT03518151. Interrupted time series analysis showed that increases fruits greater than predicted (1.71 standard deviations (SDs) (95% CI 0.45, 2.96), P 0.01) follow-up (2.42 SDs (0.22, 4.62), 0.03), equivalent approximately 6,170 9,820 extra portions per store, week, respectively. proportion purchasing week rose among participants compared (0.2% versus −3.0%, 0.22; 1.7% −3.5%, 0.05, respectively). Store lower (−1.05 (−1.98, −0.12), 0.03) (−1.37 (−2.95, 0.22), 0.09), 1,359 1,575 fewer respectively; no differences observed purchasing. Changes variables predominantly expected direction health benefit. Intervention implementation not within research team, could be randomised. It and, therefore, powered detect an effect. Conclusions Healthier layouts can improve nutrition profile likely household quality. Placing should considered alongside policies limit prominent unhealthy foods.

Real-life experiments in supermarkets to encourage healthy dietary-related behaviours: opportunities, challenges and lessons learned

International Journal of Behavioral Nutrition and Physical Activity, Год журнала: 2023, Номер 20(1)

Опубликована: Июнь 20, 2023

Abstract Background Supermarkets are the primary source of food for many people yet their full potential as a setting to encourage healthy dietary-related behaviours remains underutilised. Sharing experiences from research groups who have worked with supermarket chains evaluate strategies that promote eating could improve efficiency building such relationships and enhance design quality future studies. Methods A collective case study approach was used synthesise engaging sustaining collaborations national test effectiveness health-focused in-store interventions. The narrative covers studies conducted in three high-income countries: Australia, Netherlands United Kingdom. Results We distilled our lessons learned into six recommendations conducting high public health commercial chains. These include: (i) using personal contacts, knowledge activities executive management establish partnership allowing time build trust; (ii) using scientifically robust designs appropriate sample size calculations; (iii) formalising data exchange arrangements allocating adequate resource extraction re-categorisation; (iv) assessing effects at individual/households level where possible; (v) designing mixed-methods process evaluation measure intervention fidelity, dose unintended consequences; (vi) ensuring scientific independence through formal contract agreements. Conclusions Our working non-financial partnerships be useful other looking develop implement an efficient manner. Further evidence real-life interventions is necessary identify sustainable can population diet maintain outcomes.
