Evidence on what strategies - or combination of are most effective and equitable in promoting healthier diets is needed. This study examined the efficacy nudging pricing increasing healthy food purchases potential differential effect by socio-economic position (SEP) among Dutch adults a virtual supermarket.
Context-specific interventions may contribute to sustained behaviour change and improved health outcomes. We evaluated the real-world effects of supermarket nudging pricing strategies mobile physical activity coaching on diet quality, food-purchasing behaviour, walking cardiometabolic risk markers.
Food prices and affordability play an important role in influencing dietary choices, which turn have implications for public health. With inflationary increases the cost-of-living UK since 2021, understanding dynamics of food becomes increasingly important. In this longitudinal study, we aimed to examine changes from 2013 2023 by group healthiness. We established a dataset spanning years 2013–2023 combining price data Consumer Price Index beverage items with nutrient databank Department...
Diet and physical activity are important determinants of energy balance, body weight chronic health conditions. Peoples' behaviour shaped by their environment. For example, the availability unhealthy takeaway food in residential neighbourhoods ability to easily walk a range local destinations (high "walkability") influence diets levels. Most existing evidence on associations between neighbourhood adiposity is cross-sectional examines either walkability or availability, but not both...
As online food delivery service (OFDS) platforms gain popularity, understanding their impact on diet alongside physical outlets is important for addressing suboptimal dietary quality. This study examined the independent and combined associations between outlet availability out-of-home behaviours in 2019 2022. We also explored whether are modified by availability. In this repeated cross-sectional analysis, we used British data from adult International Food Policy Study (IFPS) (n = 2912) 2022...
Objectives: Physical food outlets are increasingly offering delivery through Online Food Delivery Service (OFDS) platforms, but the scale of this expansion remains unclear due to labour-intensive process manually matching online platforms. Understanding share is important, as it impacts availability and thus potentially influences dietary behaviours. This paper demonstrates how a machine learning model can efficiently match physical outlets. We also analysed proportion listed online-only...
Background: Although previous research has demonstrated socioeconomic differences in the distribution of food outlets, no study to date examined these patterns across entire territory Great Britain (GB) over time. This provides an up-to-date repeated crosssectional analysis into changes GBs retail environment from 2011 2024 and its distribution. Methods: Coordinates all fastfood outlets supermarkets GB Ordnance Survey Points Interest data were used calculate outlet densities within small...
Initiating and maintaining a healthy lifestyle -including eating sufficient physical activity- is key for cardiometabolic health. A health-promoting environment can facilitate lifestyle, may be especially helpful to reach individuals with lower socio-economic status (SES). In the Supreme Nudge project, we will study effects of pricing nudging strategies in supermarket - one most important point-of-choice settings food choices context-specific mobile activity promotion app. This paper...
Abstract Objective This study builds on prior findings that link increased availability of takeaway food outlets in home, workplace, and commuting environments to greater consumption adiposity. Using longitudinal data, we examine associations at baseline with changes adiposity between follow‐up. Methods We analyzed data from the Fenland Study, 2005 2015 follow‐up 2020. Takeaway outlet within 1 mile participants' home workplace addresses, based 2011 local authority was assessed. Outcomes...
Nudging and salient pricing are promising strategies to promote healthy food purchases, but it is possible their effects differ across groups.To investigate in which groups nudging and/or most effectively changed product purchases resulted within-food substitutions or spillover effects.In total, 318 participants successfully completed a web-based virtual supermarket experiment the Netherlands. We conducted secondary analysis of mixed randomized consisting 5 conditions (within subject) 3 arms...
We examined whether material and psychosocial resources may explain socioeconomic differences in diet quality. Cross-sectional survey data from 1461 Dutch adults (42.5 (SD 13.7) years on average 64% female) socio-demographics, quality, factors perceptions of objective healthiness the food environment were used a structural equation model to examine mediating pathways.

The aim of this study is to describe how individuals use different food retailers and retail usage varies according socio-demographic diet-related characteristics. A cross-sectional survey among Dutch adults (N = 1784) was used. Results from the Two-step cluster analysis indicated that there were five clusters users. Use discount supermarkets, organic fast-food outlets, restaurants contributed clustering, but regular local shops whether close home or further did not. included mixed outlet...
Abstract Background Unhealthy lifestyle behaviours such as unhealthy dietary intake and insufficient physical activity (PA) tend to cluster in adults with a low socioeconomic position (SEP), putting them at high cardiometabolic disease risk. Educational approaches aiming improve show limited effect this population. Using environmental context-specific interventions may create opportunities for sustainable behaviour change. In study protocol, we describe the design of real-life supermarket...
Nudging and pricing strategies are effective in promoting healthier purchases. However, whether the effects equal across individuals with different personal characteristics is unknown. This exploratory study aimed to examine differential of nudging on food purchases individuals' levels impulsivity, price sensitivity, decision-making styles, choice motives. Data from a virtual supermarket experiment where participants were exposed five conditions (control, nudging, pricing, salient nudging)...
This area-level cross-sectional study examined online food outlet availability through the most popular delivery service platforms (OFDS) across seven European countries, and explored how this was socioeconomically distributed. Data collection of automated in England, Italy, Luxembourg, Netherlands, Portugal, Spain Switzerland. We used a geographic information system to join socio-demographic information. Median number outlets delivering OFDS highest England lowest Portugal Spain. also found...
Abstract Background Low socio-economic position is associated with consumption of lower quality diets, which may be partly explained by the cost healthier diets. Therefore, we aimed to investigate mediating role dietary costs in association between educational level and diet quality. Methods We used cross-sectional data from Dutch older adults ( N = 9399) EPIC-NL cohort. Participants provided information about their own partners’ highest attained (as proxy for position). Dietary behavior was...
The cost of food is an important driver choice and most evidence suggests that healthier diets are more costly than less healthy diets.

Abstract Background Previous studies demonstrated a relation between takeaway outlet exposure and health outcomes. Individual characteristics, such as eating behaviour traits, could make some people more susceptible to the influence of food environment. Few have investigated this topic.
