“…subsidies on healthy foods, strategies to increase access to healthy foods in remote or underserved communities) ( 8–11 ), to the authors’ knowledge no zoning or land-use regulations addressing the placing and access to healthy and unhealthy food outlets have been implemented in these countries. This may explain the observed high availability of unhealthy foods in these settings, in line with previous studies ( 67 , 68 ). In contrast, the role of planning in promoting healthy communities has been recognized in policy documents and regulations in the UK, where according to our results a higher perceived availability of healthy foods was reported ( 34 ).…”

Background Food environments play a key role in dietary behavior and vary due to different contexts, regulations, and policies. Objectives This study aimed to characterize the perceived availability of healthy and unhealthy foods in three different settings in 5 countries. Methods We analyzed data from the 2018 International Food Policy Study, a cross-sectional survey of adults (18–100 years, n = 22,824) from Australia, Canada, Mexico, the United Kingdom (UK), and the United States (US). Perceived availability of unhealthy (junk food and sugary drinks) and healthy foods (fruit or vegetables, healthy snacks, and water) in the community, workplace, and university settings were measured (i.e., not available, available for purchase, or available for free). Differences in perceived availability across countries were tested using adjusted multinomial logistic regression models. Results Across countries, unhealthy foods were perceived as highly available in all settings; in university and work settings unhealthy foods were perceived as more available than healthy foods. Australia and Canada had the highest perceived availability of unhealthy foods (range 87.5–90.6% between categories), while the UK had the highest perceived availability of fruits and vegetables for purchase (89.3%) in the community. In university and work settings, Mexico had the highest perceived availability for purchase of unhealthy foods (range 69.9–84.9%). The US and the UK had the highest perceived availability of fruits and vegetables for purchase (65.3–66.3%) or for free (21.2–22.8%) in the university. In the workplace, the UK had high perceived availability of fruits and vegetables for purchase (40.2%) or for free (18.5%), while the US had the highest perceived availability of junk food for free (17.3%). Conclusions Across countries, unhealthy foods were perceived as highly available in all settings. Variability between countries may reflect differences in policies and regulations. Results underscore the need for the continuation and improvement of policy efforts to generate healthier food environments.

“…Absolute online food outlet access was 50% greater in the most deprived postcode districts in England, compared to the least deprived, with some evidence of a dose-response association across the socioeconomic gradient. This online food outlet access may allow food to be ordered from outlets not normally accessible through other modes of order, resulting in changes in perceptions about food outlet accessibility, and how populations interact with their neighbourhood, both of which contribute to food purchasing decisions ( Cervigni et al, 2020 ). In contrast to our finding, in one city in each of Australia, the Netherlands and USA, the number of food outlets accessible through an online food delivery service was not associated with area level socioeconomic status ( Poelman et al, 2020 ).…”

Socioeconomic inequalities in food outlet access through an online food delivery service in England: A cross-sectional descriptive analysis

et al. 2021

Online food delivery services facilitate ‘online’ access to food outlets selling food prepared away-from-home. Online food outlet access has not previously been investigated in England or across an entire country. Systematic differences in online food outlet access could exacerbate existing health inequalities, which is a public health concern. However, this is not known. Across postcode districts in England (n = 2118), we identified and described the number of food outlets and unique cuisine types accessible online from the market leader (Just Eat). We investigated associations with area-level deprivation using adjusted negative binomial regression models. We also compared the number of food outlets accessible online with the number physically accessible in the neighbourhood (1600m Euclidean buffers of postcode district geographic centroids) and investigated associations with deprivation using an adjusted general linear model. For each outcome, we predicted means and 95% confidence intervals. In November 2019, 29,232 food outlets were registered to accept orders online. Overall, the median number of food outlets accessible online per postcode district was 63.5 (IQR; 16.0–156.0). For the number of food outlets accessible online as a percentage of the number accessible within the neighbourhood, the median was 63.4% (IQR; 35.6–96.5). Analysis using negative binomial regression showed that online food outlet access was highest in the most deprived postcode districts (n = 106.1; 95% CI: 91.9, 120.3). The number of food outlets accessible online as a percentage of those accessible within the neighbourhood was highest in the least deprived postcode districts (n = 86.2%; 95% CI: 78.6, 93.7). In England, online food outlet access is socioeconomically patterned. Further research is required to understand how online food outlet access is related to using online food delivery services.

“…VGI offer significant and growing potential for research (Brown & Kyttä, 2014; Goranson et al, 2013; Kolak et al, 2020; Sui & DeLyser, 2012), particularly for food environment studies (Cervigni et al, 2020; Fast & Rinner, 2018; Liu et al, 2020; Quinn & Yapa, 2016). As this geographical information is contributed by volunteers from the general public (Goodchild, 2007; Mericskay & Roche, 2011), it is a source of continuously updated data that is cost‐effective and covers large areas not restricted by administrative boundaries (Goodchild, 2007; Sullivan et al, 2009; Zhang & Zhu, 2019).…”

The obesity epidemic and inequalities in access to food are prompting increasing numbers of food environment studies, which rely on secondary data sources for mapping. This article assesses the reliability of the two main food outlet data sources in France: the volunteered geographical information (VGI) collaborative map OpenStreetMap (OSM) and the national business register Sirene. Their information on food outlets was assessed through ground-truthing in the city-region of Montpellier. Sensitivity, positive predictive value, and concordance were computed for each database.We analyzed the socio-spatial variability of these measures according to households' income level. The sensitivity of Sirene is good and that of OSM moderate, while the opposite holds for positive predictive value, and the concordance of both OSM and Sirene is fair. Sirene provides more reliable data on deprived neighborhoods and OSM on wealthy neighborhoods. Caution is recommended regarding the classifications on which they are based, the time required to update the institutional database, and socially influenced contributions to VGI.
