The association of dimensions of fruit and vegetable access in the retail food environment with consumption; a systematic review.

ABSTRACT: The consumption of fruit and vegetables (F&V) is important for human health to protect against non-communicable disease and micronutrient deficiency. Increasing consumption of F&V may also benefit planetary health if these foods are substituted for foods with higher environmental footprints such as red meat or dairy. The retail food environment (RFE) is an influential junction between the food system and individual diets as it drives access to F&V through external (physical access) and personal (availability, affordability, acceptability) domains. We performed a systematic search of six literature databases (January 2021) for studies assessing access to F&V in the RFE and its association with F&V consumption in adults in high- and upper-middle income countries. 36 studies were identified and categorised by dimensions of food access - accessibility, affordability, acceptability, availability and accommodation. More than half of the studies (n = 20) were based in the USA. F&V accessibility was the most commonly reported dimension (n = 29); no study reported on accommodation. 6 studies were rated to be high quality. A positive association of increased availability of F&V options in the RFE with intake was identified in 9 of 15 studies. Associations in both acceptability and accessibility dimensions were inconsistent. No association was observed between F&V affordability and consumption although available data were limited. Many challenges exist to building a robust evidence base within food environment research including conceptual, definitional and methodological heterogeneity and measurement standardisation. Future food policies should consider multi-dimensional interventions to promote access to F&V in the RFE across all domains.

Project description:Outside of western countries, the study of the local food environment and evidence for its association with dietary behavior is limited. The aim of this paper was to examine the association between the local retail food environment and consumption of fruit and vegetables (FV) among adults in Hong Kong. Local retail food environment was measured by density of different types of retail food outlets (grocery stores, convenience stores, and fast food restaurants) within a 1000 m Euclidean buffer around individual's homes using a geographic information system (GIS). The Retail Food Environment Index (RFEI) was calculated based on the relative density of fast-food restaurants and convenience stores to grocery stores. Logistic regressions were performed to examine associations using cross-sectional data of 1977 adults (18 years or older). Overall, people living in an area with the highest RFEI (Q4, >5.76) had significantly greater odds of infrequent FV consumption (<7 days/week) after covariates adjustment (infrequent fruit consumption: OR = 1.36, 95% CI 1.04?1.78; infrequent vegetable consumption: OR = 1.72, 95% CI 1.11?2.68) in comparison to the lowest RFEI (Q1, <2.25). Highest density of fast food restaurants (Q4, >53) was also significantly associated with greater odds of infrequent fruit consumption (<7 days/week) (unadjusted model: OR = 1.34, 95% CI 1.04?1.73), relative to lowest density of fast food restaurants (Q1, <13). No significant association of density of grocery stores or convenience stores was observed with infrequent FV consumption regardless of the covariates included in the model. Our results suggest that the ratio of fast-food restaurants and convenience stores to grocery stores near people's home is an important environmental factor in meeting fruit and vegetable consumption guidelines. "Food swamps" (areas with an abundance of unhealthy foods) rather than "food deserts" (areas where there is limited access to healthy foods) seems to be more of a problem in Hong Kong's urban areas. We advanced international literature by providing evidence in a non-western setting.
