Neighbourhood fruit and vegetable availability and consumption: the role of small food stores in an urban environment

TLDR

Previous research has focused on supermarket access, but in‑store availability in small urban food stores may also influence dietary intake. This study aims to synthesize store access and in‑store availability data to assess their relationship with fruit and vegetable consumption. Researchers mapped household distances to food stores, measured linear shelf space for produce, surveyed 102 households in four New Orleans census tracts, and applied multivariate linear regression to evaluate associations. Greater fresh vegetable shelf space within 100 m predicted higher vegetable intake (0.35 servings per day per metre), while fruit availability showed no association and small‑store presence was only a marginal predictor, underscoring the potential role of small neighbourhood stores.

Abstract

Previous studies on the relationship of dietary intake to the neighbourhood food environment have focused on access to supermarkets, quantified by geographic distance or store concentration measures. However, in-store food availability may also be an important determinant, particularly for urban neighbourhoods with a greater concentration of small food stores. This study synthesises both types of information - store access and in-store availability - to determine their potential relationship to fruit and vegetable consumption.Residents in four census tracts were surveyed in 2001 about their fruit and vegetable intake. Household distances to food stores in these and surrounding tracts were obtained using geographical information system mapping techniques. In-store fruit and vegetable availability was measured by linear shelf space. Multivariate linear regression models were used to measure the association of these neighbourhood availability measures with consumption.Four contiguous census tracts in central-city New Orleans.A random sample of 102 households.Greater fresh vegetable availability within 100 m of a residence was a positive predictor of vegetable intake; each additional metre of shelf space was associated with 0.35 servings per day of increased intake. Fresh fruit availability was not associated with intake, although having a small food store within this same distance was a marginal predictor of fruit consumption.The findings suggest the possible importance of small neighbourhood food stores and their fresh produce availability in affecting fruit and vegetable intake.
