Abstract

Objectives

Rural populations bear a disproportionate burden of diet-related risk, and one important explanation is retail food access disparities. Much existing literature has focused on subjective measures of the rural retail food environment, as well as urban-rural differences. The purpose of this paper is to examine how objectively measured food availability and prices vary within a rural region, and to explore how store features predict rural food availability and prices.

Methods

We conducted an observational audit of a census of rural food stores (n = 78) using a modified Nutrition Environment Measures Survey instrument. The study was conducted on the Avalon Peninsula in Newfoundland and Labrador. Observed prices in-store were matched to nutrient composition data and converted to three units of measure for all analyses: unit price ($/kg), serving price ($/serving), and energy price ($/kcal). We examined average availability and prices across the region, and how store features were associated with prices.

Results

Healthy food options were generally less available across the stores than regular items. However, with few exceptions, there were no clear or consistent patterns of difference in availability or pricing between stores of different types. No single product category stood out in terms of a clear price pattern. Store characteristics (including store type, size, ownership, or rurality) did not predict food prices.

Conclusions

Food availability and prices varied in this rural region, but with limited differences between stores of different types. More research is needed on measuring rural environmental determinants of diet in Canada.

Résumé

Objectifs

Les populations rurales supportent un fardeau disproportionné de risques liés au régime alimentaire, ce qui s’explique entre autres par les disparités d’accès aux magasins d’alimentation au détail. Une grande partie des articles scientifiques porte cependant sur les indicateurs subjectifs de l’environnement alimentaire au détail en zone rurale et sur les différences entre zones urbaines et rurales. Nous avons cherché à examiner objectivement les variations dans la disponibilité et les prix des aliments dans une région rurale et à déterminer si les caractéristiques des magasins prédisent la disponibilité et les prix des aliments en zone rurale.

Méthode

Nous avons mené un audit d’observation des magasins d’alimentation recensés dans une zone rurale (n = 78) à l’aide de l’instrument Nutrition Environment Measures Survey modifié. L’étude a été menée sur la presqu’île Avalon à Terre-Neuve-et-Labrador. Les prix observés en magasin ont été assortis à la teneur en éléments nutritifs et convertis en trois unités de mesure pour toutes nos analyses : le prix de vente unitaire ($/kg), le prix par portion ($/portion) et le prix énergétique ($/kcal). Nous avons examiné la disponibilité et les prix moyens dans la région et les associations entre les caractéristiques des magasins et les prix.

Résultats

Les aliments sains étaient généralement moins disponibles en magasin que les denrées alimentaires ordinaires. Par contre, à quelques exceptions près, nous n’avons pas observé de schémas de différence clairs ou systématiques entre différents types de magasins, que ce soit dans la disponibilité ou dans les prix des aliments. Aucune catégorie de produits ne s’est démarquée en affichant une tendance claire pour les prix. Les caractéristiques des magasins (type, taille, propriété ou ruralité) n’ont pas permis de prédire les prix des aliments.

Conclusions

La disponibilité et les prix des aliments variaient dans cette région rurale, mais les différences selon le type de magasins étaient limitées. Il faudrait pousser la recherche pour mesurer les déterminants du régime liés à l’environnement rural au Canada.
