Availability and affordability of healthy and less healthy food in Nova Scotia: where you shop may affect the availability and price of healthy food.

Abstract

The present study aimed to examine the availability and price of healthier compared with less healthy foods by geography, store category and store type for convenience stores, and by store size for grocery stores in Nova Scotia. A cross-sectional study that examined differences in the overall availability and price of healthier compared to less healthy foods in grocery and convenience stores in Nova Scotia. The Nova Scotia Consumer Food Environment project was part of a larger initiative of the Nova Scotia government (Department of Health and Wellness) to assess the food and beverage environment in Nova Scotia in 2015/16. Four geographic zones (Nova Scotia Health Authority Management Zones) in Nova Scotia, Canada. A sample of forty-seven grocery stores and fifty-nine convenience stores were selected from a list of 210 grocery stores and 758 convenience stores in Nova Scotia to ensure geographic and store type representation in our sample. Findings indicate that rurality had a significant effect on food availability as measured by the Nutrition Environment Measures Surveys (NEMS) score (P < 0·01); there was a higher availability of healthy foods in rural compared to urban areas for convenience stores but not grocery stores. Healthier foods were also more available in chain stores compared to independent stores (P < 0·01) and in large stores compared to small and medium stores (P < 0·001 and P < 0·01, respectively). The availability of and accessibility to less healthy foods in Nova Scotia food environment suggests that there is a need for government policy action to support a food environment that contributes to healthier diets.
