Objectives: Food insecurity is inadequate or insecure access to food due to financial constraints. Individuals experiencing food insecurity tend to have poorer diet quality compared to their food secure peers. Given the importance of maintaining healthful dietary patterns for optimal glycemic control, food insecurity is a considerable barrier to managing type 2 diabetes (T2DM). Healthy food prescription incentive programs aim to reduce such barriers by providing financial incentives to purchase healthy foods.

The purpose of this study is to conduct longitudinal qualitative shop-along interviews among adults with T2DM who are experiencing food insecurity. We will explore experiences of redeeming healthy food incentives and factors influencing food purchasing patterns during participation in a healthy food prescription program in Alberta, Canada.

Methods: The healthy food prescription incentive program consists of two core elements: 1) A one-time healthy food prescription pamphlet outlining an evidence-based healthy dietary pattern; and 2) A healthy food incentive of $1.50/day/household member to purchase healthy foods in participating supermarkets for 6 months.

Thirty participants aged 18-85 years will be purposefully recruited from primary care clinics. At baseline and 6-month follow-up, participants will take part in supermarket-based shop-along qualitative interviews. Participants will be asked to complete a usual grocery shop alongside a researcher. Using think-aloud principles, they will be asked to verbalize their thought processes for the shop’s duration. Researchers will also collect naturalistic observations of participants, such as consulting nutrition labels. A post-shop interview will be completed to discuss experiences, decision-making rationale, and potential barriers and facilitators to food purchasing. Data will be analyzed iteratively and inductively at each time point. Further, a longitudinal analysis will compare emerging themes and identify changes occurring over time.

Results: N/A

Conclusions: This study will generate key data regarding if, how, and why such programs may address barriers to maintaining healthful dietary patterns. These findings will help to understand experiences of participating in healthy food incentive programs that can be used to improve future programs.
