Measure
Group 1 - Control
No intervention - participants will shop in-person as they usually would. Participants will receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients.
Group 2 - Online
Participants will utilize online grocery shopping (shopping at a local grocery store via an online platform). Participants will also receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients. Online - use of online grocery shopping platform: The Online intervention will utilize online grocery shopping (shopping at a local grocery store via online platform).
Group 3 - Default
The default intervention will augment the Online intervention, showing participants a default cart when they log into their online grocery shopping accounts. They will be told that their cart has been filled with items that conform to a diabetic diet and can be used to make recipes from the provided recipe cards, and that they can modify it as they like. Participants will also receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients. Default - use of online grocery shopping platform with default shopping carts: The Defaults intervention, will augment the Online intervention, showing participants a default cart when they log into their online grocery shopping accounts. They will be told that their cart has been filled with items that conform to a diabetic diet and can be used to make the recipes from provided recipe cards, and that they may modify their cart as they like.

Timeframe: Weeks 1-5 (testing overall main effect of study group)

Population: All randomized participants were included in the repeated measures ANOVAs assessing the overall main effect of study group. Means reported below are least squares means representing calories purchased in each group overall across the time points

Receipt data are entered into Nutritionist Pro software and used to calculate total calories purchased from target grocery stores each week. For this analysis, the weekly values were aggregated, such that the least squares means reported herein represent average calories purchased across all 5 weeks, in the context of the repeated measures ANOVA model.

PRIMARY outcome

Timeframe: At post-test (week 5)

Population: Represents those with receipt data at post-test (week 5)

Nutritional quality of grocery purchases was created using indicators adapted from Fung 2008: fruit, vegetables, nuts/legumes, whole grains, low-fat dairy, sodium, red/processed meat, carbohydrates. Quintiles were calculated for each, using the number of items from a food group or sodium \[mg\] and carbohydrates \[g\] purchased that week. Resulting scores from 1-5 indicate whether participants were lower or higher on each indicator (red meat, sodium, carbohydrates reverse scored). The 8 scores were summed for a total nutritional quality score ranging from 8 to 40 (40=highest nutritional quality).

Population: All randomized participants analyzed in repeated measures ANOVA. Results reflect the average nutritional quality of purchases across all 5 study weeks (week 1-5) by group.

Nutritional quality of grocery purchases was created using indicators adapted from Fung 2008: fruit, vegetables, nuts/legumes, whole grains, low-fat dairy, sodium, red/processed meat, carbohydrates. Quintiles were calculated for each, using the number of items from a food group or sodium \[mg\] and carbohydrates \[g\] purchased that week. Resulting scores from 1-5 indicate whether participants were lower or higher on each indicator (red meat, sodium, carbohydrates reverse scored). The 8 scores were summed for a total nutritional quality score ranging from 8 to 40 (40=highest nutritional quality).

Measure
Group 1 - Control
n=21 Participants
No intervention - participants will shop in-person as they usually would. Participants will receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients.
Group 2 - Online
n=21 Participants
Participants will utilize online grocery shopping (shopping at a local grocery store via an online platform). Participants will also receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients. Online - use of online grocery shopping platform: The Online intervention will utilize online grocery shopping (shopping at a local grocery store via online platform).
Group 3 - Default
n=23 Participants
The default intervention will augment the Online intervention, showing participants a default cart when they log into their online grocery shopping accounts. They will be told that their cart has been filled with items that conform to a diabetic diet and can be used to make recipes from the provided recipe cards, and that they can modify it as they like. Participants will also receive recipe cards that follow the evidence-based DASH diet and correspond to dietary recommendations for diabetic patients. Default - use of online grocery shopping platform with default shopping carts: The Defaults intervention, will augment the Online intervention, showing participants a default cart when they log into their online grocery shopping accounts. They will be told that their cart has been filled with items that conform to a diabetic diet and can be used to make the recipes from provided recipe cards, and that they may modify their cart as they like.

SECONDARY outcome

Timeframe: At post-test (week 5)

Population: The total sample size of participants with usable food frequency questionnaire is 55 out of the 65 randomized participants. The outcome data provided is from the final intake model; least squares means are provided for each study group after adjusting for two covariates that warranted inclusion in the model, participant gender and income.

Nutritional quality of grocery purchases was created from food frequency questionnaire data using indicators adapted from Fung 2008: fruit, vegetables, nuts/legumes, whole grains, low-fat dairy, sodium, red/processed meat, carbohydrates. Quintiles were calculated for each, using reports of the frequency that the food group or nutrient of interest was consumed over the past month. Resulting scores from 1-5 indicate whether participants were lower or higher on each indicator (red meat, sodium, carbohydrates reverse scored). The 8 scores were summed for a total nutritional quality score ranging from 8 to 40 (40=highest nutritional quality).
