Summary

Food insecurity is associated with an increased risk of overweight/obesity and weight-related chronic illnesses. The availability of a default option (i.e., option a consumer selects if no active choice is made) has been shown to effectively nudge consumer behavior. An online default option (i.e., prefilled grocery shopping cart) was previously shown to positively impact food selection in an online grocery shopping task.The present study provides preliminary evidence for the efficacy of an online default option in enhancing the nutritional quality of online grocery purchases in individuals with food insecurity.

Detailed description

Food insecurity is associated with an increased risk of overweight/obesity and weight-related chronic illnesses. The present study provides preliminary evidence for the efficacy of an online default option in enhancing the nutritional quality of online grocery purchases in individuals with food insecurity. In behavioral economics, the default option refers to the option a consumer selects if no active choice is made. This study aims to determine whether the use of a default prefilled online grocery shopping cart results in the purchase of healthier food items in individuals with food insecurity, compared to nutrition education. The default approach, a non-monetary intervention that manipulates choice architecture, improves food choice behaviors in individuals facing significant financial constraints. The intervention is potentially broadly scalable via online platforms. It was hypothesized that the default option effectively increases the nutritional quality of foods purchased online, compared to nutrition education. Fifty participants recruited from food pantries in New York in 2018 were randomized to: (1) review nutrition information before selecting groceries for a week using a local grocery store's online shopping and delivery service (n = 23) or (2) modify a default prefilled online shopping cart containing groceries that meet nutritional guidelines according to their personal preferences (n = 27). Primary outcome measures capture the nutritional quality of groceries purchased. Our primary nutritional outcomes include servings of whole grains fruits and vegetables, fiber, daily calories, fat, saturated fat, sodium and cholesterol content.

Interventions

Type	Name	Description
BEHAVIORAL	Default Option While Online Grocery Shopping	The "default option" is a behavioral economics construct that refers to the option a consumer selects if no active choice is made (e.g. opt-out 401K plans, which significantly increase enrollment, compared to active sign up). Participants in the default condition were presented with a prefilled online shopping cart containing groceries that met nutritional requirements based on participants' gender and age.
BEHAVIORAL	Nutrition Education	The nutrition education materials were adapted from materials currently utilized by the New York State Office of Temporary and Disability Assistance ("Eat Smart New York").
