A Default Option to Enhance Dietary Quality in Participants With Food

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
