Click & Pick Study: Healthy Food Policies in Online Stores

This study, called the "Click & Pick Study," is looking at how different healthy food policies in online grocery stores and restaurants can help people make healthier food choices. Researchers want to see if things like taxes on unhealthy ultra-processed foods, nutrition labels on the front of food packages, and rules that limit how unhealthy foods are promoted at checkout can encourage people to buy and eat more healthy foods and fewer unhealthy ones. You might be able to join if you are 18 or older, meet certain income requirements, and do not currently receive SNAP benefits. The study will measure how many calories you buy from unhealthy ultra-processed foods over several weeks to see if these policies make a difference. The current recruitment status is unclear.

Study design
This study is interventional and plans to enroll 300 participants. You would be randomly assigned to either a group with no policies or a group with a suite of healthy food policies in online stores.
What's involved
You would shop once per week for six weeks in both an online grocery store and restaurant. The first week is a baseline, followed by three weeks with interventions, and two weeks with unhealthy food marketing.
Compensation
Not stated in the trial record.
Follow-up
The primary measurements for this study are taken between baseline and Weeks 2-4, and again between baseline and Weeks 5-6.

What this trial measures

  • Average kcals purchased per participant per day from unhealthy ultra-processed food products that are targeted by our suite of healthy food policiesChange between baseline and Weeks 2-4 (Aim 1) and Weeks 5-6 (Aim 3)

    We will sum the number of kcals from ultra-processed food products purchased in the online grocery store and divide that by the number of people in the household and 7 days per week. We will then add that to the number of kcals from ultra-processed foods purchased from the online restaurant to calculate total kcals from ultra-processed foods purchased per study participant per day. We will also examine these outcomes separately in the grocery store and restaurant context.
