Is this trial a fit for you?

Likely a good fit

Ideal participants are parents or guardians of pediatric cancer survivors aged 2–16 who actively manage the child’s groceries and shop at specified online stores.

Probably not a fit

Families without primary grocery-shopping responsibility or those not using online grocery shopping may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study examines feasibility, acceptability, and effects of an optimal defaults grocery shopping intervention on dietary quality, energy intake, and grocery costs for families with a pediatric cancer survivor. Families shop for two weeks, then are randomized to receive either weekly recipe packets with nutrition guidance or a similar set plus additional components, while continuing grocery purchasing remotely. Outcomes include changes in nutritional quality, macronutrient intake, and added sugar, as well as parent/guardian dietary intake. The trial uses real-world grocery shopping and receipt data to assess impact in a home setting.

Why it matters

Potential benefit: If successful, families may find it easier to buy healthier foods without extra effort, potentially improving long-term health for survivors.

How similar studies have gone: Prior nutrition-purchasing nudges have shown promise, but this exact optimal defaults grocery approach in pediatric cancer survivorship is novel.
