Do social media 'Likes' make teens buy more junk food?
NCT ID NCT06969638
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the number of 'likes' on social media food ads influences what Black and White teenagers (ages 13-17) choose to buy. Researchers will show ads with many or few likes and featuring Black or White individuals, then ask teens to pick snacks in a hypothetical store. The goal is to see if social media popularity affects food decisions.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help understand how social media influences teens' food choices, potentially informing future public health campaigns or regulations.
- What could go wrong
- This is an observational-style behavioral study with hypothetical choices, not a real-world purchase setting. Results may not reflect actual eating habits or apply to all teens.
