Ebru Sönmez Sari, Handan Terzi, Didem Şahin
PMID 39402902WHAT IT FOUND
Adolescent girls who used the internet two hours or more daily had higher social media addiction and lower physical activity attitude scores.
Those who saw themselves as inactive also showed the same pattern.
Key findings
01Higher social media addiction was significantly associated with lower cognitive-behavioral physical activity among adolescent girls (r = -0.345, p < 0.001).
02Girls who used the internet 2 hours or more daily had higher social media addiction and lower cognitive-behavioral physical activity levels than girls who used it less than 2 hours daily.
03Girls who perceived themselves as physically inactive had higher social media addiction and lower cognitive-behavioral physical activity levels than girls who perceived themselves as moderately active.

What it does not show
The study was cross-sectional, so it cannot show that social media addiction causes physical inactivity or that one leads to the other. All information came from adolescent girls' self-reports, which can be affected by memory and wanting to answer in a socially acceptable way. The sample came from one vocational high school in a single region of Türkiye, so it may not apply to adolescent girls in other places or school types. Of 403 recruited girls, 333 were analysed, and the paper does not say whether non-participants differed from participants.
The easy way to misread this
Do not conclude that social media addiction causes physical inactivity, or that reducing screen time will increase activity. This was a one-time self-report survey of adolescent girls, not a test of an intervention.
