The study is in French, but available here: https://www.santepubliquefrance.fr/docs/bulletin-epidemiologique-hebdomadaire-14-janvier-2020-n-1 …
Even without reading it, I think table 2 says pretty much everything. The one positive result highlighted in redpic.twitter.com/dVQilu8oqh
Hard to blame the journos for this one tho, the study itself is pretty questionable. Not sure how you justify using logistic regression to analyze 25 covariates with such a small sample size
The conclusions, for example, argue that exposure to screens is a significant public health issue even though the results were negative for most markers of screen exposure? So weirdpic.twitter.com/6ssCs00o6l
Things that didn't increase risk of language disorders in children:
- more screen time
- screens in holidays, during meals, during the school day, after school etc
- having the tv on more often
- the age that kids were first exposed to screens



That being said, if my translation's correct the scientists basically said "this is an interesting association that should be studied more", which doesn't really come through in the headline!
Isn’t that a bit of a stock standard line in observational studies though?
