It'd be nice if they included a link or even the title of the paper being referenced here to see the methods. It's hard for me to imagine how causation could even be investigated for this. You'd need to randomly induce inflammation on purpose to study participants, which seems like something you couldn't get through an IRB, nor would anybody consent to it if you could.
Otherwise, sure, you're telling me all of the factors associated with inflammation, i.e. illness, disability, injury, sedentary life, are also associated with people spending more time on social media than they might otherwise, doesn't seem like a revelation.
