It seems that more recent versions of npm now produce:
I rely on my Linux (Ubuntu) package manager to make decisions about when to update node and npm. Is there a way to turn this check off?
npm config ls -l

To disable notifier just run:
npm config set update-notifier false
As Dem Pilafian mentioned - it will add update-notifier=false
to ~/.npmrc
To see the current value you need this line
npm config get update-notifier
