Screenie

Screenies: these boys spent very large amounts of time in front of a screen of some sort — 10 per cent of boys spend over seven hours every day in front of a screen — but had low levels of physical activity and sleep.

The study found three clusters of boys: 'sporties', 'screenies' and 'autonomes' (the last group spending a lot of time in self-starting pursuits, either by themselves or with peers).
