IDEFICS recommends 11 hours or more sleep for pre-school children and 10 hours for school children (6-10 years). Promotion of sufficient sleep should be part of any health-related recommendations.
A small intervention effect was seen on weeknight sleep duration in that the decrease in sleep duration over 2 years was smaller in the intervention (15 min.) as compared with control regions (19 min). There was no overall intervention effect on weekend sleep duration or on the presence of a TV in the bedroom. A small significant time effect between baseline and follow-up was found on bedroom TV presence depending on self-reported intervention exposure. Children without a TV in the bedroom had longer nocturnal sleep duration.
