The DREAM study

Researcher profiles:

Diet, Rest, Eating and Activity Monitoring

The DREAM study focuses on the relationship between sleep, nutrition, obesity risk and exercise in children aged 8-12 years.

One in three New Zealand children are overweight or obese. While diet and physical activity have traditionally been the focus of obesity research, it is now clear that inadequate sleep is a strong independent risk factor for obesity in children.


Does not getting enough sleep change what children eat or how active they are?

The DREAM study is a trial investigating changed sleep patterns in children. The researchers will assess whether and how not getting enough sleep changes what children eat and how they behave.

The researchers will follow children for several weeks, including one week to understand normal sleeping behaviour and two weeks of sleep intervention. During the sleep intervention there is one week that the children will be asked to go to bed an hour earlier than normal, and one week that the children will be asked to go to bed later than usual.

Some careful measurements will be done to help us understand whether being tired really does affect what children eat and how active they are.
