Our Sleep and Activity Special Interest Group is able to investigate areas of human sleep and sleep disorders, physical activity and inactivity. The group has a range of measures on our participants relating to sleep behaviours, sleep disorders, cranio-facial measurements (3D photography), physical activity, sedentary behaviour, and even TV watching and use of screen technology devices across different ages and generations within the Raine Study.

Key findings over the last 30 years have included:
Using information collected from the Raine Study participants, researchers found that having sleep problems from childhood to adolescence predicts behavioural difficulties later in life, and that people who participate in sports and watch TV for less than 14h/week across childhood and adolescence have better physical health in young adulthood. Researchers were also able to identify factors that influence how much physical activity and sedentary behavior people engage with, as well as different patterns of activity for each gender in young adults, which can help inform programs to improve activity patterns.
A trajectory characterized by less than 14 h/week TV viewing across childhood and adolescence predicts lower body fat in young adulthood.

Higher screen time exposure in early childhood predicts lower physical activity and higher body fat in later childhood but not in adolescence.

Two types of sleep problems trajectories from childhood to adolescence were identified and predictive behavioural difficulties in later life.

An algorithm was created and validated to temporally align Raine Study data from activity monitor and laboratory sleep study, which allows for more accurate and detailed sleep/wake detections algorithms to be developed.

Five patterns of activity were identified for each gender in young adults, which can help design targeted interventions to enhance or modulate activity patterns.

Different factors were associated with positive levels of activity in young Australian adult women and men, and interventions to increase physical activity and decrease sedentary activity in young adults need to specifically consider the life stage of young adults.
