Title of project: 
The bidirectional relationships among physical activity, sedentary behaviour, weight status and depression
Proposal summary: 

This project will evaluate how physical activity, sedentary behaviour, obesity and depression influence one another during adolescence (age 12 to 18 years). We will use data from the ALSPAC study, which has been following these adolescents since their birth in 1991-1992. This project will support practitioners, researchers and policy makers in designing effective public health interventions that target the increasing rates of obesity, depression and physical inactivity by understanding the complexity of their relationships during adolescence.

Impact of research: 
This project will support researchers and practitioners in understanding the complex relationships among sedentary behaviour, physical activity, weight status and depression during adolescence and how these relationships develop over time. For example, this project might indicate that it might be more appropriate to focus on increasing physical activity level in early adolescence or to target adiposity in middle adolescence because of the strength of the relationships that might be observed. Therefore, providing support on the best interventional approaches to target low levels of physical activity and higher rates of obesity and depression in the adolescent population.
