Aims
ActiLaus collects data on physical activity and sedentary behavior to understand their relationship with cardiovacular diseases and mental disorders
The main objectives are to:
- Describe socio-economic correlates of physical activity
- Explore mechanisms induced by physical activity and sedentary behavior on cardiovascular diseases and mental disorders
- Identify activity behaviors and patterns which are beneficial to cardiovascular and psychic health
+3000 participants have had their activity assessed by 14-day accelerometry and questionnaires.
A description of participant selection, inclusion criteria and methods used can be found in the following manuscript:
