Taking advantage of the complex and multidimensional device-measured 24-hour movement behaviour to better characterise the relationship with chronic diseases

Project Details


The MOBEDIS project aims to go beyond the unidimensional assessment of physical activity (PA) using a holistic approach to describe the 24-hour movement behaviour profiles and their relationships with some chronic diseases. From a movement perspective, a day is distributed among sleep, sedentary behaviour, and PA of all intensities. As daily time is fixed to 24 hours, movement behaviours are co-dependent, which means that a change in the time allocated to one behaviour infers an equivalent change in at least one other. Analysing this type of data requires specific adapted methods such as compositional data analyses. Most cohort studies investigating the effect of PA on health focused on time spent in of moderate-to-vigorous PA (MVPA), which only represent about 5-6 % of daily time in general populations. Consequently, the well-documented health benefits of MVPA contrast with the lack of evidence on the detrimental amount of sedentary behaviour. Furthermore, additional metrics able to capture the complex nature of the movement behaviour beyond the classical FITT (Frequency, Intensity, Time, and Type) framework are needed to better define an individual’s movement behaviour profile. Thus, the present study will analyse all movement behaviours, their accumulation pattern, their regularity and complexity, and the distribution of activity intensity. The key dimensions of the 24-hour movement behaviour profiles will be identified, and dose-response relationships will be investigated. The findings will help to identify risk or protective factors for the development of chronic diseases, and to develop personalized, evidence-based preventive measures.
