The SOS-framework (Systems of Sedentary behaviours): an international transdisciplinary consensus framework for the study of determinants, research priorities and policy on sedentary behaviour across the life course

Abstract<br/>Background: Ecological models are currently the most used approaches to classify and conceptualise determinants<br/>of sedentary behaviour, but these approaches are limited in their ability to capture the complexity of and interplay<br/>between determinants. The aim of the project described here was to develop a transdisciplinary dynamic framework,<br/>grounded in a system-based approach, for research on determinants of sedentary behaviour across the life span and<br/>intervention and policy planning and evaluation.<br/>Methods: A comprehensive concept mapping approach was used to develop the Systems Of Sedentary behaviours<br/>(SOS) framework, involving four main phases: (1) preparation, (2) generation of statements, (3) structuring (sorting and<br/>ranking), and (4) analysis and interpretation. The first two phases were undertaken between December 2013 and<br/>February 2015 by the DEDIPAC KH team (DEterminants of DIet and Physical Activity Knowledge Hub). The last<br/>two phases were completed during a two-day consensus meeting in June 2015.
