Ecological models are currently the most used approaches to classify and conceptualise determinants of sedentary behaviour, but these approaches are limited in their ability to capture the complexity of and interplay between determinants. The aim of the project described here was to develop a transdisciplinary dynamic framework, grounded in a system-based approach, for research on determinants of sedentary behaviour across the life span and intervention and policy planning and evaluation.
A comprehensive concept mapping approach was used to develop the Systems Of Sedentary behaviours (SOS) framework, involving four main phases: (1) preparation, (2) generation of statements, (3) structuring (sorting and ranking), and (4) analysis and interpretation. The first two phases were undertaken between December 2013 and February 2015 by the DEDIPAC KH team (DEterminants of DIet and Physical Activity Knowledge Hub). The last two phases were completed during a two-day consensus meeting in June 2015.
During the first phase, 550 factors regarding sedentary behaviour were listed across three age groups (i.e., youths, adults and older adults), which were reduced to a final list of 190 life course factors in phase 2 used during the consensus meeting. In total, 69 international delegates, seven invited experts and one concept mapping consultant attended the consensus meeting. The final framework obtained during that meeting consisted of six clusters of determinants: Physical Health and Wellbeing (71% consensus), Social and Cultural Context (59% consensus), Built and Natural Environment (65% consensus), Psychology and Behaviour (80% consensus), Politics and Economics (78% consensus), and Institutional and Home Settings (78% consensus). Conducting studies on Institutional Settings was ranked as the first research priority. The view that this framework captures a system-based map of determinants of sedentary behaviour was expressed by 89% of the participants.
Through an international transdisciplinary consensus process, the SOS framework was developed for the determinants of sedentary behaviour through the life course. Investigating the influence of Institutional and Home Settings was deemed to be the most important area of research to focus on at present and potentially the most modifiable. The SOS framework can be used as an important tool to prioritise future research and to develop policies to reduce sedentary time.
生态模型是目前用于对久坐行为的决定因素进行分类和概念化的最常用方法，但这些方法在捕捉决定因素的复杂性及其相互作用方面能力有限。本文所述项目的目的是基于系统方法，开发一个跨学科动态框架，用于研究全生命周期久坐行为的决定因素以及干预措施、政策规划与评估。
采用全面的概念映射方法来构建久坐行为系统（SOS）框架，包括四个主要阶段：（1）准备阶段，（2）陈述生成阶段，（3）结构化阶段（排序和排名），以及（4）分析与解释阶段。前两个阶段由DEDIPAC KH团队（饮食与身体活动决定因素知识中心）在2013年12月至2015年2月期间完成。后两个阶段在2015年6月举行为期两天的共识会议期间完成。
在第一阶段，列出了三个年龄组（即青少年、成年人和老年人）中与久坐行为相关的550个因素，在共识会议期间使用的第二阶段中，这些因素被缩减为最终的190个生命历程因素清单。共有69名国际代表、7名受邀专家和1名概念映射顾问参加了共识会议。在该会议上获得的最终框架由六类决定因素组成：身体健康与幸福（共识率71%）、社会与文化背景（共识率59%）、建成环境与自然环境（共识率65%）、心理与行为（共识率80%）、政治与经济（共识率78%）以及机构与家庭环境（共识率78%）。对机构环境进行研究被列为首要研究重点。89%的参与者表示，该框架描绘了一个基于系统的久坐行为决定因素图谱。
通过国际跨学科共识过程，开发了SOS框架，用于研究全生命周期久坐行为的决定因素。目前，研究机构与家庭环境的影响被认为是最重要的研究领域，并且可能是最具可改变性的。SOS框架可作为一个重要工具，用于确定未来研究的优先事项，并制定减少久坐时间的政策。
