Over the last decade, sedentary behaviors have emerged as a distinctive behavioral paradigm with deleterious effects on health independent of physical activity. The next phase of research is to establish dose response between sedentary behaviors and health outcomes and improve understanding of context and determinants of these behaviors. Establishing a common taxonomy of these behaviors is a necessary step in this process.
The Sedentary behavior International Taxonomy project was developed to establish a classification of sedentary behaviors by use of a formal consensus process.
The study follows a Delphi process in three Rounds. A preparatory stage informed the development of terms of reference documents. In Round 1, experts were asked to make statements about the taxonomy; 1) its purpose and use ; 2) the domains, categories or facets that should be consider and include; 3) the structure/architecture to arrange and link these domains and facets. In Round 2 experts will be presented with a draft taxonomy emerging from Round 1 and invited to comment and propose alterations. The taxonomy will then be finalised at the outset of this stage.
Results of Round 1 are reported here. There is a general consensus that a taxonomy will help advances in research by facilitating systematic and standardised: 1) investigation and analysis; 2) reporting and communication; 3) data pooling, comparison and meta-analysis; 4) development of measurement tools; 4) data descriptions, leading to higher quality in data querying and facilitate discoveries. There is also a consensus that such a taxonomy should be flexible to accommodate diverse purposes of use, and future advances in the field and yet provide a cross-disciplinary common language. A consensual taxonomy structure emerged with nine primary facets (Purpose, Environment, Posture, Social, Measurement, Associated behavior, Status, Time, Type) and the draft structure presented here for Round 2.
在过去十年中，久坐行为已成为一种独特的行为模式，对健康产生有害影响，且与体育活动无关。下一阶段的研究是确定久坐行为与健康结果之间的剂量反应，并加深对这些行为的背景和决定因素的理解。建立这些行为的通用分类法是这一过程中的必要步骤。
久坐行为国际分类项目旨在通过正式的共识过程建立久坐行为的分类。
该研究采用三轮德尔菲法。准备阶段为职权范围文件的制定提供了信息。在第一轮中，要求专家就分类法发表声明；1）其目的和用途；2）应考虑和纳入的领域、类别或方面；3）安排和链接这些领域及方面的结构/架构。在第二轮中，将向专家展示从第一轮中产生的分类法草案，并邀请他们发表评论并提出修改建议。然后在该阶段开始时确定分类法。
这里报告第一轮的结果。普遍共识是，分类法将通过促进系统和标准化来推动研究进展：1）调查与分析；2）报告与交流；3）数据汇总、比较和荟萃分析；4）测量工具的开发；4）数据描述，从而提高数据查询的质量并促进发现。还有一种共识是，这样的分类法应具有灵活性，以适应不同的使用目的、该领域未来的进展，同时提供一种跨学科的通用语言。出现了一个具有九个主要方面（目的、环境、姿势、社交、测量、相关行为、状态、时间、类型）的共识分类法结构，并在此展示了第二轮的草案结构。
