We provide an overview of a recently published, edited book in a rapidly emerging field of research, policy, and practice for physical activity: Sedentary Behavior and Health. In this commentary, we highlight the broad perspectives provided in the 27 chapters of Sedentary Behavior and Health and suggest a research strategy to move the field forward-not only with scientific rigor, but also with breadth of scholarship. The book's chapters provide an overview of the background to and contexts for sedentary behavior and health. They then highlight the importance of understanding health consequences and underlying mechanisms; introduce key measurement technology and analytic strategies; consider sedentary behavior in subpopulations; describe conceptual models and theories to guide sedentary behavior interventions; and explain what is known about interventions in different settings. Considering the breadth of perspectives brought to bear on the field and the plethora of opportunities for research, policy, and practice, we suggest 3 elements of an interdisciplinary research strategy drawing upon the primary knowledge bases of physical activity and health: through the experimental methods of exercise science, through the observational tools of epidemiology, and through the conceptual approaches and methods of behavioral science. A better understanding of the health consequences of sedentary behavior and how they may be influenced can be encompassed by 3 key questions: What changes are needed to most effectively influence sedentary behaviors? What elements of sedentary behavior should be changed to improve health outcomes? What are the feasibility of and the benefits from changing sedentary behavior?
我们概述了一本最近出版的、关于身体活动研究、政策和实践这一迅速兴起领域的编著书籍：《久坐行为与健康》。在这篇评论中，我们强调了《久坐行为与健康》27章中所提供的广泛观点，并提出了一个推动该领域向前发展的研究策略——不仅要有科学严谨性，还要有学术广度。该书各章概述了久坐行为与健康的背景和相关情况。接着，它们强调了理解健康后果及潜在机制的重要性；介绍了关键的测量技术和分析策略；探讨了亚人群中的久坐行为；描述了指导久坐行为干预的概念模型和理论；并阐述了在不同环境下已知的干预措施。考虑到该领域所涉及的广泛观点以及研究、政策和实践的众多机会，我们基于身体活动与健康的主要知识基础，提出了跨学科研究策略的三个要素：通过运动科学的实验方法、通过流行病学的观察工具以及通过行为科学的概念方法和手段。对久坐行为的健康后果以及这些后果可能如何受到影响的更好理解，可以涵盖三个关键问题：为最有效地影响久坐行为需要做出哪些改变？应该改变久坐行为的哪些要素以改善健康结果？改变久坐行为的可行性和益处是什么？
