现在需要对影响成年人久坐行为的因素进行研究，并且必须确定行为改变干预的有效方法。影响久坐行为的策略需要得到最重要的可改变的行为决定因素的证据。然而，许多与理解久坐行为决定因素相关的现有证据来自横截面研究，这些研究的局限性在于它们只识别行为“相关因素”。“与身体活动的情况一样，需要一种特定于行为和背景的方法来理解在这些行为最普遍的不同环境中起作用的多种决定因素。为此，生态模型的久坐不动的行为进行了描述，突出的行为设置结构。主要关注的行为和背景是家庭环境中的电视观看和其他屏幕聚焦行为，长时间坐在工作场所，以及坐在汽车里的时间。需要进行研究，以澄清多层次的决定因素，延长坐着的时间，这可能会在这些不同的情况下以不同的方式运作。特别需要对干预措施的可行性和有效性进行对照试验，以减少和打破成年人在家庭、工作场所和交通环境中的久坐行为。这将是翔实的外地有证据的结果“自然实验”，如引进非坐式工作选择的职业环境或新的交通基础设施的社区。(Am J Prev Med 2011;41（2）：189-196）（C）2011年美国预防医学杂志
Research is now required on factors influencing adults' sedentary behaviors, and effective approaches to behavioral-change intervention must be identified. The strategies for influencing sedentary behavior will need to be informed by evidence on the most important modifiable behavioral determinants. However, much of the available evidence relevant to understanding the determinants of sedentary behaviors is from cross-sectional studies, which are limited in that they identify only behavioral "correlates." As is the case for physical activity, a behavior- and context-specific approach is needed to understand the multiple determinants operating in the different settings within which these behaviors are most prevalent. To this end, an ecologic model of sedentary behaviors is described, highlighting the behavior settings construct. The behaviors and contexts of primary concern are TV viewing and other screen-focused behaviors in domestic environments, prolonged sitting in the workplace, and time spent sitting in automobiles. Research is needed to clarify the multiple levels of determinants of prolonged sitting time, which are likely to operate in distinct ways in these different contexts. Controlled trials on the feasibility and efficacy of interventions to reduce and break up sedentary behaviors among adults in domestic, workplace, and transportation environments are particularly required. It would be informative for the field to have evidence on the outcomes of "natural experiments," such as the introduction of nonseated working options in occupational environments or new transportation infrastructure in communities.
