背景：已经制定了促进体力活动的循证指南，但关于传播有效干预措施的信息很少。这项研究的目的是更好地了解体力活动干预措施在美国的传播情况，尤其是基于证据的指南。设计：在美国进行了一项横断面研究，围绕创新扩散理论的修改版本进行组织。背景/参与者：受访者(n=49)是每个州或地区卫生部门的体力活动联系人(例如，项目管理员、健康教育者)。主要结果衡量标准：7项与体力活动干预相关的具体计划和政策被视为因变量。另外五个领域--组织氛围、意识、采用、实施和维护--构成了一组独立变量。结果：与决策相关的最重要因素是充足资源的可用性。大多数受访者(89.8%)知道促进体力活动的循证指南。然而，只有不到一半的受访者(41%)有权实施循证方案和政策。少数受访者报告说，他们得到了州长(35.4%)或大多数州议员(21.3%)的支持。采取循证干预措施有几个关键因素，包括国家对体育活动的资助，受访者是否参加了适度的体育活动，是否有足够的工作人员，以及有一个支持性的州立法机构。结论：州和地区卫生部门对促进体育活动的重要性的认识相对较高；然而，卫生部门内部的支持水平似乎超过了来自民选官员的任何外部支持。
Background: Evidence-based guidelines for promoting physical activity have been produced, yet sparse information exists on the dissemination of effective interventions. The purpose of this study was to better understand the dissemination of physical activity interventions across the United States, focusing particularly on evidence-based guidelines.Design: A cross-sectional study was conducted in the U.S. that was organized around a modified version of the diffusion of innovations theory.Setting/Participants: Respondents (n=49) were the physical activity contact person (e.g., program administrator tor, health educator) in each state or territorial health department.Main Outcome Measures: Seven specific programs and policies relating to physical activity intervention were examined as dependent variables. Five additional domains-organizational climate, aware: ness, adoption, implementation, and maintenance-framed a set of independent variables.Results: The most important factor related to decision making was the availability of adequate resources. Most respondents (89.8%) were aware of evidence-based guidelines to promote physical activity. However, less than half of the respondents (41%) had the authority to implement evidence-based programs and policies. A minority of respondents reported having support from their state governor (35.4%) or from most of their state legislators (21.3%). Several key factors were associated with the adoption of evidence-based interventions, including the presence of state funding for physical activity, whether the respondent participated in moderate physical activity, presence of adequate staffing, and presence of a supportive state legislature.Conclusions: Awareness of the importance of promoting physical activity is relatively high in state and territorial health departments; however, the levels of internal support within the health department appear to outweigh any outside support from elected officials.
