大多数成年人不符合体育活动的指导方针，尽管活动与许多长期健康的改善有关。有鉴于此，研究人员呼吁采取更多的社区干预措施。本研究的主要目的是评估社区一级的体育活动干预是否增加了农村社区的活动水平。在2011年4月至2012年12月的四个时间段之一，128个农村村庄（集群）被随机分配接受干预。德文郡积极村干预措施为所有年龄组的村庄提供了12周的体育活动机会，包括每个村庄至少三种不同类型的活动。每个村庄都得到了量身定制的干预措施，其中包括以当地需求为导向的办法。干预后又提供了12个月的支助。该评价研究采用了阶梯式楔形分组随机对照试验设计。所有128个村庄都在五个数据收集期的每一个期间使用邮政调查进行了测量。主要关注的结果是成年人报告足够的体力活动以满足国际公认的指南的比例。每周中等强度和剧烈活动的时间作为次要结局进行分析。为了比较干预和控制模式，随机效应线性回归和边际logistic回归模型分别实施连续和二元结果。10,412名成年人（4693名干预者，5719名对照者）完成了邮寄调查（回复率32.2%）。干预并没有增加成年人符合体力活动指南的几率（调整后OR 1.02，95% CI：0.88至1.17; P = 0.80），尽管有微弱的证据表明每周中等强度和高强度活动的分钟数增加（调整后平均差异= 171，95% CI：-16至358; P = 0.07）。干预的无效性可能是由于其渗透率低-只有16%的干预模式参与者报告了干预的意识，只有4%的参与者报告了干预事件。社区一级的体育活动干预措施为农村提供量身定制的体育活动机会，并没有提高成年人的体育活动水平。如果要在社区一级增加体育活动的普及率，就必须扩大这些干预措施的渗透。当前对照试验ISRCTN 37321160。
The majority of adults are not meeting the guidelines for physical activity despite activity being linked with numerous improvements to long-term health. In light of this, researchers have called for more community-level interventions. The main objective of the present study was to evaluate whether a community-level physical activity intervention increased the activity levels of rural communities. 128 rural villages (clusters) were randomised to receive the intervention in one of four time periods between April 2011 and December 2012. The Devon Active Villages intervention provided villages with 12 weeks of physical activity opportunities for all age groups, including at least three different types of activities per village. Each village received an individually tailored intervention, incorporating a local needs-led approach. Support was provided for a further 12 months following the intervention. The evaluation study used a stepped wedge cluster randomised controlled trial design. All 128 villages were measured at each of five data collection periods using a postal survey. The primary outcome of interest was the proportion of adults reporting sufficient physical activity to meet internationally recognised guidelines. Minutes spent in moderate-and-vigorous activity per week was analysed as a secondary outcome. To compare between intervention and control modes, random effects linear regression and marginal logistic regression models were implemented for continuous and binary outcomes respectively. 10,412 adults (4693 intervention, 5719 control) completed the postal survey (response rate 32.2%). The intervention did not increase the odds of adults meeting the physical activity guideline (adjusted OR 1.02, 95% CI: 0.88 to 1.17; P = 0.80), although there was weak evidence of an increase in minutes of moderate-and-vigorous-intensity activity per week (adjusted mean difference = 171, 95% CI: -16 to 358; P = 0.07). The ineffectiveness of the intervention may have been due to its low penetration—only 16% of intervention mode participants reported awareness of the intervention and just 4% reported participating in intervention events. A community-level physical activity intervention providing tailored physical activity opportunities to rural villages did not improve physical activity levels in adults. Greater penetration of such interventions must be achieved if they are to increase physical activity prevalence at the community level. Current Controlled Trials ISRCTN37321160.
