Abstract

BACKGROUND

Much evidence-based physical activity (PA) interventions have been tested and implemented in urban contexts. However, studies that adapt, implement, and evaluate the effectiveness of these interventions in micropolitan rural contexts are needed. The study aimed to evaluate the effectiveness of the Active Ottumwa intervention to promote PA in a micropolitan community.

METHODS

Between 2013 - 2019, we implemented Active Ottumwa in a micropolitan setting, and subsequently implemented and evaluated its effectiveness using a Hybrid Type I design. In this paper, we describe the intervention's effectiveness in promoting PA. We collected PA data over 24 months from a cohort of community residents using accelerometers and PA data from two cross-sectional community surveys administered in 2013 and 2018, using the Global Physical Activity Questionnaire.

RESULTS

From the cohort, we found significant change in PA over 24 months (P = 0.03) corresponding to a 45-min daily decrease in sedentary activity, a daily increase of 35-min in light PA and 9 min in moderate-to-vigorous PA. There was a statistically significant (P = 0.01) increasing trend at the population-level in the moderate-to-vigorous composition of 7 min between the two cross-sectional assessments (95% CI: 0.1%-1.34%).

CONCLUSIONS

The study demonstrates that the adapted evidence-based PA interventions in a micropolitan context is effective.

摘要

背景

已经有大量基于证据的身体活动 (PA) 干预措施在城市环境中进行了测试和实施。然而，需要在城乡结合部的农村微中心环境中进行这些干预措施的适应、实施和有效性评估的研究。本研究旨在评估 Active Ottumwa 干预措施在一个微中心社区促进身体活动的有效性。

方法

2013 年至 2019 年，我们在一个城乡结合部实施了 Active Ottumwa 项目，并随后采用混合型 I 设计实施和评估其效果。在本文中，我们描述了干预措施在促进身体活动方面的有效性。我们使用加速度计从社区居民的队列中收集了 24 个月的身体活动数据，并使用全球身体活动问卷从 2013 年和 2018 年进行的两次横断面社区调查中收集了身体活动数据。

结果

从队列中，我们发现 24 个月的身体活动有显著变化（P=0.03），对应于久坐活动每天减少 45 分钟，轻度活动每天增加 35 分钟，中度到剧烈活动每天增加 9 分钟。在两个横断面评估之间，中等至剧烈活动的组成部分有统计学意义的（P=0.01）增加趋势，增加了 7 分钟（95%CI：0.1%-1.34%）。
