Children's sedentary lifestyles and low physical activity levels may be countered using population-level interventions. This study examines factors influencing the use of a free community-wide physical activity access pass for grade 5 students (G5AP).
A natural experiment with longitudinal data collection. A sample of 881 children completed the 9-month follow-up survey self-reporting where they used the G5AP. Two analyses were conducted: Getis-Ord GI* geographic cluster analysis of the spatial distribution of users, and logistic regression examining the relationship between use and accessibility (informational, economic, and geographic) and mobility options, while accounting for intrapersonal and interpersonal factors.
Overall, 44.9% of children used the G5AP with clusters of high use in urban areas and low use in the suburbs. Other factors significantly related to G5AP included gender (girls), informational accessibility (active recruitment), economic accessibility (median household income), geographic accessibility (facilities within 1.6 km of home), and mobility options (access to Boys & Girls Club bus).
This study found that a diverse population of children used the G5AP. To continue being successful, community-based physical activity interventions need to ensure that the intervention increases geographic, economic, and informational accessibility and provides mobility options that are available to the target population.
儿童久坐不动的生活方式和低水平的身体活动可能会通过人群干预来对抗。本研究探讨了影响五年级学生（G5AP）使用免费社区范围内体育活动通行证的因素。
一项具有纵向数据收集的自然实验。一个 881 名儿童的样本完成了 9 个月的随访调查，报告了他们使用 G5AP 的情况。进行了两项分析：用户使用情况的空间分布的 Getis-Ord GI*地理聚类分析，以及在考虑个人和人际因素的情况下，检查使用情况与可达性（信息、经济和地理）和流动性选择之间关系的逻辑回归。
总体而言，44.9%的儿童使用了 G5AP，城市地区的使用集群较高，郊区的使用集群较低。与 G5AP 显著相关的其他因素包括性别（女孩）、信息可达性（积极招募）、经济可达性（家庭收入中位数）、地理可达性（离家 1.6 公里以内的设施）和流动性选择（获得男孩和女孩俱乐部巴士）。
本研究发现，不同人群的儿童都使用了 G5AP。为了继续取得成功，基于社区的体育活动干预措施需要确保干预措施提高地理、经济和信息可达性，并为目标人群提供可用的流动性选择。
