This study examines how the 8-week Hoosier Sport program impacts cardiovascular disease (CVD) risks by promoting physical activity (PA) among rural, low-income children. Using a human-centered participatory co-design approach, the program aimed to increase PA levels (e.g., total PA, daily steps) in at-risk children. The present study explored the feasibility of the intervention as well as physiological and psychological changes across the intervention using a hybrid type 2 design (a model that evaluates both the effectiveness of an intervention and its implementation in real-world settings). Favorable feasibility indicators like attendance, acceptability, and compliance, with a 23.3% recruitment rate and 94.3% retention rate, were observed. Moreover, participants attended over 80% of sessions across the 8 weeks. Accelerometers (AX3) tracked daily steps and total PA for 7 days before and after the intervention, revealing increased PA levels throughout. At post-intervention, notable improvements were observed in psychological factors such as autonomy, social competence, and global self-worth. This study highlights the importance of tailored PA interventions in schools, emphasizing their potential to improve PA levels among rural, low-income children.
本研究通过在农村低收入儿童中推广体育活动（PA），探讨了为期 8 周的 Hoosier Sport 计划如何降低心血管疾病（CVD）风险。该计划采用以人为中心的参与式共同设计方法，旨在提高高危儿童的 PA 水平（如总 PA、每日步数）。本研究采用混合 2 型设计（一种同时评估干预措施效果及其在真实环境中实施情况的模型），探讨了干预措施的可行性以及干预过程中的生理和心理变化。研究结果表明，该干预措施具有良好的可行性指标，如参与度、可接受性和依从性，招募率为 23.3%，保留率为 94.3%。此外，参与者在 8 周内参加了超过 80%的课程。在干预前后的 7 天内，加速度计（AX3）跟踪了每日步数和总 PA，结果显示 PA 水平有所提高。在干预后，心理因素如自主性、社会能力和整体自我价值感方面有显著改善。本研究强调了学校量身定制的 PA 干预措施的重要性，突出了其提高农村低收入儿童 PA 水平的潜力。
