Abstract：
Policy, systems, and environmental (PSE) approaches can facilitate physical activity in priority populations (e.g., racial and ethnic minority, low wealth groups) within early childhood education (ECE) settings. The purpose of this review was to 1) characterize the inclusion of priority populations within ECE physical activity interventions containing PSE approaches and 2) identify and describe interventions within these populations. Seven databases were systematically searched (January 2000-Febrary 2022) for ECE-based interventions focusing on children (0-6 years) that utilized at least one PSE approach. Eligible studies included a child physical activity or physical activity environment outcome and child or center-level population characteristics. Forty-four studies, representing 42 interventions were identified. For Aim 1, half of interventions included one PSE approach (21/42), with only 11/42 including three or more approaches. Physical environment changes [e.g., adding play equipment, modifying space (25/42)] were the most used PSE approaches followed by system [e.g., integrating activity into routines, (21/42)] and policy [e.g., outdoor time (20/42)] approaches. Nearly half of interventions were conducted in predominantly priority populations (18/42). Studies were primarily rated as good (51%) or fair (38%) methodological quality using the Downs and Black checklist. In Aim 2, of the 12 interventions assessing child physical activity in priority populations, 9/12 reported at least one physical activity outcome in the expected direction. Of the 11 interventions assessing the physical activity environment, 9/11 reported an effect in the expected direction. Findings indicate clear opportunities exist to target priority populations by incorporating PSE approaches in ECE physical activity interventions.
摘要：
政策，系统,和环境(PSE)方法可以促进优先人群的身体活动(例如，种族和少数族裔，低财富群体)在幼儿教育(ECE)环境中。这项审查的目的是1）描述将优先人群纳入包含PSE方法的ECE身体活动干预措施中的特征，以及2）确定和描述这些人群中的干预措施。系统地搜索了七个数据库（2000年1月至2022年2月），以获得基于欧洲经委会的干预措施，重点是使用至少一种PSE方法的儿童（0-6岁）。符合条件的研究包括儿童身体活动或身体活动环境结果以及儿童或中心水平的人群特征。44项研究,代表42项干预措施被确定。对于目标1，一半的干预措施包括一种PSE方法(21/42)，只有11/42包括三个或更多的方法。物理环境变化[例如，添加游戏设备，修改空间(25/42)]是最常用的PSE方法，其次是系统[例如，将活动整合到例程中，(21/42)]和政策[例如，室外时间（20/42）]接近。近一半的干预措施主要在优先人群中进行(18/42)。使用Downs和Black检查表，研究主要被评为良好（51％）或一般（38％）的方法学质量。在目标2中，在评估优先人群儿童体力活动的12项干预措施中，9/12报告了至少一个预期方向的身体活动结果。在评估身体活动环境的11项干预措施中，9/11报告了预期方向的影响。调查结果表明，通过将PSE方法纳入欧洲经委会的身体活动干预措施，存在针对优先人群的明确机会。
