This study aimed to evaluate the effect of step-count monitoring interventions on objectively measured physical activity-related outcomes in children and adolescents.
This review was designed and conducted based on the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. The following five electronic databases were searched to identify relevant studies: PubMed, Web of Science, SCOPUS, SPORTDiscus, and Cochrane Library. The search was performed from the date of database inception to December 7, 2024. Meta-analyses were conducted to evaluate the pooled effects of the interventions on daily steps, accelerometer-measured moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary behavior (SB).
Thirty-four studies were selected for this meta-analysis. Step-count monitoring interventions could significantly increase daily steps (MD 1588.83 steps/day; 95% CI 1033.94 to 2143.72; < 0.01) and tended to significantly reduce SB (MD -3.42 min/day; 95% CI -6.83 to -0.01; = 0.05). However, they had no significant effects on MVPA (MD 0.59 min/day; 95% CI -3.46 to 4.64; = 0.78) and LPA (MD 1.29 min/day; 95% CI -1.44 to 4.03; = 0.35). Subgroup analyses indicated that step-count monitoring interventions offered greater benefits for increasing MVPA in children (MD 6.09 min/day; < 0.01) than in adolescents (MD -3.79 min/day; = 0.13). Pedometer-based interventions (MD 1757.58 steps/day; < 0.01) were more effective at increasing daily steps than those involving other emerging step-count monitoring devices (MD 406.12 steps/day; = 0.37).
Step-count monitoring interventions may be appropriate and effective for increasing total physical activity and reducing SB in children and adolescents. Moreover, these interventions may serve as an optional approach for increasing MVPA in children. We recommend a "less is more" strategy with regard to step-count monitoring interventions for increasing physical activity in children and adolescents.
本研究旨在评估步数监测干预措施对客观测量的儿童和青少年身体活动相关结果的影响。
本综述依据系统评价与Meta分析的首选报告项目（PRISMA）指南进行设计和实施。检索了以下五个电子数据库以识别相关研究：PubMed、科学网、Scopus、体育数据库和Cochrane图书馆。检索从数据库创建之日至2024年12月7日。进行Meta分析以评估干预措施对每日步数、加速度计测量的中度至剧烈身体活动（MVPA）、轻度身体活动（LPA）和久坐行为（SB）的综合影响。
本Meta分析选取了34项研究。步数监测干预措施可显著增加每日步数（MD 1588.83步/天；95%CI 1033.94至2143.72；P<0.01），并倾向于显著减少久坐行为（MD -3.42分钟/天；95%CI -6.83至-0.01；P = 0.05）。然而，它们对中度至剧烈身体活动（MD 0.59分钟/天；95%CI -3.46至4.64；P = 0.78）和轻度身体活动（MD 1.29分钟/天；95%CI -1.44至4.03；P = 0.35）没有显著影响。亚组分析表明，步数监测干预措施对增加儿童的中度至剧烈身体活动（MD 6.09分钟/天；P<0.01）比青少年（MD -3.79分钟/天；P = 0.13）更有益。基于计步器的干预措施（MD 1757.58步/天；P<0.01）在增加每日步数方面比涉及其他新兴步数监测设备的干预措施（MD 406.12步/天；P = 0.37）更有效。
步数监测干预措施对于增加儿童和青少年的总体身体活动以及减少久坐行为可能是合适且有效的。此外，这些干预措施可能是增加儿童中度至剧烈身体活动的一种可选方法。我们建议在儿童和青少年增加身体活动的步数监测干预方面采用“少即是多”的策略。
