Studies that assess all three dimensions of the integrative 24-hour physical behaviour (PB) construct, namely, intensity, posture/activity type and biological state, are on the rise. However, reviews on validation studies that cover intensity, posture/activity type and biological state assessed via wearables are missing.
Systematic review. The risk of bias was evaluated by using the QUADAS-2 tool with nine signalling questions separated into four domains (ie, patient selection/study design, index measure, criterion measure, flow and time).
Peer-reviewed validation studies from electronic databases as well as backward and forward citation searches (1970-July 2021).
Wearable validation studies with children and adolescents (age <18 years). Required indicators: (1) study protocol must include real-life conditions; (2) validated device outcome must belong to one dimension of the 24-hour PB construct; (3) the study protocol must include a criterion measure; (4) study results must be published in peer-reviewed English language journals.
Out of 13 285 unique search results, 76 articles with 51 different wearables were included and reviewed. Most studies (68.4%) validated an intensity measure outcome such as energy expenditure, but only 15.9% of studies validated biological state outcomes, while 15.8% of studies validated posture/activity type outcomes. We identified six wearables that had been used to validate outcomes from two different dimensions and only two wearables (ie, ActiGraph GT1M and ActiGraph GT3X+) that validated outcomes from all three dimensions. The percentage of studies meeting a given quality criterion ranged from 44.7% to 92.1%. Only 18 studies were classified as 'low risk' or 'some concerns'.
Validation studies on biological state and posture/activity outcomes are rare in children and adolescents. Most studies did not meet published quality principles. Standardised protocols embedded in a validation framework are needed.

评估24小时综合身体行为（PB）结构所有三个维度（即强度、姿势/活动类型和生理状态）的研究正在增加。然而，关于通过可穿戴设备评估强度、姿势/活动类型和生理状态的验证研究的综述却缺失。
系统综述。使用QUADAS - 2工具评估偏倚风险，该工具包含九个信号问题，分为四个领域（即患者选择/研究设计、指标测量、标准测量、流程和时间）。
电子数据库中的同行评审验证研究以及向后和向前的引文检索（1970年 - 2021年7月）。
针对儿童和青少年（年龄<18岁）的可穿戴设备验证研究。所需指标：（1）研究方案必须包括现实生活条件；（2）经过验证的设备结果必须属于24小时PB结构的一个维度；（3）研究方案必须包括标准测量；（4）研究结果必须发表在同行评审的英文期刊上。
在13285个独特的搜索结果中，纳入并审查了76篇文章，涉及51种不同的可穿戴设备。大多数研究（68.4%）验证了强度测量结果，如能量消耗，但只有15.9%的研究验证了生理状态结果，而15.8%的研究验证了姿势/活动类型结果。我们确定了六种可穿戴设备曾用于验证来自两个不同维度的结果，只有两种可穿戴设备（即ActiGraph GT1M和ActiGraph GT3X +）验证了来自所有三个维度的结果。符合给定质量标准的研究百分比在44.7%至92.1%之间。只有18项研究被归类为“低风险”或“有一些担忧”。
儿童和青少年中关于生理状态和姿势/活动结果的验证研究很少。大多数研究未达到已发表的质量原则。需要在验证框架中嵌入标准化方案。
