Suicide in children is a major global health crisis, with profound impacts on families, friends, and society. Understanding ways to ameliorate the rate of suicide attempt (SA) is critical given that it is a key factor in predicting future suicide risk. SA is the deliberate act of causing physical injury to oneself with the intent of death. The incidence of SA may be influenced by physical activity (PA). PA includes bodily movement via skeletal muscles that results in energy expenditure and physical fitness. While there is evidence to suggest that PA improves dysregulation of the parasympathetic nervous system which underpins the physiology of suicidal behaviour, evaluating the impact of PA on SA in children is required. : This systematic review aims to determine the relationship between PA and SA in children to inform alternative preventative and interventional strategies. : This systematic review was registered with PROSPERO: CRD42023389415. Eight electronic databases were systematically searched. References were transferred to Covidence software for title and abstract screening and full text review were performed based on eligibility criteria: (1) children aged 6-18 years old; (2) participated in PA (individual, group exercise, or team sports); and (3) examined SA as a dependent variable. The JBI Checklist was used to measure the quality and level of bias of included studies. : Of the 2322 studies identified, 21 were included in the final analysis of the review. Twenty studies were cross-sectional in design, and one implemented a prospective study design. Thirteen studies (61.9%) yielded statistically significant results, indicating that increased PA, particularly team sport, may be associated with reduced odds of SA. There was some evidence to suggest that certain intensities and frequencies of PA may be beneficial to some and detrimental to other subgroups. : The results suggest that PA may reduce the risk of suicide attempts. Although PA may be associated with reduced SA in children, future research is required, which (1) uses standardised outcome variables; (2) adopts longitudinal and experimental study designs; (3) explores qualitative research to determine distinctive factors that influence participation in PA not captured by quantitative research; and (4) examines different target populations such as children with a broad range of mental health issues.
儿童自杀是一场重大的全球健康危机，对家庭、朋友和社会都有深远影响。鉴于自杀未遂率（SA）是预测未来自杀风险的关键因素，了解改善自杀未遂率的方法至关重要。自杀未遂是指故意对自己造成身体伤害并意图死亡的行为。自杀未遂的发生率可能受身体活动（PA）的影响。身体活动包括通过骨骼肌进行的身体运动，这种运动导致能量消耗和身体健康。虽然有证据表明身体活动可改善副交感神经系统的失调，而这种失调是自杀行为生理学的基础，但仍需要评估身体活动对儿童自杀未遂的影响。：本系统评价旨在确定儿童身体活动与自杀未遂之间的关系，为替代性预防和干预策略提供依据。：本系统评价已在国际前瞻性注册系统（PROSPERO）注册：CRD42023389415。对八个电子数据库进行了系统检索。参考文献被转移到Covidence软件进行标题和摘要筛选，并根据纳入标准进行全文审查：（1）6至18岁的儿童；（2）参与身体活动（个人、团体运动或团队运动）；（3）将自杀未遂作为因变量进行研究。使用澳大利亚乔安娜布里格斯循证护理中心（JBI）核对清单来衡量纳入研究的质量和偏倚程度。：在识别出的2322项研究中，有21项被纳入本评价的最终分析。20项研究为横断面设计，1项采用前瞻性研究设计。13项研究（61.9%）得出了具有统计学意义的结果，表明身体活动增加，特别是团队运动，可能与自杀未遂几率降低有关。有一些证据表明，特定强度和频率的身体活动可能对某些亚组有益，而对其他亚组有害。：结果表明，身体活动可能会降低自杀未遂的风险。虽然身体活动可能与儿童自杀未遂率降低有关，但未来仍需要开展研究，（1）使用标准化的结果变量；（2）采用纵向和实验性研究设计；（3）探索定性研究，以确定定量研究未涵盖的影响参与身体活动的独特因素；（4）研究不同的目标人群，如患有广泛心理健康问题的儿童。
