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. Objectives: This systematic review aims to determine the relationship between PA and SA in children to inform alternative preventative and interventional strategies. Methods: 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\u201318 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. Results: 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. Conclusions: 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.<\/jats:p>","DOI":"10.3390\/children12070890","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T11:19:27Z","timestamp":1751887167000},"page":"890","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Impact of Physical Activity on Suicide Attempt in Children: A Systematic Review"],"prefix":"10.3390","volume":"12","author":[{"given":"Marissa","family":"Patel","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Bond University, Robina, QLD 4226, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6578-2718","authenticated-orcid":false,"given":"Grace","family":"Branjerdporn","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Bond University, Robina, QLD 4226, Australia"},{"name":"Mental Health and Specialist Services, Gold Coast Health, Gold Coast, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4753-4344","authenticated-orcid":false,"given":"Sabine","family":"Woerwag-Mehta","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Bond University, Robina, QLD 4226, Australia"},{"name":"Mental Health and Specialist Services, Gold Coast Health, Gold Coast, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,6]]},"reference":[{"key":"ref_1","unstructured":"World Health Organisation (2021).
