Abstract Background Since , the number of violent crimes and offences by sharp instruments have increased continually, following a previous decrease, with majority of cases occurring among young people and in London. Results No association was found between gender or ethnicity and youth violence, contrasting current understanding shown within media.

Conclusions Several risk factors were identified, with evidence currently heterogeneous with minimal high-quality studies. Systematic review registration number CRD Background Youth violence, as defined in Fig. Definitions of key terms mentioned within the review. Full size image. Rationale There has been a clear and consistent rise in police-recorded incidents involving a knife or sharp instrument in the UK since [ 5 ], with weapon-crime described as a new epidemic [ 12 ]. Search strategy A research phase enabled the development of search terms Fig.

Results Study selection, data extraction and analysis A two-stage screening process was conducted, identifying articles eligible for study involvement. Table 1 Results of the quality analysis of papers. Table displays results from quality analysis, using WOE approach, of papers meeting the systematic review criteria.

Full size table. Table 2 Summary of risk factors included studies. Displays which risk factors - associated with youth violence - are described in papers and whether there is a positive, no, or unclear association. For papers including a quantitative analysis, risk factors with statistically significant results were categorised as positively associated.

Whereas for qualitative studies, risk factors mentioned within interviews or literature reviews were identified as positively associated. The design of each study is further highlighted within the table. The count of studies mentioning each risk factor was used to determine the relevance for discussion Full size table. Ethnicity and community factors Results did not identify a strong relationship between ethnicity and youth violence when controlling for confounders, such as SES [ 20 , 25 , 31 ], which contrasts information displayed in the media.

Gender This systematic review did not reveal a clear association between gender and youth violence. Adverse childhood experiences Seven studies identified ACEs as significant risk factors for weapon-related crime, which strongly supports the relationship between early childhood trauma and violence.

Strengths and limitations There is limited understanding of risk factors for weapon-related crime among young people and current knowledge of gangs has mostly been derived from research conducted within the USA, which means findings will be influenced by its environment of high gun ownership and incarceration rates.

Comparison with previous literature The identification of risk factors such as ACEs and poor mental health is in line with previous knowledge as a relationship exists between trauma and involvement within weapon-related crime. Policy implications As no clear association was found between gender, ethnicity and weapon-related crime, policy makers should avoid targeting individuals based on stereotypes in these areas. Conclusion Youth violence is an increasing public health issue within the UK and London in particular.
