Injury by knife crime amongst children is associated with socioeconomic deprivation: an observational study

Abstract

Abstract Purpose Children who live in areas of socioeconomic deprivation may be at higher risk of being victims of violent crime such as knife wounds. The current study investigated whether socioeconomic disparity was associated with higher risk of knife crime. Methods An observational study included patients aged ≤ 17 years at a UK Major Trauma Centre injured by knife trauma from 2016 to 2022. Indices of deprivation were recorded according to the zip code of residence and compared with those of all of England. These included Index of Multiple Deprivation (IMD); income; employment; education and skills; health and disability; crime; barriers to housing and services; living environment; and Income Deprivation Affecting Children Index (IDACI). Results There were 139 patients (96% male) with median age of 16 years. When compared with the whole of England, patients had worse indices of IMD (p = 0.021); income (p < 0.001); employment (p < 0.001); education and skills (p < 0.001); health and disability; and IDACI (p < 0.001). There were no significant differences in indices of crime, barriers to housing and services or living environment. Conclusions Paediatric knife injury was associated with poor socioeconomic status in multiple domains. Focussed efforts to address socioeconomic disparities should be a priority as a public health measure for vulnerable children.
