Exposure to built environmental features was defined using participants’ neighbourhood study site. Violence perpetration was measured by three survey items: physical fighting, threatening someone with a weapon, and injuring someone with a weapon. Logistic regression models examined associations between each environmental feature and violence perpetration.Results Better neighbourhood walkability was associated with significantly lower odds of fighting (adjusted odds ratio (AOR)=0.86, 95% CI 0.76 to 0.99). Alcohol and tobacco outlets were associated with slightly lower odds of violence perpetration (AORs=0.89–0.96).Conclusions This work extends previous studies from large urban centres to a mid-sized city context and suggests that walkable neighbourhoods create opportunities for social interactions and may serve as a protective factor in youth violence. %U https://injuryprevention.bmj.com/content/injuryprev/26/6/588.full.pdf
