Inflicted violence-related injuries among children and youth in ontario during the COVID-19 pandemic

Abstract

Background

During the COVID-19 pandemic, it was hypothesized that stay-at-home policies would impact cases of violence, abuse, and neglect among children and youth due to increased familial stressors.

Objective

We examined the effect of the implementation of pandemic policies on violence-related emergency department (ED) visits and hospitalizations among youth.

Participants

Violence-related ED visits and hospitalizations among children and youth ages 0–19 in Ontario, Canada were obtained from April 2015 until the most recent available date, March 31, 2022.

Methods

We used an interrupted time series design to model the change in monthly violence-related ED visits and hospitalizations before and during the pandemic. We used negative binomial models to estimate the immediate effect of the policy and the change in the number of injuries during the pandemic.

Results

After adjusting for seasonality and population changes over our study period, we observed a 56% decrease in violence-related ED visits (RR: 0.44, 95%CI: 0.38, 0.50) and a 35% decrease in hospitalizations (RR: 0.65, 95%CI: 0.52, 0.82) immediately after the implementation of the pandemic policy, followed by moderate increasing trends. We observed no difference in the effect of the pandemic policies on the rate of violence-related ED visits and hospitalizations by sex, age or material deprivation; however, males aged 10–19 years and those in higher quintiles of material deprivation had higher average rates of injuries compared to females, those in younger age groups and lower quintiles of deprivation over the study period.

Conclusions

We observed an abrupt decrease in the rate of violence-related ED visits and hospitalizations immediately after the onset of pandemic policies in Ontario. Following this, violence-related injuries increased, approaching pre-pandemic levels.
