Background : Self-harm and suicide are major public health problems with immediate and long-term effects on individuals, families, and communities. In 2020 and 2021, stressors wrought by the COVID-19 pandemic, stay-at-home mandates, economic turmoil, social unrest, and growing inequality likely modified risk for self-harm. The coinciding surge in firearm purchasing may have increased risk for firearm suicide. In this study, we examined changes in counts and rates of fatal and nonfatal intentional self-harm in California across sociodemographic groups during the first two years of the COVID-19 pandemic relative to prior years.
METHODS: We used California-wide death data and University of California (UC)-wide hospital data to summarize fatal and nonfatal instances of intentional self-harm across race/ethnicity, age, education, gender, region, and method of harm. We compared case counts and rates in 2020 and 2021 with 2017-2019 averages.
RESULTS : Suicide decreased overall in 2020 (4123 deaths; 10.5 per 100,000) and 2021 (4104; 10.4 per 100,000), compared to pre-pandemic (4484; 11.4 per 100,000). The decrease in counts was driven largely by males, white, and middle-aged Californians. Conversely, Black Californians and young people (age 10-19) experienced increased burden and rates of suicide. Firearm suicide also decreased following the onset of the pandemic, but relatively less than overall suicide; as a result, the proportion of suicides that involved a firearm increased (from 36.1% pre-pandemic to 37.6% in 2020 and 38.1% in 2021). Females, people aged 20-29, and Black Californians had the largest increase in the likelihood of using a firearm in suicide following the onset of the pandemic. Counts and rates of nonfatal, intentional self-harm in UC hospitals increased in 2020 (2160; 30.7 per 100,000) and 2021 (2175; 30.9 per 100,000) compared to pre-pandemic (2083; 29.6 per 100,000), especially among young people (age 10-19), females, and Hispanic Californians.
CONCLUSIONS : The COVID-19 pandemic and co-occurring stressors coincided with heterogeneous changes in risk of self-harm and suicide across the California population. Marginalized racial groups, females, and younger people experienced increased risk for self-harm, particularly involving a firearm. Public health intervention and policy action are necessary to prevent fatal and nonfatal self-harm injuries and reduce related inequities.
