Limited data exist on COVID-19's mental health impact on non-health care workers. Authors estimated the prevalence of depressed mood and suicidal ideation experienced in the past year among California workers and assessed whether the prevalence changed during the COVID-19 pandemic. Researchers analyzed 2013–2020 California Health Interview Survey (CHIS) data using survey-weighted methods to assess the change in the prevalence of depressed mood and suicidal ideation from 2019 to 2020 for working adults by demographics and occupational groups. They identified priority occupation groups with a higher-than-average outcome prevalence in 2020 and rate increases after adjusting for pre-pandemic trends. Analysis included 168,768 respondents, of which 65% were workers.

Findings: Production and service workers were the priority occupation groups for depressed mood and suicidal ideation. Workers aged 45–65 years experienced over a 30% relative increase in both outcomes from 2019 to 2020. Depressed mood and suicidal ideation in the past year increased for production, service, and older workers during the pandemic. These groups should be considered for mental health interventions.
