Assets, stressors, and symptoms of persistent depression over the first year of the COVID-19 pandemic

The coronavirus disease 2019 (COVID-19) pandemic has been accompanied by an increase in depression in U.S. adults. Previous literature suggests that having assets may protect against depression. Using a nationally representative longitudinal panel survey of U.S. adults studied in March and April 2020 and in March and April 2021, we found that (i) 20.3% of U.S. adults reported symptoms of persistent depression in Spring 2020 and Spring 2021, (ii) having more assets was associated with lower symptoms of persistent depression, with financial assets-household income and savings-most strongly associated, and (iii) while having assets appeared to protect persons-in particular those without stressors-from symptoms of persistent depression over the COVID-19 pandemic, having assets did not appear to reduce the effects of job loss, financial difficulties, or relationship stress on symptoms of persistent depression. Efforts to reduce population depression should consider the role played by assets in shaping risk of symptoms of persistent depression.

Persistent depressive symptoms during COVID-19: a national, population-representative, longitudinal study of U.S. adults

BACKGROUND

The COVID-19 pandemic and its consequences have been associated with an increase in poor population mental health. We assessed how depressive symptoms changed among U.S. adults over the course of the COVID-19 pandemic and identified the key risk factors for these symptoms.

METHODS

Longitudinal panel study of a nationally representative group of U.S. adults ages 18 years and older surveyed in March-April 2020 (Time 1; N=1441) and March-April 2021 (Time 2; N=1161) in the COVID-19 and Life Stressors Impact on Mental Health and Well-being study (CLIMB). The Patient Health Questionnaire-9 (PHQ-9) was used to define elevated depressive symptoms (cut-off ≥10) and depressive symptoms score (0-27).

FINDINGS

The prevalence of elevated depressive symptoms persisted from 27.8% in 2020 (95% CI: 24.9, 30.9) to 32.8% in 2021 (95% CI: 29.1, 36.8). Over time, the central drivers of depressive symptoms were low household income, not being married, and experiencing multiple stressors during the COVID-19 pandemic. The odds ratio of elevated depressive symptoms for low income relative to high income persons increased from 2.3 (95% CI: 1.2, 4.2) in 2020 to 7.0 (95% CI: 3.7, 13.3) in 2021. Fewer people reported experiencing 4 or more COVID-19 stressors in 2021 than in 2020 (47.5% in 2020 vs 37.1% in 2021), but the odds ratio of elevated depressive symptoms associated with 4 or more stressors relative to 1 stressor or less increased from 1.9 (95% CI: 1.2, 3.1) in 2020 to 5.4 (95% CI: 3.2, 9.2) in 2021.

INTERPRETATION

The burden of depressive symptoms in the U.S. adult population increased over the course of the COVID-19 pandemic. Mental health gaps grew between populations with different assets and stressor experiences during the COVID-19 pandemic.
