 The study examined the impact of the COVID-19 pandemic on depression rates in the United States from 2011 to 2021. The authors found that depression rates were already rising prior to the pandemic, and there was no significant change in depression rates at the start of the pandemic compared to previous trends. However, they did observe a 3% increase in depression rates in 2021. Additionally, the study found that certain demographic groups experienced more pronounced increases in depression rates than others.
