Anxiety and depressive symptoms increased among U.S. adults during the COVID-19 pandemic

An observational study tracked symptoms of anxiety or depressive disorder and mental health care use among adults in the United States during the COVID-19 pandemic. The study period was from August 2020 to February 2021. No comparator group was specified, and the sample size was not reported.

The main finding was that the percentage of adults reporting recent symptoms of an anxiety or depressive disorder increased from 36% to 42% over the study period. The largest increases in symptoms were observed among two subgroups: adults aged 18-29 years and adults with less than a high school education. Specific effect sizes, absolute numbers, and statistical measures (p-values or confidence intervals) for these increases were not reported.

Safety and tolerability data were not reported. Key limitations include the observational design, which can only show association and not causation. The data are specific to U.S. adults during a defined period of the pandemic, and generalizability to other populations or timeframes is uncertain. The study's funding and conflicts of interest were not reported.

For clinical practice, this evidence highlights a concerning trend in population mental health metrics during the pandemic. However, clinicians should interpret the findings as descriptive associations. The data do not provide causal evidence that the pandemic directly increased symptoms, nor do they offer specific guidance on individual patient management beyond reinforcing awareness of vulnerable subgroups.
