The impact of the COVID-19 pandemic on symptoms of depression and anxiety among older adults: the MYHAT study.

OBJECTIVES

To identify subgroups of older adults whose mental health was affected by the COVID-19 pandemic.

METHODS

Interrupted time series (ITS) analyses were used to measure the long-term impact of the COVID-19 pandemic on symptoms of depression (mCES-D) and anxiety (GAD-7) among participants aged 65 years and older (n = 708) from a prospective, longitudinal cohort study.

RESULTS

Symptoms of depression, but not anxiety, significantly increased at the start of the pandemic, while long-term trends in depression and anxiety during the pandemic were similar to pre-pandemic trends. Participants aged 75 years and older exhibited a more rapid decline in depression symptoms over time than expected after an initial increase. Women experienced a greater immediate increase in anxiety that decreased over time, while men's anxiety increased over time. Cognitively normal participants experienced a greater than expected immediate increase in symptoms of depression that decreased over time, while symptoms were unchanged by the pandemic for those with cognitive impairment.

CONCLUSION

Despite an initial increase in depression symptoms, the pandemic did not result in elevated symptoms of depression and anxiety long-term. The impact of the pandemic on mental health varied by age, gender, and cognitive status, suggesting some groups may have been more vulnerable than others.
