On May 19, 2022, the U.S. National Institutes of Health (NIH) announced that people who reported in a survey that they felt worried, depressed or lonely had a greater chance of being hospitalized after a COVID-19 diagnosis.

The study, which analyzed survey data from more than 54,000 female nurses and their offspring, was conducted by Andrea L. Roberts, Ph.D., of the Harvard T.H. Chan School of Public Health, Boston, and colleagues. It was published in Psychological Medicine.
