Stress, anxiety boost chances of getting long Covid: Study

Depression, anxiety, worries about the pandemic and other sources of distress prior to getting Covid-19 may increase the chance of developing persistent “long-haul” symptoms, a Harvard University study found.

Depression, anxiety, worries about the pandemic and other sources of distress prior to getting Covid-19 may increase the chance of developing persistent “long-haul” symptoms, a Harvard University study found. Preinfection psychological distress was associated with a higher risk of post-Covid conditions, researchers at the Harvard T.H. Chan School of Medicine in Boston said. Their study, which tracked some 55,000 people over 19 months, found the link increased in a dose-dependent manner. Those who experienced two or more types of distress before their infection had almost a 50% greater risk of self-reported impairment lasting four weeks or more.

Lingering symptoms -- spanning chronic fatigue and “brain fog” to hair loss and shortness of breath -- are estimated to afflict some 10% to 20% of Covid survivors. No one knows yet what causes them, though obesity, female sex, hypertension and a weakened immune system are among purported risk factors. With long Covid estimated to cost $3.7 trillion in the US alone, there’s an urgent need to understand the condition to find ways to treat and prevent it.

What Experts Know About ‘Long Covid’ and Who Gets It

Psychological distress has been linked to longer and more severe illness after respiratory tract infections, and it might drive the kind of immune activation and dysregulation implicated in long Covid, the Harvard researchers said in the study published Wednesday in the journal JAMA Psychiatry.

Long Covid differs substantially from symptoms of mental illness, and the results shouldn’t be misinterpreted as supporting a hypothesis that the condition is psychosomatic, or has no medical explanation, the researchers said. Among respondents who developed post-Covid conditions, more than 40% had no reported distress prior to catching the coronavirus.

The study, which examined some common, yet largely unstudied types of distress, including loneliness, used data from other cohort studies in which participants were often white female health-care workers. That might limit how generalizable the study’s findings are to other groups, the authors said.
