Mental health issues may lead to higher risk for COVID-19 breakthrough cases, study finds

Individuals vaccinated against COVID-19 who were diagnosed with certain psychiatric disorders were more at risk for getting COVID-19, according to a new study published in JAMA Network Open. 

Overall, the researchers found participants with psychiatric disorders had a 3% increased risk for breakthrough COVID-19 infections in 2021 compared to those without a psychiatric history, according to the release.

The investigators report that the risk was higher for those over 65 years old. According to the release, those in the 65+ age group who had substance abuse issues had a 24% higher risk for a breakthrough case and those with psychotic disorders had a 23% higher risk. The report found those with bipolar disorder were 16% more likely to get a breakthrough infection, while those with an adjustment disorder had a 14 % risk. The individuals with anxiety conditions had a 12% higher chance compared to those who did not have a psychiatric condition, the report said.
