NIH-funded study showed blood pressure levels rose during pandemic

On Nov. 1, 2022, the National Institutes of Health (NIH) announced that adults with hypertension saw a small, but consequential, rise in their blood pressure levels during the first eight months of the COVID-19 pandemic, while the number of times they had their blood pressure measured dropped significantly.

In the study, researchers looked at the electronic data records of 137,593 adults with hypertension and compared blood pressure outcomes before the pandemic (August 2018 through January 2020) with those during the peak of the pandemic (April 2020 through January 2021). The study was funded by the National Heart, Lung, and Blood Institute (NHLBI).

The researchers discovered first that the number of blood pressure measurements patients had taken declined significantly in the first three months of the pandemic — by as much as 90% compared to before the pandemic. While these measurements gradually ticked up as the months passed, the total number of readings at the end of the study period remained below pre-pandemic levels. The researchers believe this was partly because of cancellations or postponements of face-to-face office visits. The findings, which appeared in the journal Hypertension, represent one of the most extensive looks at blood pressure trends during the early months of the pandemic.
