Pregnancy mindfulness trial explores stress and blood pressure changes
Pregnant participants receiving phone-based mindfulness training had greater blood pressure decreases than those receiving usual care. Lower stress may help explain the upper reading’s change; its size remains unclear.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
In this small randomized trial, phone-based mindfulness training was followed by larger decreases in blood pressure than usual care. The analysis suggested that lower perceived stress could help explain the decrease in systolic pressure, the upper blood pressure reading. It did not establish stress reduction as the cause, and the abstract gives no size for the blood pressure changes.
The abstract does not report the amount of blood pressure change or confidence intervals. This small pilot trial therefore leaves the effect’s size and precision difficult to assess.
What researchers found
Blood pressure change
Upper and lower readings were compared before and after the 8-week program. Both differences were statistically significant; the abstract does not report their size.
What researchers measured
Researchers randomly assigned pregnant participants to phone-delivered mindfulness training or usual care. They compared medical-record blood pressure readings before and after the program and collected questionnaires about depression, anxiety, perceived stress and mindfulness.
What stress might explain
Reduced perceived stress helped statistically explain the systolic change, but did not explain the change in diastolic pressure, the lower blood pressure reading. This analysis suggests a possible pathway rather than confirming how mindfulness affected blood pressure.
