Scientists used fitness tracker WHOOP to monitor heart rate during pregnancy

Wearing a wrist-strap heart rate tracker during pregnancy may help doctors predict who is at risk for premature birth.
In previous research, shon rowan Researchers at West Virginia University recruited 18 women to wear heart-tracking wrist straps from the brand WHOOP throughout their pregnancies.
They were all born at term, and tracking data showed that heart rate variability (the variation in the time interval between heartbeats) decreased clearly during the first 33 weeks of pregnancy, and then steadily increased until birth. It became clear.
Rowan was curious to see if the same pattern occurred in people who give birth prematurely. Emily Capodilupo A larger study is being conducted at WHOOP in Boston, Massachusetts. They and colleagues analyzed tracker data provided by 241 pregnant women between the ages of 23 and 47 in the United States and 15 other countries. It is unclear whether this data includes data for transgender men.
All participants were pregnant with one child born between March 2021 and October 2022. In total, more than 24,000 heart rate variability records were provided.
Similar to the previous study, those who gave birth at term showed an obvious switch in heart rate variability around 33 weeks of gestation, or an average of seven weeks before delivery.
However, the 8.7% who were born prematurely had much less consistent patterns of heart rate variability, Rowan said. This change from decrease to increase in variability occurred at different times during pregnancy, but similar to those born at term, the change occurred on average about 7 weeks before birth, although the birth was premature. It seemed like there was.
In the future, the device could identify pregnancies that require closer monitoring or benefit from administering drugs such as steroids to help the fetus' lungs develop, Rowan said.
You can also plan to stay near hospitals that provide specialized care, which can be especially helpful for people who live in remote areas, he says.
“Once we are able to remotely monitor some of their health using things like the WHOOP tracker, and we start to see changes in that. [in heart rate variability]Then you might be able to be a little more proactive,” says Rowan.
