According to a US government-commissioned study of the US Center for Disease Control and Prevention (CDC), the risk of stillbirth is about twice as high in women with COVID-19 compared to women without the coronavirus, and it has almost quadrupled over the period when Delta variant became dominant.
The risk of stillbirth is about twice as high in women with Covid-19 compared to women without the coronavirus, and it has almost quadrupled as the Delta variant became dominant, according to a US government-commissioned study published on Friday.
The analysis, conducted by the U.S. Centers for Disease Control and Prevention (CDC), was based on over 1.2 million data collected between March 2020 and September 2021 from the largest hospitals in the country.
Study: COVID-19 significantly increases the risk of miscarriage
In general, stillbirths were very rare and accounted for 0.65% of the total stillbirth. or 8,154 births. However, after using statistical methods to account for other variables that could influence the outcome, it was found that stillbirths were 1.47 times more common among Covid-19 positive mothers before Delta, 4.04 times more often after and 1 , 9 times more often in total.
Among the births of women with COVID-19, conditions such as chronic hypertension, having more than one child, heart disease, separation of the placenta from the uterus, sepsis, poor blood flow causing shock, life-threatening lung damage, and the need for a ventilator or ICU have been associated with a higher stillbirth rate.
“Additional studies are warranted to investigate the impact of complications from COVID-19 on the risk of stillbirth,” and are considered the most significant in linking COVID-19 to stillbirth, the authors of the study believe. The current analysis covers an additional year of data, bringing more and more evidence that COVID-19 is associated with an increased risk of stillbirth, ‘they wrote.
