Coronavirus significantly increases risk of stillbirth, says US study

Washington:

The risk of stillbirth for women with covid is almost twice that of those without, and nearly quadrupled during the period when the delta version took effect, a large US government study said on Friday.

The analysis by the Centers for Disease Control and Prevention (CDC) was based on more than 1.2 million deliveries between March 2020 and September 2021 from a large US hospital database.

Overall, stillbirths were extremely rare, accounting for 0.65 percent or 8,154 stillbirths.

But, after using statistical methods to take into account the effect of other variables that may have biased the results, stillbirth was 1.47 times more common in pre-delta in covid-positive mothers, followed by 4.04 times more was 1.90 times higher overall.

The authors write that previous research suggested that a possible biological reason for the increased risk could be the result of inflammation in the placenta or decreased blood flow.

Between deliveries with COVID-19, chronic high blood pressure, multiple births, heart injury, placental abruption, sepsis, poor blood flow resulting in shock, life-threatening lung injury, and Being on a ventilator or being admitted to the ICU was associated with higher rates of stillbirths.

“Additional studies are needed to examine the role of maternal complications on the risk of stillbirth from COVID-19,” he said.

The authors said the study is one of the strongest linking covid and stillbirth.

Some previous research on this topic failed to adjust for pre-existing conditions such as “confounders”, and a previous analysis using the same dataset did not reveal a significantly increased risk.

“The current analysis includes an additional year of data, adding to the growing evidence that COVID-19 is associated with an increased risk for stillbirth,” the authors wrote, explaining why the link was now more clear.
