May 31, 2024 – New research shows that pregnant women usually tend to have premature and early births after 4 days of warmth waves.
The researchers examined the health data of 53 million women who gave birth in 50 metropolitan areas within the United States between 1993 and 2017. They found that there have been 2% more preterm births and 1% more premature births after a four-day heat wave. The results were published within the journal JAMA network opened.
According to the study, each one degree Celsius increase in average temperature above the brink was related to a one percent increase in the speed of preterm and premature births.
The finding comes at the best time, as a extremely popular summer is anticipated after the summer of 2023 with record temperatures this yr, the researchers said.
“We are predicting a very warm summer this year, and due to climate change, we will see more heat waves in the future,” said Dr. Howard Chang, professor of biostatistics and bioinformatics on the Rollins School of Public Health at Emory University and lead creator of the study, in a press release. “Our study shows that this increase in temperature could lead to worse outcomes for babies, as premature babies may have health problems and additional health care costs.”
According to the study, a heat wave occurred when the typical temperature on 4 consecutive days was higher than on 97.5% of the standard days. Premature births occur before the thirty seventh week of pregnancy, and premature births before the thirty ninth week of pregnancy. The normal length of pregnancy is 40 weeks.
According to the study, heatwaves have exposed health care inequities, with moms who were 29 years old or younger, had a highschool education or less, and were from an ethnic or racial minority group being much more more likely to have a preterm or premature birth following a heatwave.
The researchers said this might be resulting from a scarcity of air-con and poor access to health care.
