A study in the American American Heart Association Journal on Wednesday showed that more babies are likely to be born with congenital heart defects between 2025 and 2035, due to their mother's exposure to higher temperatures caused by climate change, while pregnant. This is especially true for mothers who were pregnant through spring or summer. Climate change may result in another 7,000 additional cases of congenital heart defects in the United States for a period of 11 years, according to the study. The Midwest is likely to see the largest percentage increase, followed by the southern and northeastern United States.
Earlier researches were found that climate change could "stop and regain" the progress made in human health over the past century, but there are more limited research on the influence it has of pregnancy, the authors said. Congenital heart defects are the most common type of birth defects and can harm the overall health of the baby and potentially impact how their body works or develops.
"The potential increase in the number of pregnant women and the exposure to heat in the mother indicate an alarming effect that climate change can have on reproductive health," the study said.
The researchers realized this, looking at the data collected in the National Prevention of birth defects study, a large population-based population study that examined the risk factors for major structural defects at birth. They also looked at them climate data from the US government.
Based on climate data projections, the entire United States will face higher temperatures. New York, the countries of the Midwest, such as Iowa and southeastern countries, such as Georgia and North Carolina, are likely to notice higher temperature increases. There will be more variations in temperature for southern states, such as Texas and Arkansas, and from the west to states like California in the summer months.
It is not clear what is the relationship between high temperatures and congenital heart problems. Animal studies were found that heat can cause death of fetal cells and can adversely affect proteins that play a key role in the development of the fetus.
This ongoing research is based on the previous work she found when the temperature remains high can harm the mother's chances of wearing a baby for a mandate. Extreme heat also puts mothers at risk of early birth. Cats exposed to high heat have a greater chance of having a small or insufficient weight on the baby. Mothers who suffer high temperatures at the beginning of pregnancy have a much greater risk that their baby will have congenital heart problems, according to previous studies.
"Our findings highlight the alarming impact of climate change on human health and emphasize the need for better preparedness to cope with the expected increase in a complex state that often requires lifelong care and monitoring," said study author Dr. Shao Lin, a professor in The School of Public Health at the University of Albany. "Although this study is preliminary, in the early weeks of pregnancy it would be wise for women to avoid heat extensions similar to those given to people with cardiovascular and pulmonary diseases during heat spells."
