A study by the Journal of the American Heart Association on Wednesday found that probably a larger number of babies was born with congenital heart defects between 2025 and 2035 due to the exposure of mothers to higher temperatures, caused for climate change, while pregnant. This is especially true for mothers who were pregnant through spring or summer. Climate change could result in up to 7,000 additional cases of congenital heart defects in the United States over a period of 11 years, according to the study. The Midwest will probably see the highest percentage increase, followed by the southern and northeastern United States.
You have found previous research that climate change could "stop and invest" the advances made in human health during the last century, but there is more limited research on the impact it has In pregnancy, the authors said. Congenital heart defects are the most common type of congenital defects and can hurt the general health of a baby and can affect the body's functioning or development.
"The potential increases in the number of pregnant women and the exposure to maternal heat suggest an alarming effect that climate change may have on reproductive health," said the study.
The researchers discovered this by observing the data collected in the National Study for the Prevention of Birth Defects, a large multicenter study based on the population that investigated risk factors for major structural defects of birth. They also watched Climate data from the US government.
Based on climatic data projections, the whole United States will face higher temperatures. New York, the states of the Midwest, such as Iowa and the Southeast states, such as Georgia and North Carolina, will probably experience higher temperature increases. There will be a greater temperature variation for the southern states, such as Texas and Arkansas and westwards in states like California during the summer months.
It is unclear what is the link between high temperatures and congenital heart problems. They have found animal studies That heat can cause the death of the fetal cell and can negatively affect proteins that play a crucial role in fetal development.
This current search is based on previous work that was found When the temperature remains high, it may damage the likelihood of having a baby out. Extreme heat also puts mothers at risk of giving birth at an hour. Mothers exposed to heat have a greater chance of having a small or low birth weight baby. Mothers who support high temperatures at the beginning of their pregnancy are at a much higher risk than their baby has congenital heart problems, the previous research has found.
"Our findings underline the alarming impact of climate change on human health and emphasize the need for better preparedness to face the expected increase in a complex illness that often requires care and follow-up of life "said the author of the study, Dr. Shao Lin, professor at the School of Public Health of the University of Albany. "Although this study is preliminary, it would be prudent that women in the first weeks of pregnancy avoid extremes of heat similar to the advice given to people with cardiovascular and pulmonary disease during spells."
