An analysis of fertility records in New Jersey (USA) has shown that pregnant women go through a long and stressful way every morning to work is harming the baby in their abdomen.
According to researchers at Lehigh Pennsylvania University, pregnant women frequently experience “chronic stress” from a distance of more than 80km, more likely to give birth to low-birth-weight babies.
In the study published in the Journal of Economics & Human Biology, the researchers found that the pregnant women after 80km of the first move, every 16km extended will increase the likelihood of having a low-birth-weight baby. up 14% more than the average pregnant pregnant women, while slowing the development of the fetus in their abdomen by 43%.
Children born under 2.5kg are considered low birth weight.
Pregnant women often have to travel over long distances to have less time to go for antenatal care than women who live closer to the office.
Speaking in Medical News, Professor Muzhe Yang of Lehigh Pennsylvania University and co-author of the study said: “The discovery of low birth weight of children may be related to the source of stress. straight as long-distance travel seems to have been surmised, because people have found that chronic stress is related to adverse birth outcomes. ”
“However, it is also surprising that the study found that quite a number of pregnant women frequently travel over long distances.”
About 2.2 million US workers travel at least 80km each way from home to work. About 1.7 million workers spend 90 minutes or more to go and return.
According to census data, the time spent traveling in New Jersey is the longest in the United States, at 31.0 minutes, compared with 25.9 minutes in the rest of the federation.
Through studying the birth records of the New Jersey Department of Health, the researchers also found that women who regularly travel between 80 and 160km tend to not go for pregnancy tests in the first three months, even throughout. whole pregnancy until birth.
Yang said the study is the first study of the effects of long-term travel on pregnancy, showing the importance of flexibility in setting hours for pregnant women.
“The necessary respite during pre-natal period is especially important for pregnant women who often have to work long distances.”
