Women living near foremost, heavily-trafficked roads was more expected to give birth prematurely, perhaps because of traffic-related air pollution, according to a Japanese study. But the research study assumed it was still too early to observe a clear link, while other medical experts stated that, there might be another factor also involved in the prematurely birth and it is noise pollution.
In the research study, published in "Epidemiology," Yorifuji and his colleagues studied more than 14,000 newly babies born between 1997 and 2008 in Shizuoka, approximately 150 km (94 miles) west of Tokyo, obtaining comprehensive records on each pregnancy and how close to major roads the mothers lived.
"The study team articulates that, Air pollution is considered to be a potentially significant risk factor of premature births," Yorifuji believed.
Largely, and overall 15 percent of women living within 200 meters of a major road gave birth before 37 weeks, compared to 10 percent of those living further away. A normal pregnancy is 40 weeks. Other factors have been caused of premature birth as well, such as age, job, and smoking. But even after considering and measurement for those, the research team found a 50 percent raise in premature births among women living subsequently to extremely trafficked main road.
There is a high risk of premature birth among these women who delivering before 32 and 28 weeks. Exceptionally preterm births carry an especially heavy community health trouble. "In addition, we found a higher risk in housewives to compare with outside workers, and housewives would almost certainly use up more time at home during their pregnancy, and reproduce further precise revelation," Yorifuji further stated about the issue regarding premature birth. Women living close to busy roads also had a risk of high blood pressure and early break of the membranes surrounding the fetus, both possibly reason of prematurely.
Medical experts said that we have already been mentioned about the previous studies linking air pollution to high blood pressure and inflammation, which may possibly lead to premature rupture of the membranes. "Each person regarding about the premature babies’ birth always fears that it’s not actually living by busy roadways, but that it’s factors which are involved in premature birth," believed Beate Ritz of the University of California, Los Angeles, who reviewed Yorifuji study for publication.
"After all the modification, the effect and cause was still there," she further stated that we couldn’t ignore the factor of noise pollution.
So what are the precautions and useful suggestions about the pregnant woman adopt if she lives near to heavily traffic and close to a national highway?
Yorifuji recommended that pregnant women have a compulsion to living near and close to heavy traffic and thoroughfares then I recommended avoiding smoking and improving her diet. Other experts stated, that studies have revealed that it is common for women to move during pregnancy, and that if possible pregnant women should avoid moving away from busy roads and highways.
