birth weight affected by mother’s exposure to air pollution, new b.c. study says - portable hepa air filter

VANCOUVER—
A researcher at Simon Fraser University said a new study showing fetal growth could be improved by using portable air purifiers at home, reinforcing the urgent need for countries to reduce air pollutants
Ryan Allen, associate professor at the SFU School of Health Sciences and one of the study's leading researchers, said that while the new study focuses on how household air purifiers affect the health of pregnant women and the growth of babies, the conclusion of this study suggests that air pollution needs to be addressed from the source rather than at home.
"The air purifier is only a band at best --
Alan said in an interview.
"What we need to do is reduce pollution from the source.
First of all, we need to work hard to reduce air pollution.
Because once air pollution is discharged, the option to mitigate the risk becomes very limited.
The study, published on Monday at Environment International, showed that in the second and third months of pregnancy, women with air purifiers installed in their homes are born with an average of 85 grams more babies than women without air purifiers use household air purifiers.

Advocating that pregnant women say that the solution to help get closer to reality rather than to prevent fetal alcohol spectrum disorders, nursing mothers warn that in order to avoid Marijana Allen, the team is not yet fully sure why poor air quality affects the size of the baby in labor.
But he said that 20 years of research has shown that air pollution affects the features of blood and vascular function, and that there is an idea that when pregnant women are exposed to air pollution, it may affect the development and function of the placenta. “(This)
"This will affect the delivery of oxygen and nutrients to the fetus," Allen said, adding that these assumptions coincide with how known air pollution affects other systems in the body.
The study was conducted in Ulanbaatar, Mongolia.
It is considered one of the world's most polluted cities in winter because it relies on coal burning to meet energy needs.
The concentration of fine particulate matter in the air in Ulanbaatar is more than seven times the World Health Organization-defined safety annual average.
A group of women received high-efficiency particulate air (HEPA)
From early pregnancy to childbirth, use filter cleaners at home.
The second group (
Or "control" group)was given none.
According to the data cited in the study, the HEPA filter has been shown to reduce the fine particulate matter in the home by about.

The government also recommends that pregnant women stay indoors as much as possible when the air quality advice comes into effect. The SFU-
Led research also pointed out two other research papers
During pregnancy may be a "critical exposure window" for fetal growth ".
The first study suggests that "the effect of air pollution on fetal growth may be the most harmful in the later stages of pregnancy.
The second report said, "Beijing women born in the eighth month of pregnancy during the 2008 Olympic Games have significantly reduced outdoor pollution levels (

In the year before or after the Olympics, the eighth month of the baby dropped.
Allen said that the study team will follow up on the growth of children born in the study to determine whether the development of female-born children who obtained the HEPA filter is different from that of those children in the control group.
He also quickly pointed out that although the 85g difference in baby birth weight is not a huge impact in itself, air pollution is not the only thing women are exposed to during pregnancy.
"Air pollution may slightly affect the growth of the fetus, and some other things may slightly affect the growth of the fetus," he said . ".
"Personally, the impact of these things may be small, but in general they may be substantial.
