Pregnant women who are in tune with how toxins can harm their unborn babies are right to be concerned about air pollution. The issue of the possible many deleterious effects of pollution on health is taken seriously in Syracuse where the New York Department of Environmental Conservation offers a free daily online air pollution index from AirNow.
ScienceDaily has reported “Prenatal Exposure to Environmental Pollutants May Affect Weight and Size of Newborn”. It has been discovered by University of Granada researchers that infants born to women living in large cities are more likely to have higher weight at birth than those born to mothers living in rural areas. The researchers have said this is probably due to a higher exposure to xenoestrogens, whuich is a type of environmental pollutants that act like hormones. This research establishes a correlation between estrogenic burden in pregnant women’s placenta and a higher birth weight of their babies.
In this study the researchers examined two groups of pregnant women. The first group was composed of pregnant women who lived in Madrid, while the second consisted of women who lived in Granada. The researchers discovered that there were biological, demographic and socioeconomic differences between both groups of women, which determined the presence of xenoestrogens in the placenta due to exposure to environmental chemicals.
The first group of mothers was made up of women living in Madrid, having a medium-high educational level, many of whom had jobs. By contrast, the mothers sampled in the second group lived in rural areas of the province of Granada with a low educational level, many of whom took care of their homes. All of these factors determine environmental exposure
A correlation was found between anthropometric and sociodemographic factors, health status, lifestyle and working conditions, and the total estrogenic burden. The researchers discovered that the estrogenic effect of placental tissue extract is directly related with certain characteristics in parents, childbirth and newborn babies.
The group with higher estrogenic effect of placental tissue extract in the alpha fraction was that of older women with lower body mass index who lived in Madrid. Furthermore, this is the group which gave birth to higher weight infants. These results have suggested that estrogenicity of xenostrogens directly affects embryo-fetal development. So pregnant women would be wise to make every effort possible to avoid pollution.
