A new study conducted by Buffalo University revealed a link between the influence of polluted air at late pregnancy and the increased risk of newborn hospitalization in the intensive care department.
Researchers have studied the data on air pollution obtained from satellites and the amount of revenues in the intensive care unit of newborns. Particular attention was paid to common contaminants such as nitrogen dioxide (NO2), small particles inhaling, (PM2.5) and ozone (O3).
The conclusions of the study showed that in newborns who have been exposed to higher no2 concentrations in the last month of pregnancy, the risk of hospitalization in the intensive care unit increases by 30-35%, and the risk associated with PM2.5 increases by 11-22%.
“Our results emphasize the critical effect of air pollution in the last weeks of pregnancy, during the period of increased vulnerability of the fetus,” says the author of the study Johan VA Firi.
According to Firi, the effect of polluted air during pregnancy is associated with a number of adverse effects on newborns, including congenital defects, premature births and fetal growth disorders.
The study also found that the risk of hospitalization in the intensive care unit of newborns varies depending on the US region. For example, there was a lower risk in the large plains, which may be due to restricted access to such departments in rural areas.
“We saw the highest risks to NO2 and average risks to PM2.5,” Fir said, adding that the results of ozone either showed a protective effect or lack of differences between groups, except for summer.
Geographically, the regions of the Middle West and the Middle Atlantic had the highest chances of receiving newborns in the intensive care unit due to NO2. For PM2.5, seasonal fluctuations with constant risks along the west coast and in the southeast were noted. In the summer, the risks were widespread, while in winter the risks were the highest in the northeast, Firi said.
Researchers hope that their work will draw attention to the problem of air pollution and will help to improve the quality of air, especially for pregnant women.
