SALT LAKE CITY – Researchers say a new study by the University of Utah Health examining how air quality overlaps with miscarriages has led to "angry" outcomes indicating that women are at greater risk to lose her pregnancy within a few days after a spike in nitrogen dioxide pollution along the US Wasatch Front.
U. The researchers used data from more than 1,300 women from Utah who visited the emergency department of the University of Utah Hospital due to miscarriage between 2007 and 2015. They also studied seven days of measurements showing elevated levels of three common air pollutants: nitrogen dioxide, ozone and small particles.
An analysis of the University of Utah data by the researchers revealed that "women were exposed during the seven-day window after an increase in nitrogen oxide levels in the air along the Wasatch front." "The result of this study is amazing and we need to work together as a society to find constructive solutions," said Dr. Matthew Fuller In a prepared statement, the senior author and assistant professor of surgery at the University of Utah Health at the University of Utah Health.
The study was published this month in the peer-reviewed journal Fertility and Sterility, a publication of the American Society for Reproductive Medicine. Summing up its findings, the researchers found that peaks in particulate matter concentrations "were associated with an increased risk of spontaneous pregnancy loss," but unlike nitric oxide, such a correlation "did not reach statistical significance."
The study adds its conclusion that "we have found no evidence of increased risk" associated with ozone levels.
Fuller and his colleagues endeavored to control other potentially disruptive variables, including the age of the mother, as U. Health Science writer Stacy Kish in a publication. Miscarriages in gestational stages up to 20 weeks were counted.
"Fuller recommends women talk to their doctor about health issues," Kish wrote. "Women can manage the risk by using an N95 respirator with particulate matter to filter out pollutants or avoid physical activity on bad-air days Women can also use filters to reduce indoor air pollution and, if possible, limiting the time to avoid seasonal episodes of poor air quality. "
Kish stated that the Wasatch front spits short periods of poor air quality," especially in the winter months, when inversions trap pollutants near the bottom. "
Previous studies have also linked poor health issues such as premature birth, asthma and increased risk of heart attack. Fuller said that the new findings on the loss of pregnancy have an impact on the families of Utah, as well as on those who are concerned about the effects of air quality on their health.
"Although we live in a rather unique geographical area, but with the problems we face, air pollution is not unique," he said. "With the planet warming and the population booming, air pollution is becoming a major problem not only in developing countries, but throughout the United States."
U. Research analyst Claire Leiser, first lead author of the study, warned of limitations in the study because her data were sourced exclusively from women who received care after a miscarriage in a single emergency room, and not from women in Utah who received help elsewhere, for example, by a family doctor or obstetrician.
"We really only see the worst cases in a small time window," Leiser said in a statement. "These results are not the whole picture."
The study was also limited in that it could "find no critical phase in early pregnancy," "when the fetus is most susceptible to contaminants," says Kish. 1
