Air pollutants linked to abnormal fetal growth

A first study of its kind to be conducted in areas with very high air pollution levels.


According to a new study by Yale University, Chinese moms who were presented with an abnormal state of certain air pollutants amid pregnancy had a higher danger of unusual fetal development. The study is the first of its kind to be conducted in areas with very high air pollution levels.

Scientists collected data from more than 8,000 women in Lanzhou, China, from 2010 to 2012. They also collected the daily average concentration for PM10 — a diverse class of air pollution with health implications — from the government monitoring stations in Lanzhou. Using the ultrasound measures of four fetal growth parameters, they observed the associations between PM10 exposure and risk of abnormal fetal growth.

Yawei Zhang, M.D., associate professor at YSPH, said, “There is a lack of studies investigating the association between air pollution and fetal overgrowth. We analyzed data from the Lanzhou Birth Cohort Study to investigate the hypothesis that exposure to high levels of PM10 during pregnancy increases the risk of abnormal fetal growth, including both undergrowth and overgrowth, to determine if and how expectant mothers could protect themselves from possible contributing pollutants.”

The analysts reliably recognized the positive relationship between larger amounts of presentation to a blend of contaminations from auto vapor, industry discharges, or development exercises and fetal head perimeter abundance.

Pregnant ladies’ home and business locales were gathered through face-to-face meetings, and scientists ascertained day-by-day PM10 fixations by joining every member’s home and street numbers.

Zhang said, “The novel finding that high levels of PM10 are associated with risk of overgrowth should be confirmed by other studies in different populations and that it is also important to identify the specific pollutants that are responsible for this association by investigating the components of PM10.”

“Our results have important public health implications and call for future studies to explore the underlying mechanisms and postnatal consequences of the findings. We are going to replicate the findings in another birth cohort and will continue to identify individuals who are more susceptible to air pollution.”

Ladies in the locale may bring down the danger of fetal excess by picking their initiation time and decreasing their open-air exercises amid the days with high air contamination, said Zhang.

Pregnant ladies who went to the Gansu Provincial Maternity and Child Care Hospital for conveyance in 2010-2012 and who were 18 years or more seasoned with a development period of over 20 weeks were qualified to take an interest in this investigation.
