Prenatal ultrafine particle exposure linked to asthma development in children, Study reports
Ambient ultrafine particles (UFPs; <0.1 µm) may exert greater toxicity, compared to other pollution components, due to enhanced oxidative capacity and ability to translocate systemically. Studies examining associations between prenatal UFP exposure and childhood asthma remain sparse.
A recent research published in the has highlighted that prenatal ultrafine particles (UFP) exposure is associated with asthma development in children, independent of correlated ambient NO2 and temperature.
Rosalind J. Wright and colleagues from the Icahn School of Medicine, Environmental Medicine & Public Health, New York, United States daily used ultrafine particle exposure estimates to identify susceptible windows of prenatal ultrafine particle exposure with asthma in children, accounting for sex-specific effects.
Analyses included a total of 376 mother-child dyads followed since pregnancy. Daily ultrafine particle exposure during pregnancy was estimated using a spatiotemporally-resolved particle number concentration prediction model.
