Outline of Final Research Achievements

Effects of air pollution exposure during pregnancy on health of pregnant women and birth outcomes were evaluated on the basis of a birth cohort study. The concentrations of air pollutants inside and outside of the house of pregnant women were measured. The concentrations of fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ozone (O3) outside of the house were correlated with the concentrations at a monitoring station in the city. The concentration of inside PM2.5 was also correlated with that. The levels of serum high-sensitivity C-reactive protein (hs-CRP) and TARC during early pregnancy were affected by smoking habit and BMI. PM2.5 and O3 exposure prior to blood sampling were associated with increased TARC levels, but not hs-CRP. This study show no association between air pollution exposure and low birth weight.
