  1. Levels of PM10 and PM2.5 were in the form of quartile in this multivariable model. Model 1 adjusted parental age, maternal education level, premature, sex, birth weight during each time window. Model 2 adjusted dietary habit, anxiety, depression, life event during each time window based on Model 1. Model 3 adjusted indoor air pollution during each time window based on Model 2
