The association between newborn cord blood steroids and ambient prenatal exposure to air pollution: findings from the ENVIRONAGE birth cohort

Table 3 Sensitivity analyses for additional variables and for children born via a vaginal birth

Association model	Beta estimate	Standard error	p-value	n
a: 17α-hydroxypregnenolone ~ trimester 3 PM_2.5 exposure	0.009	0.004	0.008	397
a: Androstenedione ~ trimester 1 BC exposure	-0.087	0.030	0.004	378
b: 17α-hydroxypregnenolone ~ trimester 3 PM_2.5 exposure	0.019	0.003	0.001	381
b: Androstenedione ~ trimester 1 BC exposure	-0.093	0.028	0.001	362

The models for the two sensitivity analyses are adjusted for the following covariates: two other trimester-specific main air pollutant exposures, sex of the child, birth weight, smoking during pregnancy, gestational age, age of the mother, the season of delivery, and maternal education; and (a) the models were additionally adjusted for ethnicity, alcohol use, parity, maternal BMI, date of delivery, and gestational weight gain, (b) the models were restricted to children born via a vaginal birth
