Gestational exposure to organochlorine compounds and metals and infant birth weight: effect modification by maternal hardships

Table 3 Differences in mean birth weight (grams) and 95% CI associated with exposure to log₂-chemicals and maternal hardships, as selected by elastic net, among the MIREC study participants in Canada, 2008–2011

	Unadjusted	Adjusted for covariates^a
Organochlorine Compounds (OCs)
trans-Nonachlor	-66 (-96, -35)	-37 (-65, -8)
Metals
Lead	-56 (-92, -21)	-38 (-68, -8)
Maternal Hardships
Racially minoritized background	-145 (-208, -83)	-78 (-130, -26)
Low education	-78 (-164, 9)	-103 (-185, -21)
Low supplemental folic acid intake (< 400\(u\)g/day)	-97 (-205, 12)	-61 (-152, 31)

^aAll models were adjusted for gestational age, race and ethnicity, education, age, BMI, smoking, parity, and baby sex. The OC models also adjusted for total lipids. Models assessing hardship of low education and racially minoritized background did not adjust for education and race and ethnicity, respectively, as a covariate
