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 covariatesa | |
|---|---|---|
| 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 (< 400g/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
