Regression coefficients for cord blood metal concentrations in relation to height SDS at respective age
| Participants | Metal | Height SDS at 2 years of age | Height SDS at 3 years of age | Height SDS at 4 years of age |
|---|---|---|---|---|
| β (95% CI) | β (95% CI) | β (95% CI) | ||
| N = 278 | Mn | −0.03(−0.55, 0.49) | −0.15 (−0.43, 0.14) | −0.03 (−0.56, 0.51) |
| Pb | −0.17 (−0.57, 0.24) | −0.10 (−0.32, 0.12) | −0.25 (−0.67, 0.17) | |
| Se | 0.54 (−0.63, 1.70) | 0.03 (−0.61, 0.67) | 0.59 (−0.62, 1.79) | |
| Hg | −0.05 (−0.33, 0.23) | 0.08 (−0.08, 0.23) | −0.14 (−0.44, 0.15) | |
| Cd | −0.45 (−0.90, 0.01) | −0.29 (−0.55, −0.04) | −0.12 (−0.59, 0.35) |
Note: Models were adjusted for maternal age, prepregnancy body mass index, alcohol consumption and smoking status, hypertensive disorders of pregnancy, gestational diabetes mellitus, diabetes mellitus, income, and education
Log2-transformed metal concentrations were used for the models
Cd: Cadmium; Hg: Mercury; Mn: Manganese; Pb: Lead; Se: Selenium; CI: Confidence interval; SGA: Small for gestational age; SDS: Standard deviation score
