Adjusted associations between maternal UIC and infant HAZ, WAZ, and BMI, using multiple linear regression^c

Maternal UIC	HAZa		WAZb
	Adjusted coefficient	P value	Adjusted coefficient	P value
< 50 μg/L	Reference		Reference
50–99 μg/L	0.965	0.076	0.918	0.011
100–199 μg/L	0.794	0.121	0.671	0.038
200–299 μg/L	0.524	0.424	0.779	0.031
> 299 μg/L	0.795	0.208	0.800	0.027

^aIndependent variables entered in the regression were maternal UIC, maternal age, education, occupation, and income, and maternal and parental height. Dependent variable was infant HAZ

^bIndependent variables entered in the regression were maternal UIC, maternal age, education, occupation, and income, and maternal BMI. Dependent variable was infant WAZ

^cOnly women whose children had UIC within the normal range (50-299 μg/L) were included (n = 450)
