Associations ^a between gestational and trimester-specific mean concentrations of atrazine in drinking water and term LBW among AMP communities with verified service boundaries (n = 10) in Ohio, 2006–2008.

Exposure	Model	n	OR ^b (95% CI)
Gestational mean	Crude	3929	1.04 (0.62, 1.72)
Gestational mean	Adjusted	3929	1.16 (0.77, 1.74)
First trimester	Crude	3961	1.13 (0.96, 1.33)
First trimester	Adjusted	3961	1.17 (1.03, 1.34)
Second trimester	Crude	3961	0.95 (0.77, 1.17)
Second trimester	Adjusted	3961	1.01 (0.83, 1.22)
Third trimester	Crude	3961	0.96 (0.66, 1.40)
Third trimester	Adjusted	3961	1.01 (0.72, 1.41)

^a Term low birth weight is defined as <2500 g among term births (≥37 weeks’ gestation). All adjusted models included maternal race/ethnicity, maternal age, birth year, infant sex, maternal education, WIC status, marital status, maternal smoking status, and maternal pre-pregnancy BMI. ^b Odds ratios reflect increase in odds per 1 µg/L increase in atrazine in drinking water.
