Results are from linear regression models, which were adjusted for the length of the pregnancy, newborn sex, ethnicity by birth place, recruitment site, age, education, parity, pre-pregnancy BMI, and ever smoking status. A log2-transformation was applied to hair arsenic. Results are therefore expressed as the difference in GWG (in kg) for a doubling in hair arsenic concentration.
