From: Very low-level prenatal mercury exposure and behaviors in children: the HOME Study
Comparison of different regression models on association between prenatal mercury [log2-transformed] concentrations and BASC-2 scores through 2–8 years. Mean prenatal mercury concentrations defined as a mean of maternal mercury concentrations at 16-weeks, 26-weeks of gestation, delivery, and cord blood mercury concentrations. Unadjusted model was not adjusted for any variables. “Adjusted for fish intake” model was adjusted only for fish intake. Multivariable model 1 was adjusted for maternal age at delivery (≤ 30 years and > 30 years), maternal ethnicity (white and others), annual household income (> $40,000 and ≤ $40,000), maternal education (Completed Bachelor’s degree and not completed bachelor’s degree), marital status at baseline (Married/living with partner vs. unmarried/living alone), HOME score (≥ 40 or < 40), maternal depression during pregnancy (≤ 13 and > 13), child sex, child blood lead concentrations (mean of child blood lead levels at 12, 24, 36, 48, and 60 months), pre-natal serum cotinine concentrations (mean of 16 weeks, 26 weeks, birth and cord levels) and post-natal child blood mercury concentrations (mean of child blood mercury levels at 2, 3, 4, 5 years). Multivariable model 2 was adjusted for all the variables included in model 1 and fish intake
