Table 1.
Maternal and newborn demographics associated with positive child health index (PCHI) using a binary classification of PCHI. Logistic regression models for maternal demographics adjusted for child’s sex, gestational age, and birth weight Z-score, and maternal education, public insurance, and race; models for newborn demographics adjusted for maternal education, public insurance, and race. Stratification by race was deemed necessary when the p value for the interaction term between race and the modifiable antecedent was less than 0.1; if that p value was ≥ 0.1, then analysis was not stratified and the interaction term was not included. Odds ratio represents the odds a child would have and disorders over the odds that a child would have no disorders for that demographic
