^a Logistic regression was used to predict yes or no answers to a question about whether a subject had anemia or iron deficiency
^b Unadjusted analysis refers to a simple logistic regression with the dependent variable
^c OR odds ratio
^d CI confidence interval
^e Adjusted analysis refers to the covariates that were best able to predict poor health, anemia, and iron deficiency using stepwise regression techniques in a multivariable model
^f Maternal education (1, low; 2, high)
^g Overweight (1, BMI < 85th percentile; 2, BMI ≥ 85th percentile)
*P < 0.05, ** P < 0.01
