Table 2 Mean ± SD externalizing SCBE T-scoresa at baseline, according to baseline correlates

From: Externalizing behavior is prospectively associated with intake of added sugar and sodium among low socioeconomic status preschoolers in a sex-specific manner

  1. aHigher T-scores on the SCBE indicate lower levels of externalizing behavior
  2. bFrom a linear mixed effects model with externalizing SCBE T-score as the outcome and a continuous variable for each ordinal sociodemographic predictor. For nominal categorical variables, a type III F test was used. A random intercept was specified to account for clustering by classroom
