Association between externalizing SCBE T-scores at baseline and added sugar and sodium intake at follow-up
| Baseline externalizing SCBE T-scoresa | Added sugar intake, % of Calories | Sodium intake, mg/1000 Calories | ||
|---|---|---|---|---|
| Unadjusted beta (95% CI)b | Adjusted beta (95% CI)b,c | Unadjusted beta (95% CI)b | Adjusted beta (95% CI)b,c | |
| Boys | ||||
| Per 5-points lower T-score (more externalizing behaviors) | 0.5 (0.1, 0.9) | 0.6 (0.2, 1.1) | −19 (−41, 3) | −22 (−45, 1) |
| P value | 0.008 | 0.004 | 0.09 | 0.06 |
| Girls | ||||
| Per 5-point lower T-score (more externalizing behaviors) | −0.5 (−0.9, −0.1) | −0.6 (−1.0, −0.1) | 28 (8, 49) | 24 (1, 46) |
| P value | 0.03 | 0.01 | 0.007 | 0.04 |
aHigher number of externalizing behaviors is equivalent to a lower T-score
bFrom a linear mixed effects regression model with continuous added sugar (% of Calories) or sodium intake (mg/1000 Calories) as the outcome and continuous externalizing SCBE T-scores as the predictor, expressed per 5 points. The model also accounted for total energy intake at follow-up. A random intercept was specified to account for clustering by classroom
cAdjusted for race/ethnicity, quartiles of income-to-needs ratio, and overweight/obese status at baseline as potential confounders
