E10-02 - Childhood behavioral and emotional characteristics are associated with soda intake during adolescence: a prospective study in Mexico City

Objectives: To evaluate whether behavioral and emotional characteristics assessed during childhood would be associated with soda intake during adolescence in a Mexico City cohort.

The study population includes 394 Mexico City adolescents enrolled in a birth cohort study with complete information on behavior and prospective soda intake. In 2008, when children were between 6 and 12 years (y) of age, the Behavioral Assessment System for Children BASC Third Edition was administered to parents and to a subset of participants (analytic sample for self-report=252). Composite age- and sex-standardized T-scores for parent-report included adaptive skills, behavioral symptoms index, externalizing problems, and internalizing problems, while composite T-scores for self-report included emotional symptoms, inattention/hyperactivity, internalizing problems, personal adjustment, and school problems. Sugar-sweetened soda intake was measured during a follow-up visit when children were between 9 and 17 y of age by a food frequency questionnaire, and reported in mL/day intake. We used separate linear regression models with soda intake as the continuous outcome and each behavioral score as a continuous predictor to obtain Beta estimates, 95% confidence intervals (CI) and P-values, adjusting for socioeconomic status and mother's marital status.

At baseline, the mean age was 8.3 ± 1.3 y, and 49% were male. The median soda intake was 180 mL/day (IQR=34, 257) at follow-up. Parent- and self-reported composite T-scores indicative of more negative behavior and emotions (typically higher scores) during childhood were related to higher adolescent soda intake. Of the parent-reported composite measures, the strongest predictor of soda intake was internalizing problems (confounder-adjusted Beta=4.7 mL, 95% CI: 1.7, 7.7). Among the self-reported composite scores, the strongest predictors were internalizing problems (adjusted Beta=6.7 mL, 95% CI: 1.8, 11.5) and school problems (adjusted Beta=8.0 mL, 95% CI: 3.5, 12.4).

Parent- and self-reported behavior and emotion measures in childhood were associated with soda consumption in adolescence. Mexican children with higher perceived levels of internalizing problems may be particularly vulnerable to excessive soda intake.
