WHAT'S KNOWN ON THIS SUBJECT: Several studies suggest that excessive media use in early childhood predicts poorer developmental outcomes. It has not been studied whether infants with self-regulation problems, who may be at higher developmental risk, develop excessive media use habits.
WHAT THIS STUDY ADDS:This study shows that infants and toddlers with self-regulation difficulties (ie, problems with selfsoothing, sleep, emotional regulation, and attention) view more media at 2 years of age, independent of other important confounders.abstract OBJECTIVES: Examine prospective associations between parentreported early childhood self-regulation problems and media exposure (television and video viewing) at 2 years. We hypothesized that children with poor self-regulation would consume more media, possibly as a parent coping strategy.
METHODS:We used data from 7450 children in the Early Childhood Longitudinal Study-Birth Cohort. When children were 9 months and 2 years old, parents completed the Infant Toddler Symptom Checklist (ITSC), a validated scale of self-regulation. With daily media use at 2 years as our outcome, we conducted weighted multivariable regression analyses, controlling for child, maternal, and household characteristics.
RESULTS:Children watched an average of 2.3 hours per day (SD 1.9) of media at age 2 years. Infants with poor self-regulation (9-month ITSC score $3) viewed 0.23 hour per day (95% confidence interval [CI] 0.12-0.35) more media at 2 years compared with those with 9-month ITSC score of 0 to 2; this remained significant in adjusted models (0.15 hour per day [95% CI 0.02-0.28]). Children rated as having persistent self-regulation problems (ITSC $3 at both 9 months and 2 years) were even more likely to consume media at age 2 (adjusted b 0.21 hour per day [95% CI 0.03-0.39]; adjusted odds ratio for .2 hours per day 1.40 [95% CI 1.14-1.71]). These associations were slightly stronger in low socioeconomic status and English-speaking households.
