Insights
Excessive daily television (TV) watching and TV on during meals in toddlers are linked to unhealthy dietary practices, including more sugar-sweetened beverages and junk food. Limiting TV exposure is crucial for promoting healthier eating habits in young children.
Area of Science:
- Pediatric Nutrition
- Childhood Development
- Public Health
Background:
- Limited research exists on screen time's impact on toddler diets.
- This study focuses on the association between television (TV) exposure and dietary habits in 2-year-olds.
Purpose of the Study:
- To evaluate the relationship between TV exposure and dietary practices in toddlers.
- To assess the impact of daily TV watching time and mealtime TV on children's food choices.
Main Methods:
- Cross-sectional, secondary data analysis from the Greenlight Intervention Study.
- Caregiver reports of toddlers' TV watching habits and dietary practices at 24 months.
- Regression models adjusted for sociodemographic and household factors.
Main Results:
- Higher daily TV watching correlated with increased consumption of sugar-sweetened beverages, fast food, and junk food.
- TV on during mealtimes significantly increased odds of consuming unhealthy foods (aORs ranging from 2.83 to 4.25).
- Lower TV exposure was associated with higher fruit and vegetable intake.
Conclusions:
- Increased TV exposure and mealtime TV are linked to poorer dietary practices in toddlers, particularly in minoritized and low-socioeconomic status populations.
- Findings support American Academy of Pediatrics screen time guidelines.
- Early counseling on TV habits and mealtime routines is recommended.
Background:
While several studies examine the relationship between screen time and dietary practices in children and teenagers, there is limited research in toddlers. This study evaluates the association between television (TV) exposure and dietary practices in 2-year-old children.
Methods:
We conducted a cross-sectional, secondary data analysis from the Greenlight Intervention Study. Toddlers' daily TV watching time, mealtime TV, and dietary practices were assessed by caregiver report at the 24-month well-child visit. Separate regression models were used and adjusted for sociodemographic/household characteristics and clinic site.
Results:
Five hundred and thirty-two toddlers were included (51% Latino; 30% non-Latino Black; 59% ≤$20,000 annual household income). Median daily TV watching time was 42 minutes (interquartile range: 25, 60); 25% reported the TV was "usually on" during mealtimes. After adjustment, toddlers who watched more TV daily had higher odds of consuming sugar-sweetened beverages, fast food, and more junk food; those watching less TV had higher odds of consuming more fruits/vegetables. Those with the TV "usually on" during mealtimes were more likely to consume sugar-sweetened beverages (aOR 3.72 [95% confidence interval {CI} 2.16-6.43]), fast food (aOR 2.83 [95%CI 1.54-5.20]), and more junk food (aOR 4.25 [95%CI 2.71-6.65]).
Conclusions:
Among toddlers from primarily minoritized populations and of lower socioeconomic status, those who watched more TV daily and usually had the TV on during meals had significantly less healthy dietary practices, even after adjusting for known covariates. This study supports the current American Academy of Pediatrics screen time guidelines and underscores the importance of early counseling on general and mealtime TV.
