Toddlers who watched more TV were significantly more likely than those who watched less TV to consume sugar-sweetened drinks and junk foods, based on data from 529 children.
Previous research had shown an association between screen time and poor diet, but most have involved school-aged children; the relationship in toddlers has not been well studied, Melissa R. Lutz, MD, of Johns Hopkins University, Baltimore, said in a presentation at the Pediatric Academic Societies annual meeting.
The American Academy of Pediatrics currently recommends no digital media for children younger than 18-24 months, and an hour or less daily for children aged 2-5 years.
To examine the association between TV time and dietary practices in 2-year-olds, the researchers conducted a secondary analysis of data from 529 children who presented for their 2-year-old well-child visit at a single center. The study population was 52% Latino/Hispanic and 30% non-Latino/Hispanic Black, and 69% had an annual household income less than $20,000. The median time spent watching TV daily was 42 minutes. The data were taken from participants in the Greenlight Intervention Study, a randomized trial of an obesity prevention program at four academic pediatric primary care clinics in the United States.
Daily screen time and dietary practices were based on parent reports, and included daily volume of juice, daily counts of fruits and vegetables, daily count of junk foods such as chips, ice cream, French fries, and fast food, and consumption of sugar-sweetened beverages.
