The study was published online Monday in the journal Pediatrics.
In 2011, 12,300 children nationwide got emergency room treatment for TV-related injuries, compared with 5,455 in 1990. The injury rate nearly doubled, from 0.85 injuries per 10,000 children aged 17 and younger in 1990 to 1.66 per 10,000 in 2011, the study found.
The researchers examined national data on non-fatal television-related injuries to kids from 1990-2011.
Over those two decades, 215 children died from these injuries, government data show, and news reports indicate that since January 2012, at least six young children have been killed nationwide by falling TVs.
Scott Wolfson, spokesman for the government's Consumer Product Safety Commission, said as flat-screen TVs have become more popular, many families move heavier old TVs to bedrooms, placing them on dressers or other unsteady furniture not designed to hold them.
