Flooring, beds and football top list of products/activities that cause traumatic brain injuries in children

Most nonfatal TBIs in children are the result of falls, motor vehicle crashes, being struck by a moving or stationery object, and assault. Football was the leading cause of TBIs among 15- to 19-year-olds.

Among 10- to 14-year-olds, the first five causes of traumatic brain injuries involved sports or recreational activities.

Almost three-quarters of the nonfatal traumatic head injuries (TBIs) that send children and teens in the United States to hospital emergency rooms each year are linked in some way with everyday consumer products, especially beds and flooring, or to sports and recreational activities, especially football and bicycling, according to a study published this week in the journal Brain Injury.

“In most cases, infants and children are safe in bed and when playing sports outside, but our study highlights some of the risks and the priorities in different age groups for preventing serious head injuries,” says Bina Ali, the study’s lead author and a research scientist at the Pacific Institute for Research and Evaluation, in a released statement.

Traumatic brain injury, or TBI, occurs when a sudden bump, blow, jolt or penetrating wound to the head damages the brain. About 2.8 million Americans experience a TBI each year, including 812,000 children aged 17 or younger, according to government estimates.

Traumatic brain injuries are a leading cause of disability in the United States. Children who survive a TBI can have subsequent neurological problems that affect their memory and thinking skills and that increase their risk for developing behavioral problems.

TBIs are also a leading cause of deaths in the United States. Each year, the injuries contribute to the deaths of 56,800 Americans, including more than 2,500 children.

The greatest risk

Most nonfatal TBIs in children are the result of falls, motor vehicle crashes, being struck by a moving or stationery object, and assault. The current study was undertaken to see which of the thousands of products regulated by the U.S. Consumer Product Safety Commission (CPSC) are most likely to be involved in these injuries at different ages during childhood. CPSC-regulated items include sports and recreational equipment, such as football helmets and bicycles, but not cars and firearms, which are regulated by other government agencies.

The researchers used CPSC data collected from a large representative sample of hospital emergency departments across the country from 2010 through 2013. Based on that data, they estimated that 4.1 million children and teens were at emergency departments for non-fatal TBIs during those four years.

CPSC-regulated products were associated with 72 percent of the hospital visits. More than a quarter of the injuries — 28.1 percent — were linked to equipment used in sports and recreational activities, 17.2 percent to home furnishings (such as beds), and 17.1 percent to home structures and building materials (such as stairs and flooring). Much smaller percentages of the injuries were tied to child nursery equipment (such as baby strollers, high chairs and baby changing tables) (2.7 percent) and toys (2.4 percent), as well as various other products.

Leading causes by age

The top 10 leading products and activities contributing to the TBIs were the following:

  • floors
  • beds
  • football
  • stairs
  • bicycles
  • basketball
  • ceilings and walls
  • chairs
  • soccer
  • tables

Among infants under a year old, the leading cause of TBIs was a fall from a bed (25.4 percent of all the injuries), followed by falls on slippery or uneven flooring (14 percent) and from sofas (7.4 percent) and stairs (6.2 percent).

Car seats were fifth on the list (4.6 percent). “When car seats are used outside of the car as baby carriers and are handled inappropriately, they can pose a risk of TBI,” Ali and her co-authors explain in the study. “For example, if a car seat is placed on a high surface, such as a table or countertop, there is a risk of the car seat falling off the surface and injuring the infant.”

Among toddlers aged 1 to 4 years, stairs accounted for 9.9 percent of the injuries, followed by flooring and beds at 9.7 percent each. Bunk beds were particularly dangerous for this age group, the study found.

At older ages, the causes of TBIs were more likely to be found outside the home. Among 5- to 9-year-olds, flooring led the list (6.1 percent), but bicycles were next (5.2 percent). And among 10- to 14-year-olds, flooring dropped to sixth on the list. The first five causes of TBIs in this age group involved sports or recreational activities: football (13.7 percent), basketball (6.4 percent), bicycles (5.4 percent), soccer (4.8 percent) and baseball/softball (4.4 percent).

Football was also the leading cause of TBIs among 15- to 19-year-olds, followed by basketball (4.8 percent), soccer (3.8 percent) and bicycles (3.0 percent).

The list for older teens — 15- to 19-year-olds — was also dominated by sports and recreational activities, with football (8.8 percent) and basketball (4.8 percent) once again at the top.

Limitations and implications

The study is based on national estimates and includes only TBIs treated at hospital emergency departments. It does not include head injuries treated at urgent care clinics, doctors’ offices or school health clinics.

Nor does it identify the severity of the injuries associated with different products and activities.

Still, the findings should help policymakers develop priorities for TBI prevention programs, the study’s authors write.

The findings can also help parents take actions to reduce hazards in their home. “Simple measures such as removing trip hazards, using stair gates and guard rails, avoiding hard surface playgrounds and wearing helmets could help reduce the risk of injury,” says Ali.

Although, as other research has shown, football and other sports-related helmets offer protection against severe skull fractures, but they cannot prevent concussions.
