AAP Updates Recommendations on Car Seats for Children

The American Academy of Pediatrics is publishing updated
recommendations on car safety seats, but the real-world impact on how parents
should use the seats in vehicles will be minimal.

In the updated policy statement, “Child Passenger Safety,”
and an accompanying technical report, to be published in the November 2018
issue of Pediatrics (published online Aug. 30), the AAP recommends
children remain in a rear-facing car safety seat as long as possible, until
they reach the highest weight or height allowed by their seat. Previously, the
AAP specified children should remain rear-facing at least to age 2; the new recommendation
removes the specific age milestone.

“Fortunately, car seat manufacturers have created seats that
allow children to remain rear-facing until they weigh 40 pounds or more, which
means most children can remain rear-facing past their second birthday,” said
Benjamin Hoffman, MD, FAAP, lead author of the policy statement and chair of
the AAP Council on Injury, Violence and Poison Prevention. “It’s best to keep
your child rear-facing as long as possible. This is still the safest way for
children to ride.”

The prior recommendation to keep children rear-facing to age
2 was based in part on a study that found lower risks of injury among children
ages 1 to 2 years who were rear-facing. That data was supported by biometric
research, crash simulation data and experience in Europe where children ride
rear facing for longer periods.

However, in 2017, questions arose about the original study,
and it was retracted by the journal Injury Prevention. A re-analysis of
the data found that while rear-facing still appeared to be safer than
forward-facing for children younger than 2, the injury numbers were too low to
reach statistical significance. The AAP decided to update its recommendations
to reflect how the science has evolved.

“Car seats are awesome at protecting children in a crash,
and they are the reason deaths and injuries to children in motor vehicle
crashes have decreased,” Dr. Hoffman said. “But that also means we just don’t
have a large enough set of data to determine with certainty at what age it is
safest to turn children to be forward-facing. If you have a choice, keeping
your child rear-facing as long as possible is the best way to keep them safe.”

When a child rides rear-facing, the head, neck, and spine
are all supported by the hard shell of the car safety seat, allowing the car
seat to absorb most of the crash forces, and protecting the most vulnerable
parts of the body. When children ride forward-facing, their bodies are
restrained by the harness straps, but their heads – which for toddlers are
disproportionately large and heavy – are thrown forward, possibly resulting in
spine and head injuries.

Parents often look forward to transitioning from one stage
or milestone to the next. In car seats, this is one area where transitions are
not “positive,” and where delaying transitions is best, according to the AAP.
Each transition – from rear-facing to forward-facing, from forward-facing to
booster seat, and from booster seat to seat belt alone – reduces the protection
to the child.

Parents should check the instruction manual and the labels
on a car safety seat to find the manufacturer’s weight and height limits. When
a child is approaching one of those limits, it is time to think about
transitioning to the next stage.

The AAP recommends:

  • Infants
    and toddlers should ride in a rear-facing car safety seat as long
    as possible, until they reach the highest weight or height allowed by
    their seat. Most convertible seats have limits that will allow children to
    ride rear-facing for 2 years or more.

  • Once
    they are facing forward, children should use a forward-facing car
    safety seat with a harness for as long as possible, until they reach
    the height and weight limits for their seats. Many seats can accommodate
    children up to 65 pounds or more.

  • When
    children exceed these limits, they should use a belt-positioning
    booster seat until the vehicle’s lap and shoulder seat belt fits
    properly. This is often when they have reached at least 4 feet 9 inches in
    height and are 8 to 12 years old.

  • When
    children are old enough and large enough to use the vehicle seat belt alone,
    they should always use lap and shoulder seat belts for optimal

  • All
    children younger than 13 years should be restrained in the rear seats
    of vehicles for optimal protection.

Most important is to use a car seat for every trip, Dr.
Hoffman said. Using the right car safety seat or booster seat lowers the risk
of death or serious injury by more than 70 percent.

“Car crashes remain a leading cause of death for children.
Over the last 10 years, 4 children under 14 and younger died each day. We hope
that by helping parents and caregivers use the right car safety seat for each
and every ride that we can better protect kids, and prevent tragedies,” said
Dr. Hoffman.
