May 7, 2008 -- The safest spot for a baby's car seat is in the center of the
back seat rather than on the sides, according to a new study.
Although older passengers using seat belts can decide where they sit in a
car, researchers point out that a child's seat is determined by where the
child-restraint system is installed. For ease of access and keeping an eye on a
baby, the most common spot for a baby's car seat is the rear passenger
But the study showed that children under age 3 seated in the center of the
back seat had nearly half the risk of injury in motor vehicle crashes than
children seated in either of the other positions.
"The center rear seating position is used less often by children
restrained by a child-restraint system as they get older," writes
researcher Michael J. Kallan, MS, University of Pennsylvania School of
Medicine, and colleagues in Pediatrics. "Children seated in the
center rear have a 43% lower risk of injury compared with children in a rear
Researchers say current child restraint safety guidelines recommend the
center position as long as a snug fit of the car seat can be achieved. But
those recommendations are based on research that was conducted a decade
Center Seat Safest for Children
In this study, researchers looked at whether those recommendations were
still valid by analyzing data on child occupants of motor vehicle accidents
from 1998 to 2006 based on insurance claims and a telephone survey.
The analysis included children from birth to age 3 who were seated in a
child-restraint system in the rear seat of motor vehicles (model year 1990 or
newer) that were involved in a crash in 16 states.
The results showed that the passenger side rear seat was the most popular
position for the baby or child's car seat (41%) followed by the left (driver's
side) rear seat (31%) and center seat (28%).
Researchers also found use of the center position decreased as the child got
older. For example, 39% of baby car seats for infants under age 1 were placed
in the center rear seat vs. 18% of child car seats for 3-year-olds, regardless
of any additional passengers in the rear seat.
