Health Risk Aspects and Comfort of Infants in Infant Seats for Cars

Infant safety seats--the child safety seats for the youngest children, from newborn up to 13 kg--have saved many lives since they became available in Sweden in the beginning of the 80s. Since then the question has been if there are any long-term health effects on infants in car seats. The purpose of this study was to describe the basis for the statements regarding long-term health effects of letting infants sit longer periods in infant safety seats. To find out more about the vibrational environment and comfort in infant seats, vibration measurements were performed on infant safety seats installed in three different ways. A literature review and interviews with pediatricians, nurses and physiotherapists show that a recommendation including a specified time is not relevant. Vibration measurements show that the infant safety seats in contrast to automobile seats amplify vibrations with frequencies between 1 and 25 Hz.
