Interventions to increase children's booster seat use: a review

Area of Science:

• Pediatric Safety
• Traffic Injury Prevention
• Public Health Interventions

Background:

• Booster seats significantly reduce injury risk by 59% in children aged 4-8 during motor vehicle crashes.
• Despite proven safety benefits, booster seat utilization remains low among the target age group.
• Public health and traffic safety agencies recommend booster seats for children until vehicle seat belts fit properly.

Purpose of the Study:

• To evaluate the effectiveness of interventions designed to increase booster seat usage in children aged 4 to 8 years.
• To synthesize evidence from rigorous study designs to inform public health strategies.
• To identify which intervention components are most successful in promoting booster seat adoption.

Main Methods:

• A systematic review using Cochrane methodology was conducted to assess intervention effects.
• Searches included online databases, reference lists, journals, and expert consultations, concluding in 2005.
• Included studies comprised randomized controlled trials and controlled before-and-after studies.

Main Results:

• Five studies involving 3070 participants met the inclusion criteria.
• Interventions generally demonstrated effectiveness in increasing booster seat use.
• Combinations of education with incentives or free booster seat distribution yielded more consistent positive results than education alone.

Conclusions:

• Incentives and free booster seat distribution, when paired with educational components, effectively increase booster seat usage.
• Targeted interventions are crucial for improving child passenger safety.
• Evidence supports the implementation of combined educational and incentive-based programs to enhance booster seat adoption.
