A controlled evaluation of the WHO Safe Communities model approach to injury prevention: increasing child restraint use in motor vehicles.

Objective: To measure the effect of the WHO Safe Communities model approach to increasing child restraint use in motor vehicles. Design: Pre- and post-intervention observations of restraint use in motor vehicles in several sites in the target area, and in a comparison area community. Setting: Community; southeast Dallas, Texas, 2003--2005. Interventions: A multifaceted approach to increasing use of child safety seats, booster seats and seat belts that included efforts in schools, day care centres, neighbourhoods and a local public clinic, along with child safety seat classes and a low-cost distribution programme. Main outcome measures: Prevalence of restraint use among children 0e8 years old riding in motor vehicles. Results In the target area, the adjusted child restraint use increased by 23.9 percentage points versus 11.8 in the comparison area (difference 12.1; 95% CI 9.9 to 14.3), and adjusted driver seat belt use increased by 16.3 percentage points in the target area versus 4.9 in the comparison area (difference 11.4; 95% CI 11.0 to 11.7). Multivariable multilevel analysis showed that the increase in the target area was significantly greater than in the comparison area for child restraint use (OR 1.6; 95% CI 1.2 to 2.2), as well as for driver seat belt use and proportion of children riding in the back seat. Conclusions: The Safe Communities approach was successful in promoting the use of child restraints in motor vehicles through a multifaceted intervention that included efforts in various community settings, instructional classes and child safety seat distribution.
