Safer bicycling for 9–12-year-olds with parent support

A cluster randomized trial to improve adolescent bicycling safety

NIH-funded research University of Iowa · NIH-11174394

What this research studies

If you join, your 9–12-year-old and a parent would enroll through local after-school or summer programs and your site would be randomly assigned to one of three groups. All participating bikes get a Pedal Portal GPS/video unit that records routes, hours ridden, and safety-relevant events like near-crashes and crashes. Some sites will offer a community-based bicycle safety class for kids, and some will also include an in-person parent training session to teach how to support safe riding. Researchers will use the on-bike data to compare riding exposure and safety behaviors across the three groups during the study.

Who could benefit from this research

Good fit: Ideal candidates are children aged 9–12 who regularly ride a bicycle and a parent or guardian willing to participate, typically recruited from local neighborhood centers or after-school programs.

Not a fit: Children who do not ride bikes, or families unable or unwilling to attend parent training or use the bike-mounted device, may not receive benefit from this program.

Why it matters

Potential benefit: If successful, this could teach safer riding skills and reduce near-crashes and injuries among young bicyclists.

How similar studies have performed: Many bike-safety education programs exist but few have shown clear behavior-change benefits, and combining parent training with on-bike GPS/video monitoring is a relatively new approach.
