Seattle Children's Bicycle Helmet Campaign

Community-wide campaign in Seattle (from 1986) run by a coalition of health, bicycle and helmet-industry groups. It told parents that riding without a helmet is dangerous, cut helmet prices with discount coupons, and worked to make helmets acceptable to children.

Evidence

Quasi-experimentalPositive

Observed helmet use (9,827 child riders) rose from 5.5% to 15.7% in Seattle vs 1.0% to 2.9% in Portland, the control city (DiGuiseppi 1989). By 1992 use reached 40.2%, and bicycle-related head injuries in an HMO population fell about 67% among children aged 5-14 (Rivara 1994, no control).

Research notes

Created 2026-10-22 by OpenAlex literature mining (openalex-deep pass); evidence level, outcome and findings are paraphrased from the evaluation abstracts, full texts not read. No credits: no page naming an agency was checked. Sponsor wording is approximate: the abstracts name only 'a coalition of health, bicycle, and helmet industry organizations'; Harborview's lead role is from secondary knowledge. Channel list is a best guess for a multifaceted campaign; confirm in Bergman 1990. Seattle later passed helmet ordinances (not checked).
