Background: Light motorcycles (LMCs, with cylinder capacities between 50 to 250cc) are popular for commuting in developing countries. Objectives: With increasing LMC casualties in Taiwan, we conducted a multicenter study to analyze the effects of riders’ psycho-cognitive factors on injury severity. Methods: Riders who were hospitalized upon LMC crashes were contacted. Information of riders’ demographics and psycho-cognitive factors were collected via questionnaire and linked to hospital data. Injury Severity Score (ISS) and Length of Hospitalization (LOH) were applied as injury severity indicators. Results: Totally 725 patients completed their questionnaires. The mean age was 37.7 years and 64% of the patients were male. The multivariate analyses showed age≧65 (Odds ratio: 3.75, 95% confidence interval: 1.99–7.09, P valve: <0.0001), alcohol/ stimulating refreshments consumption (2.34, 1.09-5.03, 0.029) and fatigue riding (1.86, 1.00-3.43, 0.049) were significant risk factors for ISS ≥ 9. For increased LOH, age between 18-24 and ≥ 65 year-old (Standardized β coefficient: 0.09, P valve: 0.036 and 0.13, 0.002 respectively), psychiatric disease (0.08, 0.038) and alcohol/ stimulating refreshments consumption (0.11, 0.005) were significant risk factors. However, motorcycle crashes due to distraction by roadside scenery or activity resulted in a shorter LOH (-0.08, 0.049). Discussion, Conclusions and Implications: Certain riders’ psych-cognitive factors were significantly associated with injury severity after LMC crashes and related medical resources consumption in Taiwan. Namely LMC crashes have risk factors of injury severity not similar to those of heavy motorcycles in developed countries and deserve more attention for injury prevention. A further in-depth evaluation of such significant risk factors should yield valuable information to reduce severe injuries after LMC crashes.
