Does wearing helmets reduce motorcycle-related death? A global evaluation

BACKGROUND: The high risk of injury and death of motorcycle riders is a major global health problem. This study aimed to evaluate the effect of helmet wearing on motorcycle riders' death rates on a global level. METHODS: Data for motorcycle riders were collected from 70 countries. These data included motorcycle-related death rates per 100,000 population, helmet non-usage percentage, Gross National Income per capita (GNI), number of registered motorized 2-3 wheelers, the effectiveness of law enforcement in each country, and whether there was standards for helmets use or not. Correlations between studied variables were done using Pearson correlation. Multiple linear regression models were used to define factors affecting motorcycle-related death rates. RESULTS: The correlation between motorcycle-related death rate and helmet non-usage, was almost significant (p=0.056, r=0.28). Helmet non-usage percentage was significantly correlated with GNI (p Language: en
