Findings of our study may not be applicable to other geographic
areas. Nearly 50% of the Los Angeles County population is Hispanic,
compared to 17% nationwide. In addition, in California, a greater
percentage of the population lives below the poverty level. Multiple
studies have found that helmet use in the Hispanic population is
significantly lower than in other racial/ethnic groups [10,11,20,30].
Our study underscores the importance of targeting these specific
communities and racial/ethnic groups for injury prevention programs.
In addition, as a large metropolitan area with significant diversity, our
results actually highlight groups that are not well represented in other
parts of the country.
