aExtrnal cause of injury is based on E-codes
bAge-adjusted hospitalization rates are based on age-specific hospitalization rates per 100,000 population in 10 to 19 age group. Age-adjusted hospitalization rates are computed by the direct method, using as the standard population the age distribution of the total population of the United States for the year 2000. Hospitalization records with missing race, insurance and legislation of interest nformation were excluded from the analysis
