Interpersonal violence and traumatic brain injuries among Native Americans and women.

OBJECTIVES

This study aimed to assess the odds of experiencing a traumatic brain injury (TBI) as a result of interpersonal violence (IPV) among Native Americans compared to other races controlling for gender, age, socioeconomic status, rurality and intoxication at the time of the injury.

METHODS

A secondary data analysis of the Arizona Trauma Database consisting of 18 944 cases of TBI between 2008-2010 throughout the state of Arizona was conducted. There were 312 patients who experienced injuries caused by IPV in the sample. Descriptive statistics, cross-tabulations, bivariate analyses and a logistic regression model were used for analyses.

RESULTS

The logistic regression model found that Native Americans (OR = 1.15), patients from the other race category (OR = 1.18), females (OR = 1.35) and those who were insured (OR = 1.26) had higher odds of experiencing a TBI as a result of IPV. Rurality and intoxication were mediators of the correlation between Native American race and TBI as a result of IPV.

CONCLUSIONS

Native Americans are more likely than Whites and females are more likely than males to experience TBIs as a result of IPV.
