Abstract：
BACKGROUND: Almost one-third of the U.S. military population is comprised of service members and veterans (SMVs) of color. Research suggests poorer functional and psychosocial outcomes among Black and Hispanic/Latine vs. White civilians following traumatic brain injury (TBI).
OBJECTIVE: This study examined racial/ethnic differences in 5-year functional independence and life satisfaction trajectories among SMVs who had undergone acute rehabilitation at one of five Veterans Affairs (VA) TBI Model Systems (TBIMS) Polytrauma Rehabilitation Centers (PRCs).
METHODS: Differences in demographic and injury-related factors were assessed during acute rehabilitation among White (n = 663), Black (n = 89), and Hispanic/Latine (n = 124) groups. Functional Independence Measure (FIM) Motor, FIM Cognitive, and Satisfaction with Life Scale (SWLS) scores were collected at 1, 2, and 5 years after injury. Racial/ethnic comparisons in these outcome trajectories were made using hierarchical linear modeling.
RESULTS: Black SMVs were less likely than White and Hispanic/Latine SMVs to have been deployed to a combat zone; there were no other racial/ethnic differences in any demographic or injury-related variable assessed. In terms of outcomes, no racial/ethnic differences emerged in FIM Motor, FIM cognitive, or SWLS trajectories.
CONCLUSIONS: The absence of observable racial/ethnic differences in 5-year outcome trajectories after TBI among SMVs from VA TBIMS PRCs contrasts sharply with previous research identifying disparities in these same outcomes and throughout the larger VA health care system. Individuals enrolled in VA PRCs are likely homogenized on key social determinants of health that would otherwise contribute to racial/ethnic disparities in outcome trajectories.

摘要：
背景：几乎三分之一的美国军人由服役人员和退伍军人（SMV）组成。研究表明，黑人和西班牙裔/拉丁裔与创伤性脑损伤（TBI）后的白人平民。
目的：本研究调查了在5个VATBI模型系统（TBIMS）多伤康复中心（PRCs）之一进行过急性康复的SMV的5年功能独立性和生活满意度轨迹的种族/民族差异。
方法：在急性康复期间评估白种人的人口统计学和损伤相关因素的差异（n=663），黑人（n=89）和西班牙裔/拉丁裔（n=124）组。功能独立性测量(FIM)电机,FIM认知,受伤后1年、2年和5年收集生活满意度量表（SWLS）评分。这些结果轨迹中的种族/种族比较是使用分层线性模型进行的。
结果：与白人和西班牙裔/拉丁裔SMV相比，黑色SMV部署到战区的可能性较小；在评估的任何人口统计学或伤害相关变量中，没有其他种族/民族差异。在结果方面,FIM汽车没有出现种族/民族差异，FIM认知，或SWLS轨迹。
结论：来自VATBIMSPRCs的SMV在TBI后的5年结果轨迹中没有可观察到的种族/民族差异，这与先前的研究形成了鲜明的对比，这些研究在这些相同的结果中以及整个更大的VA医疗保健系统中的差异。参加VAPRC的个人可能在健康的关键社会决定因素上同质化，否则会导致结果轨迹中的种族/族裔差异。
