Rates of advance directive completion have increased over the past decade, but significant race differences remain. This study examined how overall increases in advance directive completion have affected disparities between White and African American older adults.
Data were taken from the Health and Retirement Study (HRS). Using logistic regression models, the odds of having an advance directive among a sample of older African Americans and Whites who died between 2001 and 2012 were compared ( N = 5,832).
Odds for African Americans were 16% of the odds for Whites, p < .001, 95% confidence interval (CI) = [0.11, 0.23]. There were no significant interactions between race and year of death before 2010. During 2010-2012, the increase in the odds for African Americans was greater than for Whites, odds ratio (OR) = 1.95, p = .02, 95% CI = [1.14, 3.35].
Although race disparities remain, the gap between Whites and African Americans has begun to narrow.
在过去十年中，预立医疗指示的完成率有所提高，但种族差异仍然显著。本研究探讨了预立医疗指示完成率的总体上升如何影响美国白人和非裔美国老年人之间的差异。
数据取自健康与退休研究（HRS）。使用逻辑回归模型，比较了2001年至2012年间死亡的老年非裔美国人和白人样本中拥有预立医疗指示的几率（N = 5832）。
非裔美国人的几率是白人的16%，p <.001，95%置信区间（CI） = [0.11, 0.23]。2010年之前，种族与死亡年份之间没有显著的交互作用。在2010 - 2012年期间，非裔美国人几率的增加大于白人，优势比（OR） = 1.95，p =.02，95% CI = [1.14, 3.35]。
尽管种族差异仍然存在，但白人和非裔美国人之间的差距已开始缩小。
