Table 2.
Relation of mild cognitive impairment and Alzheimer's disease to risk of death in all persons and racial subgroups*
| All Persons | African Americans | Whites | |
|---|---|---|---|
| Diagnosis | HR (95% CI) | HR (95% CI) | HR (95% CI) |
| Mild cognitive impairment | 1.48 (1.22,1.80) | 1.40 (1.04,1.88) | 1.57 (1.22,2.02) |
| Alzheimer's disease | 2.84 (2.29, 3.52) | 2.59(1.88,3.59) | 3.20 (2.40, 2.47) |
| Other dementia** | 2.69 (1.49,4.86) |
*
From proportional hazards models that controlled for age, sex, and education and either controlled for or stratified by race. HR indicates hazard ratio and CI indicates confidence interval.
**
There were too few cases of other dementia to estimate risk in racial subgroups.
