目的：本文提供了第一个估计的教育差异，在特定年龄的患病率，随着时间的推移，在美国的教育水平的痴呆症患病率的变化。它还提供了有关预期寿命的信息，以及预期寿命的变化，痴呆症和认知健康的生活教育groups.Method：从2000年和2010年的健康和退休研究的认知数据被用来分类受访者为痴呆症，认知障碍无痴呆症（CIND），或认知完好。生命统计数据被用来估计教育组的生命表和沙利文方法被用来估计预期寿命的认知states.Results：更多的教育的人有较低的痴呆症的患病率，更多年的认知健康的生活，和更少的年与痴呆症。对于大多数性教育组来说，在良好认知方面花费的时间增加了，相反，在痴呆症方面花费的时间减少了。降低死亡率是提高认知健康寿命的最重要因素。受教育程度分布的变化在降低痴呆症患者的寿命方面发挥了重要作用。讨论：教育导致认知丧失的负担差异表明，社会地位低下对个人和社会都有重大影响。
Objectives: This article provides the first estimates of educational differences in age-specific prevalence, and changes in prevalence over time, of dementia by education levels in the United States. It also provides information on life expectancy, and changes in life expectancy, with dementia and cognitively healthy life for educational groups.Method: Data on cognition from the 2000 and 2010 Health and Retirement Study are used to classify respondents as having dementia, cognitive impairment without dementia (CIND), or being cognitively intact. Vital statistics data are used to estimate life tables for education groups and the Sullivan method is used to estimate life expectancy by cognitive state.Results: People with more education have lower prevalence of dementia, more years of cognitively healthy life, and fewer years with dementia. Years spent in good cognition increased for most sex-education groups and, conversely, years spent with dementia decreased for some. Mortality reduction was the most important factor in increasing cognitively healthy life. Change in the distribution of educational attainment has played a major role in the reduction of life with dementia in the overall population.Discussion: Differences in the burden of cognitive loss by education point to the significant cost of low social status both to individuals and to society.
