Introduction: 

Inequalities in life expectancy and mortality by social deprivation in the general population of the United Kingdom are widening. For people with dementia, data on potential gradients in life expectancy and mortality by social deprivation are sparse. This study aimed to explore potential differentials in life expectancy and mortality in people with dementia according to social deprivation.

Methods: 

Using The Health Improvement Network (THIN) primary care database, we included people with a diagnosis of dementia in the United Kingdom in 2000 to 2016 and obtained data on age at death and mortality. Comparisons were made according to social deprivation quintiles adjusting for age at diagnosis.

Results: 

Among 166,268 people with dementia there were no differences in life expectancy and mortality in the most deprived compared with the least deprived. This pattern has been stable during the study period, as no increasing inequalities in life expectancy and mortality according to social deprivation were found.

Discussion: 

Contrary to the general population, there were limited inequalities in life expectancy and mortality according to social deprivation for people with dementia.

英国痴呆症患者的预期寿命和死亡率中的社会不平等现象。

介绍： 

联合王国总人口中由于社会剥夺而导致的预期寿命和死亡率不平等现象正在扩大。对于痴呆症患者，关于按社会剥夺的预期寿命和死亡率的潜在梯度的数据很少。这项研究的目的是根据社会剥夺来探索痴呆患者的预期寿命和死亡率的潜在差异。

方法： 

使用健康改善网络（薄）初级保健数据库，我们附带的诊断人的老年痴呆症在英国在2000年死亡，死亡率到2016年和获得的数据年龄。根据诊断时调整年龄的社会贫困五分位数进行比较。

结果： 

在166,268名痴呆症患者中，最贫穷的人群与最贫穷的人群相比，预期寿命和死亡率没有差异。在研究期间，这种模式一直稳定，因为没有发现由于社会剥夺而导致的预期寿命和死亡率不平等加剧。

讨论： 

与普通人群相反，根据痴呆症患者的社会剥夺，其预期寿命和死亡率方面的不平等程度有限。
