BACKGROUND Work has been associated with cognitive health. We examined whether retirement from work is associated with a decrease in episodic memory and whether this effect differs when considering workers' occupational class. METHODS In this prospective study using the English Longitudinal Study of Ageing (ELSA), we examined 1629 persons aged 50-75 years who were in paid work at baseline. A two-slope random effects linear regression centred at retirement was used to study the effect of retirement on episodic memory. The potential effect modification by occupational class was examined. RESULTS While memory trajectories show slightly decreasing memory scores before and afterretirement, the decreasing rates for both periods were similar [episodic memory β2b-β2a= -0.03, 95% confidence interval (CI) -0.08, 0.02]. When stratifying by occupational class, there was also no substantial difference in episodic memory trajectories before and after retirement. However, the lower occupational class showed a clear decline in episodic memory with time (pre-retirement β2a = -0.11, 95% CI -0.19, -0.03; post-retirement β2b = -0.13, 95% CI -0.19, -0.07) which was not evident for the higher occupational classes. CONCLUSIONS Our results show no observable difference in trajectories of change in episodic memory before and after retirement. However, the steeper memory decline in workers belonging to the lower occupational class may limit their prospect of prolonging their working lives. Hence enrichment programmes for the prevention of memory decline for these workers should be considered.

情景记忆的退休和衰退:对英国成年人的一项前瞻性研究分析。

背景技术工作已经与认知健康相关联。我们检查了从工作中退休是否与情景记忆的减少有关,以及在考虑工人的职业类别时这种影响是否不同。方法在本前瞻性研究中,我们使用了英国老龄化纵向研究(ELSA),检查了1629名年龄在50-75岁之间的有薪基线工作的人。以退休为中心的两斜率随机效应线性回归用于研究退休对情节记忆的影响。研究了按职业分类的潜在效果修改。结果虽然记忆轨迹显示退休前后的记忆分数略有下降,但两个时期的下降率相似[周期性记忆β2b-β2a= -0.03,95%置信区间(CI)-0.08,0.02]。按职业分类时,退休前后的情节记忆轨迹也没有实质性差异。但是,较低的职业类别显示随时间变化的情节记忆明显减少(退休前β2a= -0.11,95%CI -0.19,-0.03;退休后β2b= -0.13,95%CI -0.19,-0.07)这对于高等职业阶层而言并不明显。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业类别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。退休前后的情节记忆轨迹也没有实质性差异。但是,较低的职业类别显示随时间变化的情节记忆明显减少(退休前β2a= -0.11,95%CI -0.19,-0.03;退休后β2b= -0.13,95%CI -0.19,-0.07)这对于高等职业阶层而言并不明显。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业类别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。退休前后的情节记忆轨迹也没有实质性差异。但是,较低的职业类别显示随时间的情景记忆明显下降(退休前β2a= -0.11,95%CI -0.19,-0.03;退休后β2b= -0.13,95%CI -0.19,-0.07)这对于高等职业阶层而言并不明显。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业级别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。较低的职业阶层显示随时间的情景记忆明显下降(退休前β2a= -0.11,95%CI -0.19,-0.03;退休后β2b= -0.13,95%CI -0.19,-0.07)对于较高的职业阶层而言,这一点并不明显。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业类别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。较低的职业阶层显示随时间的情景记忆明显下降(退休前β2a= -0.11,95%CI -0.19,-0.03;退休后β2b= -0.13,95%CI -0.19,-0.07)对于较高的职业阶层而言,这一点并不明显。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业类别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业级别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。结论我们的研究结果表明,退休前后情节性记忆变化的轨迹没有明显差异。但是,属于较低职业类别的工人的记忆力下降可能会限制他们延长工作寿命的前景。因此,应考虑为防止这些工人的记忆力减退而开展的丰富计划。
