目标。在对临床人群的研究中，老年人的认知障碍与死亡率有关。本研究的目的是调查社区老年人群中与认知障碍相关的死亡风险。对1855名社区老年居民进行认知障碍及其他社会健康因素评估。定期对该样本进行复查，以评估健康和存活率的变化。在基线时，33%的样本为轻度受损，8%为重度受损。在48个月的观察期内，认知正常受试者的存活概率为0.85，轻度受损者为0.69，重度受试者为0.51。在对其他健康和社会协变量的影响进行调整后，严重受损的人死亡的可能性是未受损的人的两倍。那些轻度受损的人也有更高的风险。结论，其他研究人员发现，认知障碍是痴呆症的重要预测因素。我们发现，它也是死亡率的一个重要预测因素。及早发现认知受损并注意相关的健康问题，可能会改善这些老年人的生活质量，或许还会延长他们的寿命。
Objectives. Cognitive impairment among the elderly has been linked to mortality in studies of clinical populations. The purpose of this study was to examine the mortality risk associated with cognitive impairment among elderly populations in the community.Methods. Cognitive impairment and other social and health factors were assessed in 1855 elderly community residents. This sample was reinterviewed periodically to assess changes in health and survival.Results. At baseline 33% of the sample were mildly impaired and 8% were severely impaired. Across a 48-month observation period the survival probability was .85 for the cognitively unimpaired, .69 for the mildly impaired, and .51 for severely impaired respondents. When adjustments were made for the effects of other health and social covariates, severely impaired persons were twice as likely to die as unimpaired persons. Those who were mildly impaired were also at an increased risk.Conclusions, Other investigators have found that cognitive impairment is a significant predictor of dementia. We found that it is a significant predictor of mortality as well. Early detection of impaired cognition and attention to associated health problems could improve the quality of life of these older adults and perhaps extend their survival.
