BACKGROUND Chile has one of the highest life expectancies within Latin American. This is the first study to determine health expectancies in older populations in Chile, considering cognitive status as a health indicator. METHODS We estimated prevalence of cognitive decline among people aged 60 years and over based on the Mini-mental State Examination and the Pfeffer Functional Activities Questionnaire, with data from the National Survey of Health (2003, 2009, 2016). Life expectancy free of cognitive impairment was calculated using the Sullivan method. RESULTS At age 60, life expectancy free of cognitive impairment was more than 3 years longer for women, compared to men of the same age. Life expectancy free from cognitive impairment was higher for both men and women aged 60 in 2016 when compared to 2003 (2.1 and 2 years higher, respectively). CONCLUSIONS Longer life expectancy in women was accompanied by more years free of cognitive impairment. Men expected to live a similar proportion of years free of cognitive impairment, compared to women. Common and standardised assessments of health status of older people should be adopted in Latin American studies, to allow for time-trend analyses and international comparisons.

智利老年人在有无认知障碍的情况下的预期寿命：《国家健康调查》（2003年，2009年和2016年）的结果。

背景技术智利具有拉丁美洲最高的预期寿命之一。这项研究以认知状况为健康指标，是第一个确定智利老年人口健康预期的研究。方法我们根据《国家心理健康调查》（2003年，2009年，2016年）的数据，通过“迷你精神状态检查”和“ Pfeffer功能活动调查表”估算了60岁及60岁以上人群的认知能力下降的患病率。使用Sullivan方法计算了无认知障碍的预期寿命。结果在60岁时，与同年龄的男性相比，女性的无认知障碍的预期寿命要长3年以上。与2003年相比，2016年60岁的男性和女性在没有认知障碍的情况下的预期寿命都更高（分别为2.1岁和2岁）。结论妇女的预期寿命更长，并伴有更多的无认知障碍的年限。与女性相比，男性预期可以无认知障碍地生活相似的比例。拉丁美洲的研究应采用对老年人健康状况的通用和标准化评估，以便进行时间趋势分析和国际比较。
