背景：粮食不安全仍然是一个全球性的公共卫生问题。经历粮食不安全与老年人认知功能较差有关。然而，很少有研究探讨了墨西哥老年人一生中经历的粮食不安全与认知功能的关系。数据来自2015年墨西哥健康与老龄化研究（n = 11，507名50岁及以上的成年人）。早期和晚期的粮食不安全是通过自我报告确定的。我们评估了这两种食物不安全指标与多项认知任务（言语学习、言语回忆、视觉扫描和言语流畅性）的表现之间的关系，同时使用线性回归控制了关键的健康和社会人口混杂因素。结果如下：在描述性分析中，与粮食安全相比，在早期或晚期经历过粮食不安全的受访者在所有认知任务中的表现都显着更差。在调整了健康和社会人口混杂因素的模型中，早期的食物不安全预测了更差的言语学习表现，而晚期的食物不安全与更差的视觉扫描表现相关。结论：食物不安全与墨西哥全国代表性老年人样本中认知功能较差有关。然而，研究结果表明，影响的意义取决于认知任务，当在生命过程中的粮食不安全的经验。
Background: Food insecurity remains a global public health problem. Experiencing food insecurity is related to poorer cognitive function among older adults. However, few studies have examined how food insecurity, experienced over the life-course, relates to cognitive function among older adults in Mexico. Methods: Data came from the 2015 Mexican Health and Aging Study (n = 11,507 adults aged 50 and over). Early- and late-life food insecurity were ascertained by self-report. We evaluated how both measures of food insecurity related to the performance of multiple cognitive tasks (Verbal Learning, Verbal Recall, Visual Scanning, and Verbal Fluency), while controlling for key health and sociodemographic confounders using linear regression. Results: In descriptive analyses, respondents who experienced food insecurity in either early or late life performed significantly worse on all cognitive tasks when compared to the food secure. In models adjusted for health and sociodemographic confounders, early-life food insecurity predicted worse Verbal Learning performance and late-life food insecurity was associated with poorer Visual Scanning performance. Conclusions: Food insecurity was related to poorer cognitive function in a nationally representative sample of older adults in Mexico. However, results suggested that the significance of effects depended on cognitive task and when in the life-course food insecurity was experienced.
