Abstract

Objective: Cognitive decline in older adults is a public health issue, with modifiable factors like obesity and sleep potentially influencing this trajectory. Previous research on their relationship with executive function has shown mixed results, particularly across older adulthood.

Methods: This study utilized time-varying effect modeling (TVEM) to assess the impact of body mass index (BMI) and sleep on executive function in older adults aged 60 to 79, using data from the National Health and Nutrition Examination Survey (NHANES) 2011-2012 and 2013-2014 cycles (N = 2543). Executive function was evaluated using the Digit Symbol Substitution Test (DSST).

Results: Findings indicated that while BMI did not significantly affect cognition, adequate sleep (7-8 hours) was linked to better executive function, especially in individuals aged 63 to 65.

Conclusion: These results highlight sleep's importance for cognitive health and suggest interventions focusing on sleep and weight management to mitigate age-related cognitive decline.

成年后期健康行为与执行功能：一个时变效应模型分析。

目的：老年人的认知能力下降是一个公共卫生问题，肥胖和睡眠等可改变因素可能会影响这一轨迹。之前关于它们与执行功能之间关系的研究显示了不同的结果，尤其是在老年人中。方法：本研究采用时变效应模型（TVEM）评估体重指数（BMI）和睡眠对60 ~ 79岁老年人执行功能的影响，数据来自2011-2012年和2013-2014年国家健康与营养检查调查（NHANES）周期（N = 2543）。使用数字符号替代测试（DSST）评估执行功能。结果：研究结果表明，虽然BMI对认知能力没有显著影响，但充足的睡眠（7-8小时）与更好的执行功能有关，尤其是在63至65岁的人群中。结论：这些结果强调了睡眠对认知健康的重要性，并建议通过干预睡眠和体重管理来减轻与年龄相关的认知能力下降。

期刊介绍： The Journal of Aging and Health is an interdisciplinary forum for the presentation of research findings and scholarly exchange in the area of aging and health. Manuscripts are sought that deal with social and behavioral factors related to health and aging. Disciplines represented include the behavioral and social sciences, public health, epidemiology, demography, health services research, nursing, social work, medicine, and related disciplines. Although preference is given to manuscripts presenting the findings of original research, review and methodological pieces will also be considered.
