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.

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.
