Physical activity patterns and cognitive function in elderly women: a cross-sectional study from NHANES 2011-2014

Area of Science:

• Gerontology
• Neuroscience
• Public Health

Background:

• Global aging population presents challenges with cognitive decline, especially in women.
• Physical activity (PA) is a key non-pharmacological strategy for cognitive health in older adults.
• Understanding the impact of diverse PA patterns on cognitive function (CF) in elderly women is crucial.

Purpose of the Study:

• To investigate the association between PA, PA patterns (inactive, Weekend Warrior, Regular Exercise), and PA intensity with CF in elderly women.
• To analyze data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014.

Main Methods:

• Utilized NHANES 2011-2014 data.
• Employed multivariate regression analysis.
• Examined relationships between PA metrics and cognitive function.

Main Results:

• Significant positive correlation found between overall PA and CF in elderly women.
• Weekend Warrior (WW) and Regular Exercise (RE) patterns were linked to better CF than inactivity.
• Increasing PA intensity showed a progressive increase in CF.

Conclusions:

• Confirms a positive link between PA and CF in elderly women.
• Highlights that even intermittent, intensive PA (like WW) improves cognitive performance.
• Emphasizes the need for adaptable PA strategies to promote cognitive health in aging populations.
