“…Prior research examined the effects of physical activity on cognitive functioning using cognitive assessments [1,4,6,9,11], whereas this study defined cognitive decline as self-reported "difficulty concentrating, remembering, or making decisions. "…”

“…In addition, this study examined females ages 55 to 64, whereas most previous research focused on the elderly [1,[6][7][8]12]. The variables in this study were concurrent levels of cognitive decline and physical activity levels at one point in time; therefore, benefits of physical activity for cognitive decline may not be immediate.…”

“…In addition, stress can counteract neuroprctive influences, leading greater risk for cognitive decline [1,4], and excess sleep could be a symptom of certain disorders, such as depression, that are associated with increased cognitive decline [6].…”

“…Indeed, lower levels of depressive symptoms are associated with greater neuroprotective effects [1], and the absence of diabetes, stroke, or heart attack tend to be associated with greater mental functioning in older adults [6].Aside from age, inactivity is identified as the predominant risk factor for many disease processes [1], which include physical, as well as cognitive and neurologic decline. Deficits in cognitive and neurologic function could potentially be prevented or slowed with health promotion and physical activity [4].…”

Purpose: Physical activity could help prevent or slow deficits in cognition as an individual age; however, little is known about this relationship in females ages 55 to 64. The purpose of this study was to assess the relationship between physical activity levels and cognitive decline in females ages 55 to 64. Methods:This cross sectional analysis used 2015 data from the Behavioral Risk Factor Surveillance System (BRFSS) for females ages 55 to 64 in Connecticut, Montana, and Oregon. Logistic regression was used to assess the relationship between physical activity levels and cognitive decline while controlling for health and demographic factors.Results: Across states, few participants reported cognitive decline (10-14%), and only one-fifth reported being inactive (18-29%), while twice as many reported being highly active (34-48%). Adjusted results indicated that cognitive decline was not found to be significantly related to physical activity levels in any state, but cognitive decline was significantly related to number of health conditions, mental health, and substance use (all with moderate to large effect sizes) in two or three of three states. Conclusion:Across states, cognitive decline was not related to physical activity levels in females ages 55 to 64. The measurement for cognitive decline provided a limited scope of the condition and this study was unable to control for menopause and hormone replacement therapy, which may affect the outcome.Primary providers should not screen for physical activity levels related to cognitive decline in this population, but should screen for cognitive decline, multiple health conditions, current mental health issues, and substance use, if symptoms present for any of these in this target population.Providers should educate patients about the overall benefits of physical activity, but should focus on concurrently managing health conditions and discontinuing tobacco use as related to cognitive decline in females ages 55 to 64.

ImportancePhysical activity is associated with the risk for cognitive decline, but much of the evidence in this domain comes from studies with short follow-ups, which is prone to reverse causation bias.ObjectiveTo examine how length of follow-up, baseline age, physical activity amount, and study quality modify the longitudinal associations of physical activity with cognition.Data SourcesObservational studies of adults with a prospective follow-up of at least 1 year, a valid baseline cognitive measure or midlife cohort, and an estimate of the association of baseline physical activity and follow-up cognition were sought from PsycInfo, Scopus, CINAHL, Web of Science, SPORTDiscus, and PubMed, with the final search conducted on November 2, 2022.Study SelectionTwo independent researchers screened titles with abstracts and full-text reports.Data Extraction and SynthesisTwo reviewers independently assessed study quality and extracted data. Pooled estimates of association were calculated with random-effects meta-analyses. An extensive set of moderators, funnel plots, and scatter plots of physical activity amount were examined. This study is reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.Main Outcomes and MeasuresPooled estimates of the associations between physical activity and global cognition, as well as specific cognitive domains, were examined.ResultsA total of 104 studies with 341 471 participants were assessed. Analysis of binary outcomes included 45 studies with 102 452 individuals, analysis of follow-up global cognition included 14 studies with 41 045 individuals, and analysis of change in global cognition included 25 studies with 67 463 individuals. Physical activity was associated with a decreased incidence of cognitive impairment or decline after correction for funnel plot asymmetry (pooled risk ratio, 0.97; 95% CI, 0.97-0.99), but there was no significant association in follow-ups longer than 10 years. Physical activity was associated with follow-up global cognition (standardized regression coefficient, 0.03; 95% CI, 0.02-0.03) and change in global cognition (standardized regression coefficient, 0.01; 95% CI, 0.01 to 0.02) from trim-and-fill analyses, with no clear dose-response or moderation by follow-up length, baseline age, study quality or adjustment for baseline cognition. The specific cognitive domains associated with physical activity were episodic memory (standardized regression coefficient, 0.03; 95% CI, 0.02-0.04) and verbal fluency (standardized regression coefficient, 0.05; 95% CI, 0.03-0.08).Conclusions and RelevanceIn this meta-analysis of the association of physical activity with cognitive decline, physical activity was associated with better late-life cognition, but the association was weak. However, even a weak association is important from a population health perspective.
