Cross-sectional association between physical activity level and subjective cognitive decline among US adults aged ≥45 years, 2015.

摘要: Abstract Subjective cognitive decline (SCD) is the self-reported experience of worsening or more frequent confusion memory loss within previous 12 months and can be one earliest symptoms Alzheimer's disease. Regular physical activity contribute to primary, secondary, tertiary prevention decline. At national level, prevalence estimates SCD by level in United States are currently unknown. The purpose this study examine resulting functional limitations among US adults aged ≥45 years. Data from 33 states District Columbia participating 2015 Behavioral Risk Factor Surveillance System (N = 128,925) were analyzed. We estimated (a positive response a question about 12 months) overall based on current guidelines (i.e., active, insufficiently inactive). Odds ratios using logistic regression models adjusting for respondent characteristics. Overall, 11.3% ≥45 years reported SCD. Prevalence increased as decreased (active: 8.8%; active: 11.4%; inactive: 15.7%). Among those with SCD, also 40.5%; 50.0%; 57.4%). These differences largely remained after Findings highlight potential public health impact nationally efforts promote health.
