Abbreviations: SCD, subjective cognitive decline; OR, odds ratio; AOR, adjusted odds ratio; CI, confidence interval; yrs, years.
All estimates are weighted.
Logistic regression models adjusted for sex, age group (45–54, 55–64, 65–74, and ≥75 years), race/ethnicity, education level, and body mass index.
Physical activity level definitions: active (meeting the aerobic physical activity guideline of 150 minutes/week of moderate-intensity physical activity, 75 minutes/week of vigorous-intensity physical activity, or an equivalent combination); insufficiently active (some activity, but not enough to meet active definition); and inactive (no leisure-time physical activity for at least 10 minutes).
Significant linear trend (P<0.05).
