Device-measured PA modes (duration and intensity) and its association with incident dementia (all-cause, Alzheimer’s disease, and vascular dementia). All analyses were performed excluding participants with all-cause dementia and neurological disorders at baseline. Analyses were adjusted by age, sex, deprivation, ethnicity, education, morbidity count, BMI, smoking, alcohol intake, fruit and vegetable, total fish, red meat, and processed meat intake, log reaction time and log visual memory. The minimum value of each exposure was used as a reference group: 5531.904 MET/min/week for total PA, 4424.112 MET/min/week for light PA, 645.12 MET/min/week for moderate PA, 0 MET/min/week for vigorous PA and 645.12 MET/min/week for MVPA. AD, Alzheimer’s disease; MET, metabolic equivalent tasks; PA, physical activity; MVPA, moderate-to-vigorous physical activity
