Figure 1.

Continuous dose-response associations of accelerometer-measures of MVPA, steps/day, LPA, sitting time, and mean sitting bout duration with incident MCI, probable dementia, and combined MCI or probable dementia.

Abbreviations: HR=hazard ratio; LPA=light intensity physical activity; MVPA=moderate-to-vigorous intensity physical activity; MSBD=mean sitting bout duration. MCI=mild cognitive impairment; BMI=body mass index

Models adjusted for age, race and ethnicity, education, alcohol consumption, smoking status, diabetes, hypertension, RAND-36 physical functioning, BMI, and APOE ε4 carrier status. Results were trimmed at the 1st and 99th percentiles. The reference was set to the 10th percentile
