Patterns of sedentary behavior by cognition groups.

	Normal (n = 271)	Low MoCA only (n = 252)	MCI (n = 105)	AD (n = 182)
Average sedentary bout length	6.6 ± 0.2^d	6.5 ± 0.2^d	6.3 ± 0.3^d	7.9 ± 0.2^abc
Numbers of sedentary bouts (≥ 1 min)	91.5 ± 1.0^d	91.4 ± 1.0^d	89.4 ± 1.6	86.1 ± 1.3^ab
Numbers of sedentary bouts (≥ 30 min)	3.3 ± 0.1^d	3.3 ± 0.1^d	3.5 ± 0.2^d	4.1 ± 0.1^abc
Numbers of non-sedentary bouts (1–3 min)	60.9 ± 0.8	60.5 ± 0.8	58.1 ±1.3	59.3 ± 1.1
Numbers of non-sedentary bouts (≥ 10 min)	10.0 ± 0.3^d	10.2 ± 0.3^d	10.6 ± 0.4^d	8.5 ± 0.3^abc

Notes: MoCA = Montreal Cognitive Assessment; MCI = mild cognitive impairment; AD = Alzheimer’s disease.

Least square means are adjusted for age, gender, years of education, BMI, usual gait speed, living status, disease burden and wear time.

^a:

p < 0.05 for pairwise mean difference when comparing with normal group.

^b:

p < 0.05 for pairwise mean difference when comparing with low MoCA only group.

^c:

p < 0.05 for pairwise mean difference when comparing with MCI group.

^d:

p < 0.05 for pairwise mean difference when comparing with AD group.
