Residential differences in 24-hour movement behavior are driven by sedentary behavior and physical activity—not sleep.

INTRODUCTION
Most people with dementia transition to nursing home care. Residential environment may influence how they spend their day. A 24-hour day consists of sleep, sedentary behavior, and physical activity.
Aim: To examine residential-related differences in 24-hour movement behavior in people with dementia.

METHODS
Cross-sectional study
People with dementia: MMSE < 21
Community-dwelling: on nursing home waiting list
Nursing home-dwelling: ≤ 6 weeks after admission
Movement behaviors measured with triaxial accelerometers
Compositional Data Analysis (isometric log-ratio transformations) MANOVA was performed on two behavioral balances:
ILR₁: SLEEP BALANCE (Sleep vs. Sedentary behavior + Physical activity), ILR₂: ACTIVITY BALANCE (Sedentary behavior vs. Physical activity).

RESULTS
SAMPLE CHARACTERISTICS
setting, n, Age (years), Female (%), MMSE (0-30), Walking aid (%)
Community, 30, 85, 53, 18, 47
Nursing home, 32, 84, 81, 16, 78
OVERALL COMPOSITION
Sleep 54.3%
Sedentary behavior 32.6%
Physical activity 13.2%
TERNARY PLOT
MAIN FINDINGS
Composition differed between residential settings.
Difference driven by the balance between sedentary behavior and physical activity (ilr2).
No difference in sleep balance (ilr1).

CONCLUSIONS
➢ 24-hour movement behavior composition differs between community- and nursing home-dwelling people with dementia.
➢ Nursing home residents are more sedentary and less physically active.
➢ Provides direction for future longitudinal studies investigating the mechanisms underlying these differences.
