lower cognitive performance. This stresses the relevance to understand the prevalence and characteristics of PA and SB in the context of dementia. The aim of this study was to examine PA and SB characteristics of ambulatory and community dwelling patients with dementia compared to cognitively healthy age-, sexand weightmatched controls. Methods: A cross-sectional study design was used. Community dwelling patients with dementia were included (N1⁄445, age1⁄479.665.9 years, MMSE1⁄422.863.2). Controls were age-, sexand weight-matched to the dementia patients (N1⁄449, age1⁄480.067.7 years, MMSE1⁄429.061.2). Participants wore a wrist accelerometer for seven days. Data was conferred from counts per epoch to counts per minute (CPM). Cut-off points of 145 CPM, 145-274 CPM, 274-597 CPM and>597 CPMwere used for sitting, very light, light-to-moderate and moderate-to-vigorous PA, respectively. To account for individual differences in waking time, our primary analysis was based on activity levels expressed as a percentage of total (awake) measuring time.Results:Relative sitting time and the duration of average sitting bout was significantly higher in dementia patients compared to controls (median and interquartile range: 57% (49-68) vs 55% (47 – 59) and 18.3 (16.4–21.1) minutes vs 16.6 (15.3–18.4) minutes, P1⁄40.042 and 0.008 respectively). In addition, dementia patients spent a lower percentage of their waking time in light-to-moderate and moderate-to-vigorous intensity PA (20% (15–23) vs 22% (18–25) and 5% (2–10) vs 10% (5–13), P1⁄40.017 and 0.001 respectively). Whilst older controls show significantly less PA and more SB compared to their younger peers, no such changes were present when comparing dementia patients aged 80 years and aged<80 years. Conclusions:In the current study we revealed that dementia patients are more sedentary and perform less PA compared to cognitively healthy controls, as measured by accelerometry. This may have clinically important consequences, given the observation of previous prospective studies that this type of behavior independently predicts all-cause mortality and morbidity.
