Excessive sitting time is linked to cardiovascular disease morbidity.
To date, no studies have accurately measured sitting time patterns in people with
stroke. The purpose of this study was to investigate the amount and
pattern of accumulation of sitting time, physical activity, and use of time in
people with stroke compared with age-matched healthy peers. DESIGN: This study
used an observational design. METHODS: Sitting time (total and time accumulated
in prolonged, unbroken bouts of >/=30 minutes) was measured with an activity
monitor. Physical activity and daily energy expenditure were measured using an
accelerometer and a multisensory array armband, respectively. All monitors had a
7-day wear protocol. Participants recalled 1 day of activity (during monitor wear
time) using the Multimedia Activity Recall for Children and Adults. RESULTS:
Sixty-three adults (40 with stroke and 23 age-matched healthy controls)
participated. The participants (35% female, 65% male) had a mean age of 68.4
years (SD=10.0). Participants with stroke spent significantly more time sitting
(X=10.9 h/d, SD=2.0) compared with controls (X=8.2 h/d, SD=2.0), with much of
this sitting time prolonged (stroke group: X=7.4 h/d, SD=2.8; control group:
X=3.7 h/d, SD=1.7). Participants with stroke accumulated most of their sitting
time while watching television and in general quiet time, whereas control
participants spent more time reading and on the computer. Physical activity and
daily energy expenditure were lower in the stroke group compared with the control
group. LIMITATIONS: A sample of convenience was used to select participants for
the stroke and control groups, which may reduce the generalizability of results.
CONCLUSIONS: Participants with stroke spent more time sitting and less time in
activity than their age-matched peers. Further work is needed to determine
whether reducing sitting time is feasible and leads to clinically important
reductions in cardiovascular risk in this population.
