Low Physical ACTIVITY IS ASSOCIATED WITH HIGH blood PRESSURE AND HIGH PLASMA GLUCOSE IN Stroke SURVIVORS AT 12 MONTHS FOLLOWING REHABILITATION

Abstract

Background/AimsStroke survivors are at a high risk of having a second stroke and are known to participate in low levels of physical activity (PA). The objective of this longitudinal study was to measure PA over 12 months in stroke survivors who had completed rehabilitation and investigate relationships between PA and cardiovascular risk factors.MethodsSurvivors of first ever stroke admitted to a large metropolitan rehabilitation hospital were recruited.The primary outcome was duration of moderate-vigorous PA (MVPA) (minutes/day) measured by the Sensewear Armband. Secondary outcomes included other PA measures (steps/day, sedentary and light PA time bouts of MVPA) and cardiovascular risk factors (blood pressure, fasting lipid profile and plasma glucose).ResultsParticipants (n=61) had mean age 64 [SD 14], median gait speed 1.3m/s (IQR 0.9,1.5) and 22 were female (36%). On average MVPA was high (median 73 minutes/day, IQR 24,131), but steps/day was low (median 3780, IQR 765,6703). At 12 months following rehabilitation completion there was a weak relationship between lower MVPA and higher systolic blood pressure (rS=-0.2449, p=0.06). Shorter MVPA bout duration was associated with higher plasma glucose levels (rS=-0.2645, p=0.04). No other PA variable was associated with cardiovascular risk markers.ConclusionsAt 12 months post completion of rehabilitation stroke survivors who completed less MVPA tended to have higher systolic blood pressure and plasma glucose and are therefore at a higher risk of future stroke and cardiovascular disease. Promoting strategies to incorporate MVPA into stroke survivors' lives should be a focus for health professionals.
