Summary Sedentary behaviour is associated with lower cognitive performance , although the attributable risk of sedentary time to all-cause dementia incidence is unclear .
Our systematic review provides evidence that limiting sedentary time and concomitantly engaging in regular moderate-to-vigorous physical activity may best promote healthy cognitive ageing
Aim The increasing rate of all-cause dementia worldwide and the lack of effective pharmaceutical treatments emphasise the value of lifestyle approaches as prevention strategies .
Emerging evidence suggests sedentary behaviour is associated with impaired cognitive function .
A better underst and ing of this association would significantly add to our knowledge of how to best promote healthy cognitive ageing .
Thus , we conducted a systematic review ascertaining the contribution of sedentary behaviour towards associated changes in cognitive function over the adult lifespan .
Too much sitting: the population health science of sedentary behavior.
Even when adults meet physical activity guidelines , sitting for prolonged periods can compromise metabolic health .  Television ( TV ) time and objective measurement studies show deleterious associations , and breaking up sedentary time is beneficial .  Sitting time , TV time , and time sitting in automobiles increase premature mortality risk . Further evidence from prospect i ve studies , intervention trials , and population -based behavioral studies is required
