Adherence
Higher daily sitting time is associated with a dose-response increase in all-cause and cardiovascular disease mortality, independent of leisure-time physical activity levels.
Track your daily sitting time, not just your exercise minutes. If you sit for most of the day, your risk of early death from heart disease or other causes increases, even if you exercise regularly. Try to stand up and move briefly every hour to mitigate this risk.
GoodSupportsHIGH confidence
These data demonstrate a dose–response association between sitting time and mortality from all causes and CVD, independent of leisure time physical activity.
Why this rating
Large prospective cohort (n=17,013), long follow-up (12 years), multivariate adjustment, but relies on self-reported sitting time.
