Adherence
Higher daily total sitting time is associated with a greater risk of all-cause mortality, with the risk increasing non-linearly (specifically 5% per hour) for individuals sitting more than 7 hours per day, even after adjusting for moderate-to-vigorous physical activity.
If you sit for more than 7 hours a day, your risk of death increases by about 5% for every additional hour, even if you exercise. To mitigate this, try to break up long periods of sitting, especially if your total sitting time exceeds 7 hours.
GoodSupportsHIGH confidence
Higher amounts of daily total sitting time are associated with greater risk of all-cause mortality... For every 1-hour increment of sitting in intervals 0-3, >3-7 and >7 h/day total sitting time, the HRs were 1.00 (95% CI: 0.98-1.03), 1.02 (95% CI: 0.99-1.05) and 1.05 (95% CI: 1.02-1.08) respectively.
Why this rating
Meta-analysis of 6 prospective cohort studies with large sample size (n=595,086), though heterogeneity was high (I2=82.7%) and measurement relied mostly on self-report.
