The Claim
Adults who report sitting for more than 8 hours per day demonstrate a 46% increased relative risk of all-cause mortality and a 79% increased relative risk of cardiovascular disease mortality compared to adults who report sitting for less than 4 hours per day, after statistical adjustment for physical activity levels and additional confounding variables.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you sit for more than 8 hours a day, you have a much higher chance of dying early—especially from heart problems—compared to people who sit less than 4 hours, even when accounting for how much they exercise.

Adults who sit more than 8 hours per day have a 46% higher risk of all-cause mortality and a 79% higher risk of cardiovascular disease mortality compared to adults who sit less than 4 hours per day, after adjusting for physical activity and other confounders
What the research says
1 studyThis study looked at how long people sit each day and whether it affects how long they live. It found that people who sit more than 8 hours a day have a 46% higher chance of dying from any cause and a 79% higher chance of dying from heart disease compared to people who sit less than 4 hours a day - exactly matching what the claim says.
