Mixed

Prolonged sitting in specific contexts (TV-viewing or occupational sitting) does not show a significant association with all-cause or cardiometabolic mortality in the short term (3.3 years), unlike total sitting time.

Don't panic about watching TV or sitting at work specifically. Focus on reducing your total hours of sitting throughout the entire day.

TV-viewing time and occupational sitting showed no or borderline significant associations with all-cause or cardiometabolic disease-related mortality over the same follow-up period.

Why this rating

Same high-quality cohort data as N1, but the null finding for specific contexts is robust within the study's timeframe.
