Adherence
Breaking up sedentary time with interruptions (breaks) is beneficially associated with lower waist circumference and lower C-reactive protein, independent of total sedentary time.
Don't just count total sitting hours; focus on breaking them up. Stand up or move for a minute every 30-60 minutes. This 'breaking up' of sitting time is linked to a smaller waist circumference and lower inflammation, regardless of how many total hours you sit.
GoodSupportsHIGH confidence
Independent of potential confounders and sedentary time, breaks were beneficially associated with waist circumference and C-reactive protein (P for trends <0.05).
Why this rating
Same high-quality observational data as N1, but focused on the 'breaks' metric.

More from this paper
- Prolonged sedentary time is detrimentally associated with adverse cardio-metabolic and inflammatory biomarkers (waist circumference, HDL-cholesterol, C-reactive protein, triglycerides, insulin, HOMA-%B, and HOMA-%S) independent of moderate-to-vigorous physical activity levels.Good
- The association between sedentary time and waist circumference varies by race/ethnicity, being detrimental in Non-Hispanic Whites, null in Mexican Americans, and beneficial in Non-Hispanic Blacks.Good
