Mixed

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.

While reducing sitting time is generally recommended, the specific impact on waist size may vary by race/ethnicity. For Non-Hispanic Whites, the link is clear. For others, the data is mixed or even shows a beneficial association in Blacks, suggesting biological or environmental differences. General advice to move more remains safe, but individual responses may vary.

Why this rating

Large sample size allows for subgroup analysis, but the interaction is complex and potentially confounded.
