The Claim
There is a modest phenotypic correlation (r = 0.33) between objectively measured sedentary time and self-reported sitting, with 45% of this association attributable to shared genetic influences and a genetic correlation of 0.49, indicating partial overlap in the genetic architecture underlying both measures.
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.
How much you say you sit and how much you actually sit are somewhat linked — about 1 in 3 people who report sitting a lot really do. And nearly half of that link comes from shared genes, meaning your DNA plays a role in both what you do and what you say about it.
See the scientific wording
There is a modest phenotypic correlation (r = 0.33) between objectively measured sedentary time and self-reported sitting, with 45% of this association explained by shared genetic influences and a genetic correlation of 0.49, indicating partial overlap in the genetic basis of both measures.
What the research says
1 studyStudy: Heritability of objectively assessed and self‐reported sedentary behavior
The study looked at how much people sit and whether what they report matches actual sitting time. It found that genetics partly explain both, and the numbers in the claim match exactly what the study found.
