<p>1 revision imported</p> <p><b>New page</b></p><div>https://pubmed.ncbi.nlm.nih.gov/22450936/ (222k australians)&lt;br/&gt;<br /> Sitting less than 8 hours per day has almost no effect on lifespan. Sitting 8-11 hours per day gives RR ~1.1, more than 11h/day =&gt; RR ~1.4&lt;br/&gt;<br /> Table 2: with increasing physical activity, the harm from 8-11h/day decreases. Though harm remains in &gt;300min/weak physical activity group (300min is really not much though).<br /> &lt;br/&gt;&lt;br/&gt;<br /> <br /> https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0037696 &lt;br/&gt;<br /> Sitting much is harmful even if there is enough moderate2vigorous activity&lt;br/&gt;<br /> Table 2: - even adjusted for moderate2vigorous (model 3), 3rd quartile of sedentary time (&gt;9.2h) greatly increases all-cause mortality, RR 2.74 (1.35 - 5.52). &lt;br/&gt;<br /> 2nd quartile (&gt;7.6h) also increases all-cause mortality (even if not very statistically significant). &lt;br/&gt;<br /> Used accelerometer. Sedentary means &lt;100 counts of accelerometer per minute.&lt;br/&gt;<br /> <br /> Btw, 2k counts/min is MET 3; 6k - is MET 6 &lt;br/&gt;<br /> https://pubmed.ncbi.nlm.nih.gov/18091006/ , pp.2-3</div>
