Sedentary Behavior and Mortality in U.S. Middle-Aged and Older Adults

This should be obvious, however people still refuse to get up, and just walk around every hour for a minute. I spend a silly amount of time behind a computer, but I'll do 10-20 pushups / jumping jacks, every hour or so. After hours, I'll bang out six miles on the hiking trails.

Get up, go get a drink, do a lap around the office. Get a stand/sit desk. Do some simple exercises. Pushups can be done anywhere, and will alleviate lower back pain.

> Evaluation of their joint association showed that participants classified as high for both sedentary characteristics (high sedentary time [≥12.5 h/d] and high bout duration [≥10 min/bout]) had the greatest risk for death.

Is sleep included in the 12.5 hours per day?

Even if it isn't, I and everyone I know sits for at least that long each day. Definitely for more than 10 minutes at a time. If we need to interrupt our sitting bouts every 7.5 minutes in order to be healthy, I don't know how the hell to do this.

Honestly, I feel like a study of this nature is backing up what we already know to a degree.

But, we need to know more and I feel like a 4 year tracking period isn't enough. For example, how do we know that people who were already the most unhealthy coming into this study are also the most sedentary? How are they handling these types of things.

The headline result (sedentary behavior leads to increased risk of mortality) is not completely supported by the results shown in the abstract.

They break the test subjects into four groups ranked by activity level, and compare the the highest activity group to the rest. But in the results, only the lowest activity group has a hazard ratio where the 95% confidence interval does not contain 1. Translation: the data only shows a meaningful difference in mortality risk between the highest and lowest activity groups. For the other two groups, the data does not support show an increased risk.
