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 on…

Also they didn't randomize the activity level of the subjects by putting them on different exercise programs.

I would think that people being in an end of life state at the beginning of the study would tend to be more likely to be tired and avoid exercise.

It could well be that early undiagnosed terminal illness causes people to be sedentary and not the other way around.

> 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 ou…

Well these are the same types of people who told us coffee was bad, saturated fat was bad, low-fat/carbs-rich diets were good, etc. and have been found to be wrong across the board. I don't worry too much about how other busybodies tell me I should live my life.

Come on. This is HN. No one is telling anyone how to live their life. Well, people are but we all already know to ignore them right? We are trying to parse all this data about stand/sit/walk-desk and figure out if there is anything to it regarding overall mortality. If we can make some relatively small adjustments to our lives and gain back years that static positions may be taking from us why not? This is a quest for discovery about what the data is telling us. Yes, some of the time the data leads us on a path that is not the best (coffee/fats are bad?) -- it happens. Food and nutrition studies are worse than these types of studies, I think. There are so many more complicating factors compared to the broader strokes of these sort of lifestyle studies.

Earlier quoted context omitted.

I think its important to look at this studies from a birds eye view and not get too bogged down in the details. Is sitting for prolonged periods bad? Yes. Should you get up every 7.5 minutes to walk around? Probably over kill. If you're the type that goes into work, sits until lunch, then walks to the lunch table, then returns to your desk until closing time - you could probably benefit from more moving. My hope is t…

Other studies indicate standing all day isn't good either. You really need a combination of stand sit. I actually think ideal based on what I have read is going to end up being some sort of very slow walk. Static positions cause edema and clotting, period. The longer you hold a static position the worse it is. It can damage muscles due to reduced blood flow and the awkward stretching of muscles and connective tissue.…

I'm not much of a desk-stander my self, but it's nice to have the option. To clarify, I was advocating encouraging more options for desk workers - not strictly standing at work.

It would also be nice to have a longer standard lunch period. I would love to be able to work out and eat in the middle of my day, but 30 mins just isn't enough.

I baffled by how many tech guys/girls don't understand this. This is so obvious it hurts. At my company's last year medical checkup the results were just absurd, specially for men above 30 years old. Abdominal fat, high cholesterol, diabetes, etc..Yet, nobody gives a damn, almost no one changed their habits.

Guys, just get up and move. 30m-40m a day, you can fit this into your daily schedule, don't come up with excuses. If you can fit your TV shows/gaming or your accumulative time on social media, you can redirect that to your health instead. And the output will have a major impact not just to your health, but to your appearance and your confidence.

Eat healthy, exercise and go to bed on time. You don't have to go to a gym, you can buy some gear and follow a plan from your home. Trust me, the change can be quite dramatic.

Before work, or after work, pick a time, have a working out plan, track your progress, create the habit. After two months it will feel like not taking a shower if you skip it.

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 al…

Seconded. I used to feel lower back pain due to the amount of sitting at a desk. Running and lifting weights did wonders for how I feel on a daily basis.

Losing enough weight so that there's not cantilevered fat out front acting as a lever on your lower back muscles really helps.
