Sitting too much may kill you in 14 ways

Sitting too much may kill you even if you exercise regularly, according to an American Cancer Society study.

If you sit for six hours a day or more, your risk of dying early jumps 19 percent, compared with people who sit fewer than three hours, the study, published in the American Journal of Epidemiology, suggests.

The study authors added, sitting may kill you in 14 ways, including: cancer; heart disease; stroke; diabetes; kidney disease; suicide; Parkinson’s disease; Alzheimer’s disease; nervous disorders; chronic obstructive pulmonary disease, or COPD; lung disease; liver disease; peptic ulcer and other digestive disease; and musculoskeletal disorders.

“The simple message is that we should be moving more,” said lead researcher Alpa Patel, strategic director of the cancer society’s prevention study-3.

“The less sitting you do, the better it is for you,” she said, “Breaking up an hour of sitting with 2 minutes of standing or light activity can improve cholesterol, blood sugar and blood pressure.”

The study however couldn’t prove cause and effect, but it’s clear that Americans are spending more time in their seats — watching TV, working and playing on computers and smartphones. With age people sit more, and people with chronic disease spend even more sedentary time, the researchers noted.

An Australian study estimated that 90 percent of non-working time was sedentary, and that more than half of it was spent watching TV or sitting at computers.

For the study, Patel’s team collected data on nearly 128,000 men and women who were part of an American Cancer Society prevention study. At the start of the study, all were free of major chronic diseases. During 21 years of follow-up, nearly 49,000 people died.

It’s not clear why prolonged sitting is unhealthy, Patel said. It’s possible that people who spend a lot of time on the couch also have other unhealthy behaviors, such as excess snacking, she suggested.

In addition, prolonged sitting has been linked to higher levels of triglycerides, blood sugar, blood pressure and insulin. Sitting has also been tied to inflammation caused by obesity.

These consequences might explain why sitting was linked with death from heart, liver and kidney disease, as well as cancer, diabetes and COPD, Patel said.

It’s less clear why death from suicide, Parkinson’s and Alzheimer’s, as well as nervous and musculoskeletal disorders, seems associated with sitting. For these, she said, it’s possible that the conditions themselves result in more sedentary time.

The increased mortality risk differed by disease, ranging from 10 percent for cancer to 60 percent for musculoskeletal disease, Patel said.

Dr. David Katz, director of the Yale-Griffin Prevention Research Center in Derby, Conn, said, “We have known for some time now that sitting for extended periods daily is injurious to health.”

He noted that this study links excessive sitting to an increased risk of dying early from an array of causes — everything from heart disease to suicide.

“Does this mean that sitting excessively increases suicide risk? That seems implausible,” Katz said. “Perhaps depressed people lack the motivation to get up and go out. But then again, we know that routine activity is important to mental health, so some contribution of sedentariness to the severity of depression is not out of the question.”

Even though more study is needed to figure out why sitting appears to boost the risk of early death, what to do about it is no mystery, he said.

Regular bedtime beneficial for heart and metabolic health among older adults

KATHMANDU — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But a new study on sleep patterns has suggested that a regular bedtime and wake time are just as important for heart and metabolic health among older adults too.

Researchers at Duke Health and the Duke Clinical Research Institute, in a study of 1,978 older adults, have found that people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.

The study  was published Sept 21 in the journal Scientific Reports.

“From our study, we can’t conclude that sleep irregularity results in health risks, or whether health conditions affect sleep,” said study’s lead author Jessica Lunsford-Avery.

“Perhaps all of these things are impacting each other.”

African-Americans had the most irregular sleep patterns compared to participants who were white, Chinese-American or Hispanic, the data showed.

Still, the data suggest tracking sleep regularity could help identify people at risk of disease, and where health disparities may impact specific groups.

Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.
