Heart Study shows why some types of sitting can pose greater health risks



A society, we sit too much. We're in the car, we're sitting at our desks, and we drop on the couch when we get home. But not all seats are the same. Each of these approaches to sitting poses a very different risk to heart health, according to a study published on Wednesday in the Journal of American Heart Association .

… maybe we should focus on interventions that break up or break down Reduce television at home.

Although sitting at the desk may be the worst, the study shows that for at least one American population, occupational sitting is not the highest burden on heart health. Instead, the usual evening sitting ritual is to have a meal in front of the TV and watch the show hour after hour, which has been selected to fill the void left by Game of Thrones .

  sitting on the couch
Sitting in the free time (especially in front of the TV) was associated with the risk of heart problems, whereas sitting for professional reasons had no significant connection.

Analysis of the data of 3,592 African Americans enrolled in the Jackson Heart Study found that people who sat in front of the TV for four hours or more each night [49] were 49 percent more likely one had a heart attack than those who watched TV less than two hours a day.

In comparison, people with the highest occupational seat count showed no significant change in their cardiovascular disease risk compared to rare people. Study author Jeanette Garcia, Ph.D., a sports physiologist at the university of Central Florida, said to Inverse :

"Although I do not suggest that there are absolutely no health risks The results of our study suggest that perhaps we should focus on interventions that television at home interrupt or restrict, "says Garcia Inverse.

Sitting a t Working or Sitting at Home

The Jackson Heart Study tracked participants on average for almost eight and a half years. During this time, 129 heart attacks and 205 deaths occurred (these were summarized in this analysis). Garcia noticed a pattern of heightened risk in the data on these deaths. She believes that it is probably related to other aspects of sedentary life that are associated with long hours watching TV.

The big difference between sitting at home and sitting at work is that you tend to work without interruption. In an office, sitting at a desk can be interrupted by everyday activities such as a printer, a coffee break or the visit of colleagues. Meanwhile, sitting in front of the TV is a continuous sitting time. Garcia points out that there may be additional risks resulting from a full uninterrupted time during a TV binge.

"This type of activity can interrupt long periods of sitting, which is better than a longer, uninterrupted sitting time, which is more common in television, especially at night when you are tired," she says. "Even if you sit at your desk, you can fidget or stretch what does not look like a lot of movement, but every bit can help."

How society promotes certain types of sitting

The inertia associated with it During the sitting period, Garcia's findings also revealed a variety of other health behaviors.

For example, people who spent more time watching television were more likely to be less active in their spare time and more likely to smoke, drink and eat unhealthily. Those with the highest employment had the demographic characteristics of high-income employees at the reception. They were younger, more likely to eat healthier and more recreational.

  Sitting, watching TV,
Television is usually an uninterrupted sitting time, while sitting at work is often interrupted with short breaks.

In addition, people who sat most for work were, above all, wealthier than those who sat most in their free time. On average, they earned over $ 50,000 a year. Those who spent more time sitting and watching television earned less.

Taken together, these results certainly suggest remarkable differences in sitting and working sitting, but also point to a wider collection of lifestyle factors affecting health. Some people spend more time working and less time working at home because of their job:

"I think that social factors may play an important role here," she explains. "It's possible that socioeconomic status is a factor that higher income and higher education are usually associated with more salaried jobs that are usually located in an office, while there are usually more likely to be workers' jobs.

The more we learn about sitting, the more complicated its impact on our health becomes. One thing that becomes clear is that the time we spend sitting down is an indicator of many other health factors that go beyond the time we spend on our buttocks. Fortunately, for those who spend more time seated than healthy, Garcia's work points to a silver lining: About 30 minutes of moderate to intense exercise can trigger health risks related to sitting.

In this regard, she offers some basic advice: "Even if you do not feel like giving up your favorite TV show, you should take a brisk 30-45 minute walk afterwards!"

Subtotal:

Methods and Results: Participants including 3,592 individuals who participated in the Jackson Heart Study, a community-based study of African Americans resident in Jackson, MS. Television (4 h / d) and professional sitting (never / rarely, sometimes, often / always) were self reported. At a mean follow-up of 8.4 years, there were 129 CVD events and 205 deaths. The highest category of television (> 4 h / d) was associated with a higher risk of combined CVD events / overall mortality endpoint compared to the lowest category (<2 h / d; hazard ratio: 1.49 [95% CI: 1.13-1.97]). , In contrast, the highest category of occupational sitting (often / always) compared to the lowest category (never / rare, hazard ratio: 0.90 [95% CI: 0.69- 1.18]) was not associated with a risk of combined CVD events / overall mortality endpoint. Moderate-Strength Physical Activity (MVPA) mitigated television's association with CVD events / all-cause mortality, so television was not associated with higher risk in people with high MVPA scores.

Conclusions: Television was associated with a higher risk of CVD events and all-cause mortality, whereas occupational sitting had no relation to these findings. These results suggest that minimizing television viewing among African Americans can lower CVD and mortality risk more effectively than reducing sedentary occupational behavior.
