AIt's a company, we sit too much. We sit in the car, sit at our desks and rush to the couch when we get home. But not all places are the same. Each of these approaches to the session poses a very different risk to heart health, according to research published on Wednesday Official of the American Heart Association.
Even if sitting at a desk it can seem the most punitive, the she studies shows that for at least one American population, it is not an occupational session that is taking the greatest toll on heart health. Instead, it is the usual sedentary evening ritual of preparing a meal in front of the TV and looking now after the time of any show selected to fill the void left by game of Thrones.
Analysis of data collected from 3,592 African-Americans enrolled in Study of Jackson's heart revealed that people who spent four or more hours sitting in front of the TV every night were 49 percent more likely having had a heart attack compared to those who spent less than two hours watching TV every day.
In comparison, the people who reported the highest levels of professional session did not have significant changes in their risk of cardiovascular disease compared to people who rarely sat for work, author of the study Jeanette Garcia, Ph.D., an exercise physiologist at the University of Central Florida, says Reverse.
"Although I am not suggesting that there are absolutely no health risks associated with many sessions at work, the results of our study indicate that perhaps we should consider focusing on interventions that interrupt or reduce television viewing at home," says Garcia Reverse.
Sitting at work against sitting at home
The Jackson Heart Study followed the participants for a median of over eight and a half years. During that time there were 129 heart attacks and 205 deaths (they were grouped in this analysis). Garcia noted the pattern of increased risk within the data on those deaths. He thinks it probably has to do with other aspects of sedentary life that are related to spending long hours watching TV.
The big difference between sitting at home against sitting at work is that it tends to happen without interruption. In an office, sitting at a desk can be broken down by daily activities like going to a printer, taking a coffee break, or visiting colleagues. Sitting in front of the TV, meanwhile, is an uninterrupted sedentary time. Garcia notes that there may be additional risks that emerge from the completely uninterrupted sitting time during the TV binge.
"These types of activities can interrupt long periods of sitting, which is better than the prolonged, uninterrupted sedentary time, which can occur more with television, especially at night when you are tired," he says. "Even when you're sitting at your desk, you can be restless or stretched, which may not seem like a lot of movement, but any little help can help."
How the company promotes certain types of sessions
The idleness associated with time sitting apart, a series of additional health behaviors have also been discovered in Garcia's discoveries.
People who spent more time watching TV, for example, were more likely to be less active during leisure time and were more likely to smoke, drink and follow an unhealthy diet. Those with the highest level of professional sitting, meanwhile, had the demographic characteristics of high-income desk workers. They were younger, more likely to follow a healthy diet and recorded more minutes of physical activity in their spare time.
Moreover, the people who sat more for work reasons were in particular More well-off of those who sat more during their free time. They earned over $ 50,000 a year on average; those who spent more time sitting while watching TV did less.
Taken together, these results certainly indicate significant differences in work-based sitting and leisure time sitting, but they are also indicative of a broader collection of lifestyle factors influencing health. Some people, by the nature of their work, spend more time standing at work and less time to waste at home:
"I feel that social factors can play an important role here," he explains. "It is possible that socio-economic status may be a factor in which higher income and education tend to be linked with more white-collar jobs than are typically in an office environment, while jobs from" blue collar "typically tend to be more active."
The more we learn to sit, the more complicated its impact on our health becomes. One thing that is becoming clear is that the time we spend sitting is a signifier of many other health factors besides spending time on our bottom. Fortunately, for those who spend more time sitting than healthy, Garcia's work indicates a silver lining: about 30 minutes of moderate to vigorous exercise can prevent the health risks associated with the session.
On this front, he offers some basic tips: "So even if you don't feel able to give up your favorite TV show, maybe consider a 30-45 minute walk later!"
Methods and results: The participants included 3,592 individuals enrolled in the Jackson Heart Study, a study based on the community of African Americans residing in Jackson, MS. The television viewing (4 hours / day) and the occupational session (never / rarely, sometimes, often / always) have been self-reported. During a median follow-up of 8.4 years, there were 129 CVD events and 205 deaths. The highest television viewing category (> 4 h / d) was associated with a higher risk for composite CVD events / all-cause mortality endpoints than the lower category (<2 h / d; hazard ratio: 1, 49 (95% CI: 1.13-1.97)). On the contrary, the highest category of professional sessions (often / always) was not associated with the risk of composite CVD events / mortality endpoints for all causes compared to the lowest category (never / rarely; hazard ratio: 0.90 (IC 95%: 0.69 – 1.18)). Moderate to vigorous physical activity (MVPA) has moderated the association of television viewing with all-cause CVD / mortality events, whereby television viewing was not associated with greater risk among those with high levels of MVPA.
conclusions: Television viewing was associated with a greater risk of CVD events and all-cause mortality, while the professional session had no association with these results. These results suggest that minimizing television viewing could be more effective for reducing CVD and mortality risk in African Americans than reducing sedentary occupational behavior.
