The enquiry squad analyzed surveys of 51,000 people from 2001 to 2016 to runway sitting trends inwards front end of TVs as well as computers as well as the full total of fourth dimension spent sitting on a daily basis. Unlike other studies that bring looked at sedentary behaviors, the enquiry is the kickoff to document sitting inwards a nationally representative sample of the U.S.A. population across multiple historic catamenia groups - from children to the elderly - as well as unlike racial as well as ethnic groups.
The research, led yesteryear Yin Cao, ScD, an epidemiologist as well as assistant professor of surgical physical care for inwards the Division of Public Health Sciences, is published Apr 23 inwards the Journal of the American Medical Association.
"In almost none of the groups nosotros analyzed are the numbers going inwards the correct direction," said Cao, the study's senior author. "We desire to heighten awareness most this number on multiple levels -- from individuals as well as families to schools, employers as well as elected officials."
Epidemiologist as well as co-senior writer Graham A. Colditz, MD, DrPH, the Niess-Gain Professor of Surgery as well as manager of the Division of Public Health Sciences, said: "We intend a lot of these sedentary habits are formed early, then if nosotros tin terminate brand changes that aid children hold upwards to a greater extent than active, it could pay off inwards the future, both for children every bit they grow to adulthood as well as for futurity health-care spending. Sedentary behaviour is linked to piteous wellness inwards many areas, as well as if nosotros tin terminate trim down that across the board it could bring a big impact."
The novel study fills a gap inwards noesis on sedentary behavior, according to the researchers, putting specific numbers on the total of fourth dimension Americans genuinely pass sitting. For example, the most recent edition of the Physical Activity Guidelines for Americans, published inwards 2018 yesteryear the Department of Health as well as Human Services, recommends less sitting fourth dimension but offers no guidance on how much.
The researchers analyzed information from to a greater extent than than 51,000 people who participated inwards the National Health as well as Nutrition Examination Survey betwixt 2001 as well as 2016, looking at 4 historic catamenia groups: children ages v to eleven (as reported yesteryear a bring upwards or guardian), adolescents ages 12 to 19, adults ages xx to 64, as well as adults ages 65 as well as older. Race as well as ethnicity were defined every bit non-Hispanic white, non-Hispanic black, Hispanic as well as other races, including multiracial.
Total daily sitting fourth dimension increased amid adolescents as well as adults from 2007 to 2016, from vii hours per hateful solar daytime to only over 8 for teenagers, as well as from 5.5 hours per hateful solar daytime to almost 6.5 for adults, the researchers found.
"Until now, nosotros haven't had information demonstrating the total of fourth dimension most Americans pass sitting watching TV or doing other sedentary activities," Cao said. "Now that nosotros bring a baseline -- on population marking as well as for unlike historic catamenia groups -- nosotros tin terminate await at trends over fourth dimension as well as come across whether unlike interventions or world wellness initiatives are effective inwards reducing the fourth dimension spent sitting as well as nudging people toward to a greater extent than active behaviors."
The researchers flora that most Americans pass at to the lowest degree ii hours per hateful solar daytime sitting as well as watching telly or videos. Among children ages 5-11, 62 per centum spent at to the lowest degree that long inwards front end of screens daily. For adolescents ages 12-19, that number was 59 percent. About 65 per centum of adults ages xx to 64 spent at to the lowest degree ii hours watching telly per day. And most recently, from 2015 to 2016, 84 per centum of adults over historic catamenia 65 spent at to the lowest degree that much fourth dimension sitting watching television. And this remained steady over the course of teaching of the study.
Across all historic catamenia groups, 28 per centum to 38 per centum of those surveyed spent at to the lowest degree 3 hours per hateful solar daytime watching telly or videos, as well as xiii per centum to 23 per centum spent 4 hours or to a greater extent than engaged inwards watching telly or videos.
Importantly, males of all historic catamenia groups, non-Hispanic dark individuals of all historic catamenia groups as well as participants who reported beingness fat or physically inactive were to a greater extent than probable to pass to a greater extent than fourth dimension sitting to spotter televisions or videos compared to their counterparts.
In addition, estimator covert fourth dimension exterior of operate as well as schoolhouse increased over this period. At to the lowest degree one-half of individuals across all historic catamenia groups used a estimator during leisure fourth dimension for to a greater extent than than 1 hr per hateful solar daytime inwards the ii most recent years of the study. And upwards to a quarter of the U.S.A. population used computers exterior of operate as well as schoolhouse for 3 hours or more.
"How nosotros exercise world policies or promote social alter that supports less sitting is unclear as well as probable to hold upwards complicated," Colditz said. "If a neighborhood inwards a disadvantaged community is unsafe, for example, parents can't only post their kids exterior to play. Our environments -- the agency our cities, our schoolhouse days as well as working days are designed -- play roles inwards this behaviour that are hard to change. But at to the lowest degree now, nosotros bring a baseline from which to mensurate whether specific changes are having an impact."
Chao Cao, a recent graduate of the Brown School as well as a information analyst inwards Yin Cao's lab, co-led the analyses. Washington University also collaborated amongst researchers at a number of other institutions, including Charles Matthews, PhD, at the National Cancer Institute (NCI); Lin Yang, PhD, at the Alberta Health Services, Calgary, Canada; the Harvard T.H. Chan School of Public Health; Memorial Sloan Kettering Cancer Center; as well as Massachusetts General Hospital as well as Harvard Medical School. Sumber http://healthnewsreport.blogspot.com/
