What Allowed Some Human Groups To Beco E Sedentary
From Wikipedia, the free encyclopedia For the lifestyle associated with poor health outcomes, see Sedentary lifestyle, Look up sedentism in Wiktionary, the free dictionary. In cultural anthropology, sedentism (sometimes called sedentariness ; compare sedentarism ) is the practice of living in one place for a long time. As of 2023, the large majority of people belong to sedentary cultures.

What group of people were sedentary?

Natufians and Sedentism – The earliest potentially sedentary society on our planet was the Mesolithic Natufian, located in the Near East between 13,000 and 10,500 years ago ( BP ). However, much debate exists about their degree of sedentism. Natufians were more or less egalitarian hunter-gatherers whose social governance shifted as they shifted their economic structure.

By about 10,500 BP, the Natufians developed into what archaeologists call Early Pre-Pottery Neolithic as they increased in population and reliance on domesticated plants and animals and began living in at least partially year-round villages. These processes were slow, over periods of thousands of years with intermittent fits and starts.

Sedentism arose, quite independently, in other areas of our planet at different times. But like the Natufians, societies in places such as Neolithic China, South America’s Caral-Supe, the North American Pueblo societies, and the precursors to the Maya at Ceibal all changed slowly and at different rates over a long period of time.

What is sedentary human civilization?

From Wikipedia, the free encyclopedia This article is about the medical term. For the anthropologic concept, see sedentism, Exercise trends such as watching television are a common characteristic of a sedentary lifestyle Sedentary lifestyle is a lifestyle type, in which one is physically inactive and does little or no physical movement and or exercise. A person living a sedentary lifestyle is often sitting or lying down while engaged in an activity like socializing, watching TV, playing video games, reading or using a mobile phone or computer for much of the day.

A sedentary lifestyle contributes to poor health quality, diseases as well as many preventable causes of death,
Sitting time is a common measure of a sedentary lifestyle.
A global review representing 47% of the global adult population found that the average person sits down for 4.7 to 6.5 hours a day with the average going up every year.

The CDC found that 25.3% of all American adults are physically inactive. Screen time is a term for the amount of time a person spends looking at a screen such as a television, computer monitor, or mobile device. Excessive screen time is linked to negative health consequences.

Are people becoming more sedentary?

Conclusion – In recent decades, affluent populations have become increasingly sedentary, with many adults spending 70% or more of their waking hours sitting. Parallel with this change, evidence has emerged identifying habitual sedentary behavior (prolonged sitting) as a novel risk factor for cardiometabolic disease and all-cause mortality, independent of time spent in exercise.

As this evidence is primarily observational in nature, further experimental research investigating potential mechanisms and dose-response relationships is necessary.
For example, a daily quantity of neuromuscular stimulation (some combination of duration and frequency) that occurs during standing and light activities may be necessary to sustain components of musculoskeletal and metabolic health.

These new insights into the health risks of sedentary behavior broaden the accepted perspective on physical activity and health by identifying the need to reduce prolonged sitting and increase light-intensity activities (eg, standing and incidental walking), in addition to engaging in regular moderate-to-vigorous activity.

The importance of exercise counseling in the primary care setting is well established.25 Excellent resources providing practical advice for incorporating behavioral counseling in medical settings are available.26, 27 In light of recent findings, it has become clear that most patients face 2 obstacles: too little exercise and too much sitting.

The American Academy of Pediatrics counsels parents to limit children’s screen time—television, DVDs, and video games—to no more than 2 hours per day.28 Parents still tell their children to get off the sofa and go out and play. Recent evidence is compelling that adults too need similar advice from their physicians.

When did humans become sedentary?

When Humans Quit Hunting And Gathering, Their Bones Got Wimpy – What Allowed Some Human Groups To Beco E Sedentary Farming helped fuel the rise of civilizations, but it may also have given us less robust bones. Leemage/UIG via Getty Images hide caption toggle caption Leemage/UIG via Getty Images Farming helped fuel the rise of civilizations, but it may also have given us less robust bones. Leemage/UIG via Getty Images Compared with other primates and our early human ancestors, we modern humans have skeletons that are relatively lightweight — and scientists say that basically may be because we got lazy.

Biological anthropologist Habiba Chirchir and her colleagues at the Smithsonian’s National Museum of Natural History were studying the bones of different primates including humans. When they looked at the ends of bones near the joints, where the inside of the bone looks almost like a sponge, they were struck by how much less dense this spongy bone was in humans compared with chimpanzees or orangutans.

“So the next step was, what about the fossil record? When did this feature evolve?” Chirchir wondered. Their guess was that the less dense bones showed up a couple of million years ago, about when Homo erectus, a kind of proto-human, left Africa. Having lighter bones would have made it a lot easier to travel long distances, Chirchir speculated. But after examining a bunch of early human fossils, she realized their guess was wrong.

“This was absolutely surprising to us,” she says. “The change is occurring much later in our history.” The lightweight bones don’t appear until about 12,000 years ago. That’s right when humans were becoming less physically active because they were leaving their nomadic hunter-gatherer life behind and settling down to pursue agriculture.

A report on the work appeared Monday in the Proceedings of the National Academy of Sciences, along with a study from a different research group that came to much the same conclusion. Those researchers looked at the bones of people in more recent history who lived in farming villages nearly 1,000 years ago and compared them with the bones of people who had lived nearby, earlier, as foragers. The bones of people from the farming communities were less strong and less dense than those of the foragers, whose measured bone strength was comparable to similar-size nonhuman primates.

Where did sedentary come from?

What Allowed Some Human Groups To Beco E Sedentary 29th Jul 2016 Sedentary Scientists have recently warned that a sedentary lifestyle may be as dangerous to our health as smoking. As Collins Cobuild Dictionary explains, someone who has a sedentary lifestyle or job sits down a lot of the time and does not take much exercise.

The origin of the word lies in the Latin verb sedere, which means ‘to sit’. This root word produced two Latin adjectives: sedens, which is quite common in Latin and just means ‘sitting’, and sedentarius, which is rarer and has the more specific meaning of ‘tending to sit around a lot’. These words found their way into English as ‘sedent’ and ‘sedentary’ respectively.

However, in English it is ‘sedent’ that is the rare word. (After all, why use ‘sedent’ when you can say ‘sitting’?) On the other hand, the more specific word ‘sedentary’ has come into its own as we find ourselves increasingly in need of a word that describes our tendency to sit down and stare at a screen all day. What Allowed Some Human Groups To Beco E Sedentary

Why did early humans become sedentary?

Early humans started walking to avoid predators and look for food. Once those tasks were secured, it was time to rest, perform art and science to make tasks easier.

How did the sedentary people lived?

Before, all people were nomadic, meaning they had to continually move to find food. With agriculture, many humans developed sedentary societies, meaning they stayed in one place to build sturdy, non-mobile homes. Suddenly, the small bands of people grew into large communities and, eventually, cities.

Did human began to develop a sedentary type of society during the Neolithic Revolution?

This article is about the introduction of agriculture during the Stone Age. For later historical breakthroughs in agriculture, see Agricultural revolution (disambiguation), Map of Southwest Asia showing the main archaeological sites of the Pre-Pottery Neolithic period, c. 7500 BC, The Neolithic Revolution, or the ( First ) Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible.

These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops, Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene 11,700 years ago.

It was the world’s first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in the quality of human nutrition compared with that obtained previously from foraging, but because food production became more efficient, it released humans to invest their efforts in other activities and was thus “ultimately necessary to the rise of modern civilization by creating the foundation for the later process of industrialization and sustained economic growth.” The Neolithic Revolution involved far more than the adoption of a limited set of food-producing techniques.

During the next millennia it transformed the small and mobile groups of hunter-gatherers that had hitherto dominated human pre-history into sedentary (non- nomadic ) societies based in built-up villages and towns.
These societies radically modified their natural environment by means of specialized food-crop cultivation, with activities such as irrigation and deforestation which allowed the production of surplus food.

Other developments that are found very widely during this era are the domestication of animals, pottery, polished stone tools, and rectangular houses. In many regions, the adoption of agriculture by prehistoric societies caused episodes of rapid population growth, a phenomenon known as the Neolithic demographic transition,

These developments, sometimes called the Neolithic package, provided the basis for centralized administrations and political structures, hierarchical ideologies, depersonalized systems of knowledge (e.g.
Writing ), densely populated settlements, specialization and division of labour, more trade, the development of non-portable art and architecture, and greater property ownership.

The earliest known civilization developed in Sumer in southern Mesopotamia ( c. 6,500 BP ); its emergence also heralded the beginning of the Bronze Age, The relationship of the aforementioned Neolithic characteristics to the onset of agriculture, their sequence of emergence, and empirical relation to each other at various Neolithic sites remains the subject of academic debate, and varies from place to place, rather than being the outcome of universal laws of social evolution,

What happens when you become sedentary?

If you live a sedentary lifestyle, you have a higher chance of being overweight, developing type 2 diabetes or heart disease, and experiencing depression and anxiety.

What is the most common type of sedentary behavior?

Sedentary behavior is any waking behavior characterized by an energy expenditure ≤1.5 metabolic equivalents (METs), while in a sitting, reclining or lying posture. In general this means that any time a person is sitting or lying down, they are engaging in sedentary behaviour.

Common sedentary behaviours include TV viewing, video game playing, computer use (collective termed “screen time”), driving automobiles, and reading. This definition of sedentary behaviour has been published in the International Journal of Behavioral Nutrition and Physical Activity, You can access the full paper at the following link: ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0525-8,

Why do we care about sedentary behaviour? Recent evidence suggests that having a high level of sedentary behaviour negatively impacts health independent of other factors including body weight, diet, and physical activity.
For example, a 12-year study of 17,000 Canadian adults found that those who spent most of their time sitting were 50% more likely to die during the follow-up than those that sit the least, even after controlling for age, smoking, and physical activity levels.

Given these and other findings, researchers are now studying the health impact of sedentary behaviour in a wide range of academic domains including epidemiology, population health, psychology, ergonomics, engineering, and physiology. You can find links to other recent studies on sedentary behaviour on our Research page, while you can read more detailed study descriptions on our Study Summaries page.

What happens if you never exercise?

Not getting enough physical activity can lead to heart disease —even for people who have no other risk factors. It can also increase the likelihood of developing other heart disease risk factors, including obesity, high blood pressure, high blood cholesterol, and type 2 diabetes.

Which country is the most sedentary?

Asia – In general, Asian countries have decreasing prevalence of activity due to mechanization of work and transport and the spread of sedentary lifestyle. The prevalence of obesity and physical inactivity are both generally high in Asia at around 60%, with Saudi Arabia with the lowest physical activity in the world at 39%.

Which gender is more sedentary?

Results – Men accumulated more sedentary time than women in 1+, 5+, 10+, 20+, 30+, 40+, 50+ and 60+ minute bouts; the largest gender-differences were observed in 10+ and 20+ minute bouts. Age was positively associated with sedentary time, but only in bouts of 10+, 20+, 30+, and 40+ minutes.

Why did people stop being nomadic?

Hunting for Game – The Hadza people of Tanzania rely on hunting wild game for meat, a task that requires great skill in tracking, teamwork, and accuracy with a bow and arrow. Photograph by Matthieu Paley What Allowed Some Human Groups To Beco E Sedentary Hunter-gatherer culture is a type of subsistence lifestyle that relies on hunting and fishing animals and foraging for wild vegetation and other nutrients like honey, for food. Until approximately 12,000 years ago, all humans practiced hunting-gathering.

Anthropologists have discovered evidence for the practice of hunter-gatherer culture by modern humans ( Homo sapiens ) and their distant ancestors dating as far back as two million years. Before the emergence of hunter-gatherer cultures, earlier groups relied on the practice of scavenging animal remains that predators left behind.

Because hunter-gatherers did not rely on agriculture, they used mobility as a survival strategy, Indeed, the hunter-gatherer lifestyle required access to large areas of land, between seven and 500 square miles, to find the food they needed to survive.

This made establishing long-term settlements impractical, and most hunter-gatherers were nomadic,
Hunter-gatherer groups tended to range in size from an extended family to a larger band of no more than about 100 people.
With the beginnings of the Neolithic Revolution about 12,000 years ago, when agricultural practices were first developed, some groups abandoned hunter-gatherer practices to establish permanent settlements that could provide for much larger populations.

However, many hunter-gatherer behaviors persisted until modern times. As recently as 1500 C.E., there were still hunter-gatherers in parts of Europe and throughout the Americas. Over the last 500 years, the population of hunter-gatherers has declined dramatically.

Today very few exist, with the Hadza people of Tanzania being one of the last groups to live in this tradition, The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.

What makes people stop being nomadic?

With the invention of agriculture, people were able to cultivate food in one place so that there was no more need to move around in order to find food. It is at this point in human history that more and more people became settled rather than nomadic.

Is sedentary lifestyle genetic?

Background – Physical inactivity and sedentariness represent a major challenge to public health and contribute substantially to ill health and premature mortality, The impact of physical inactivity on development of non-communicable diseases has been compared to that of tobacco smoking, alcohol consumption, or an unhealthy diet,

In contrast, there is ample evidence that a physically active lifestyle is associated with a myriad of health benefits, Despite this, a large proportion of the population remains inactive below the recommended levels of physical activity, Although the variation in physical activity and sedentariness is likely to be determined by a multitude of factors, evidence from family- and twin studies suggest a significant genetic influence,

Recent developments in both objective measurements of physical activity and sedentary behaviour, along with improved genotyping technology facilitating extensive genotyping in large populations, give promise for the identification of valid and robust genotype-phenotype associations of physical activity and sedentary behaviour.

These associations may in turn serve as genetic instruments in Mendelian randomisation studies to improve causal inference about the health effects of physical activity and sedentariness, and thus guide the development of effective preventive strategies and interventions. Previous reviews have reported associations between different physical activity and sedentary behavior phenotypes and various genes,

However, most reviews did not describe a systematic literature search and no previous review has conducted a quality assessment to critically assess the methodological quality of the included studies, which is recommended for systematic reviews of genetic association studies,

Are people becoming less active?

Physical activity

Physical activity has significant health benefits for hearts, bodies and minds Physical activity contributes to preventing and managing noncommunicable diseases such as cardiovascular diseases, cancer and diabetes Physical activity reduces symptoms of depression and anxiety Physical activity enhances thinking, learning, and judgment skills Physical activity ensures healthy growth and development in young people Physical activity improves overall well-being Globally, 1 in 4 adults do not meet the global recommended levels of physical activity People who are insufficiently active have a 20% to 30% increased risk of death compared to people who are sufficiently active More than 80% of the world’s adolescent population is insufficiently physically active

WHO defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure. Physical activity refers to all movement including during leisure time, for transport to get to and from places, or as part of a person’s work.

Both moderate- and vigorous-intensity physical activity improve health. Popular ways to be active include walking, cycling, wheeling, sports, active recreation and play, and can be done at any level of skill and for enjoyment by everybody. Regular physical activity is proven to help prevent and manage noncommunicable diseases such as heart disease, stroke, diabetes and several cancers.

It also helps prevent hypertension, maintain healthy body weight and can improve mental health, quality of life and well-being. WHO guidelines and recommendations provide details for different age groups and specific population groups on how much physical activity is needed for good health.

be physically active several times a day in a variety of ways, particularly through interactive floor-based play; more is better. For those not yet mobile, this includes at least 30 minutes in prone position (tummy time) spread throughout the day while awake; not be restrained for more than 1 hour at a time (e.g., prams/strollers, high chairs, or strapped on a caregiver’s back);

Screen time is not recommended.

When sedentary, engaging in reading and storytelling with a caregiver is encouraged; and have 14-17h (0-3 months of age) or 12-16h (4-11 months of age) of good quality sleep, including naps.

In a 24-hour day, children 1-2 years of age should:

spend at least 180 minutes in a variety of types of physical activities at any intensity, including moderate- to vigorous-intensity physical activity, spread throughout the day; more is better; not be restrained for more than 1 hour at a time (e.g., prams/strollers, high chairs, or strapped on a caregiver’s back) or sit for extended periods of time.

For 1 year olds, sedentary screen time (such as watching TV or videos, playing computer games) is not recommended. For those aged 2 years, sedentary screen time should be no more than 1 hour; less is better.

When sedentary, engaging in reading and storytelling with a caregiver is encouraged; and have 11-14h of good quality sleep, including naps, with regular sleep and wake-up times.

In a 24-hour day, children 3-4 years of age should:

spend at least 180 minutes in a variety of types of physical activities at any intensity, of which at least 60 minutes is moderate- to vigorous-intensity physical activity, spread throughout the day; more is better; not be restrained for more than 1 hour at a time (e.g., prams/strollers) or sit for extended periods of time.

Sedentary screen time should be no more than 1 hour; less is better.

When sedentary, engaging in reading and storytelling with a caregiver is); encourage; and have 10-13h of good quality sleep, which may include a nap, with regular sleep and wake-up times.

Children and adolescents aged 5-17 years

should do at least an average of 60 minutes per day of moderate-to-vigorous intensity, mostly aerobic, physical activity, across the week. should incorporate vigorous-intensity aerobic activities, as well as those that strengthen muscle and bone, at least 3 days a week. should limit the amount of time spent being sedentary, particularly the amount of recreational screen time.

should do at least 150–300 minutes of moderate-intensity aerobic physical activity; or at least 75–150 minutes of vigorous-intensity aerobic physical activity; or an equivalent combination of moderate- and vigorous-intensity activity throughout the week should also do muscle-strengthening activities at moderate or greater intensity that involve all major muscle groups on 2 or more days a week, as these provide additional health benefits. may increase moderate-intensity aerobic physical activity to more than 300 minutes; or do more than 150 minutes of vigorous-intensity aerobic physical activity; or an equivalent combination of moderate- and vigorous-intensity activity throughout the week for additional health benefits. should limit the amount of time spent being sedentary. Replacing sedentary time with physical activity of any intensity (including light intensity) provides health benefits, and to help reduce the detrimental effects of high levels of sedentary behaviour on health, all adults and older adults should aim to do more than the recommended levels of moderate- to vigorous-intensity physical activity

Adults aged 65 years and above

Same as for adults; and as part of their weekly physical activity, older adults should do varied multicomponent physical activity that emphasizes functional balance and strength training at moderate or greater intensity, on 3 or more days a week, to enhance functional capacity and to prevent falls.

Pregnant and postpartum women All pregnant and postpartum women without contraindication should:

do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week incorporate a variety of aerobic and muscle-strengthening activities should limit the amount of time spent being sedentary. Replacing sedentary time with physical activity of any intensity (including light intensity) provides health benefits.

People living with chronic conditions (hypertension, type 2 diabetes, HIV and cancer survivors)

should do at least 150–300 minutes of moderate-intensity aerobic physical activity; or at least 75–150 minutes of vigorous-intensity aerobic physical activity; or an equivalent combination of moderate- and vigorous-intensity activity throughout the week should also do muscle-strengthening activities at moderate or greater intensity that involve all major muscle groups on 2 or more days a week, as these provide additional health benefits. as part of their weekly physical activity, older adults should do varied multicomponent physical activity that emphasizes functional balance and strength training at moderate or greater intensity, on 3 or more days a week, to enhance functional capacity and to prevent falls. may increase moderate-intensity aerobic physical activity to more than 300 minutes; or do more than 150 minutes of vigorous-intensity aerobic physical activity; or an equivalent combination of moderate- and vigorous-intensity activity throughout the week for additional health benefits. should limit the amount of time spent being sedentary. Replacing sedentary time with physical activity of any intensity (including light intensity) provides health benefits, and to help reduce the detrimental effects of high levels of sedentary behaviour on health, all adults and older adults should aim to do more than the recommended levels of moderate- to vigorous-intensity physical activity.

Children and adolescents living with disability:

Adults living with disability:

should do at least 150–300 minutes of moderate-intensity aerobic physical activity; or at least 75–150 minutes of vigorous-intensity aerobic physical activity; or an equivalent combination of moderate- and vigorous-intensity activity throughout the week should also do muscle-strengthening activities at moderate or greater intensity that involve all major muscle groups on 2 or more days a week, as these provide additional health benefits.

Replacing sedentary time with physical activity of any intensity (including light intensity) provides health benefits, and to help reduce the detrimental effects of high levels of sedentary behaviour on health, all adults and older adults should aim to do more than the recommended levels of moderate- to vigorous-intensity physical activity. It is possible to avoid sedentary behaviour and be physically active while sitting or lying.E.g. Upper body led activities, inclusive and/or wheelchair-specific sport and activities.

Regular physical activity, such as walking, cycling, wheeling, doing sports or active recreation, provides significant benefits for health. Some physical activity is better than doing none. By becoming more active throughout the day in relatively simple ways, people can easily achieve the recommended activity levels.

improve muscular and cardiorespiratory fitness; improve bone and functional health; reduce the risk of hypertension, coronary heart disease, stroke, diabetes, various types of cancer (including breast cancer and colon cancer), and depression; reduce the risk of falls as well as hip or vertebral fractures; and help maintain a healthy body weight.

In children and adolescents, physical activity improves:

physical fitness (cardiorespiratory and muscular fitness) cardiometabolic health (blood pressure, dyslipidaemia, glucose, and insulin resistance) bone health cognitive outcomes (academic performance, executive function) mental health (reduced symptoms of depression) reduced adiposity

In adults and older adults, higher levels of physical activity improves:

risk of all-cause mortality risk of cardiovascular disease mortality incident hypertension incident site-specific cancers (bladder, breast, colon, endometrial, oesophageal adenocarcinoma, gastric and renal cancers) incident type-2 diabetes prevents of falls mental health (reduced symptoms of anxiety and depression) cognitive health sleep measures of adiposity may also improve

For pregnant and post-partum women Physical activity confers the following maternal and fetal health benefits: a decreased risk of:

pre-eclampsia, gestational hypertension, gestational diabetes (for example 30% reduction in risk) excessive gestational weight gain, delivery complications postpartum depression newborn complications, and physical activity has no adverse effects on birthweight or increased risk of stillbirth.

Health risks of sedentary behaviour Lives are becoming increasingly sedentary, through the use of motorized transport and the increased use of screens for work, education and recreation. Evidence shows higher amounts of sedentary behaviour are associated with the following poor health outcomes: In children and adolescents:

increased adiposity (weight gain) poorer cardiometabolic health, fitness, behavioural conduct/pro-social behaviour reduced sleep duration

all-cause mortality, cardiovascular disease mortality and cancer mortality incidence of cardiovascular disease, cancer and type-2 diabetes.

Why most of the population is living a sedentary lifestyle?

What has prompted this sedentary behaviour? – Of the many positive changes that have taken place in our generation during the 21st century, one of the negative aspects has been in the form of an emerging and increasing trend in a sedentary lifestyle. Compared to our grandparents or parents, there is a significant decrease in physical activity and an increase in health complications. What Allowed Some Human Groups To Beco E Sedentary Some of the reasons why this inactivity has increased are:

Rise in desk jobs coupled with emerging technologies in the last few decades, such as laptops and desktops
An increasing amount of time spent on the phone and social media
Hours spent sitting during commute time to work
Long work hours (being a workaholic)
Rise in-home delivery cultures has cut down on people’s need to visit stores physically

Now that we have significantly discussed what a sedentary lifestyle means let us illustrate the effects of physical inactivity on health.

Obesity

Obesity has struck people across the age spectrum, and it is an ailment that opens up your body to a horde of other illnesses. It is no secret that obesity rates are soaring. Inactivity, coupled with a terrible diet, is to blame.

Type 2 Diabetes

Inactivity can make your body resistant to insulin, which makes the body susceptible to diabetes. Diabetes, too, is a lethal disease that will drastically lower your standard of living and, unless kept under check, will prove to be fatal.

High Blood Pressure and thickening of blood vessel walls-

A sedentary lifestyle means you are not getting the exercise your body needs to stay in prime shape. This is when plaque begins to accumulate along your blood vessels. This thickens them, and they further lose their elasticity. That is when blood has to force its way through the narrowed passages, which exerts excessive force on the blood vessels. This results in high blood pressure.

What age group is the most sedentary?

Why are adults sedentary? – November 17, 2017 Today’s post comes from Dr Jennifer Copeland, and Dr Shilpa Dogra. More information on the authors can be found at the bottom of this post. We often hear about the health consequences of excessive screen time in children, and too much sitting among adults working in office settings.

But what about older adults? People over the age of 60 face unique health challenges, such as age-associated declines in physical and cognitive function; prolonged periods of muscular unloading- that is, excessive sitting- could exacerbate these declines.
For example, using Canadian data we found that taking fewer breaks in sedentary time was associated with lower cardiorespiratory fitness in adults aged 60-79 years,

Older adults are a diverse group with a range of abilities, but we know that physical activity levels decline with increasing age. In fact, people over 60 are the least active and accumulate the most sedentary time of any other age group, regardless of whether they are working or not,

These low levels of physical activity could mean that prolonged sedentary time has an even greater effect on health and wellness compared to more active young adults or youth. Given that globally there will be more than two billion older adults by the year 2050, understanding the relationship between sedentary time and healthy ageing is urgent and important.

When a field is in its early stages, and when there are pressing practice implications, scientific consensus is needed to ensure that there is a collective effort to move the field forward. We therefore decided to lead an international group through a critical review and consensus process,

Experts in the area of sedentary behaviour and aging from five countries came together to examine the current state of evidence and set priorities for future research. Here we have highlighted some of the conclusions that resulted from the process. What We Know: Similar to younger adults, sedentary time is associated with an increased risk of mortality and cardiometabolic disease in older adults,

While these outcomes are important, there are other conditions and challenges that are particularly relevant to an older population. These include impairments in physical and cognitive function, poor mental health, incontinence, and problems with sleep.

These non-disease outcomes strongly impact the quality of life of older adults, so we wanted to know if reducing sedentary time could improve these geriatric-relevant outcomes. As is often the case, critically reviewing the literature revealed that the quality of available evidence is generally low. While there is research to suggest that sedentary time and breaks in sedentary time are associated with physical function, there is little information available on other geriatric-relevant outcomes.

Some studies have suggested an inverse relationship between sedentary time and cognitive function, but the evidence is not sufficient to draw any conclusions. Interestingly, some sedentary behaviours that are cognitively-engaging– like reading, using the internet, socializing – may actually benefit the health and wellness of older adults.

But in order to confirm that suggestion, we need measurement tools that can accurately and reliably measure both the volume of sedentary time, the type of sedentary behaviour, and the context in which it is accumulated.
Importantly, there is a lack of longitudinal evidence looking specifically at these geriatric-relevant outcomes.

Furthermore, none of these outcomes were assessed consistently in intervention studies. So although we know that individual behavior change interventions can reduce sitting time among older adults, we can’t say whether this change in behaviour impacts health or quality of life.

Where We Need To Go: First and foremost, it is clear that when conducting research with older adults, we need to move beyond typical disease outcomes and study the issues that have a major impact on quality of life. It is also clear that interventions need to start assessing health outcomes instead of behaviour change alone.

When assessing sedentary behaviour, we must consider not only the volume but also the context in which sedentary time is accumulated, and therefore, need to work on creating tools that can provide this information. We also need to explore and compare the different effects of changing sedentary behaviour in men and women, in the young-old and oldest-old adults, and across the mobility spectrum.

Finally, we are clearly at a point where sedentary time should be integrated into movement behavior guidelines for older adults.
Although more work is needed to develop specific evidence-informed recommendations, the expert panel strongly agreed that older adults would benefit from sitting less, breaking up their sitting time, and moving more.

There is still a lot to learn about the relationship between sedentary behavior and healthy ageing. Our hope with this review and consensus paper is that researchers in the area will consider some of the issues we identified, and that funders will recognize the importance of these priorities.

What age group is the most sedentary?

But what about older adults? People over the age of 60 face unique health challenges, such as age-associated declines in physical and cognitive function; prolonged periods of muscular unloading- that is, excessive sitting- could exacerbate these declines. For example, using Canadian data we found that taking fewer breaks in sedentary time was associated with lower cardiorespiratory fitness in adults aged 60-79 years,

These low levels of physical activity could mean that prolonged sedentary time has an even greater effect on health and wellness compared to more active young adults or youth. Given that globally there will be more than two billion older adults by the year 2050, understanding the relationship between sedentary time and healthy ageing is urgent and important.

Experts in the area of sedentary behaviour and aging from five countries came together to examine the current state of evidence and set priorities for future research.
Here we have highlighted some of the conclusions that resulted from the process.
What We Know: Similar to younger adults, sedentary time is associated with an increased risk of mortality and cardiometabolic disease in older adults,

These non-disease outcomes strongly impact the quality of life of older adults, so we wanted to know if reducing sedentary time could improve these geriatric-relevant outcomes.
As is often the case, critically reviewing the literature revealed that the quality of available evidence is generally low.
While there is research to suggest that sedentary time and breaks in sedentary time are associated with physical function, there is little information available on other geriatric-relevant outcomes.

But in order to confirm that suggestion, we need measurement tools that can accurately and reliably measure both the volume of sedentary time, the type of sedentary behaviour, and the context in which it is accumulated.
Importantly, there is a lack of longitudinal evidence looking specifically at these geriatric-relevant outcomes.

Where We Need To Go: First and foremost, it is clear that when conducting research with older adults, we need to move beyond typical disease outcomes and study the issues that have a major impact on quality of life.
It is also clear that interventions need to start assessing health outcomes instead of behaviour change alone.

Finally, we are clearly at a point where sedentary time should be integrated into movement behavior guidelines for older adults. Although more work is needed to develop specific evidence-informed recommendations, the expert panel strongly agreed that older adults would benefit from sitting less, breaking up their sitting time, and moving more.

Were Neolithic people sedentary?

Causes of the Neolithic Revolution – There was no single factor that led humans to begin farming roughly 12,000 years ago. The causes of the Neolithic Revolution may have varied from region to region. The Earth entered a warming trend around 14,000 years ago at the end of the last Ice Age.

Some scientists theorize that climate changes drove the Agricultural Revolution. In the Fertile Crescent, bounded on the west by the Mediterranean Sea and on the east by the Persian Gulf, wild wheat and barley began to grow as it got warmer. Pre-Neolithic people called Natufians started building permanent houses in the region.

Other scientists suggest that intellectual advances in the human brain may have caused people to settle down. Religious artifacts and artistic imagery—progenitors of human civilization—have been uncovered at the earliest Neolithic settlements. The Neolithic Era began when some groups of humans gave up the nomadic, hunter-gatherer lifestyle completely to begin farming.

Were hunter-gatherers were sedentary?

Indeed, the hunter-gatherer lifestyle required access to large areas of land, between seven and 500 square miles, to find the food they needed to survive. This made establishing long-term settlements impractical, and most hunter-gatherers were nomadic.

Who is the most sedentary population?

All states and territories had more than 15% of adults who were physically inactive and this estimate ranged from 17.3 to 47.7%, according to new state maps of adult physical inactivity prevalence released today by the Centers for Disease Control and Prevention (CDC).

Physical inactivity for adults is defined as not participating in any leisure-time physical activities over the last month – activities such as running, walking for exercise, or gardening.
State and territory-level estimates of physical inactivity range from 17.3% of people in Colorado to 47.7% in Puerto Rico.

In seven states and two territories (Alabama, Arkansas, Kentucky, Louisiana, Mississippi, Oklahoma, Tennessee, Puerto Rico, and Guam), 30% or more of adults were physically inactive. By region, the South had the highest prevalence of physical inactivity (28%), followed by the Northeast (25.6%), Midwest (25%), and the West (20.5%).

Too many adults are inactive, and they may not know how much it affects their health,” said Ruth Petersen, MD, Director of CDC’s Division of Nutrition, Physical Activity, and Obesity.
Being physically active helps you sleep better, feel better and reduce your risk of obesity, heart disease, type 2 diabetes, and some cancers,” The new maps are based on combined 2015-2018 data from the Behavioral Risk Factor Surveillance System (BRFSS), an on-going state-based telephone interview survey conducted by CDC and state health departments.

This is the first time that CDC has created state maps of physical inactivity by race and ethnicity. The demographics of physical inactivity The maps point to notable differences in physical inactivity levels by race and ethnicity. Overall, Hispanics had the highest prevalence of self-reported physical inactivity (31.7%), followed by non-Hispanic blacks (30.3%) and non-Hispanic whites (23.4%).

Five states and Puerto Rico had a physical inactivity prevalence of 30% or higher among non-Hispanic white adults.22 states and Puerto Rico had a physical inactivity prevalence of 30% or higher among Hispanic adults.23 states and the District of Columbia had a physical inactivity prevalence of 30% or higher among non-Hispanic black adults.

Inactivity contributes to 1 in 10 premature deaths in the U.S. Inadequate levels of physical activity are associated with $117 billion in annual healthcare costs. What more can be done? CDC is working with communities and partners across the country as part of the Active People, Healthy Nation SM initiative, to make it easier, safer, and more convenient for people to be active where they live, learn, work and play.

The overall goal of the initiative is to help 27 million Americans become more physically active by 2027 to improve overall health and quality of life and to reduce healthcare costs. The Physical Activity Guidelines for Americans, 2 nd edition, recommends that adults get at least 150 minutes of moderate-intensity physical activity each week.

For example, this can be broken into smaller amounts such as 25 minutes every day or 30 minutes/five times a week. Individuals and families are encouraged to build physical activity into their day by going for a brisk walk or a hike, walking the dog, choosing the stairs instead of the elevator or escalator, parking further away in the parking lot, walking or cycling to run errands, and getting off the bus one stop early and walking the rest of the way.

The key is to move more and sit less.
The initiative helps community leaders take advantage of proven strategies to make physical activity safe and enjoyable for people of all ages and abilities.
Building active and walkable communities may also help support local economies and create more cohesive communities.

Community leaders can also encourage school and youth physical activity programs, educate, and support families and individuals to be more active. They can create activity-friendly routes to everyday destinations such as home, work, school, and grocery stores.

Together, leaders and community members can work with various populations to design and implement culturally-relevant solutions to reduce disparities in physical inactivity.
