Sedentary lifestyle

See physical inactivity

Predisposes to adiposity, which promotes inflammation, insulin resistance and hypertension.

There is potential links between sedentary behavior and the range of health risks, including association with both cognitive and structural brain aging.

Sedentary behavior refers to any waking behavior with an energy expenditure of 1.5 metabolic equivalent of task or less in a sitting, reclining, or lying posture and has become more prevalent, and is associated with the range of negative health effects.

Higher levels of moderate and vigorous intensity physical activity daily in children and adolescents is associated with better cardio metabolic risk factors regardless of the amount of sedentary time (Ekelund U et al).

Compared with those who are physically active the risk of cardiovascular disease in sedentary individuals is 150-240% higher.

Remaining sedentary for more than 12 hours daily is linked with a higher risk of death and being sedentary for eight hours, but a little more than 20 minutes of exercise closed the gap.

Choosing a sedentary lifestyle doubles the risk of heart disease.

Prolonged time spent in a sedentary state is one of the key modifiable factors contributing to cardiovascular disease.

Sedentary lifestyle deleteriously affects cardiovascular system and is an independent risk factor for all-cause mortality.

Sedentary behaviors are associated with risk of developing all cause dementia, and the direction of the risk depends on the activity done while sedentary (Rachien D).

There is an association between the amounts of sedentary time in a person’s life and their overall metabolic risk, even if the person attains recommended amount of physical activity.

Prolonged sitting is associated with a higher risk of cardiovascular disease, diabetes, cancer, and overall mortality, particularly among individuals with low levels of physical activity.

Sedentary behavior associated with depression, anxiety, and poor self-esteem.

Associated with increased risk of obesity and type two diabetes.

Leading behavioral preventable causes of death: tobacco use, ETOH abuse, physical inactivity and poor diet.

Sedentary behavior defined as any waking behavior characterized by an energy expenditure that is less than or equal to 1.5 times the resting metabolic rate while in the sitting or reclining posture.

Sedentary time in the US is approximately 7.7 hours daily.

Sedentary time is differentiated from physical inactivity in that physical inactivity refers to insufficient physical activity rather than participating in sedentary behaviors such as sitting or reclining.

Sedentary behavior such as sitting or reclining requires expending 1.0-1.5 times the resting metabolic rate.

The most sedentary age group is 70 years.

Longest sedentary time is associated with adverse health outcomes.

In high income countries, television viewing predominates discretionary sedentary behavior; and is associated with adverse health outcomes.

Prolonged sedentary linked to obesity and other chronic diseases and to all cause mortality and from cardiovascular diseases.

Increased time spent watching TV and sitting increases premature mortality risk.

Significant positive dose response association exists between daily sitting and mortality from all causes as well as from cardiovascular diseases.

Individuals who have a sedentary lifestyle tend to have impaired executive functions relative to other more physically active non-exercisers.

Greater sedentary time is independently associated with cancer mortality risk and replacing sedentary time with light or moderate-vigorous physical activity may be associated with a lower risk of cancer mortality (Gilchrist SC).


Women’s Health Initiative analysis into the impact of increased sedentary behavior on heart failure risk in older women.


The Women’s Health Initiative, contains data on more than nearly 90,000 postmenopausal women.


Women spending 9.5 hours or more sitting or lying down each day had a 42% higher risk of being hospitalized with heart failure than women who spent 6.5 hours or less engaged in sedentary behavior.


The mean reported time spent engaging in sedentary behavior per day was 7 hours. 


11% of patients reported no recreational physical activity. 


When controlling for age, race-ethnicity, education, income, smoking, alcohol, menopausal hormone therapy, and hysterectomy status, results of the analysis indicated heart failure risk increased across incrementals of total sedentary behavior- 6.6-9.5 hours: HR, 1.15; More than 9.5 hours: HR, 1.42; sitting time 4.6-8.5 hours: HR, 1.14, More than 8.5 hours: HR, 1.54.


Associations with sedentary behavior exposures did not differ based on age, race-ethnicity, BMI, physical activity, physical functioning, diabetes, hypertension, or coronary heart disease.


People with more daily sedentary time are more likely to develop chronic health conditions such as diabetes, high blood pressure, heart attack, stroke and premature death from heart disease and other causes.


Sedentary men have a reduced life expectancy of about 5 years, compared with men who were moderately to vigorously physically active.
