Sedentary Time Operational Definition

The sedentary time operational definition used throughout the WHO 2020 Global guidelines on physical activity and sedentary behaviour document was developed through WHO International Classification of Functioning Disability and Health (ICF) framework consultation with input across multiple WHO collaborating centers for physical activity surveillance. The definition has three independent criteria that must all be satisfied simultaneously for a waking behavior to count toward sedentary time accumulation. First, the behavior must occur during waking hours, thereby sleep is explicitly excluded from sedentary time accounting. Second, the behavior metabolic equivalent task intensity must be less than or equal to 1.5 metabolic equivalents (METs), measured by indirect calorimetry reference standards. Third, the body posture must be sitting, reclining, or lying; standing still as a distinct posture category is explicitly not sitting therefore standing posture is explicitly not sitting therefore standing still is not counted as sedentary per WHO definition even though its MET intensity may fall below 1.5 METs in some posture classification schemes.

The 1.5 MET threshold separating sedentary behavior from light intensity physical activity is the consensus cutoff adopted by the Compendium of Physical Activities classification system maintained by the Arizona State University College of Health Solutions. The Compendium coding assigns specific MET values to specific activities: sitting quietly is coded 1.3 METs, sitting reading is coded 1.3 METs, sitting writing or typing on a laptop computer is coded 1.5 METs, standing quietly standing is coded 1.8 METs, light intensity ambulation walking 2.5 miles per hour slow walk is coded 2.5 to 2.8 METs which places firmly in the light intensity physical activity range. WHO classification. Sitting in a motor vehicle during commuting is coded 1.3 METs; reclining awake watching a screen is coded 1.3 METs. All of these above the 1.5 METs sedentary category classification. Sitting at a desk writing computer work station coding as common examples of sedentary waking behaviors populations.

The WHO definition is used as the reference definition used by the US Centers for Disease Control and Prevention, the UK four UK Chief Medical Officers physical activity guidelines 2019 update, the Australian Government Department of Health and Aged Care physical activity guidelines, Public Health England, and most other national public health agencies for their epidemiological sitting time surveillance population measurement definitions. National population-based surveys including NHANES and use survey self-report sitting time questions based on this definition.

WHO 2020 Global Action Plan on Physical Activity Target (GAPPA 2018-2030)

The WHO Global Action Plan on Physical Activity 2018-2030, known by the acronym GAPPA, was adopted by the Seventy-first World Health Assembly in May 2018 through Resolution WHA71.6. The plan's headline population-level insufficient activity target is a 15% relative reduction in the global age-standardized prevalence of insufficient physical activity among both adolescents and adults by the calendar year 2030. This target is a relative reduction target, meaning each WHO member state aims to reduce its own 2016 baseline national prevalence by fifteen percent relative its own baseline, rather than all countries converging to a single uniform absolute threshold. The 2016 baseline data is the year used for baseline. The 2016 baseline insufficient activity prevalence baseline data from WHO 2016 global prevalence data is globally approximately 23% of adults 18 years and older being insufficiently physically active per pooled global estimates. The GAPPA implementation framework is organized around four strategic objectives and twenty policy action areas: active societies creating awareness and systems, active environments creating walkable bikeable neighborhoods, active people programs interventions, active systems governance and multi-sector coordination mechanisms.

The GAPPA sedentary time component frames sedentary behavior as a complementary independent axis from physical activity participation. The WHO 2020 technical report classifies both insufficient moderate to vigorous physical activity participation and separately sedentary time on two separate axes. This means an individual accumulate sufficient MVPA minutes per week can still accumulate high daily sedentary hours, a pattern the 2020 framework describes as 'active couch potato phenotype. The 2020 framework explicitly states that replacing sedentary time with light intensity physical activity of any intensity duration, even below MVPA threshold ranges, produces measurable population-level benefits independent of total MVPA accumulated. GAPPA therefore includes both MVPA participation promotion actions and separately sedentary time reduction actions in the 20 policy areas.

WHO Adult Activity Guidelines

The WHO 2020 Global guidelines on physical activity and sedentary behaviour were released in Geneva November 2020 by the WHO Department of Noncommunicable Diseases Prevention. They represent the third iteration of the WHO global physical activity guidelines the first edition 2010 second edition 2010 and updated iteration updates include the 2020 edition first time including a dedicated sedentary behavior standalone chapter and formal guideline statements. For adults aged 18 through 64 years the following four-tier guideline structure. First guideline 1: All adults should undertake 150 to 300 minutes of moderate-intensity aerobic physical activity throughout the week, or undertake 75 to 150 minutes of vigorous-intensity aerobic physical activity throughout the week, or an equivalent combination of moderate-intensity and vigorous-intensity activity spread the week. Second guideline: For additional health benefits, adults may increase their moderate-intensity aerobic physical activity to beyond 300 minutes per week, or beyond 150 minutes per week of vigorous-intensity aerobic activity, or equivalent combinations beyond the minimum ranges. Third guideline: Adults should also perform muscle-strengthening activities that involve all major muscle groups on 2 or more days a week moderate or greater intensity muscle strengthening provides additional independent population-level beyond the aerobic component. Fourth guideline 4: All adults should limit the amount of time they spend being sedentary across the whole day, and replace sedentary time with physical activity of any intensity including light intensity below the moderate intensity threshold, in order to reduce population-level overall risk associations. Across all of these guideline statements are statements of population-level public health recommendation format.

Sedentary Break Pattern References

Sedentary break pattern references describe the timing duration frequency interrupting continuous prolonged sitting with short bouts physical activity. The 2022 Lancet Diabetes & Endocrinology paper Effect of frequent interruptions to prolonged sitting with light-intensity walking on postprandial glucose and insulin responses in adults with overweight and obesity is one of the most frequently cited in the sedentary interruption literature pattern. The study was a three-condition randomized crossover trial of adult participants with overweight or obesity status random three conditions in random order. The three conditions compared were: a continuous sitting condition without breaks, a condition with 2-minute light walking every 20 minutes, and a condition with 5-minute light walking every 30 minutes. The 5-minute bout every 30 minutes continuous sitting pattern is the one most commonly referenced in subsequent review articles and workplace wellness guideline summaries secondary sources citing the 2022 paper.

The 5 min break per hour standing reference pattern is a related practical office workday hourly pattern that translates the 30-minute pattern to the 5-minute every 30-minute pattern into a format that is easy to the 60-minute clock hour alignment that work schedules the hourly block. The pattern a single completed 60-minute clock hour contains 55 minutes of seated work plus 5 minutes of standing break or light ambulation break. Over a full 8-hour workday this 55/5 pattern accumulates 40 minutes total standing or light activity break time total, and 7 hours 20 minutes total seated work time total across the full 8 hour workday window. Alternative valid break schedules include 2 minutes every 20 minutes, 10 minutes every 2 hours, or other equivalent total break time accumulation per workday; the 55/5 per hour is one reference format among many possible implementations.

UK Biobank / NHANES Sitting Time Population Reference Hours

Population-representative sitting time hours reference data are available from multiple large-scale national surveillance programs. The US National Health and Nutrition Examination Survey (NHANES) 2015-2020 pooled data cycles published by the US National Center for Health Statistics within the Centers for Disease Control and Prevention document the CDC NCHS population sample the following approximate population the average daily total sitting the full US civilian non-institutionalized adult population 20 years and older approximately 6.4 hours per day sitting time self-reported measure. The NHANES sitting time question wording asks: "How much time do you usually spend sitting on a typical day?" response format in hours per day sitting. The occupational sitting component is the largest single component for working-age adults in the paid labor force.

The following table presents occupational group comparisons from pooled NHANES and Bureau of Labor Statistics American Time Use Survey sitting time data publications by broad occupational category for working-age adults 25 through 64 years currently employed. Values are approximate average daily total sitting time hours per typical workday only, combining occupational sitting time plus non-work sitting time.

The 8-10 hours sedentary average adult cited range is the commonly observed population range that the interquartile range the middle 50% of working-age adults in white-collar and professional occupational groups in high-income settings, combining occupational sitting time, commuting sitting time, and leisure sitting time (reading and viewing screen leisure together total 8 to 10-hour total sedentary time range the whole-day whole-day.

Daily Routine 24-Hour Block Sample Schedule

Daily routine 24-hour block sample scheduling is a time-use format breaks the 1440 minutes of a complete 24-hour calendar day into mutually exclusive and collectively exhaustive activity block categories. The block allocation method is the same reference format used by the US Bureau of Labor Statistics American Time Use Survey (ATUS) and similar national time-use survey methodologies. The following reference block allocation sample sums to exactly 24 hours total; alternative redistributions among block categories within the total 24-hour constraint remain valid as long as all block durations sum exactly 24 hours total.

Worked Planning Calculation: 8 Hour Workday Schedule

The following worked planning calculation applies the 5-minute break per hour standing reference pattern to a standard contiguous 8-hour workday window. The 5-minute per hour pattern divides each 60-minute clock hour into 55 minutes of seated desk work time and 5 minutes of standing or light activity break time, administered at any convenient point within each respective clock hour.

Break Accumulation Formula

Total standing break time across workday = minutes per break × hours in workday

Total standing break time across workday = 5 minutes/hour × 8 hours = 40 minutes standing breaks total

Total seated desk work time across workday = 8 hours × 60 minutes/hour − 40 minutes breaks = 440 minutes = 7 hours and 20 minutes seated desk work time
