Epidemiology
- 1/4 of U.S. adults sit > 8 hours/day[5]
- 3% of U.S. adults sit < 4 hours & exercise 150-300 minutes/week[5]
- 2007 to 2016, total daily sitting time increased by about an hour for adolescents (reaching 8 hours) & adults (6 hours) [6[
- leisure computer use of >= 1 hour per day increased for all age groups
- prevalence among adults increased from 29% to 50% from 2003 to 2016[6]
- > 50% of people watched >= 2 hours of television or videos daily[6]
Complications
- increased mortality for sedentary lifestyle
- increased risk of diabetes & cardiovascular disease[7]
- health hazards of sedentary behavior are not completely mitigated by exercise[2][4]
- > 12.5 hours daily in sedentary time & sedentary periods of > 30 minutes with greatest mortality risk
- predominantly sitting at work associated with 16% higher all cause mortality & 34% higher cardiovascular mortality
- increased risk of meningioma
- increased body mass index
- not associated with increased risk for dementia[7]
Management
- interrupting sedentary periods with activity every 30 minutes may mitigate mortality risk of sedentary lifestyle[4]
- additional 15-30 minutes of physical activity per day[9]
