Sedentary behaviors (SB) include sitting, reclining, or lying activities that are characterized by an energy expenditure of ≤1.5 metabolic equivalent ( Matthews et al., 2008 ; Owen, Healy, Matthews, & Dunstan, 2010 ; Pate, O’neill, & Lobelo, 2008 ; Tremblay et al., 2017 ). Older adults are the

Impact of Social Isolation on Physical Activity and Factors Associated With Sedentary Behavior in Older Adults During the COVID-19 Pandemic
Giovana Z. Mazo, Felipe Fank, Pedro S. Franco, Bruna da Silva Vieira Capanema, and Franciele da Silva Pereira
( Shahid et al., 2020 ). Social isolation due to the pandemic has led to changes in physical activity (PA) and sedentary behavior habits, which may increase the risk of mortality in older adults ( Hall, Laddu, Phillips, Lavie, & Arena, 2020 ). The World Health Organization classifies physical inactivity as
Sedentary Behavior, Physical Inactivity, and Metabolic Syndrome: Pilot Findings From the Rapid Assessment Disuse Index Study

In the United States, adults are sedentary approximately 8 hours daily during waking hours, based on accelerometry. 1 Sedentary behavior, which is defined as sitting or reclining during waking hours with an energy expenditure of ≤1.5 metabolic equivalent of task (MET), 2 has been linked to
Sedentary Behavior, Physical Activity, and Bone Health in Postmenopausal Women
Saori I. Braun, Youngdeok Kim, Amy E. Jetton, Minsoo Kang, and Don W. Morgan
The purpose of this study was to determine if bone health at the femoral neck (FN) and lumbar spine (LS) can be predicted from objectively-measured sedentary behavior and physical activity data in postmenopausal women. Waist-mounted ActiGraph GT1M and GT3X devices were used to quantify levels of sedentary and moderate-to-vigorous intensity behavior during a 7-day period in 44 older females. Bone health (normal and osteopenia/osteoporosis) of FN and LS was derived from T scores generated using dual energy x-ray absorptiometry. Binomial logistic regression analysis indicated that sedentary time and number of breaks in sedentary behavior were significant predictors of osteopenia/osteoporosis at the FN, but not at the LS. Adherence to physical activity guidelines was not a significant predictor of bone health at the FN or LS. Our findings suggest that more frequent interruptions in sedentary behavior are associated with improved bone health in postmenopausal women.

Leisure-Time Physical Activity Does not Attenuate the Association Between Occupational Sedentary Behavior and Obesity: Results From Alberta’s Tomorrow Project
Joshua A. Nicholas, Geraldine Lo Siou, Brigid M. Lynch, Paula J. Robson, Christine M. Friedenreich, and Ilona Csizmadi
Background:
Sedentary behavior has been proposed as a risk factor for obesity that is distinct from physical inactivity. This study aimed to examine the association between occupational sedentary behavior and obesity, and to determine if this association is independent of leisure-time physical activity (LTPA).
Methods:
Fully employed participants enrolled between 2001 and 2008 to Alberta’s Tomorrow Project, a prospective cohort study in Alberta, Canada, were studied (n = 12,409). Associations between occupational sedentary behavior and waist circumference (WC), waist-to-hip ratio (WHR), and body mass index (BMI) were examined using multiple binary and multinomial logistic regressions.
Results:
In men, a positive association was observed between daily occupational sedentary hours and WC, WHR, BMI, and with high risk profiles that incorporated both BMI and WC (P < .01). Controlling for vigorous-intensity LTPA in all models strengthened associations between sedentary behavior and measures of obesity. In contrast, inverse associations were observed for occupational sedentary hours and WHR for women (P < .05).
Conclusions:
In fully employed men, occupational sedentary behavior was positively associated with obesity risk that was not attenuated by physical activity. In women, an increase in obesity risk was not observed with sedentary behavior. Gender differences in the health effects of sedentary behavior require further study.
A Review of Sedentary Behavior Assessment in National Surveillance Systems
Danielle L. Harvey, Karen Milton, Andy P. Jones, and Andrew J. Atkin
During the last 2 decades, there has been a considerable increase in research assessing sedentary behavior and its potential links with health. 1 Sedentary behavior defined as “any waking behaviour characterised by an energy expenditure ≤1.5 METs while in a sitting or reclining posture” (p. 1), 2
Association of Family Functioning on Youth Physical Activity and Sedentary Behavior
Paul D. Loprinzi
Objective:
High family functioning is associated with reduced depression symptoms, better academic achievement, less disordered eating, and better metabolic control among youth. However, we know very little about the role of family functioning on physical activity and sedentary behavior among youth, which was the purpose of this study.
Methods:
Data from the 2003 and 2011–2012 cycles of the National Survey of Children’s Health were used. A total of 61,226 parents/guardians from the 2003 cycle and 40,446 parents/guardians from the 2011–2012 cycle (total n = 101,672) across all 50 states and the District of Columbia were examined. Parents answered questions related to family functioning and their child’s (age 6–17 yrs) physical activity and sedentary behavior.
Results:
Results were the same across both cycles; after adjustments, youth engaged in less physical activity if the family had worse family functioning (β = −0.06, P < .001). Similarly, youth engaged in more sedentary behavior if the family had worse family functioning (β = 0.05, P < .001).
Conclusion:
This research suggests that youth are more active and engage in less sedentary behavior if their family has greater family functioning.
Stability of Habitual Physical Activity and Sedentary Behavior Monitoring by Accelerometry in 6- to 8-Year-Olds
Laura Basterfield, Ashley J. Adamson, Mark S. Pearce, and John J. Reilly
Background:
Accelerometry is rapidly becoming the instrument of choice for measuring physical activity in children. However, as limited data exist on the minimum number of days accelerometry required to provide a reliable estimate of habitual physical activity, we aimed to quantify the number of days of recording required to estimate both habitual physical activity and habitual sedentary behavior in primary school children.
Methods:
We measured physical activity and sedentary behavior over 7 days in 291 6- to 8-year-olds using Actigraph accelerometers. Between-day intraclass reliability coefficients were calculated and averaged across all combinations of days.
Results:
Although reliability increased with time, 3 days of recording provided reliabilities for volume of activity, moderate-vigorous intensity activity, and sedentary behavior of 68%, 71%, and 73%, respectively.
Conclusions:
For our sample and setting, 3 days accelerometry provided reliable estimates of the main constructs of physical activity and sedentary behavior.
