Studies that did not directly measure sedentary behavior often have been used to draw conclusions about the health effects of sedentariness. Future claims about the effects of sedentary, light, and moderate-to-vigorous activities on health outcomes should be supported by data from studies in which all levels of physical activity are differentiated clearly and measured independently.

    • "Sedentary behaviours, defined as activities with low levels of energy expenditure (Pate et al., 2008), are highly prevalent in children and adolescents (Foley et al., 2011; Pate et al., 2011; Basterfield et al., 2011). A common form of sedentary behaviour among children is screen viewing (SV), (e.g. "

    ABSTRACT: Background: Child screen viewing (SV) is positively associated with poor health indicators. Interventions addressing rule-based parenting practices may offer an effective means of limiting SV. This study examined associations between rule-based parenting practices (limit and collaborative rule setting) and SV in 6-8-year old children. Methods: An online survey of 735 mothers in 2011 assessed: time that children spent engaged in SV activities; and the use of limit and collaborative rule setting. Logistic regression was used to examine the extent to which limit and collaborative rule setting were associated with SV behaviours. Results: 'Always' setting limits was associated with more TV viewing, computer, smartphone and game-console use and a positive association was found between 'always' setting limits for game-console use and multi-SV (in girls). Associations were stronger in mothers of girls compared to mothers of boys. 'Sometimes' setting limits was associated with more TV viewing. There was no association between 'sometimes' setting limits and computer, game-console or smartphone use. There was a negative association between collaborative rule setting and game-console use in boys. Conclusions: Limit setting is associated with greater SV. Collaborative rule setting may be effective for managing boys' game-console use. More research is needed to understand rule-based parenting practices.

    • "can we prevent sedentary behavior in people with binge eating disorder? Sedentary behavior refers to activities that do not increase energy expenditure substantially above the resting level and includes activities such as sleeping, sitting, lying down, watching television, and other forms of screen-based entertainment (Pate, O'Neill, & Lobelo, 2008). There is a growing body of evidence in the general population that sedentary behavior may, even independent of physical activity, be a distinct risk factor for multiple adverse health outcomes. "

    ABSTRACT: Despite emerging evidence illustrating the benefits of physical activity for people with binge eating disorder, engaging this population in physical activity is challenging. The International Organization of Physical Therapists in Mental Health (IOPTMH) set out to summarize, appraise, and strengthen the direction of physical activity endeavors. This process led to the identification of 10 important research questions which are discussed. Addressing these 10 research questions is critical for developing evidence-based approaches for promoting and sustaining an active lifestyle in people with binge eating disorder.

Secondary prevention guidelines recommend cardiac patients accumulate ∼150 minutes of moderate to vigorous PA (i.e., MVPA > 3.0 METs) each week in bouts of >10 minutes (American College of Sports Medicine, 2010; Garber et al., 2011; Smith et al., 2001).

    ABSTRACT: Background: Sedentary behaviour and the level of daily physical activity are of particular concern in cardiac patients, as diminished activity may be a strong predictor of mortality in this population. Purpose: In this study we assessed sedentary behaviour and the quantity and quality of daily physical activity among older cardiac patients who were at different stages of recovery following a cardiac event. Design: We used a cross-sectional design and a convenience sampling technique. Method: Participants were recruited into three groups: an Acute group (n = 32), a Rehab group (n = 32), and a Maintain group (n = 29). Continuous minute by minute physical activity was assessed using the SenseWear Mini Armband, which was worn throughout each day for four consecutive days and provided data on steps/day, as well as time spent sedentary (waking time ≤ 1.5 METs), or in light (1.6-2.9 METs) or moderate-vigorous (≥ 3.0 METs) physical activity. Findings: While the Rehab group accumulated more daily activity than the other two groups, they remained sedentary for approximately 70% of waking time. The quantity and quality of the activity in the Maintain group was comparable to that observed in the Acute group. Conclusions: Our observation of consistently elevated sedentary time regardless of whether the participant was entering, completing or were long removed from a formal cardiac rehabilitation program reinforces the need for cardiac rehabilitation nurse educators to both monitor routine daily activity and encourage coronary artery disease patients to adapt a lifestyle that is focused on reducing sedentary behaviour by incorporating planned exercise training and unstructured physical activity throughout the day.
