“…These findings again provide insight into the important role of social support in this community. A growing body of evidence indicates that shorter-duration and more frequent sedentary breaks have important health benefits [ 23 - 25 ]. While social support may be a facilitator of walking, it may inadvertently offset the positive effects of a built environment that is more supportive of a healthy balance between active living and sedentary time.…”

“…Intensity was measured using cut points established by Kozey Keadle et al [ 22 ]. We distinguished between the duration of time of sedentary breaks and the total number of breaks due to a growing body of literature distinguishing the health effects of the frequency of breaks from those of the overall time spent in sedentary activity [ 23 - 25 ]. To adjust for significant skewness, we performed natural logarithm on each of these outcome variables.…”

ObjectivesTo determine the relationships between physical activity (PA), the neighborhood environment support for PA, and social support for PA among Mexican-American women living in South Texas. The Enlace study was a randomized controlled trial that tested the effectiveness of a promotora-led PA intervention among low-income Mexican origin women (n=614) living in colonias.MethodsThe dependent measures included accelerometer-measured average moderate to vigorous physical activity (MVPA) and sedentary breaks and the Community Health Activities Model Program for Seniors PA 41-item questionnaire. The independent measures included the Physical Activity and Neighborhood Environment Scale (PANES) and the 13-item Physical Activity Social Support (PASS) scale.ResultsEnlace participants were on average 40.4 (standard deviation, 10.3) years old, born in Mexico (86.1%), and uninsured (83.1%). Adjusted linear regression results indicated that each 1-point increment in the PANES overall score was associated with 0.050 (p<0.001) unit increase in sedentary break and a −0.043 (p=0.001) unit decrease in sedentary break duration. Both PANES (β=0.296; p=0.002) and PASS scores (β=0.076; p<0.001) were associated with weekly average self-reported MVPA. Interaction effects were observed between PASS scores and accelerometer-measured frequency of sedentary breaks and sedentary time duration.ConclusionsThe findings of this study indicate that the relationships between PA and built environment and social support are measure-dependent and suggest that reducing sedentary time in this population may require a closer assessment of social support for PA.

What is the effect of interrupting prolonged sitting with frequent bouts of physical activity or standing on first or recurrent stroke risk factors? A scoping review

et al. 2019

The objective of this review was to ascertain the scope of the available literature on the effects of interrupting prolonged sitting time with frequent bouts of physical activity or standing on stroke and recurrent stroke risk factors. Databases Medline, Embase, AMED, CINAHL and Cochrane library were comprehensively searched from inception until 21 st February 2018. Experimental trials which interrupted sitting time with frequent bouts of physical activity or standing in adults (≥ 18 years) were included. Comparison to a bout of prolonged sitting and a measure of at least one first or recurrent stroke risk factor was required to be included. Overall, 30 trials (35 articles) were identified to meet the inclusion criteria. Fifteen trials were completed in participants at an increased risk of having a first stroke and one trial in participants at risk of a recurrent stroke. Outcomes of hypertension and dysglycemia were found to be more favourable following predominately light- to moderate-intensity bouts of physical activity or standing compared to sitting in the majority of trials in participants at risk of having a first stroke. In the one trial of stroke survivors, only outcomes of hypertension were significantly improved. These findings are of significant importance taking into consideration hypertension is the leading risk factor for first and recurrent stroke. However, trials primarily focused on measuring outcomes of dysglycemia and without assessing a dose-response effect. Additional research is required on the dose-response effect of interrupting sitting with frequent bouts of physical activity or standing on first and recurrent stroke risk factors, in those high risk population groups.

“…Breaking up prolonged sitting is associated with a significantly improved metabolic profile (Chastin et al, 2015 ), reduced self-reported fatigue (Wennberg et al, 2016 ), and reduced all-cause mortality risk (Katzmarzyk, 2014 ). Additionally, regularly breaking up prolonged sitting with short (1 min 40 s) bouts of walking (light-intensity physical activity) (Peddie et al, 2013 ) or standing (Benatti et al, 2017 ) is more effective than a single continuous (30 min) bout of MVPA per day in lowering postprandial glucose and insulin concentrations in healthy, normal weight adults.…”

Improving Cardiometabolic Health with Diet, Physical Activity, and Breaking Up Sitting: What about Sleep?

et al. 2017

View full text Add to dashboard Cite

Cardiometabolic disease poses a serious health and economic burden worldwide and its prevalence is predicted to increase. Prolonged sitting, lack of physical activity, poor diet, and short sleep duration are ubiquitous behaviors in modern society, and all are independent risk factors in the development of cardiometabolic disease. Existing evidence demonstrates that breaking up prolonged periods of sitting is beneficial for cardiometabolic health, however, studies have not controlled for prior sleep duration. This article examines how prolonged sitting and short sleep duration independently contribute to cardiometabolic risk, and how breaking up sitting and obtaining adequate sleep may reduce this risk. We suggest that as prolonged sitting and short sleep duration influence the same cardiometabolic parameters, there is potential for short sleep to attenuate the positive impact of breaking up prolonged sitting with physical activity. Likewise, breaking up prolonged sitting and obtaining adequate sleep together could improve predictors of cardiometabolic disease, i.e., the combined effect may be stronger than either alone. To explore these perspectives, we propose a research agenda to investigate the relationship between breaking up prolonged sitting with physical activity and short sleep duration. This will provide an evidence-base for informing the design of interventions to reduce the burden of cardiometabolic disease on communities worldwide.

Intermittent Standing but not a Moderate Exercise Bout Reduces Postprandial Glycemia

Abstract: Breaking up prolonged sitting with nonambulatory standing across 9 h acutely reduced postprandial glycemic response during and the day after the intervention independent of insulin levels, whereas a 30-min MVPA bout did not.
