Patterns of sedentary time and cardiometabolic risk among Canadian adults

Abstract

These findings in a large representative sample of Canadian adults indicate that breaking up sedentary time may be particularly important for cardiometabolic health.

Is objectively measured sitting at work associated with low-back pain? A cross sectional study in the DPhacto cohort

“…Our analyses indicated that EVA derivatives reflecting the temporal sitting pattern (ie, brief bursts, and moderate and prolonged periods) were not associated with LBP intensity. This stands in contrast to studies arguing that breaks from prolonged sitting are beneficial for health outcomes (49)(50)(51). However, breaks from sitting may increase the exposure to other risk factors for LBP, such as awkward working postures (6,52).…”

The emergence of sedentary behaviour physiology and its effects on the cardiometabolic profile in young and older adults

“…However, an increase in SB breaks was not associated with a decline in LDL-C. Conversely, a 0.21 mmol l −1 (CI 95 % −0.38-0.04) decline in LDL-C was associated with an hourly increase in MVPA (Carson et al 2014). As a result, reducing SB by increasing LIPA appears to be partly beneficial in the management of cholesterol and LPL.…”

Sedentary behaviour in rheumatoid arthritis: definition, measurement and implications for health

“…This move towards a more consistent thinking with regards to the modern conceptualisation of sedentariness is born out of recent findings demonstrating that SB holds deleterious consequences for health independently of any beneficial effects of physical activity engagement [4][5][6][7][8][9][10][11]. In particular, there is evidence that implicates SB as a precursor of heightened systemic inflammation in both healthy and clinical populations, irrespective of levels of the anti-inflammatory effect of physical activity [8][9][10][11].…”

“…In particular, there is evidence that implicates SB as a precursor of heightened systemic inflammation in both healthy and clinical populations, irrespective of levels of the anti-inflammatory effect of physical activity [8][9][10][11]. Indeed, there now exists a considerable amount of evidence demonstrating SB to be an independent risk factor for cardiovascular disease, the metabolic syndrome, sarcopenia and Type 2 diabetes, all of which have chronic systemic inflammation in common [9,10,[12][13][14][15][16]. These independent health effects may result from differences in the acute and chronic physiological responses to sedentary behaviour vs. physical activity engagement [17].…”

“…It is not only the total amount of sedentary time accumulated that may hold implications for health-related outcomes, but also the manner in which it is accumulated. Specifically, the number and [9,10,26], where more frequent sedentary breaks associate with beneficial changes to the levels of these biomarkers [8,9]. The importance of examining the contribution of specific behaviours to total sedentary time has also been underlined: certain sedentary behaviours, such as TV viewing, may be more detrimental to physical health than others [8].…”
