“…This may be particularly true for the generic sitting time measure. However, previous ALSWH analyses have shown associations between this sitting measure with body weight, breathing difficulty and chest pain, and mortality, 15,17,33 and other studies have demonstrated relationships with mortality using similar generic measures. 16 Notwithstanding, misclassification may have resulted in underestimation of the true effect of sitting time on health-related costs.…”

Background: Physical inactivity and prolonged sitting are associated with negative health outcomes. Purpose:To examine the health-related costs of prolonged sitting and inactivity in middleaged women.Methods: Australian Longitudinal Study on Women's Health participants (born 1946−1951) answered questions about time spent sitting, walking, and in moderate and vigorous leisure activities in 2001 (n=6108), 2004 (n=5902), 2007 (n=5754) and 2010 (n=5535) surveys.Sitting time was categorized as low (0−4), moderate (5−7), and high (≥8 hours/day). Physical activity was categorized as inactive (<40), low (40−600), moderate (600−1200) and high (≥1200 metabolic equivalent minutes/week). National health insurance claims data averaged over the survey year ±1 year were used to calculate annual costs (Australian Dollars [AU$]).Differences between categories in median costs were estimated using quantile regression over four surveys with bootstrapped 95% CIs. Analyses were performed in 2013. Results:In 2010, annual median costs were AU$689 (interquartile range [IQR]=274, 1541) in highly active participants, AU$741 (IQR=279, 1690) in inactive participants, AU$671 (IQR=273, 1551) in participants with low sitting time, and AU$709 (IQR=283−1575) in participants with high sitting time. The difference in median costs for inactive and highly active participants was AU$94 (CI=57, 131) after adjustment for confounders. No statistically significant associations were found between sitting time and costs. When sitting and physical activity were combined, high sitting time did not add to the inactivity-associated increased costs. Associations were consistent across normal weight, overweight, and obese subgroups. Conclusions:Physical inactivity, but not prolonged sitting, was associated with higher health-related costs in middle-aged women. 3 IntroductionPhysical inactivity is associated with numerous physical and mental health conditions and accounts for approximately 1.5%−3.0% of the total direct health care costs in developed countries.1 It is estimated that a 10% reduction in the prevalence of inactivity could potentially reduce health care expenditures by 96 million Australian Dollars (AU$) and 150 million Canadian Dollars per year in Australia and Canada (equating to 99 and 129 million U.S. Dollars, respectively). 2, 3 Despite the potential health and economic benefits, only about half the population in developed countries meet the recommended levels of physical activity. [4][5][6] In addition to inactivity, prolonged sitting is thought to be associated with negative health outcomes such as weight gain and increased risk of mortality. 7 However, the economic consequences of prolonged sitting remain unknown. Moreover, as some studies have reported interaction effects of physical activity and sedentary time in association with mortality, 8, 9 the combined effects of prolonged sitting and inactivity on direct health care costs may be more important than their individual effects.A previous study by our group found an interaction with BM...

“…Three studies found that people who spent more time watching television and/or using the computer had a greater likelihood of having mental disorders (de Wit, van Straten, Lamers, Cuijpers, & Penninx, 2011;Peeters et al, 2012;Sanchez-Villegas et al, 2008), and two studies found that people that spent more time engaging in television, computer, and/or screen-based entertainment behaviours tended to have more psychological distress (Hamer et al, 2010) and worse mental wellbeing (Atkin, Bull, & Biddle, 2012). This previous research is limited in that it remains unclear if the link to mental health is with the overall time spent sitting or the time spent in a specific context (i.e., television-watching, using the computer, screen-based entertainment).…”

Spending a lot of time sitting has been linked to more depressive symptoms and spending a lot of time engaged in screen-based sitting has been linked to greater likelihood of having mental disorders and poorer psychological distress. The purpose of this study was to examine whether overall sitting time and time spent sitting in different contexts was associated with depression, anxiety, or stress symptoms. Sitting time (time spent sitting on typical work-and non-work days while engaged in leisure activities, working, using a computer, watching television, and in transport) and symptom severity of depression, anxiety and stress were self-reported in a cross-sectional online survey in 2012 by Australian adults (N=1,104, 55% female, M age=58 years). Associations were examined using negative binomial regression analyses accounting for the covariates of physical activity, sex, age, income, education, and presence of chronic conditions. Overall sitting time was significantly associated with more severe depression (b=0.01, 95% CI= 0.00 -0.02) and anxiety (b=0.03, 95% CI= 0.02 -0.04) but not stress (b=0.01, 95% CI= -0.00 -0.02) symptoms. Time spent sitting while at a computer was associated with more severe depression (b=0.04, 95% CI= 0.01 -0.07) and anxiety (b=0.03, 95% CI= 0.00 -0.06) symptoms, and time spent sitting while in transport was associated with more severe anxiety (b=0.09, 95% CI= 0.05 -0.13) and stress (b=0.05, 95% CI= 0.02 -0.08) symptoms. Limiting overall sitting time and time spent sitting while at a computer or in transport could be a potential strategy to improve mental health. Evidence is emerging that more sitting time is associated with depressive symptoms or likelihood of having mental disorders (Arredondo et al., 2013; Balboa-Castillo, León-Muñoz, Graciani, Rodríguez-Artalejo, & Guallar-Castillón, 2011;Hamer, Stamatakis, & Mishra, 2010;Peeters, Burton, & Brown, 2012;Sanchez-Villegas et al., 2008;Teychenne, Ball, & Salmon, 2010a, 2010bvan Uffelen et al., 2013), but no studies have tested how sitting time is related to anxiety or stress symptoms. Anxiety and stress are important aspects of mental health to investigate, given that more than 75% of people report experiencing some stress or anxiety symptoms (Crawford & Henry, 2003), and between 5-10% of the population in developed countries have severe depression, anxiety, and stress-related disorders (Demyttenare et al., 2004). Even mild symptoms of anxiety and stress can be highly debilitating and contribute considerably to burden of disease (S. Cohen & Williamson, 1991; Kalia, 2002; Kiecolt-Glaser, McGuire, Robles, & Glaser, 2002; Pietrzak et al., 2012;Rai et al., 2012), so it is important to determine whether sitting time is linked to anxiety and stress, as well as to depression symptoms. These studies suggest that more time spent sitting overall (i.e., across multiple sitting activities) is associated with more severe depressive symptoms; however it remains unclear whether overall sitting time is associated with severity of anxiety or s...

The studies presented in this thesis highlight important issues relating to the measurement of physical activity (PA) and sedentary behaviour (SB) in older adults, especially relating to the transfer of these methods to free-living environments.Study One examined cut-points for ActiGraph GT3X+ (AG) for estimating time spent in SB in older adults in free-living environments. ActivPAL 3 ™ (AP) was used as the reference standard.Movement patterns were measured in 41 older adults over seven consecutive days with both AG and AP. The results suggested that different cut-points must be used in older adults. In the case of older adults when using 1-minute epochs, for example, 25 counts/minute must be considered when using the AG vertical axis only, or 200 counts/minute when using the three axes of the accelerometer. different activities were assessed. It was concluded that when selecting an equation to estimate total daily EE from accelerometer data, equations with more accurate estimates of sedentary behaviour might be preferred. However, when the main interest is to estimate total time spent in different physical activity levels, a method with higher agreement for categorising activities may be preferred. Study Two ConclusionThe work contained in this thesis will help researchers to 1) implement more accurate tools in the surveillance of PA and SB in larger studies, 2) better understand the strengths and limitations of current predictive methods when applying them in free-living environments, and 3) improve interpretation and translation of energy expenditure measures in older adults.
