“…However, a previous report on the same cohort, with six years follow-up, showed only small changes in physical activity composition. 39 No data on sleep were obtained, and consequently, the accelerometer captured data represent the composition of awake time and not for all 24 hours of a given day. There are also limitations associated with the data collection method.…”

The association between the composition of movement behaviors and mortality risk, acknowledging the composition nature of daily time data, is limited explored. The aim was to investigate how the composition of time spent in sedentary behaviors (SB), light intensity physical activity (LIPA), and moderate‐to‐vigorous physical activity (MVPA) is associated with all‐cause mortality, in a cohort with 15 years follow‐up time, using compositional data analysis. Eight hundred fifty‐one participants (56% women, mean age 53 years) provided objectively assessed physical activity data using an ActiGraph accelerometer and were followed for 15 years. Association of daily time composition of movement behaviors with risk of mortality was explored using compositional data analysis and hazard ratios (HR) of mortality were estimated based on a cox regression model. A significant (P < .001) positive association between time spent in SB relative to time in other behaviors and a significant (P = .018) negative association between time spent in LIPA relative to time in other behaviors, with all‐cause mortality, were found. Substituting time spent in LIPA or MVPA with time in SB increased the hazard for all‐cause mortality, with greater effect found for MVPA (20 minutes replacement; HR 1.26, 95% CI 1.04‐1.52) than for LIPA (20 minutes replacement; HR 1.06, 95% CI 0.65‐1.73). In a public health perspective, it is recommended to substitute SB with either LIPA or MVPA, but for individuals with little time spent in MVPA, the most important message may be to try to maintain that behavior.

“…Having said that, the ABC study was conducted earlier (in 2001–2002), using an older model accelerometer (ActiGraph 7164) and had a different wear site (the lower back), while the SNAP study was more comparable to the other studies in this respect. However, a sub-sample of the ABC study were followed-up in 2007–2008 (500 participants) and although sedentary time had increased by half an hour per day, the overall results were similar [32]. Even though studies have shown that there are no significant differences between accelerometer placement on the hip or lower back [33], there is some discussion about the comparability of the results of the two ActiGraph models [34–36].…”

ObjectiveThe objective of this study was to pool, harmonise and re-analyse national accelerometer data from adults in four European countries in order to describe population levels of sedentary time and physical inactivity.MethodsFive cross-sectional studies were included from England, Portugal, Norway and Sweden. ActiGraph accelerometer count data were centrally processed using the same algorithms. Multivariable logistic regression analyses were conducted to study the associations of sedentary time and physical inactivity with sex, age, weight status and educational level, in both the pooled sample and the separate study samples.ResultsData from 9509 participants were used. On average, participants were sedentary for 530 min/day, and accumulated 36 min/day of moderate to vigorous intensity physical activity. Twenty-three percent accumulated more than 10 h of sedentary time/day, and 72% did not meet the physical activity recommendations. Nine percent of all participants were classified as high sedentary and low active. Participants from Norway showed the highest levels of sedentary time, while participants from England were the least physically active. Age and weight status were positively associated with sedentary time and not meeting the physical activity recommendations. Men and higher-educated people were more likely to be highly sedentary, while women and lower-educated people were more likely to be inactive.ConclusionsWe found high levels of sedentary time and physical inactivity in four European countries. Older people and obese people were most likely to display these behaviours and thus deserve special attention in interventions and policy planning. In order to monitor these behaviours, accelerometer-based cross-European surveillance is recommended.Electronic supplementary materialThe online version of this article (doi:10.1007/s40279-016-0658-y) contains supplementary material, which is available to authorized users.

“…The women in our study are, compared with a Swedish sample of 1172 participants (54% women, mean age 45, 10% obese) measured longitudinally by the GT1M accelerometer between 2001 and 2008 (210) , more physically active and spend less time sedentary. In the study In accordance with our results, previous research has failed to detect a significant change in PA from pre-to post-surgery among patients undergoing RYGB when PA is measured objectively (127) .…”
