Another issue that arises when using ordinal scales of occupational physical activity (job title-based or self-reported) in a sedentary behaviour context is the selection of the appropriate referent category.
Regarding the context of sedentary behaviour, it appeared that computer and internet use contributed largely to the total sedentary time of both boys and girls (weekday: 4.65 h/d, 4.08 h/d; weekend: 7.09 h/d, 6.41 h/d).
We examined whether street layout —a key urban design element— is associated with walking and sedentary behaviors in the context of a non-Western country; and, whether such associations differ between an urban and a rural area.
Nevertheless, in contrast to previous evidence, 4 5 8 9 the associations between context specific sedentary time (TV viewing) and psychological distress were far less consistent.
This explorative study takes a step in providing insight into the understanding of sedentary behaviours and the context in which these behaviours take place.
Given that subjective mental state is a complex measure comprising cognitive (depressed mood) and somatic symptoms (eg, lethargy, tiredness, lack of appetite and pain), this might partly influence an individual's assessment of context specific sedentary time.
The main advantage of this device in the context of sedentary research is that it employs postural allocation rather than inherently limited methods that use time outside specified count thresholds.
However there is currently a lack of detailed information on the different types of sedentary behaviour and the context in which this takes place [ 5], sedentary behaviour being assessed in most previous studies by time spent sitting overall or time spent watching television [ 6].
The office may offer a platform for activity promotion and reductions in sitting time (one domain of sedentary behaviour), but research in this context is relatively limited.
In contrast, if the associations were only observed for self-reported sedentary time, this might reflect a context-specific effect or reporting bias.
