Questions related to Physical Activity Epidemiology
Prolonged sitting has been increasingly recognized as a serious issue in public health. However, the cut-off point above which health is impaired in general population is still equivocal. Are there any quantitative guidelines on sitting? Especially it provides suggestions about a cut-off or threshold of daily sedentary time for adults or older people?
Disabled people are considered under WHO recommandations for daily physical activity, but standard measures used for healthy people could them really be used at the same for disabled ?
In other way, for example, for a femoral amputee, walking at 4m/s speed is it under 3 MET (very low level activity) or over (low activity)?
I have run an analysis with melogit in STATA, but I´m having troubles interpretating the output.
The multilevel multivariate logistic regression gives me the following output:
region OR STD ER 95% CI
var(_cons)| .012162 .0134205 .0013987 .1057516
LR test vs. logistic regression: chibar2(01) = 1.52 Prob>=chibar2 = 0.1087
Do you know what type of intervention is best to promote physical activity in different population? Does anyone use a particular theory?
They suggest that journals formally define sedentary behaviour as "any waking behaviour characterized by an energy expenditure ≤1.5 METs while in a sitting or reclining posture.". They also suggest that journals should use the term "inactive" to describe those who are performing insufficient amounts of moderate to vigorous intensity physical activity (i.e., not meeting specified physical activity guidelines).
If I have a RCT where I have a control group (receiving funny data messages) and an intervention group (diet, physical activity tips reinforced with self-efficacy) with the aim of improving glycemic control.
I measured physical activity (PA) with an accelerometer. And I want to know the pros and cons of using my PA data as continuous and as a categorical variable.
Thank you for your help and time.
There are well documented examples in medicine such as the use of steroids in premature deliveries, prescription of streptokinase and more recently statins and tamiflu have had significant shifts in perceived benefits due to systematic reviews. The use of pre-exercise static stretching comes to mind, although this is also an example of how long applied practice can take to change. Any other areas would be more than welcome.
