The U.S. EPA Stochastic Human Exposure and Dose Simulation (SHEDS) model (U.S. EPA 2009a) can track activities minute by minute throughout the day and link these activities to environmental concentrations to estimate exposures by specific route and pathways (Zartarian et al. 2006).
Pamela explained that Kaiser's interventions include creating healthy environments inside schools and within communities, such as swelling activity minutes during physical education classes and time slots that children walk or bike to school.
Bedside minutes, patient interaction minutes, and educational activity minutes are presented as a percentage of total minutes on rounds in Table 4.
Finally, another study reported lower physical activity minutes than our study.
Differences between successful and unsuccessful participants with respect to self-monitoring of physical activity (minutes) approached significance (P = 0.059).
A physical activity score was calculated as the sum of the products of total time in each of the three categories of activity and the metabolic equivalent value (MET) assigned to each category [ 28, 29]: (walking minutes × 3.0 METs) + (moderate physical activity minutes × 4.0 METs) + (vigorous physical activity minutes × 7.5 METs), in accordance with the Compendium of Physical Activities [ 30].
Daily values for body weight, caloric intake, fat intake (g), and physical activity minutes were submitted at least weekly to the Rx Weight Loss website.
Note that the pre-diagnosis moderate and light intensity physical activity minutes per week were not included for one participant whose response was invalid.
The remainder of the randomization/program kickoff visit was used to teach skills for self-monitoring daily food intake, physical activity minutes, and body weight.
Vigorous activity (minutes per day) and walking (minutes per day) in the IPAQ correlated negatively with VO2peak, indicating that more minutes of both vigorous activity and walking was associated with a lower VO2peak.
3 First, we calculated the activity minutes score for each day (MPA minutes+VPA minutes×2) and then extrapolated the amount of physical activity using the following formula: Weekly physical activity=(5×mean workday activity score)+(2×mean day off activity score).
