ActProp_summary: Physical Activity Summary-Activity Proportions

In YukunZhang/PAactivPAL1.0: Summarize Daily Physical Activity from 'activPAL' Accelerometer Data

Description

Summarize sedantary, standing, and stepping activity measures

Usage

ActProp_summary(final_dat)

Arguments

final_dat

cleaned final data that is between record getup time and sleep time

Details

Proportion of sedentary/standing/stepping is the ratio of the total durations of sedentary/standing/step to the total worn time_

For number of steps, the number of stepping records multiplied by 2_ This is because every two steps lead to one row's record in the event files_

Number of interrupting sedentary behavior is approximated by the number of sedentary bouts_

Rate of interrupting sedentary behavior is the ratio of the daily number of interrupting sedentary behavior to total sedentary hours_

METs hours is the summation of METs hours from all activity records_

Value

perc_sedentary Proportion of sedentary

perc_stand Proportion of standing

perc_step Proportion of stepping

step_per_day Number of steps during the given period of time

break_per_day Number of interrupting sedentary behavior during the given period of time
