compute_pro_actigraph_score {activAnalyzer}

Compute PROactive monitor-based physical activity score for C-PPAC tool

Description

This function computes the PROactive activity score based on the daily median or mean of step count or vector magnitude unit (in counts/min) obtained using an ActiGraph accelerometer.

Usage

compute_pro_actigraph_score(
  x,
  quest = c("C-PPAC", "D-PPAC"),
  metric = c("steps", "vmu"),
  fun = c("median", "mean")
)

Arguments

x

A numeric value that should be the daily median or the daily mean of step count or vector magnitude unit following a measurement of physical activity; see Gimeno-Santos et al. (2015, online supplement, p.71, doi: 10.1183/09031936.00183014) and Garcia-Aymerich et al. (2021, supplemental material, p.17; doi: 10.1136/thoraxjnl-2020-214554).

quest

A character value to indicate for which PROactive questionnaire a score of the amount of physical activity should be computed.

metric

A character value to indicate the metric for which the PROactive score should be obtained.

fun

A character value to indicate if the metric used in the function is the median or the mean of the results obtained each day of the measurement.

Value

A numeric value.

Examples

compute_pro_actigraph_score(x = 3500, quest = "C-PPAC", metric = "steps", fun = "median")

compute_pro_actigraph_score(x = 340, quest = "C-PPAC", metric = "vmu",  fun = "mean")
