“…Fifteen studies measured hPA exposure using accelerometers [ 28 , 30 , 31 , 33 , 36 , 37 , 44 , 45 , 47 , 49 , 51 – 55 ], and 16 measured hPA via self-report questionnaire or interview [ 27 , 30 , 34 – 36 , 38 – 40 , 42 , 43 , 46 , 48 , 50 , 56 – 58 ]. Two studies [ 30 , 36 ] utilised both self-report and accelerometer to measure hPA reporting results separately.…”
