| Abstract | This study explored the validity of ActiGraph-determined sedentary time (<50cpm, <100cpm, <150cpm, <200cpm, <250cpm) compared with the activPAL in a free-living sample of bus drivers. 28 participants were recruited between November 2013 and February 2014. Participants wore an activPAL3 and ActiGraph GT3X+ concurrently for 7 days and completed a daily diary. Time spent sedentary during waking hours on workdays, non-workdays, during working-hours and non-working hours were compared between instruments. During working hours, all ActiGraph cut-points significantly underestimated sedentary time (p<0.05), whereas during non-working hours the <50 cpm cut-point demonstrated the closest agreement (ActiGraph sedentary time: 250±75 minutes vs activPAL sedentary time: 236±65 minutes). ROC analyses revealed that on workdays and non-workdays the ActiGraph cut-points exhibited relatively low sensitivity (all <0.62) and specificity (all <0.49) values. The use of the ActiGraph to measure sedentary time in this understudied, highly sedentary and at risk occupational group is not recommended. |
