Abstract: Background: Objective methods need to replace subjective methods for accurate\nquantification of physical activity. To be used in clinical settings objective methods\nhave to show high reliability, validity and feasibility. The commonly used activity\nmonitors are unable to detect the variety of physical activities. Multisensor activity\nmonitors have larger potential for a more accurate quantification of physical activity.\nChildren who have undergone surgery for congenital heart defects have the possibility\nto a physical active lifestyle because of the progress in cardiac surgery and cardiology.\nAims: To evaluate the ability of the multisensor activity monitors ActiReg, SenseWear\nArmband and IDEEA to assess physical activity and energy expenditure (I-IV), and to\nassess physical activity, sports participation and aerobic fitness in children who have\nundergone surgery for congenital heart defects (V).\nMethods: I) Patients with chronic obstructive pulmonary disease (COPD) wore the\nActiReg during 7 days with doubly labelled water as criterion for energy expenditure;\nII-III) 11-13 years old children performed different physical activities while wearing\nthe ActiReg, SenseWear Armband and IDEEA with indirect calorimetry as criterion\nfor energy expenditure; IV) a new ActiReg algorithm calibrated in 11-13 years old\nchildren was tested in 14-15 years old children wearing the ActiReg but also the\nSenseWear Armband during 14 days using doubly labelled water as criterion for\nenergy expenditure; V) children who have undergone surgery for congenital heart\ndefects and healthy controls in the age-groups 9-11 and 14-16 years wore the ActiReg\nduring 7 days, were interviewed about sports participation and performed a maximal\nexercise test with measured oxygen uptake for the assessment of aerobic fitness.\nResults: I) The ActiReg showed a mean (sd) accuracy of 99 (10) % in assessing\nenergy expenditure in COPD patients; II-III) the accuracy of the SenseWear Armband\nand IDEEA in assessing energy expenditure varied between the different activities but\nshowed an overall value of 81 (11) %/85 (8) % for the SenseWear Armband and 96\n(10) % for the IDEEA; the SenseWear Armband showed increased underestimation\nwith increasing intensity; the ActiReg algorithm overestimated moderate physical\nactivity and the ActiReg had a limitation in registering vigorous physical activity; IV)\nthe accuracy of the ActiReg with the new algorithm and the SenseWear Armband was\n99 (11) % and 96 (10) %, both with increased underestimation with increasing\nintensity; V) children who have undergone surgery for congenital heart defects showed\nsimilar physical activity as the healthy controls but a tendency to lower amount of\nsports participation; in the older children, especially in boys, the patients had lower\naerobic fitness; still, their amount of sports participation was considered high and their\naerobic fitness moderate.\nConclusions: The ActiReg, SenseWear Armband and IDEEA have to be improved to\nbecome accurate instruments in clinical settings. While children who have undergone\nsurgery for congenital heart defects had a physical activity level comparable to healthy\nchildren, some of them may require support for their engagement in exercise and\nvigorous physical activity.
