- W2468553958 abstract "Introduction : The use of accelerometers and pedometers are objective methods to measure physical activity in preschoolers (1). However, accelerometers are expensive and the units of measurement (counts) have less intuitive utility compared to pedometer step counts. Pedometers are less costly and can be used in large-scale studies. Nonetheless, most pedometer models only provide the total steps per day and preschoolers can easily reset these devices. The Omron Walking Style Pro pedometer advances older types as it holds a memory of the step counts, it provides an hourly summary of the steps taken and makes it feasible to determine the most active moment of the day. We aimed at validating this type of pedometer against the ActiGraph accelerometer (2).Methods : A sample of 46 preschool children (4-6 yrs) wore an ActiGraph GT1M accelerometer and an Omron Walking Style Pro pedometer simultaneously for four consecutive days. Hourly step counts were compared. The study was conducted in May 2011.Results : Analysis between hourly step counts from both devices revealed a high correlation (r = 0.95, p<0.001). An ICC value of 0.971 was found, which disclosed a high reliability between the accelerometer and pedometer. Repeated Measures ANOVA showed no significant differences at the 0.001 level (3). After conducting a Bland-Altman plot, additional evidence was provided that there were no significant differences between the step counts obtained from both devices.Discussion and conclusion : The Omron Walking Style Pro pedometer is a valid instrument to measure physical activity in preschool children. Because of the relatively low cost, this device could be used in large-scale studies. This pedometer is only limited in recording detailed information on the intensity of the physical activity.
