Article Snippet: Actical Mini-Mitter accelerometer , The Actical accelerometer (Mini Mitter) has an omnidirectional sensor and is capable of measuring movement in one plane. The sensor functions via a cantilevered rectangular piezoelectric bimorph plate and seismic mass, and it is capable of detecting movements in the 0.5 to 3 Hz range. Voltage generated by the sensor is amplified and filtered via analog circuitry. The amplified and filtered voltage is passed into an analog to digital converter, and the process is repeated 32 times per second (32 Hz). The resulting 1 s value is divided by four, then added to an accumulated activity value for the epoch. The Actical is the smallest accelerometer available (28 × 27 × 10 mm, 17 g) and is water resistant..

Article Snippet: Outcomes , The following instruments were used to measure outcomes relevant to this review at baseline, 3 months, and 6 months (end of intervention) Children's physical activity levels and sedentary behavior: omni‐directional Actical accelerometers (mini Mitter Co., Inc., Bend, Oregon, USA) worn during all waking hours for 7 days at each measurement time point; weekdays with at least 4 hours of accelerometer wear time between 8:30 am and 4:30 pm and at least 1 hour outside these hours were included, as were weekend days with at least 5 hours of wear time Data from the 3‐month assessment were not reported and could not be retrieved from the study authors. Available data from the end‐of‐intervention assessment included the following outcomes: total physical activity, MVPA, light physical activity, steps, and sedentary time Children's anthropometry: height measured with a portable stadiometer (Seca GmBH & Co Kg, Hamburg, Germany) and weight measured with a Tanita 300‐A scale (Tanita Corporation of America, Inc, Arlington Heights, Illinois, USA) Non‐standardized BMI values were reported for the end‐of intervention assessment. Sex‐ and age‐standardized BMI values were not reported and could not be retrieved. BMI data from 3‐month assessment were not available Prevalence of overweight or obesity was not reported for either assessment and could not be retrieved from the study authors , .
