Background: Physical activity (PA) has acquired a significant relevance due to the health benefits associated with its
practice. Accelerometers are an effective tool to assess PA; however, the diversity of cut-off points used to define different
PA intensities through accelerometry could interfere in the interpretation of the findings among studies.
Objectives: The present study aimed to examine the sedentary behavior (SB) and physical activity (PA) levels in children
using six selected accelerometry protocols based on diverse cut-off points.
Methods: Clinical examination, anthropometric measurements, and PA evaluation by accelerometry were assessed
in 543 selected children (10 ± 2.4 years old) from the Spanish GENOBOX study. The ActiLife data scoring program was
used to determine daily min spent in SB, and light, moderate, vigorous and moderate-vigorous PA using six validated
accelerometry protocols differing in their cut-off points.
Results: Very different estimations for SB and PA intensity levels were found in children, independently of the nonwear-
time algorithm selected, and considering puberty stages, age and body mass index. The time spent in daily SB
varied from 471 to 663.7 min, PA ranged from 141 to 301.6 min, and the moderate-vigorous PA was reported between
20.7 and 180.2 min.
Conclusion: The choice of a particular accelerometry protocol considering these factors is important to evaluate
SB or PA intensities to suit the characteristics of the sample researched. It seems necessary to establish future lines of
research that include different analytical approaches to measure SB and PA by accelerometry based on standardized
and validated methodology.
