Bouts and breaks in children's sedentary time: currently used operational definitions and recommendations for future research

摘要

Increasing attention is paid to the potential health effects of children's sedentary bouts and breaks, rather than total sedentary time. This paper discusses currently used operational definitions of sedentary bouts and breaks in studies among children. Remarkably, these studies applied different operational definitions, complicating comparison between studies. To advance the field of sedentary behaviour epidemiology, we need a clear and evidence-based operationalization for such sedentary bouts and breaks.
