Document Summary
Sedentary behavior: prolonged periods of being physically inactive, typically involving sitting in different contexts and for different purposes. Cross-sectional study: a study measuring different attributes at the same time and examining whether they are significantly related to each other. Such studies cannot identify causation, but they generate hypotheses that can be tested more rigorously in prospective epidemiological or experimental studies.

The nature of the relationships of sedentary behavior with risk biomarkers and related health outcomes needs to be identified.

The contextual determinants of sedentary behavior need to be identified in domestic, workplace, transportation, and recreation contexts.
