ABSTRACT
This chapter examines sedentary behavior and its relationship to various health issues using the framework established by the Physical Activity Guidelines for Americans 2018 Advisory Committee Scientific Report (PAGA). An inverse relationship exists between the amount of moderate to vigorous physical activity and sedentary behavior when it comes to all-cause mortality. Individuals who were found to have greater than seven hours of sedentary behavior and also low levels of moderate to vigorous physical activity substantially increased their risk of all-cause mortality. The risk of mortality from cardiovascular disease and its relationship to sedentary behavior is very similar to the relationship between sedentary behavior and all-cause mortality. The PAGA 2018 Scientific Report judged the evidence between a direct relationship with the amount of time spent in sedentary behavior and higher mortality rates from cancer as limited. There is some evidence that moderate to vigorous physical activity lowers the risk of sedentary behavior.
