Too Much Sitting

In Brief Even when adults meet physical activity guidelines, sitting for prolonged periods can compromise metabolic health. Television (TV) time and objective measurement studies show deleterious associations, and breaking up sedentary time is beneficial. Sitting time, TV time, and time sitting in automobiles increase premature mortality risk. Further evidence from prospective studies, intervention trials, and population-based behavioral studies is required. Prolonged, unbroken sitting time is related adversely to cardio-metabolic health, and to premature all-cause and cardiovascular mortality.
