Health consequences of sedentary behavior have emerged as a new focus for research on physical activity and health.
Sedentary time includes time spent for TV viewing, computer and game-console use, workplace sitting, sitting in automobiles and sitting during commuting in the workplace, domestic environment, and during leisure time.
The research addressing adults shows an increased risk of type 2 diabetes,
cardiovascular disease and obesity. For school-aged youth, excessive weight gain, poor fitness levels, adverse psychosocial outcomes, and decreased academic achievement were shown. Recent studies from Canada, Australia, and the United States, show prospective relationships of sedentary behaviors with premature mortality.
Research findings show that breaking up sedentary time can be beneficial for reducing the adverse effects of sedentary behaviour. Having a higher number of breaks in sedentary time is beneficially associated with waist circumference, body mass index, triglycerides, and 2-h plasma glucose. It is also shown to have beneficial association with metabolic biomarkers.
Sedentary behaviour like TV-viewing habits during childhood are also associated with obesity and poor fitness in adulthood. So it is suggested that for children, interventions that aim to reduce sedentariness should start early in life.
The perspective of too much sitting is distinct from too little exercise. Also, breaks in sedentary time is distinct from the overall volume of time spent being sedentary.
The suggestion to avoid the adverse impact of prolonged sedentary time is a feasible approach to promote light intensity activities as a way of ameliorating its deleterious health consequences. Read the Research
