Title: Inactividad física versus sedentarismo: análisis de la Encuesta Nacional de Salud de Chile 2016-2017
Abstract: Background: Physical inactivity and sedentariness are independent risk factors for mortality. Physical inactivity is defined as engaging in insufficient moderate/vigorous physical activity (i.e. not meeting the WHO's recommendations). Sedentariness is defined according to sedentary behavior; evidence suggests that > 8 h/d could serve to consider a person as sedentary. The Chilean National Health Survey 2016-2017 (NHS), using a single question (Question-NHS), considered as âsedentaryâ those who did not engage in sports or physical activity for ⥠30 min, ⥠3 times/wk. Thus, it attempted to estimate sedentariness without considering sedentary behavior.
