Background: Although evidence on the health effects of sedentary behavior (SB) has grown systematically in recent years, few developing countries have reported population levels of SB, especially in South America. Our objective was to describe time spent sitting in a representative sample from Chile categorized by age, gender, educational level, and body mass index (BMI).
Methods: A national health survey was conducted in Chile in a nationally representative sample ( = 5411) in 2009-2010.
