Sedentary behavior and physical inactivity from a comprehensive perspective.

To characterize the prevalence of physical activity in the population aged ≥16 years integrating sedentarism and physical inactivity. A cross-sectional study using data from the Galician Risk Behavior Data System (n=12,928) was conducted. The population was classified into four categories: physically active (active and non-sedentary), active but sedentary (active and sedentary), lightly active (inactive and non-sedentary), and extremely sedentary (inactive and sedentary). Prevalences were calculated for each category and a multinomial logistic regression model was fitted. 58.0% of the population was physically active and the remaining 42.0% presented some degree of sedentarism and/or physical inactivity. Men were more likely to be extremely sedentary. The risk of sedentarism decreased with age, and workers and/or students were prone to a higher risk of extreme sedentarism in comparison to those who reported other status. Extremely sendentary behaviors were also more common in people with higher educational levels, individuals living alone, residents of urban environments, and smokers. Joint evaluation of sedentarism and physical inactivity provides a more comprehensive and realistic picture of population behaviors related with physical activity. Since sedentarism is the most prevalent behavior, this study recommends that interventions be conducted at work and at academic environments.
