There is extensive evidence regarding the role of physical inactivity and an increased risk of all-cause mortality. However, to date, no follow-up studies have been conducted in Chile that analyze this association considering sociodemographic, lifestyle, and health factors.
The study analyzes the association between physical inactivity and the risk of all-cause mortality in the Chilean population over 15 years of age, considering the differential effects of sociodemographic, lifestyle, and health factors on this relationship.
The analysis is based on data from the 2009–2010 National Health Survey (NHS), conducted by the Chilean Ministry of Health. It is a prospective study with 10.3 years of follow-up and includes 4,539 participants.
According to the results, physically inactive individuals have, on average, 5.8 fewer years of life expectancy compared to those who meet physical activity recommendations. Furthermore, women aged 60 and older, residents of urban areas, and individuals with medium to high educational attainment and high income levels are at significantly higher risk of all-cause mortality associated with physical inactivity.
