[Physical inactivity in Galicia (Spain): trends and the impact of changes in the definition]

Abstract

Objective: To estimate the prevalence of physical inactivity during leisure time in Galicia (Spain) between 2007 and 2011 and to assess the impact of including non-leisure time activities in the definition of physical inactivity.

Methods: A cross-sectional study was conducted in the population aged 16 years and older (n=19,235). Physical activity was assessed by the Minnesota Questionnaire. In 2011, inactivity was estimated by including daily activities.

Results: Between 2007 and 2011, the prevalence of inactivity in Galicia remained stable (p=0.249) and close to 50%. This prevalence was higher among women and those who worked or were in education. Inactivity decreased from 47% to 16% when non-leisure time activities were included in the definition.

Conclusions: Between 2007 and 2011 in Galicia, the prevalence of inactivity remained high and stable. This prevalence was significantly decreased when non-leisure time activities were included in the definition.
