Atividade física no deslocamento em adultos e idosos do Brasil: prevalências e fatores associados

Abstract

Although evidences proving the benefits of an active lifestyle, recent evidence in the literature has shown that levels of physical inactivity are increasing. Aiming to combat the high rates of sedentarism, physical activity began to be analyzed in different domains. Among the four different domains, physical activity in the commuting form has become the object of study and interventions. Nevertheless, data representing populations are rare, both in developed and developing countries. The aim of this study is to describe the prevalence of insufficient physical activity in commuting context and associated factors in adults and elderly people, in a representative sample of Brazil. The present study is characterized as an epidemiological cross-sectional population-based, with a sample of Brazilian adults and elderly residents of urban areas of municipalities of small, medium and large population size. The sampling was carried out in multistage, stratified according to the size of the population. The approach was made independently for adults and seniors. Considering the different sizes, the one hundred municipalities were randomly selected. After their identification, the census tracts were defined by raffles. Households were selected in each sector through a random start and a jump routine. All individuals who met the inclusion criteria were invited to participate. It was collected socioeconomic, demographic and health-related information. For the implementation of the specific outcome of this study it was used the long version of the International Physical Activity Questionnaire (IPAQ)
