Abstract

ObjectiveVerify the prevalence and sociodemographic and economic factors associated with behavior change stages for habitual physical activity practice in adolescents from Santa Catarina. MethodsSecondary analysis of a study on the Behavior of Adolescents from Santa Catarina (CompAC 2). Cross-sectional school-based study of 6,529 high-school students (males, n=2,903) from the state of Santa Catarina public education system in 2011, aged 15 to 19 years. Multinomial logistic regression (crude and adjusted) was used to measure the association. ResultsThe highest and lowest prevalence rates were found in the maintenance (43.9%) and precontemplation stages (7.0%), respectively. The stages of action, preparation and contemplation showed similar results: 16.2%; 17.0% and 15.6%; respectively. Male adolescents show higher prevalence in the maintenance stage in relation to females and these show a higher prevalence in preparation, contemplation and precontemplation. All the assessed variables (gender, age, area of residence, employment status, family income, maternal education and school grade), with the exception of school shift, were associated with at least one of the stages. ConclusionsA large proportion of adolescents are in the pre-adoption stages and most of these have the intention to start regular physical activity. With the exception of school shift, the assessed variables were associated with stages in different ways, showing different profiles in relation to sociodemographic and economic characteristics in each subgroup.

Highlights

There is a growing interest in the understanding of behavior related to physical activity (PA),[1] due to the recognition of its importance in health maintenance.[2]
The findings indicate a higher prevalence of adolescents in the maintenance stage and a lower prevalence in the precontemplation stage, which is in accordance with results of studies carried out in two areas of Brazil.[15]
De Bourdeauhiuj[12] found that of 5931 assessed adolescents, most were in the maintenance stage, but the lowest proportion was in the action stage

Summary

Introduction

There is a growing interest in the understanding of behavior related to physical activity (PA),[1] due to the recognition of its importance in health maintenance.[2] Given the fact that patterns of PA practice in adolescence tend to continue into adulthood,[3] studies that investigate the behavior of young individuals is of great importance. Several theories have contributed to improve the understanding of PA-related behavior, given its complexity.[4] The transtheoretical model is one of them, consisting of four constructs of which Stages of Behavior Change (SBC) are the most often researched.[5]. As for the contemplation stage, individuals think about the possibility of change, within a period of approximately six months. Those in the preparation stage have certain goals to start
