Exposure to sedentary behavior and associated factors in adolescents from the state of Sergipe, Brazil

Abstract

OBJECTIVE: To identify the level of exposure to sedentary behavior (ECS) and analyze its association with indicators of demographic and socioeconomic status in adolescents in the State of Sergipe in 2011 and 2016. METHODS: The study involves two epidemiological surveys with a cross-sectional design, carried out in 2011 and 2016, with a representative sample of students from the State Public School System of Sergipe, composed of 8,143 students (2011=3992; 2016=4151), aged between 14 and 19 years. The ECS associated with indicators of demographic and socioeconomic status in adolescents was investigated. Descriptive statistics and chi-square were used for statistical analysis. Crude and adjusted binary logistic regression were used. RESULTS: The prevalence of ECS was 46.2% (2011) and 44.8% (2016) and was associated with the age group of 14 to 15 years (2011 = OR: 1.45; 95% CI: 1.19-1.78 / 2016 = OR: 1.58; 95% CI: 1.28-1.94); female (2011 = OR: 1.46; 95% CI: 1.27-1.68 / 2016 = OR: 1.22; 95% CI: 1.06-1.40), adolescents living in urban areas (2011 = OR: 1.22; 95% CI: 1.05-1.42 / 2016 = OR: 1.48; 95% CI: 1.27-1.72) and who have mothers with high school education (2011 = OR: 1.73; 95% CI: 1.32-2.28) and with higher education (2016 = OR: 1.57; 95% CI: 1.16-2.11). CONCLUSION: There was a trend towards a reduction in the level of ECS. Interventions are suggested in urban areas and in subgroups more vulnerable to CS, such as adolescents aged 14 to 15 years and females.
