N1 - Funding Information:
This article is based on data from the study “Pelotas Birth Cohort, 1993” conducted by the Postgraduate Program in Epidemiology at Universidade Federal de Pelotas with the collaboration of the Brazilian Public Health Association (ABRASCO). From 2004 to 2013, the Wellcome Trust supported the 1993 birth cohort study. The European Union, National Support Program for Centers of Excellence (PRONEX), the Brazilian National Research Council (CNPq), and the Brazilian Ministry of Health supported previous phases of the study. GIM was funded by a scholarship from the Coordinator for the Improvement of Higher Education Personnel (CAPES). This work was supported by a partnership between CAPES, Federal University of Pelotas and School of Human Movement and Nutrition Sciences, University of Queensland that enabled international collaborative work to be undertaken (CAPES: 99999.006937/2014-04). The work of UE and SB was supported by the UK Medical Research Council (MC_UU_12015/3). The authors have no conflicts of interest that are directly relevant to the content of this review. None of these organizations have influence in the study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication.

N2 - Socioeconomic position (SEP) is a potential correlate of sedentary behavior in adolescents. The aim of this study was to examine the associations between SEP and self-reported and objective measures of sedentary behavior in adolescents, using a life-course approach. Data from the 1993 Pelotas (Brazil) Birth Cohort Study were analyzed (N = 5249). Cross-sectional and longitudinal associations between multiple SEP indicators (maternal education, family income, SEP composite, cumulative family income) at birth, 11, 15 and 18 years, and five sedentary behavior outcomes (≥ 4 h/day screen time; ≥ 4 h/day TV; ≥ 2 h/day computer; ≥ 2 h/day video game; ≥ 12.7 h/day objectively measured sedentary time) at 11, 15 and 18 years, were examined. In cross-sectional analyses, higher SEP was positively associated with more screen time at ages 11 and 15 years. There was a consistent and positive association between higher SEP with time spent using a computer, and with sedentary time assessed through accelerometry. SEP at birth had a positive and direct effect on screen, computer and total sedentary time at 18 years. Participants in the highest cumulative income group had higher odds of high sedentary behavior in screen (OR: 2.40; 95% CI: 1.50–3.54), computer (OR: 7.35; 95% CI: 4.19–12.89) and total sedentary time (OR: 5.40; 95% CI: 3.53–10.35), respectively, compared with their counterparts with lower cumulative income. Our findings showed that SEP is an early determinant of sedentary behavior in adolescents.
