The main objective was to identify the prevalence and factors associated with sedentary behavior (SB). The study comprising a total of 13,765 individuals of both sexes participating in the Longitu-dinal Study of Adult Health (ELSA-Brasil) assessed in the second wave (2012-2014). The SB was measured using questions related to sitting time during the week and weekend. The associated factors were assessed by face-to-face interviews, with blocks of questionnaires and anthropometric meas-urements.
A hierarchical ecological model was built with all possible factors associated with SB:
so-ciodemographic environment (age and level of education; economic status); behavioral environment (leisure time physical activity, commuting physical activity, beer consumption, current smoking); and biological environment (overweight, obesity and abdominal obesity). Crude and adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated using logistic regression. Among men and women, higher education, current smoking and abdominal obesity were positively associated with SB, while being over 51 years old and being physically active were negatively associated with SB. The proposed ecological model explains the SB through the sociodemographic, behavioral and biological environment
O objetivo principal do estudo foi identificar a prevalência e fatores associados ao comportamento sedentário (CS). O estudo compreendeu um total de 13.765 indivíduos de ambos os sexos participantes do Estudo Lon-gitudinal de Saúde do Adulto (ELSA-Brasil) avaliados na segunda onda (2012-2014). O CS foi medido usando questões relacionadas ao tempo sentado durante a semana e o final de semana. Os fatores associados foram avaliados por meio de entrevistas face a face com blocos de questionários e medidas antropométricas.
