Factors associated with sedentary behavior among ELSA-Brasil participants: ecological model

Abstract

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 Longitudinal Study of Adult Health (ELSA-Brasil) assessed in the second wave (2012-2014). e SB was measured using questions related to sitting time during the week and weekend. e associated factors were assessed by face-to-face interviews, with blocks of questionnaires and anthropometric measurements. A hierarchical ecological model was built with all possible factors associated with SB: sociodemographic 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.

Comportamento sedentário de adultos e idosos durante a pandemia de COVID-19

“…Apesar de a maioria dos participantes não exceder o valor diário recomendado, não se pode negligenciar que 39% das pessoas ultrapassaram o ponto de corte considerado seguro para a saúde. Essa proporção é maior que os dados identificados no estudo longitudinal que acompanha uma amostra da população brasileira -23,7% para mulheres e 22,7% para homens 10 , o que nos permite inferir que o distanciamento social adotado pelos sujeitos do presente estudo pode ter provocado acréscimo no excessivo tempo sentado diariamente. Com isso, também se eleva o risco de incidência de doenças metabólicas e cardiovasculares, associadas ao excessivo tempo sentado 21 .…”

Body image distortion among Brazilian and Portuguese women with children: A comparative study between the ELSA-Brasil and Generation XXI cohorts

“…Participants were also asked whether they had ever drunk alcohol in their lifetime, even if occasionally (yes/no). In both the ELSA-Brasil and the Generation XXI cohorts, leisure-time physical activity was measured using the International Physical Activity Questionnaire, with respondents then being classified as physically active or not (Haskell et al, 2007;Pitanga et al, 2018).…”

Comportamentos sedentários e sua relação com os componentes da síndrome metabólica em quilombolas

“…No estudo ELSA-BRASIL que investigou fatores associados aos CS em 13.765 pessoas de ambos os sexos, por meio de regressão logística, encontrou associação positiva com a obesidade abdominal e o tempo sentado ≥8h/dia (Pitanga et al 2018). Assim, deve-se ter cautela ao comparar os resultados destes estudos, tendo em vista que utilizaram diferentes populações, formas de mensurar e categorizar os CS.…”
