Resumo: | The main objective of this study was to identify the association between combined effect of physical activity, reduction of screen time and overweight in adolescents. The sample of this cross-sectional study consisted of 613 adolescents, aged 15-18 years living in a municipality in northeasternBrazil. Physical activity was measured using the short-version IPAQ (International Physical Activity Questionnaire), and screen time was verified through two questions about the time that, on average, interviewees watched television, played video games, used the cell phone or computer on a normal weekday and one weekend day. The predictive power and cutoff points of screen time and physical activity for the outcome of interest were identified using the Receiver Operating Characteristic (ROC) curves. Different logistic regression models were proposed, with excess weight as dependent variable. In all models, the combination of little physical activity and long screen time was used as reference. A 95% confidence interval (CI) was used. In boys, the combination of physical activity and short screen time on a weekend day was inversely associated with overweight (OR = 0.31; 0.12-0.85). The combined effect of physical activity and reduced time spent watching TV, computer screen and similar devices on a weekend day is inversely associated with overweight in boys. |

O principal objetivo deste trabalho foi identificar a associação entre o efeito combinado da atividade física e redução do tempo de tela com excesso de peso em adolescentes. Oestudo foi transversal com amostra composta por 613 adolescentes, com idade entre 15 a 18 anos residentes em município do nordeste do Brasil. A atividade física foi medida por meio do IPAQ (International Physical Activity Questionnaire), versão curta e o tempo de tela foi verificado por meio de duas questões sobre o tempo que, em média o entrevistado assistia televisão, jogava videogame, usava o celular ou o computador em um dia de semana normal e em um dia no final de semana. O poder preditivo e os pontos de corte do tempo de tela e da atividade física para o desfecho de interesse foram identificados por meio das curvas Receiver Operating Characteristic (ROC). Foram propostos ainda diferentes modelos de regressão logística tendo o excesso de peso como variável dependente. Em todos os modelos de análise foi fixada como referência a combinação pouca atividade física e muito tempo de tela. Utilizou-se intervalo de confiança (IC) a 95%. Em rapazes, a combinação atividade física e pouco tempo de tela em um dia do final de semana foi inversamente associada ao excesso de peso (OR = 0,31; 0,12-0,85). O efeito combinado da atividade física e redução do tempo sentado frente a TV, tela de computador e assemelhados em um dia no final de semana está inversamente associado ao excesso de peso em rapazes.Universidade Federal de Santa Catarina.
