Resumo: The practice of physical activity (PA) has occupied a prominent space, given its direct relationship to health promotion and disease prevention. Some behaviors related to this practice are easily incorporated in childhood and tend to remain in adulthood, bringing significant benefits to overall health. In turn, sedentary behavior (SB) has grown, especially among children. This work aims to analyze time trends in physical activity and sedentary behavior in children 7-10 years enrolled in public schools in two regions of Vitoria / ES. Database built from two surveys conducted in the county in 2007 and 2011 was analyzed. Information about PA and SB were obtained with the aid of a questionnaire validated for infant and population variables identified for this study. The variable "Total Screen Time" (TTT) was established on the basis of time spent on television, video games and computer and identified children with TTT > 2h/day. Active commuting, PA and supervised play time were measured and the children were classified as "physically active" when PA ≥ 300min/semana. Quantitative variables were presented as mean ± standard deviation and analyzed in relation to gender, age, socioeconomic class, and study area. The trend over time was analyzed using chi- square test and significance level p < 0.05. Most children were classified as PA in two studies, 72 % and 62 %, respectively, but there was a significant reduction in PA weekly ( p < 0.001 ) and active commuting to school ( p < 0.001 ). Female students and those residing in the region of higher socioeconomic status had shorter AF in both studies. Daily use of screen devices increased from one study to another ( p < 0.05 ). Boys had higher TTT in both studies compared to girls. It was concluded that there was an increase in SB, especially in relation to computer use. It is possible that this scenario is related to improving the socioeconomic status of families in the two regions studied , but the fact of participating in supervised AF contributed to increase the percentage of physically active children at both times
