INTRODUCTION: Sedentarism is a important public health problem in view of its association with several diseases and worse health status in adulthood. Physical activity habits adopted in childhood and adolescence tend to remain in adulthood. OBJECTIVES: To evaluate the prevalence of sedentarism and associated factors among adolescents in the city of Goiania. METHODS: This is a cross-sectional study with the population of students of 14 to 18 years old in the eastern region in the city of Goiania. Data collection occurred between February and September of 2010, involving 623 adolescents. We investigated demographic data, socioeconomic status, nutritional status and lifestyle habits (smoking, alcohol, physical activity). The sedentarism was measured with the International Physical Activity Questionnaire (short IPAQ) and was defined as practice moderate and/or vigorous physical activity for a period of less than 300 minutes per week. Statistics: t-student test, Mann-Whitney U, chi-square and logistic regression of Poisson. Level of significance: p <0.05. The project was approved by the Ethics Committee of the HC of UFG. RESULTS: The observed prevalence of sedentarism was 40.3%. Female adolescents, those who study at night, and those who drink alcohol had a higher prevalence of sedentarism. Also observed that the prevalence of sedentarism increased with age, especially among girls. Moreover, socioeconomic variables, the time per day watching TV, the habit of smoking and anthropometric changes were not associated with the prevalence of sedentarism. CONCLUSION: The prevalence of sedentarism is worst in girls, in adolescents who study at night and those who use to drink alcohol. Moreover, the increase of age favors the sedentarism among girls but don´t cause modifications in this habit among boys. Considering the large proportion of sedentary adolescents, it is necessary to intervention programs and health promotion in adolescence in order to improve the level of physical activity in adolescents and, consequently, produce healthier habits in adulthood.
