目的：调查是否久坐不动的行为，在上学时间与性别，年龄，母亲的教育，有体育课，体重状况，和学业performance.Design：横断面study.Methods：一个样本的571名儿童（7-12岁），从五所小学在弗洛里亚诺波利斯，巴西南部有他们的身高和体重测量，并戴加速度计在上课时间。老师们填写了一份表格来评估孩子们的阅读和写作能力。父母提供了社会人口和教育信息。结果：儿童在校期间久坐行为的平均时间为132 min，占总在校时间的64%。女孩（137.5分钟），肥胖儿童（138.1分钟），年龄较大的儿童（144.2分钟），和那些谁没有体育课（140.2分钟）花更多的时间从事久坐不动的活动比他们的同龄人。学习成绩和母亲的教育与久坐behaviors.Conclusions：孩子们花了大部分的上学时间在久坐的活动，与女孩，年龄较大的学生，肥胖的学生比他们的同龄人更久坐不动。体育课是防止学校过度久坐行为的保护因素。减少在校期间久坐不动行为的干预措施可以采用其他策略，使高危人群受益。此外，鼓励学生参与体育课可以减少在上课时间久坐不动的时间。(C)2016年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Objectives: To investigate whether sedentary behavior during school-time is associated with gender, age, mother's education, having physical education classes, weight status, and academic performance.Design: Cross-sectional study.Methods: A sample of 571 children (7-12 years old) from five elementary schools in Florianopolis, South Brazil had their height and weight measured, and wore accelerometers during class time. Teachers completed a form to evaluate children's reading and writing skills. Parents provided sociodemographic and educational information. Data was analyzed using multilevel linear regression analyses.Results: Children spent an average of 132 min in sedentary behavior during school-time (64% of total school-time). Girls (137.5 min), obese children (138.1 min), older children (144.2 min), and those who did not have physical education classes (140.2 min) spent more time engaged in sedentary activities than their peers. Academic performance and mother's education were not associated with sedentary behaviors.Conclusions: Children spent most of their school-time in sedentary activities, with girls, older students, and obese students being even more sedentary than their peers. Physical education classes were a protective factor against excessive sedentary behavior in school. Interventions for reducing sedentary behavior during school-time could employ additional strategies to benefit the at risk groups. In addition, encouraging student's participation in physical education classes could minimize the time spent in sedentary behavior during school hours. (C) 2016 Sports Medicine Australia.
