(1) Background: Children's overweight and obesity are a growing public health problem. The aim of this study was to assess the influence of physical activity (PA) at school on body mass of children aged 10-12 during 2 years of observation. (2) Methods: Primary school children ( = 245, 48% girls and 52% boys) took part in the study. Children were divided in two groups, (1) of standard PA and (2) of elevated PA at school corresponding to 4 and 10 h of physical education lessons (PE) a week, respectively. Weight, height, and body mass index (BMI) were measured starting from the 4th grade and ending at the 6th grade of school. (3) Results: The number of children with excessive body weight (overweight and obese) increased by ¼ in children of standard PA while slightly decreased in children of elevated PA. Many more children of elevated PA changed body mass category from overweight to healthy weight than those of standard PA. Girls, especially of standard PA, had more often excessive body weight compared to boys. (4) Conclusions: Increasing time of physical activity at school by elevation of the number of PE lessons favorably affects the body mass of children.
(1) 背景：儿童超重和肥胖是一个日益严重的公共卫生问题。本研究的目的是评估在两年的观察期内，学校体育活动（PA）对10至12岁儿童体重的影响。(2) 方法：小学儿童（n = 245，48%为女孩，52%为男孩）参与了本研究。儿童被分为两组，（1）标准体育活动组和（2）学校体育活动增加组，分别对应每周4小时和10小时的体育课（PE）。从四年级开始到六年级结束测量体重、身高和体重指数（BMI）。(3) 结果：标准体育活动组儿童中超重（超重和肥胖）儿童数量增加了四分之一，而体育活动增加组儿童数量略有下降。与标准体育活动组相比，体育活动增加组中更多儿童的体重类别从超重变为健康体重。与男孩相比，女孩，尤其是标准体育活动组的女孩，超重情况更为常见。(4) 结论：通过增加体育课节数来增加学校体育活动时间对儿童体重有积极影响。
