目的定量测量北京市初中1～2年级学生在校期间(尤其是体育课上)的身体活动水平。方法选取北京市某初中1～2年级学生81名(男生37人,女生44人),用佩戴于髋关节的ActiGraph GT3X+型加速度计记录一周5d在校期间身体活动,评价平均每天和每节体育课上的身体活动水平。结果在校期间,平均每天参加中高强度活动时间女生为(47.2±16.0)min,男生为(67.3±20.5)min,女生显著低于男生(P<0.01);体育课上达到中高强度活动的时间比例男生平均为53.6%±10.2%,女生为35.2%±7.2%;不同BMI学生在校期间身体活动水平比较:平均每天身体活动水平男女各组间均无差异;体育课上,女生各组间无差异;与正常BMI组男生相比,消瘦、超重和肥胖组男生较高强度活动时间较短(P<0.05)。结论初中1～2年级女生身体活动强度较低;体育课对促进学生在校期间的身体活动有重要贡献,体育课日学生身体活动明显增加;体育课上,正常体重男生身体活动量最高。
Abstract：Objective To quantify the physical activity(PA) level during school time,especially in PE class,among Beijing junior school students.Methods 81 healthy adolescents(37 boys and 44 girls) aged 11-15 were recruited from grade 1-2 of a junior school,and a hip-worn ActiGraph GT3X+ accelerometer was used to measure students' PA.Accelerometer-determined steps,moderate-and vigorous-intensity PA(MVPA),vigorous-intensity PA(VPA) and MET-mins at school time and physical education(PE) class were assessed.Results During school time,girls spent(47.2±16.0)mins performing,and boys(67.3±20.5)mins per day(P<0.01).Boys also had more steps per day,VPA time and MVPA MET-min than girls(P<0.001).In PE class,boys spent 53.6%±10.2% of time in MVPA,as compared to girls' 35.2%±7.2%.Boys with normal BMI had the highest VPA time during PE than other groups(P<0.05).No significant BMI group differences in PA level were found in girls.Conclusion PA in school time was objectively qualified in Beijing junior school students.Girls were less active than boys.PE class provided a major portion of the VPA time and MVPA MET-min in school time PA for boys and girls.Boys with normal BMI had the highest PA level during PE classes.
