北京市主城区中学生身体活动水平及其影响因素

对北京市主城区中学生的身体活动水平进行评估,为中学生的体质健康促进提供数据支持.方法整群抽取北京市海淀区、东城区3所中学初一、初二、高一、高二年级学生共1 670名,使用青少年身体活动问卷(Physical Activity Questionnaire for Adolescents,PAQ-A)中文版进行身体活动评估.结果 青少年总体PAQ-A平均得分为(2.68±0.81)分,男生为(2.95±0.84)分,女生为(2.44±0.69)分,男生高于女生(I=6.41,P<0.01);中等到较大强度体力活动(MVPA)得分男生高于女生(t=7.53,P<0.01).平均每天视屏时间,男女均为100 min左右,差异无统计学意义.不论男女生,总体PAQ-A,MVPA高中生均低于初中生,视屏时间高中生高于初中生(P值均<0.01).学段、性别、父亲受教育水平均会影响身体活动水平.其中高中阶段(OR=2.24,95%CI=1.752.88)、女生(OR=3.42,95%CI=2.734.28)是引起身体活动不足的危险因素,而父亲文化为初中以下(OR=2.02,95%CI=1.133.64)、高中(OR=1.99,95%CI=1.322.99)、中专/大专(OR=1.56,95%CI=1.122.16)也是引起子女身体活动不足的危险因素.结论 高中生身体活动水平较低,视屏时间较长;男生身体活动水平高于女生;父亲受教育水平低者,子女的身体活动水平也较低.

Assessment of physical activity level and the influencing factors among middle school students in the main urban area of Beijing

Objective To evaluate the physical activity (PA) level and the influencing factors of middle school students in main urban area of Beijing, and to provide the data support for physical health of middle school students.Methods A total of1 670 middle school students in 3 schools of Haidian and Dongcheng District in Beijing were selected by cluster sampling method, and PA was evaluated with Chinese Version of Adolescent Physical Activity Questionnaire (PAQ-A).Results The average PA score was 2.68±0.81 for all the students, and 2.95± 0.84 for boys, 2.44± 0.69 for girls.PA level of boys was significantly higher than that of girls (t = 6.41, P<0.01), and moderate to vigorous physical activity (MVPA) of boys was also higher than girls' (P<0.01).The average daily screen time was 100 minutes for boys and girls, and there was no significant difference.Total PA and MVPA were higher in junior school students compared with the senior school students (P<0.01), but the screen time of senior school students was significantly higher than that of junior school students (P<0.01).Grade, gender and father's education level could significantly affect PA.Senior school (OR = 2.244, 95%CI = 1.75-2.88) and girls (OR = 3.42, 95%CI = 2.73-4.28) were risk factors for low PA.What' s more, compared with father with the postgraduate degree, the father at the educational level below the junior school (OR = 2.02, 95%CI = 1.13-3.64), senior school (OR = 1.99, 95%CI = 1.32-2.99), with polytechnic and college degree (OR= 1.56, 95%CI = 1.12-2.16) were also the risk factors for the children's PA deficiency.Conclusion Compared with the junior school students, the senior school students' PA is lower and the screen time is longer.PA of boys is higher than that of girls.PA of the children with father with low education level is also low.
