【摘要】：研究目的:研究青少年的体力活动与青少年健康的关系,最重要的是要了解青少年体力活动的模式。目前,有加速度计、计步器等客观的测量方法测量青少年的体力活动,但是,体力活动问卷具有成本低廉以及易于收集等优点作为大样本调查的首选方法,在青少年体力活动的调查中,这些体力活动问卷发挥了重要的作用。国外目前应用较为广泛的是三天体力活动记录工具,其已经在多国进行了修订,我们国家尚未进行引用,因此本研究的目的是引进国外三日体力活动记录工具,并结合我国中学生作息规律、体力活动特点,对记录工具进行修订。研究方法:本文研究对象为北京市首都师范大学附属育新学校148名12-17岁中学生(男70人,女78人)。编写记录工具,以时间为回忆顺序,每天晚上睡觉前回忆当天从早上6:00到睡觉前的体力活动,ActiGraph GT3X+加速度计测量其七天体力活动,记录工具同加速度计提前一天一同发放,每日填写记录工具,次日收集前一天的记录工具。一周后统一回收加速度计和记录工具。选取记录工具平均每天能量消耗METS总分、中等体力活动(MPA)时间、高强度体力活动(VPA)时间、中高强度体力活动(MVPA)时间,再抽取记录工具的两组数据,每组都包括一个休息日和两个学习日,其中一组的学习日选取其中一天包含体育课,另外一组的学习日选取都不含体育课。选取加速度计每天的平均COUNTS、中等体力活动(MPA)时间、高强度体力活动(VPA)时间、中高强度体力活动(MVPA)时间进行比较。通过分析记录工具和加速度计体力活动水平的Spearman相关系数和Bland-Altman图来评价效度,通过组内相关系数评价重测信度。统计学水平为α=0.05。研究结果:研究有效调查148人,记录工具同加速度计测量值之间的Spearman系数处于0.246-0.557之间(P0.05)。Bland-Altman的一致性分析显示MPA、VPA、MVPA结果的一致性分别为94%、94%、95.56%,具有较高的效度。两次测量的平均每天METS总分的组内相关系数系数均大于0.7,表明该记录工具的信度较好。研究结论:本研究修订的三日体力活动记录工具具有较好的可靠性和有效性,可用于我国中学生的日常体力活动大样本调查。
[Abstract]:Objective: to study the relationship between physical activity and adolescent health, the most important thing is to understand the physical activity patterns of adolescents. At present, there are some objective measuring methods, such as accelerometers and pedometers, to measure the physical activity of teenagers. However, the physical activity questionnaire has the advantages of low cost and easy to collect. These physical activity questionnaires play an important role. At present, the three-day manual activity recording tool, which has been revised in many countries and has not been quoted in our country, is now widely used in foreign countries. Therefore, the purpose of this study is to introduce the physical activity recording tools of foreign countries in 3rd, and to combine the rules of working and rest of middle school students in our country and the characteristics of physical activity. Methods: 148 middle school students (70 males and 78 females) aged 12-17 years old from Yuxin School affiliated to Beijing Capital normal University were studied. Every night before going to bed, recall the physical activity from 6:00 to bedtime. The actiGraph GT3X accelerometer measures its physical activity for seven days. The recording tool is distributed one day in advance with the accelerometer, and the recording tool is filled in daily. The following day collected the recording tools of the day before. One week later, the accelerometer and the recording tool were unified. The average daily energy consumption of the recording tool was the total score of METS, the time of moderate physical activity, the time of high intensity physical activity, and the time of high intensity physical activity. Two sets of data were extracted from the recording tool. Each group included a rest day and two study days, and one of the study days included physical education. In the other group, no physical education class was included in the study day. The average count time of the accelerometer per day, MPAs of moderate physical activity, and VPAs of high-intensity physical activity were chosen. The Spearman correlation coefficient and Bland-Altman diagram of physical activity level of recording tools and accelerometers were analyzed to evaluate the validity. The reliability of retest was evaluated by intra-group correlation coefficient. The statistical level was 伪 -0.05.Results: 148 subjects were investigated effectively. The Spearman coefficient between the recording tool and the measured value of the accelerometer was between 0.246-0.557. The consistency analysis of MPA-Altman showed that the consistency of the MPA-VPA-MPA-MVPA results was 940.94 / 95.56 and had higher validity. The intra-group correlation coefficient of the total average daily METS score measured twice was higher. The coefficients were all greater than 0.7, which indicated that the reliability of the recording tool was good. Conclusion: the physical activity recording tool revised in this study in 3rd had better reliability and effectiveness. It can be used to investigate the large sample of daily physical activity of middle school students in our country.
