Intervention Study on Increasing Physical Activity and Reducing Sedentary Behaviour of Vocational Students: Teacher Surveys 2015-2017

The intervention study investigated the effectiveness of the 'Let's Move It' programme aiming to increase physical activity (PA) and reduce sedentary behaviour (SB) among students in vocational schools in Finland. It was conducted as a cluster-randomised parallel group trial. This dataset consists of vocational school teachers' responses to three surveys on the 'Let's Move It' programme, practices and intervention measures relating to students' physical activity and sedentariness (sitting) during lessons, and opinions on and experiences of the programme. The research was funded by the Ministry of Education and Culture (OKM/81/626/2014) and the Ministry of Social Affairs and Health (201310238). The schools participating in the study were divided into intervention and control group schools. Therefore the participating teachers belonged either to the intervention or the control group. The intervention group participated in three 'Let's Move It' workshops. The surveys were conducted three times over the study period, partly repeating the same questions. The initial survey charted methods used during lessons to reduce students' sedentary time, time intervals of using the methods, the proportion of students who took the opportunity, the average time students were sedentary during one lesson, and the ways the teacher motivated them to reduce sedentariness. Further questions investigated views on what was too long a time for an uninterrupted sedentary period, the impact of reducing sedentariness during lessons, and the teacher's intention to take measures to reduce students' sedentary time over the following month. Workplace atmosphere and co-operation were also surveyed. The follow-up surveys contained also some new questions. In addition to intentions for the following month, they also surveyed the teacher's goals, plans and monitoring related to student sedentary behaviour, and the measures taken over the last month to reduce it. Open-ended questions charted changes noticed in the methods used by the school in general and other teachers. The intervention group surveys also asked the respondents to evaluate 'Let's Move It' workshops, programme and its materials. The use of sit-stand desks (height adjustable desks) and physical training equipment such as gym balls was investigate. Background variable included the respondent's gender, year of birth, years of working as a teacher, type of classroom in use, subject R taught and whether R belonged to the intervention or the control group.

本研究为干预研究，旨在探讨芬兰职业技术学校学生增加体力活动（PA）和减少久坐行为（SB）的‘让我们动起来’项目的有效性。该研究采用集群随机平行分组试验的方式进行。本数据集包含职业技术学校教师对‘让我们动起来’项目、学生在课程中体力活动与久坐（静坐）的实践及干预措施，以及对该项目的看法和体验的三次调查的回答。研究经费由教育部和文化遗产部（OKM/81/626/2014）以及社会事务和健康部（201310238）提供。参与研究的学校被分为干预组和对照组。因此，参与的教师要么属于干预组，要么属于对照组。干预组参加了三次‘让我们动起来’研讨会。调查在研究期间进行了三次，部分重复了相同的问题。初始调查描绘了在课程中减少学生静坐时间的策略、使用策略的时间间隔、利用机会的学生比例、一次课程中学生平均静坐时间，以及教师激励学生减少久坐的方式。进一步的问题调查了对于不间断静坐时间过长的看法、减少课程中久坐行为的影响，以及教师在接下来的一个月内采取措施减少学生静坐时间的意图。还调查了工作场所氛围与合作情况。后续调查还包含了一些新问题。除了对未来一个月的意图外，还调查了教师对学生久坐行为的目标、计划和监控，以及上个月采取的减少久坐行为的措施。开放式问题记录了学校在一般方法和其他教师中观察到的变化。干预组调查还要求受访者对‘让我们动起来’研讨会、项目及其材料进行评估。调查了可调节高度的坐立式桌椅和如健身球等体育训练设备的使用。背景变量包括受访者的性别、出生年份、担任教师的工作年限、所使用的教室类型、教授的科目R以及R是否属于干预组或对照组。
