- 教育干预教育干预
背景情况:
- 低体力活动 (PA) 和高久坐行为 (SB) 是普遍存在的问题,特别是在教育程度较低的人群中.

- 职业教育的学生代表一个人群在不充分的PA和高SB的风险,需要有针对性的健康促进策略.
研究的目的:
- 评估多组件"让我们移动它"干预措施对职业学生行为和临床结果的有效性.

主要方法:
- 一个集群随机试验,涉及芬兰6个学校单位的1112名职业教育学生.
- 干预包括课堂活动机会和专注于动机和自我调节的课程,在为期2个月的密集期内进行.

主要成果:
- 干预没有对中度至强度的PA,整体SB或SB中断的共同主要结果产生显著影响.
- 与对照组 (8.6分钟) 相比,干预参与者在平日 (32分钟) 的每日总SB显著减少.
- 在干预组中,在学校时间内观察到加速计测量的光PA显著增加,干预的交付忠实度很好.
结论:
- 基于学校的"Let's Move It"干预措施没有改善休时间的体育活动,也没有显著改变职业学生的整体久坐行为.
