Adequate physical activity promotes physical and mental health and decreases obesity risk. However, most adolescents do not attain recommended physical activity levels and effective interventions are lacking. Physical activity trials rarely incorporate built environment use patterns.
This paper describes the design and rationale of the Children's Use of the Built Environment (CUBE) Study, an office-based intervention designed to teach youth how to use their surrounding built environment to increase physical activity.
CUBE is a 6-month intervention trial among 60 overweight and obese 10-16 year old adolescents from a community health center in Massachusetts. The study began in the winter of 2013. Patients are sequentially assigned to either the intervention or control group. Baseline physical activity by accelerometry and location by GPS, along with measured height, weight, and blood pressure are collected. Control subjects receive standard of care lifestyle counseling. Intervention subjects receive tailored recommendations on how to increase their physical activity based on their accelerometer and GPS data. Data collections are repeated at end-of-treatment, and again 3 months later.
The findings from this study should help guide future efforts to design interventions aimed at increasing adolescent physical activity as well as to inform design professionals and government officials charged with creating outdoor spaces where adolescents spend time.
充足的体育活动能促进身心健康并降低肥胖风险。然而，大多数青少年未达到推荐的体育活动水平，且缺乏有效的干预措施。体育活动试验很少纳入建成环境使用模式。
本文描述了儿童建成环境使用情况（CUBE）研究的设计和基本原理，这是一项基于办公室的干预措施，旨在教导青少年如何利用周围的建成环境来增加体育活动。
CUBE是一项针对来自马萨诸塞州一个社区健康中心的60名10 - 16岁超重和肥胖青少年的为期6个月的干预试验。该研究于2013年冬季开始。患者被依次分配到干预组或对照组。通过加速度计测量基线体育活动情况，通过全球定位系统确定位置，同时收集测量的身高、体重和血压。对照组接受标准的生活方式咨询。干预组根据其加速度计和全球定位系统数据获得关于如何增加体育活动的个性化建议。在治疗结束时重复数据收集，并在3个月后再次收集。
本研究的结果应有助于指导未来旨在增加青少年体育活动的干预措施设计工作，并为负责打造青少年活动户外空间的设计专业人员和政府官员提供参考。
