Insight into the role of energy balance-related behaviours (EBRB) is of great importance when it comes to prevention of weight gain and design of interventions tailored to target these behaviours.
First, the present study examines the longitudinal association of four EBRB in Norwegian adolescents. Second, it aims to examine whether clusters of EBRB are cross-sectionally associated with being overweight.
The present study is part of the 'Fruits and Vegetables Make the Marks' project. The study sample consists of twenty control schools in two Norwegian counties.
Survey questionnaires were completed by 884 pupils with an average age at baseline, September 2001, of 11·8 years. In the follow-up surveys in May 2002 and May 2005, a total of 809 and 724 adolescents participated, respectively. Four EBRB were measured: habitual fruit and vegetable intake, snacking and soda consumption, television and computer use and physical activity.
Results of the associations between EBRB were similar for boys and girls. The odds, ranging from 1·14 to 12·06, were mostly significant. One out of four clusters, the unhealthy cluster, was significantly and cross-sectionally associated with overweight and obesity.
Longitudinal associations of EBRB show that it is important to start early with interventions that aim to prevent unhealthy behaviours becoming habitual. These behaviours should be targeted at the same time as they tend to co-occur. More research, preferably longitudinal and more objective, is needed to investigate associations between health behaviours and body weight among adolescents.
在预防体重增加和设计针对这些行为的干预措施时，深入了解与能量平衡相关的行为（EBRB）的作用非常重要。
首先，本研究检验了挪威青少年四项 EBRB 的纵向关联。其次，它旨在检验 EBRB 聚类是否与超重存在横断面关联。
本研究是“水果和蔬菜成就卓越”项目的一部分。研究样本由挪威两个县的二十所对照学校组成。
在基线（2001 年 9 月），884 名平均年龄为 11.8 岁的学生完成了调查问卷。在 2002 年 5 月和 2005 年 5 月的后续调查中，共有 809 名和 724 名青少年参与。测量了四项 EBRB：习惯性水果和蔬菜摄入量、零食和苏打水消费、电视和电脑使用以及体育活动。
EBRB 之间的关联结果在男孩和女孩中相似。比值范围从 1.14 到 12.06，大多数都具有显著性。四个聚类之一，即不健康聚类，与超重和肥胖存在显著的横断面关联。
EBRB 的纵向关联表明，早期开展旨在预防不健康行为成为习惯的干预措施非常重要。这些行为应该同时作为目标，因为它们往往同时发生。需要更多的研究，最好是纵向和更客观的研究，以调查青少年健康行为与体重之间的关联。
