研究身体意象是否介导超重/肥胖与慢性病相关健康行为（CDRHP）之间的关联，包括缺乏体力活动（PA），不经常吃早餐（IBC），基于屏幕的媒体使用（SBM）和吸烟。2006年学龄儿童健康行为调查是对美国6-10年级（平均年龄= 14.3岁）学生的全国代表性样本（n = 8，028）进行的。结果变量包括PA，SBM，IBC和吸烟的自我报告的措施。身体形象采用身体投入量表（α = 0.87）中的5个项目进行评估，要求同意/不同意有关身体的陈述。根据性别分层，初始回归模型估计了超重/肥胖与CDRHP之间的关联。然后将包括身体意象的中介模型与初始模型进行比较，以确定身体意象在超重/肥胖和CDRHP之间的关系中的作用。在男孩中，身体形象介导的超重/肥胖与SBM，肥胖与IBC的关系。在女孩中，它介导了肥胖与PA、IBC和吸烟的关系，以及超重与SBM的关系。由于青少年男女超重/肥胖的患病率仍然很高，改善其身体形象的努力可能导致CDRHP参与频率降低。
To examine whether body image mediates the association between overweight/obesity and chronic disease-related health practices (CDRHP), including lack of physical activity (PA), infrequent breakfast consumption (IBC), screen-based media use (SBM), and smoking. The 2006 Health Behaviors in School-Age Children survey was administered to a nationally representative sample of US students (n = 8,028) in grades 6-10 (mean age = 14.3 years). Outcome variables included self-reported measures of PA, SBM, IBC, and smoking. Body image was assessed with 5 items from the Body Investment Scale (α = 0.87) asking for agreement/disagreement with statements about one's body. Stratifying on gender, an initial regression model estimated the association between overweight/obesity and CDRHP. Mediation models that included body image were then compared to the initial model to determine the role of body image in the relationship between overweight/obesity and CDRHP. Among boys, body image mediated the relationships of overweight/obesity with SBM, and of obesity with IBC. Among girls, it mediated the relationships of obesity with PA, IBC, and smoking, and of overweight with SBM. As the prevalence of overweight/obesity among adolescent boys and girls remains high, efforts to improve their body image could result in less frequent engagement in CDRHP.
