背景。超重和肥胖的日益流行突出表明，需要以证据为基础、易于传播的体重管理干预措施，这些干预措施可以在人群基础上提供。跨理论模型（TTM）为多种行为体重管理干预提供了一个有前途的理论框架。超重或肥胖的成年人（BMI 25-39.9; n = 1277）在0、3、6和9个月时随机分为无治疗对照组或以家庭为基础的、阶段匹配的多重行为干预组，干预最多三种与体重管理相关的行为。所有参与者在6个月、12个月和24个月时再次接受评估。在健康饮食（47.5%对34.3%）、运动（44.90%对38.10%）、情绪困扰管理（49.7%对30.30%）和未经治疗的水果和蔬菜摄入（48.5%对39.0%）方面发现了显著的治疗效果，在24个月时进展为行动/维持。两组在24个月时的减重情况有所不同。行为改变的共变在治疗组中发生了，并且更加明显，在治疗组中，个体在一种行为上进展到行动/维持的可能性是在另一种行为上进展的2.5-5倍。多种行为干预的效果是单一行为干预的3倍以上。这项研究证明了基于ttm的定制反馈在改善健康饮食、锻炼、管理情绪困扰和人口体重方面的能力。治疗产生了高水平的人口影响，未来的多重行为干预可以寻求超越。(c) 2007爱思唯尔公司版权所有。
Background. The increasing prevalence of overweight and obesity underscores the need for evidence-based, easily disseminable interventions for weight management that can be delivered on a population basis. The Transtheoretical Model (TTM) offers a promising theoretical framework for multiple behavior weight management interventions.Methods. Overweight or obese adults (BMI 25-39.9; n = 1277) were randomized to no-treatment control or home-based, stage-matched multiple behavior interventions for up to three behaviors related to weight management at 0, 3, 6, and 9 months. All participants were re-assessed at 6, 12, and 24 months.Results. Significant treatment effects were found for healthy eating (47.5% versus 34.3%), exercise (44.90% versus 38.10%), managing emotional distress (49.7% versus 30.30%), and untreated fruit and vegetable intake (48.5% versus 39.0%) progressing to Action/Maintenance at 24 months. The groups differed on weight lost at 24 months. Co-variation of behavior change occurred and was much more pronounced in the treatment group, where individuals progressing to Action/Maintenance for a single behavior were 2.5-5 times more likely to make progress on another behavior. The impact of the multiple behavior intervention was more than three times that of single behavior interventions.Conclusions. This study demonstrates the ability of TTM-based tailored feedback to improve healthy eating, exercise, managing emotional distress, and weight on a population basis. The treatment produced a high level of population impact that future multiple behavior interventions can seek to surpass. (c) 2007 Elsevier Inc. All rights reserved.
