对营养和体力活动行为变化的中介变量分析（MVA）进行评价，并提出建议。以理论为基础的行为营养和体力活动干预措施旨在改变被假设为对感兴趣的结果变化负责的中介变量。MVA是有用的，因为它们有助于确定最有前途的理论方法，中介和行为改变的干预组成部分。然而，目前的文献表明，MVA往往是不适当的进行，了解不多，不充分的介绍。解释了已发表文献中遇到的主要问题，并提出了克服当前实践弱点的建议。使用最合适的，目前可用的MVA方法，以及正确，全面的介绍和解释他们的发现，对于了解如何治疗和预防肥胖是至关重要的。
To critique current practice in, and provide recommendations for, mediating variable analyses (MVA) of nutrition and physical activity behaviour change. Theory-based behavioural nutrition and physical activity interventions aim at changing mediating variables that are hypothesized to be responsible for changes in the outcome of interest. MVA are useful because they help to identify the most promising theoretical approaches, mediators and intervention components for behaviour change. However, the current literature suggests that MVA are often inappropriately conducted, poorly understood and inadequately presented. Main problems encountered in the published literature are explained and suggestions for overcoming weaknesses of current practice are proposed. The use of the most appropriate, currently available methods of MVA, and a correct, comprehensive presentation and interpretation of their findings, is of paramount importance for understanding how obesity can be treated and prevented.
