目的：方法：对肥胖症患者在3个不同的减肥阶段（筛选访视后的自发性减肥阶段、治疗前的体重下降阶段、治疗后的体重下降阶段）进行了体重相关因素和心理因素的测试（治疗前），减肥后的准备5周系列讲座（第一步）和后组治疗持续两个学期（第二步）在247名肥胖患者。预测步骤II治疗中体重减轻的最强因素是初始步骤I体重减轻。至少1公斤的体重减轻步骤！预测第二步体重减轻的变化为13%。筛选后自发性治疗前体重减轻和更多体重减轻史也与更多第II步体重减轻相关。心理障碍，如饮食失调和精神痛苦与减肥无关，自我报告的动机和体重控制点也不相关。的整体损耗率为63%，与教育程度较低，是一个移民，缺乏职业，以前的体重损失和较高的身体dissatisfaction.Conclusion：最初的体重损失是最确定的因素，用于预测治疗outcome.Practice的含义：治疗设计，包括一个介绍阶段，最低体重损失标准，继续治疗的建议。(C)2010爱思唯尔爱尔兰有限公司版权所有。
Objective: To identify pre-treatment factors related to weight loss in obesity treatment.Methods: Weight-related and psychological factors were tested in relation to three different weight loss phases: spontaneous weight loss after screening visit (Pre-treatment), weight loss after a preparatory 5-week series of lectures (Step I) and after group treatment lasting two semesters (Step II) in 247 obesity patients.Results: The strongest factor for predicting weight loss in the Step II treatment was initial Step I weight loss. At least 1 kg weight loss in Step! predicted 13% of the variation in Step II weight loss. Spontaneous pre-treatment weight loss after screening and a history of more weight losses were also related to more Step II weight loss. Psychological encumbrances such as eating disorders and mental distress were not related to weight loss, neither were self-reported motivation nor weight locus of control. The overall attrition rate was 63% and associated with lower education, being an immigrant, lack of occupation, fewer previous weight losses and higher body dissatisfaction.Conclusion: Initial weight loss is the most certain factor for predicting treatment outcome.Practice implication: A treatment design including an introductory phase with a minimum weight loss criterion for continuing treatment is suggested.
