目的：评估有效性的减肥干预措施在管理式护理setting.Methods：三臂随机临床试验：日常护理，邮件和电话干预。参与者是1801名超重管理式护理组织（MCO）成员。测量指标包括基线身高、基线和24个月时的体重、18个月时自我报告的体重。干预和参与其他体重相关的programmes.Results监测在24 months.Results：体重减轻分别为2.2，2.4，和1.9公斤，在18个月的邮件，电话和常规护理组，分别。邮件和电话组的体重变化与常规护理组无显著差异（P < 0.35）。24个月时的体重减轻在不同条件下没有差异（0.7 kg邮件，1.0 kg电话和0.6 kg常规护理，P=0.55）。尽管治疗可用性超过24个月，但参与率在6个月后下降。参与是18个月时邮件和电话组以及24个月时邮件组结果的重要预测因素。电话咨询的成本效益为132美元每1公斤的体重损失与邮件和日常护理实现类似的成本效益为72美元每1公斤的weightloss.Conclusion：虽然邮件和电话为基础的减肥计划是一个合理有效的方式来提供减肥服务，需要额外的工作，以提高其短期和长期的疗效。
Objective: Evaluate effectiveness of weight-loss interventions in a managed care setting.Methods: Three-arm randomized clinical trial: usual care, mail, and phone intervention. Participants were 1801 overweight managed care organization (MCO) members. Measures included baseline height, weight at baseline and 24 months, self-reported weight at 18 months. Intervention and participation in other weight-related programs was monitored across 24 months.Results: Weight losses were 2.2, 2.4, and 1.9 kg at 18 months in the mail, phone, and usual care groups, respectively. Mail and phone group weight changes were not significantly different from usual care (P < 0.35). Weight losses at 24 months did not differ by condition (0.7 kg mail, 1.0 kg phone, and 0.6 kg usual care, P=0.55). Despite treatment availability over 24 months, participation diminished after 6 months. Participation was a significant predictor of outcomes in the mail and phone groups at 18 months and the mail group at 24 months. Cost-effectiveness of phone counseling was $132 per 1 kg of weight loss with mail and usual care achieving similar cost-efficiency of $72 per 1 kg of weight loss.Conclusion: Although mail- and phone-based weight-loss programs are a reasonably efficient way to deliver weight- loss services, additional work is needed to enhance their short-and long-term efficacy.
