目标： 1. 识别通过互联网程序寻求体重问题帮助的个人的特征。 2. 确定此类计划长期成功的指标。方法：使用基于互联网的体重俱乐部（www.viktklubb.se），该俱乐部由计算体重指数（BMI）、食物能量含量和运动能量成本的标准算法组成。所有成员都填写了基本数据，并可以自愿填写其他与研究相关的问题。连同有关治疗成功、人员流失和项目各个组成部分使用情况的数据，这些信息被自动监控并下载到数据库中。结果：86% 的成员为女性，年龄范围广泛（范围 18-101 岁；平均 40.3 +/- 11.5 岁）。基线时，整个组的 BMI 为 29.3 +/- 5.1 kg/m(2)，其中 39% 肥胖，45% 超重。在完成者中，16% 的人从超重或肥胖变为正常体重。这相当于 29% 的会员体重减轻了 5-9.9%，20% 的会员体重减轻了 10% 以上。减肥的最强预测因素是体重俱乐部的活动，根据登录次数、日记条目和性别来判断。结论：观察到相当大但看似随机的退出率，以及完成者的网络计划活动与体重减轻之间存在显着的剂量反应效应。鉴于其低成本和全天 24 小时的高可用性，这种形式的项目交付值得进一步评估和开发，特别是在人员流失方面。
Aims: 1. To identify characteristics of individuals seeking help for their weight problem via an internet-based programme. 2. To identify indicators of long term success in such a programme. Methods: An internet-based weight club (www.viktklubb.se) was used consisting of standard algorithms for calculating body mass index (BMI), food energy content and exercise energy cost. All members filled in basic data and could volunteer to fill in additional research related questions. Together with data on treatment success, attrition, and use of the various components of the programme, this information was automatically monitored and downloaded to a database. Results: Eighty-six percent of the members were female, and the age range was wide (range 18-101 years; mean 40.3 +/- 11.5 years). At baseline, BMI of the entire group was 29.3 +/- 5.1 kg/m(2) with 39% obese and 45% overweight. Among the completers, 16% changed from overweight or obese to normal weight. This corresponded to 29% of the members losing 5-9.9% of their initial body weight and 20% losing >= 10% of their. The strongest predictors of weight loss were activity in the weight club as judged by number of logins and diary entries, and sex. Conclusions: A sizeable, but seemingly random, dropout rate was observed, together with significant dose-response effects between activity in the internet-based program and weight-loss among completers. Given its low cost and high accessibility at 24 hours a day, this form of programme delivery is interesting to evaluate and develop further, especially regarding attrition.
