The aim of this study was to assess whether our online closed community heart care support group and information resource could sustain changes in health behaviour after the moderators withdrew their support. Heart patients (n = 108) living in a deprived area of Greater Manchester were recruited from general practitioners' coronary heart disease registries. The sample for this randomized controlled trial was divided in half at random where half of the participants received password-protected access to our health portal and the other half did not. At 6 months follow-up (based on the moderated phase), there was a significant difference between the experimental group and the controls in terms of self-reported diet (eating bad foods less often). This change in behaviour was not sustained during the 3-month unmoderated phase. During this unmoderated phase of the intervention, the experimental group had significantly more health care visits compared with the controls. There was no significant difference between the two phases for either group in terms of exercise, smoking or social support. This study offers insight into the potential implications for health changes of moderating arrangements for online health communities.
本研究的目的是评估在主持人撤回支持后，我们的在线封闭社区心脏护理支持小组和信息资源能否维持健康行为的改变。从全科医生的冠心病登记册中招募了居住在大曼彻斯特贫困地区的心脏病患者（n = 108）。这项随机对照试验的样本被随机分成两半，其中一半参与者获得了访问我们健康门户网站的密码保护权限，另一半则没有。在6个月的随访中（基于有主持人阶段），实验组和对照组在自我报告的饮食方面（减少食用不良食物的频率）存在显著差异。在3个月的无主持人阶段，这种行为改变未能持续。在干预的这个无主持人阶段，与对照组相比，实验组的医疗保健就诊次数显著更多。两组在运动、吸烟或社会支持方面，两个阶段之间均无显著差异。本研究为在线健康社区的主持安排对健康变化的潜在影响提供了见解。
