Few empirical reports of studies examining the association between bariatric after care support group attendance and weight loss outcomes have been published. The present study investigated the association between the number of support group meetings attended and percentage of excess weight loss at 12 months after gastric banding surgery. The setting was a private practice at which no-cost, professionally led support group meetings were held weekly.
The medical records and support group attendance logs were examined for the dates of attendance, frequency of attendance (or no attendance) in relation to the percentage of excess weight loss (n = 102; 88.2% women; mean age 45.6 ± 11.3 years; mean baseline body mass index 46.4 ± 8.8 kg/m(2)). Linear regression models were used to assess the relationship between the number of group meetings attended and the percentage of excess weight of loss with age and baseline body mass index used as optional independent variables.
A significant linear relationship was found between support group meeting attendance and the percentage of excess weight loss with simple regression analysis (adjusted R(2) = .061, P = .007), with age (adjusted R(2) = .100, P = .002) and the baseline body mass index added to the model (adjusted R(2) = .072, P = .011).
The results of the present study add to the growing evidence of the positive relationship between the frequency of support group attendance and the percentage of excess weight loss. Future studies should examine patient motivational characteristics in relation to support group participation and other aspects of compliance with aftercare recommendations to investigate unique effects of each part of the treatment program on weight loss outcomes.
很少有研究报告对支持小组参加与减肥效果之间的关系进行实证研究。本研究调查了参加支持小组会议的次数与胃束带手术后 12 个月体重减轻百分比之间的关系。研究地点是一家私人诊所，每周都有免费的、由专业人员带领的支持小组会议。
检查了医疗记录和支持小组出勤记录，以确定出勤日期、出勤频率（或未出勤）与超重减轻百分比（n = 102；88.2%女性；平均年龄 45.6 ± 11.3 岁；平均基线体重指数 46.4 ± 8.8 kg/m2）之间的关系。使用线性回归模型评估参加小组会议次数与超重减轻百分比之间的关系，年龄和基线体重指数作为可选的独立变量。
简单回归分析发现支持小组会议出勤率与超重减轻百分比之间存在显著的线性关系（调整后的 R2 =.061，P =.007），年龄（调整后的 R2 =.100，P =.002）和基线体重指数添加到模型中（调整后的 R2 =.072，P =.011）。
本研究的结果增加了越来越多的证据表明，支持小组参加的频率与超重减轻的百分比之间存在积极的关系。未来的研究应检查与支持小组参与有关的患者动机特征以及其他方面的治疗后护理建议的遵守情况，以调查治疗方案的每个部分对减肥效果的独特影响。
