Bariatric surgery is recognized as the most effective method for achieving relevant weight loss in subjects with severe obesity. However, there is insufficient knowledge about weight self-regulation and quality of motivation in these patients. The main goal of this study was to characterize the association between the percentage of excess weight loss (%EWL) and the motivation to manage weight, at least 1 year after sleeve gastrectomy (SG). This is an observational longitudinal retrospective study. All patients corresponding to predefined inclusion criteria who underwent SG from January 2008 to July 2010 at a main general hospital were invited. A version of the Treatment Self-Regulation Questionnaire (TSRQ) was used to assess patients' quality of motivation: TSRQ concerning continuing the weight self-management program. Clinical data were collected from patients' records. Overall, 81 patients participated (16 men and 65 women, 25-64 years old). The average body mass index was significantly reduced from 45.3 ± 7.0 kg/m preoperatively to 32.7 ± 6.9 kg/m postoperatively. Autonomous self-regulation was higher than externally controlled self-regulation, regarding motives to keep managing weight after SG. Postoperatively, %EWL correlated negatively with external self-regulation. SG was found to be associated with the quality of motivation for losing weight. External motivations were associated with worse results. These findings support the importance of multiprofessional teams in the assessment and treatment of patients, aiming for the promotion of weight self-regulation after bariatric surgery.
减重手术被认为是重度肥胖患者实现显著体重减轻的最有效方法。然而，对于这些患者的体重自我调节和动机质量，我们了解不足。本研究的主要目的是描述在袖状胃切除术（SG）后至少1年，超重减轻百分比（%EWL）与体重管理动机之间的关联。这是一项观察性纵向回顾性研究。邀请了2008年1月至2010年7月在一家主要综合医院接受SG且符合预定义纳入标准的所有患者。使用治疗自我调节问卷（TSRQ）的一个版本来评估患者的动机质量：关于继续体重自我管理计划的TSRQ。从患者记录中收集临床数据。总体而言，81名患者参与（16名男性和65名女性，年龄25 - 64岁）。平均体重指数从术前的45.3±7.0 kg/m²显著降至术后的32.7±6.9 kg/m²。关于SG后保持体重管理的动机，自主自我调节高于外部控制自我调节。术后，%EWL与外部自我调节呈负相关。发现SG与减肥动机质量相关。外部动机与较差的结果相关。这些发现支持了多专业团队在评估和治疗患者方面的重要性，旨在促进减重手术后的体重自我调节。
