Best practices for patient education in bariatric surgery (BS) remain undefined. The aims of this study were to evaluate the effect of an online lecture on nutrition knowledge, weight loss expectations, and anxiety among BS candidates and present a new tool to assess this knowledge before BS.
An interventional non-randomized controlled trial on 200 BS candidates recruited while attending a pre-BS committee. The first 100 consecutive patients were assigned to the control group and the latter 100 consecutive patients to the intervention group and were instructed to watch an online lecture of 15-min 1-2 weeks prior to surgery. All participants completed a BS nutrition knowledge and the state-trait anxiety inventory (STAI) questionnaires at the pre-BS committee and once again at the pre-surgery clinic. Body mass index (BMI), comorbidities, surgery type, marital status, and number of dietitian sessions were obtained from medical records.
Data for paired study questionnaires scores were available for 128 patients (n = 69 and n = 59 for the control and intervention groups, respectively), with a mean age and BMI of 40.3 ± 11.4 years and 41.3 ± 4.9 kg/m, respectively. The BS nutrition knowledge and the state anxiety scores increased for both study groups at the pre-surgery clinic as compared to the pre-BS committee (P ≤ 0.028), but the improvement in the nutrition knowledge score was significantly higher for the intervention group (P = 0.030). No within or between-group differences were found for the trait anxiety items score. The "dream" and "realistic" weight goals were lower than the expected weight loss according to 70% excess weight loss (EWL) for both study groups at both time-points (P < 0.001 for all).
Education by an online lecture prior to the surgery improves BS nutrition knowledge, but not anxiety. ClinicalTrials.gov number: NCT02857647.
减重手术（BS）患者教育的最佳实践仍未定义。本研究旨在评估在线讲座对 BS 候选人营养知识、减肥预期和焦虑的影响，并提出一种新的工具来评估 BS 前的知识。
一项干预性非随机对照试验，纳入 200 名 BS 候选人，在参加 BS 委员会期间招募。前 100 名连续患者被分配到对照组，后 100 名连续患者被分配到干预组，并被指示在手术前 1-2 周观看 15 分钟的在线讲座。所有参与者在 BS 委员会前和手术前诊所完成 BS 营养知识和状态-特质焦虑量表（STAI）问卷。从病历中获取 BMI、合并症、手术类型、婚姻状况和营养师就诊次数。
对 128 名患者（对照组 n=69，干预组 n=59）的配对研究问卷评分数据进行了分析，平均年龄和 BMI 分别为 40.3±11.4 岁和 41.3±4.9kg/m。与 BS 委员会前相比，两组患者在手术前诊所的 BS 营养知识和状态焦虑评分均有所增加（P≤0.028），但干预组的营养知识评分改善更为显著（P=0.030）。两组特质焦虑项目评分均无组内或组间差异。两组在两个时间点的“梦想”和“现实”体重目标均低于根据 70%超重减轻（EWL）预期的减肥目标（P<0.001）。
手术前的在线讲座教育提高了 BS 的营养知识，但不能缓解焦虑。临床试验编号：NCT02857647。
