BACKGROUND
It is an important condition for adequate weight loss and prevention of adverse events that bariatric surgery (BS) candidates possess good specific health knowledge. There is a paucity of standardized instruments to evaluate the specific health knowledge of patients before and after BS. Therefore, we developed a 32-item multiple-choice test covering the main aspects of life which are important after BS, and investigated the correlation of specific health knowledge with health literacy, level of depression and anxiety, percentage of excess weight loss, and specific complications of BS in postoperative patients.
METHODS
Two groups participated in the cross-sectional study: the preoperative group (n = 109) was recruited from candidates for BS (gastric bypass or sleeve gastrectomy), the postoperative group (n = 110) was recruited from patients 12-74 months after BS (average 33 months, SD = 16.5). Both groups had completed a preoperative multimodal training program. Specific health knowledge was assessed with a newly developed knowledge questionnaire. Health literacy was evaluated with the short version of the European Health Literacy Survey (HLS-EU-Q16). The 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Scale (GAD-7) were used to assess the levels of depression and anxiety.
RESULTS
The pre- and postoperative group did not differ with regard to the number of correctly answered questions on the knowledge questionnaire, with 75% correct answers in both groups (p = 0.059). No correlations were found with health literacy (p = 0.498) and levels of depression (preoperative group: p = 0.279; postoperative group: p = 0.242) and anxiety (preoperative group: p = 0.866; postoperative group: p = 0.119). In postoperative patients specific health knowledge was not associated with the weight loss achieved (p = 0.437).
CONCLUSION
The newly designed knowledge questionnaire can be useful for screening specific knowledge of BS patients at different time points.
背景
肥胖症手术（BS）候选人具备良好的特定健康知识是实现充分体重减轻和预防不良事件的重要条件。目前缺乏标准化工具来评估BS患者术前和术后的特定健康知识。因此，我们开发了一项包含32个项目的多项选择题测试，涵盖了BS术后重要的生活主要方面，并调查了特定健康知识与健康素养、抑郁和焦虑水平、超重减轻百分比以及术后患者BS特定并发症之间的相关性。
方法
两组参与了横断面研究：术前组（n = 109）从BS候选人（胃旁路手术或袖状胃切除术）中招募，术后组（n = 110）从BS术后12 - 74个月（平均33个月，标准差 = 16.5）的患者中招募。两组均完成了术前多模式培训计划。使用新开发的知识问卷评估特定健康知识。使用欧洲健康素养调查问卷简版（HLS-EU-Q16）评估健康素养。使用9项患者健康问卷（PHQ-9）和7项广泛性焦虑量表（GAD-7）评估抑郁和焦虑水平。
结果
术前组和术后组在知识问卷上正确回答问题的数量没有差异，两组的正确答案率均为75%（p = 0.059）。未发现与健康素养（p = 0.498）、抑郁水平（术前组：p = 0.279；术后组：p = 0.242）和焦虑水平（术前组：p = 0.866；术后组：p = 0.119）存在相关性。在术后患者中，特定健康知识与实现的体重减轻无关（p = 0.437）。
结论
新设计的知识问卷可用于筛查不同时间点BS患者的特定知识。
