This study assessed the proportion of US adults with excess weight and obesity who consider bariatric surgery to be appropriate for themselves and how their own weight perception influences this consideration.
A stratified sample of 920 US adults in June 2014 was obtained through an online survey. The respondents were queried about bariatric surgery acceptability and personal weight perception. Average body mass index (BMI) was determined for each demographic variable, and responses were characterized according to BMI and concordance with perceived weight status. Chi-square analyses served to assess perceived weight concordance in relation to bariatric acceptance.
Only 32% of respondents with Class III obesity indicated that bariatric surgery would be an acceptable option for them, most often because they considered it to be too risky. Respondents with Class III obesity and concordant perception of weight status were more likely (P < 0.03) than discordant Class III respondents to accept bariatric surgery. Likewise, concordant respondents with excess weight, but not obesity, were more likely (P < 0.001) to correctly consider bariatric surgery to be inappropriate for them.
Despite good safety and efficacy, many persons still believe bariatric surgery is too risky. Weight perception concordance or discordance influences one's decision to consider this treatment option.
本研究评估了美国超重和肥胖成年人中认为减肥手术适合自己的比例，以及他们自身的体重认知如何影响这一考量。
2014年6月通过在线调查获得了920名美国成年人的分层样本。询问了受访者对减肥手术的可接受性和个人体重认知。确定了每个人口统计学变量的平均体重指数（BMI），并根据BMI以及与感知体重状况的一致性对回答进行了分类。卡方分析用于评估与减肥手术接受度相关的感知体重一致性。
只有32%的III级肥胖受访者表示减肥手术对他们来说是一个可接受的选择，最常见的原因是他们认为手术风险太大。与体重状况感知不一致的III级受访者相比，体重状况感知一致的III级肥胖受访者更有可能（P < 0.03）接受减肥手术。同样，体重超重但非肥胖且感知一致的受访者更有可能（P < 0.001）正确地认为减肥手术不适合他们。
尽管减肥手术具有良好的安全性和有效性，但许多人仍然认为其风险太大。体重感知的一致或不一致会影响一个人考虑这种治疗选择的决定。
