Abstract

BACKGROUND

Unrealistic expectations of weight loss are prevalent in obese patients and can negatively affect their adherence to dietary and health goals. We sought to examine the expectations and perceived notions about weight loss in candidates for bariatric surgery.

METHODS

A total of 284 consecutive and prospective bariatric patients were surveyed using a validated Goals and Relative Weights questionnaire before an educational seminar. The participants categorized their weight loss expectations as "dream," "happy," "acceptable," and "disappointed" and rated the effect of surgically-induced weight loss on 21 indicators of health, quality of life, social functioning, and self-image on a 1-10 scale. The data are presented as the mean +/- standard deviation.

RESULTS

Of the 284 patients, 230 were women and 54 were men (age 45 +/- 10 years; body mass index 50 +/- 8 kg/m(2)). These patients stated that their "dream" weight would be 89% +/- 8% excess body weight loss and that 77% +/- 9%, 67% +/- 10%, 49% +/- 14% excess body weight loss would be their "happy," "acceptable," and "disappointed" weight, respectively. Participants ranked health, fitness, body image, work performance, and self-confidence as the most important benefits of bariatric surgery. Women had greater "happy" and "acceptable" weight loss expectations and put more emphasis on physical presence (r = .17-.33, P <.01). Younger patients put more emphasis on attractiveness and improvements in social and sex life after bariatric surgery (r = .15-.19, P <.01).

CONCLUSION

The results of our study have shown that although the candidates for bariatric surgery understand its benefits, they have unrealistic expectations of weight loss. In our study, the patients' most modest weight loss expectation, the "disappointed" weight, was equivalent to what providers would consider a successful weight loss outcome after bariatric surgery. Setting realistic expectations is an important aspect of the preoperative evaluation and education, especially for younger women.

摘要

背景

肥胖患者中对体重减轻的不切实际期望很普遍，这可能会对他们坚持饮食和健康目标产生负面影响。我们试图研究减肥手术候选人对体重减轻的期望和认知观念。

方法

在一次教育研讨会前，使用经过验证的目标和相对体重问卷对总共284名连续的前瞻性减肥患者进行了调查。参与者将他们的体重减轻期望分为“理想”“满意”“可接受”和“失望”，并在1至10分的量表上对手术引起的体重减轻对21项健康、生活质量、社会功能和自我形象指标的影响进行评分。数据以平均值±标准差表示。

结果

在284名患者中，230名是女性，54名是男性（年龄45±10岁；体重指数50±8kg/m²）。这些患者表示，他们的“理想”体重将是超出体重减轻89%±8%，而超出体重减轻77%±9%、67%±10%、49%±14%将分别是他们的“满意”“可接受”和“失望”体重。参与者将健康、健身、身体形象、工作表现和自信心列为减肥手术最重要的益处。女性有更高的“满意”和“可接受”体重减轻期望，并且更强调外在形象（r = 0.17 - 0.33，P < 0.01）。年轻患者更强调减肥手术后的吸引力以及社交和性生活的改善（r = 0.15 - 0.19，P < 0.01）。
