Previous research has shown that attachment anxiety is a good predictor of body mass index. This relationship is significantly mediated by disinhibited (over-) eating and is likely to reflect a specific form of affect regulation. This study explored whether obese bariatric surgery candidates (BSC; N=34) and bariatric surgery recipients (BSR; N=15) would show higher levels of attachment insecurity (higher attachment anxiety and/or higher attachment avoidance) than a group of age and gender-matched lean controls (N=54). Mediation analyses showed that compared to lean controls (M=2.96, SE=0.1), both BSC (M=3.5, SE=0.2) and BSR (M=3.4, SE=0.2) groups had a more insecure attachment orientation. These relationships were significantly mediated by disinhibited eating (BSC: lower limit confidence interval (LLCI)=0.06 and upper limit confidence interval (ULCI)=0.62; BSR: LLCI=0.02 and ULCI=0.76). There was no such relationship when the BSC and BSR groups were compared (LLCI=-0.15 & ULCI=0.3). These observations suggest that attachment insecurity may be a risk factor for obesity and bariatric surgery because of associated disinhibited eating. Moreover, these factors may be important to consider when bariatric surgery results in poor outcomes.
先前的研究表明，依恋焦虑是身体质量指数的良好预测指标。这种关系受到抑制（过度）进食的显著调节，可能反映了一种特定的情感调节形式。本研究探讨了肥胖症患者（BSC；N=34）和接受过减肥手术的患者（BSR；N=15）是否比年龄和性别匹配的瘦对照组（N=54）表现出更高的依恋不安全感（更高的依恋焦虑和/或更高的依恋回避）。中介分析显示，与瘦对照组（M=2.96，SE=0.1）相比，BSC 组（M=3.5，SE=0.2）和 BSR 组（M=3.4，SE=0.2）的依恋不安全感更强。这些关系受到抑制性进食的显著调节（BSC：下限置信区间（LLCI）=0.06，上限置信区间（ULCI）=0.62；BSR：LLCI=0.02，ULCI=0.76）。当比较 BSC 和 BSR 组时，没有这种关系（LLCI=-0.15，ULCI=0.3）。这些观察结果表明，依恋不安全感可能是肥胖和减肥手术的一个风险因素，因为它与相关的抑制性进食有关。此外，当减肥手术结果不佳时，这些因素可能需要考虑。
