To compare eating behaviours within and between gastric bypass, sleeve gastrectomy and gastric band procedures and to investigate associations between eating behaviours and body weight.
Eating behaviours are subjective constructs representing physiological need and the hedonic need to eat. After metabolic surgery, eating behaviours have been observed to change. Little is known about whether eating behaviour change differs according to the metabolic procedure performed.
Adults (n = 204) with severe obesity from three countries were followed 1 year after metabolic surgical procedures (n = 121).
We measured eating behaviours using the Three-Factor Eating Questionnaire and used linear mixed models to compare eating behaviours within and between three procedure groups. We complied with the STROBE checklist for reporting observational studies.
Within groups, there were statistically significant increases in restraint and decreases in disinhibition and hunger. Between groups, we observed differences in disinhibition associated with the band procedure. There were no significant differences between any group for body weight or body mass index a year post-surgery. Disinhibition was the only eating behaviour associated with body weight, body mass index and the per cent of weight loss.
Eating behaviours in adults with severe obesity who underwent any of the three metabolic procedures were associated with eating behaviour change 1 year post-surgery. Disinhibition was the only eating behaviour that was associated with body weight.
Irrespective of the procedure, we found participants had a statistically significant increase in restraint and decreases in disinhibition and hunger 1 year post-surgery. Despite the significant reduction in disinhibition within the band group, this behaviour was more pronounced post-surgery compared with other groups. Although the reduction in hunger showed the greatest change, it was not associated with weight outcomes. This is relevant clinical knowledge for nurses who support bariatric surgical patients.
比较胃旁路术、袖状胃切除术和胃带术之间和之内的进食行为，并研究进食行为与体重之间的关系。
进食行为是代表生理需求和进食享乐需求的主观结构。代谢手术后，观察到进食行为发生了变化。对于根据所进行的代谢手术程序，进食行为变化是否存在差异，知之甚少。
来自三个国家的 204 名严重肥胖成年人在接受代谢手术程序后 1 年进行了随访（n = 121）。
我们使用三因素饮食问卷测量了进食行为，并使用线性混合模型比较了三组程序内和之间的进食行为。我们遵循 STROBE 清单报告观察性研究。
组内，在抑制和饥饿方面有统计学上显著的增加，而在抑制方面有统计学上显著的减少。在组间，我们观察到与带术相关的抑制差异。手术后一年，体重或体重指数没有任何组之间的显著差异。抑制是唯一与体重、体重指数和体重减轻百分比相关的进食行为。
接受三种代谢手术之一的严重肥胖成年人的进食行为与术后 1 年的进食行为变化有关。抑制是唯一与体重相关的进食行为。
无论手术程序如何，我们发现参与者在手术后 1 年内的抑制作用显著增加，而抑制作用和饥饿感显著降低。尽管带组的抑制作用明显降低，但与其他组相比，术后这种行为更为明显。尽管饥饿感的减少显示出最大的变化，但它与体重结果无关。这对于支持肥胖手术患者的护士来说是相关的临床知识。
