To date, studies on the role of eating traits in weight loss success have only included obese people without type 2 diabetes mellitus (T2DM), thereby disregarding negative effects of T2DM-related metabolic changes. Our aim was to assess the association between eating traits and weight change after a lifestyle intervention in people with T2DM.
For the current study, we reexamined data from a six-month intervention in 120 participants. We determined eating traits at baseline, using the DEBQ, which were used to produce three groups: unsuccessful dietary restrained (high restraint, high emotional/external eating scores), successful dietary restrained (high restraint, low emotional/external eating scores), and reference (low restraint, high or low emotional/external eating scores). Linear regression was used to study the association between the eating trait groups and weight changes after six months, while correcting for possible confounders.
On average, the weight loss success was limited, with a third of the participants being weight stable, a third losing weight > -1 kg (average loss -2.6 ± 1.9 kg), and a third gaining weight > +1 kg (average gain +3.3 ± 1.9 kg). When compared to the reference group, the unsuccessful dietary restrained gained weight during the intervention (beta = 1.2 kg, confidence interval (CI)% = 0.1; 2). No significant change was observed in the succesful dietary restrained group.
The eating trait of being unsuccessfully dietary restrained is associated with weight-loss failure after a six-month lifestyle intervention in people with T2DM.
迄今为止，关于饮食特征在减肥成功中的作用的研究仅包括肥胖且无 2 型糖尿病（T2DM）的人群，因此忽略了 T2DM 相关代谢变化的负面影响。我们的目的是评估 T2DM 患者在生活方式干预后饮食特征与体重变化之间的关系。
为了进行当前研究，我们重新分析了 120 名参与者进行的为期 6 个月的干预研究的数据。我们在基线时使用 DEBQ 确定了饮食特征，该问卷将参与者分为 3 组：不成功的饮食限制（高限制、高情绪/外部进食评分）、成功的饮食限制（高限制、低情绪/外部进食评分）和参照组（低限制、高或低情绪/外部进食评分）。采用线性回归分析了 6 个月后饮食特征与体重变化之间的关系，并校正了可能的混杂因素。
平均而言，减肥效果有限，三分之一的参与者体重稳定，三分之一的参与者体重减轻超过-1kg（平均减轻-2.6±1.9kg），三分之一的参与者体重增加超过+1kg（平均增加+3.3±1.9kg）。与参照组相比，不成功的饮食限制者在干预期间体重增加（β=1.2kg，置信区间（CI）%=0.1；2）。成功的饮食限制组体重无明显变化。
在 T2DM 患者进行为期 6 个月的生活方式干预后，饮食特征中不成功的饮食限制与减肥失败有关。
