Background

Interoception refers to the process of identifying and listening to internal bodily signals, which may be a modifiable determinant of appetite regulation and weight gain. The objective was to examine whether the extent to which self-reported interoception is associated with higher BMI is explained by eating behavior traits.

Methods

UK adults (N = 1181, 49% female, 53% with overweight/obesity) completed validated self-report measures of interoception, habitual tendencies to eat in response to satiety signals (intuitive eating), emotional over-eating and other eating traits.

Results

Poorer self-reported ability to detect interoceptive signals (deficits in interoceptive accuracy) was predictive of higher BMI (r = - 0.07 (95% CI -0.13; -0.01), p < .05). In parallel mediation analyses, participants with poorer interoceptive accuracy were significantly less likely to report considering satiety signals when eating and this explained the cross-sectional association between interoceptive accuracy and higher BMI. There was also some evidence that participants with poorer interoceptive accuracy were more likely to report emotional overeating and this also in part explained why interoceptive accuracy was predictive of higher BMI.

Conclusions

Deficits in interoception may decrease the likelihood that satiety signals are integrated into eating behaviour related decision making and in doing so contribute to higher BMI.

背景

互感是指识别和聆听内部身体信号的过程,这可能是食欲调节和体重增加的可改变决定因素。目的是检查饮食行为特征是否可以解释自我报告的自我感知与较高的BMI相关的程度。

方法

英国成年人(N  = 1181,49%的女性,53%的超重/肥胖)完成了自我报告的自我感知测评,包括自我感知,对饱食感信号的直觉饮食习惯(直觉饮食),情绪饮食过量和其他饮食特征。

结果

自我报告的检测感知信号的能力较差(感知准确性的缺陷)预示着较高的BMI(r  =-0.07(95%CI -0.13; -0.01),p <.05)。在平行调解分析中,具有较弱的接受感知准确性的参与者进食时考虑饱腹感信号的可能性大大降低,这解释了接受感知准确性与较高BMI之间的横断面关联。也有一些证据表明,具有较差的感知力的参与者更有可能报告情绪暴饮暴食,这也部分解释了为何感知力的准确性可以预测较高的BMI。

结论

互感障碍可能会降低饱食感信号被整合到与饮食行为相关的决策中的可能性,并因此而导致较高的BMI。
