Objective: Eating behavior is affected by psychological and neurocognitive factors. However, little is known about this relationship in anxious patients. Our aim was to investigate the associations between impulsivity, inhibitory control, energy-dense food consumption, and body mass index (BMI) in women with generalized anxiety disorder (GAD). Methods: In this cross-sectional study, 51 adult females with GAD answered the Barratt Impulsiveness Scale (BIS-11) and participated in a go/no-go task using food images. Anthropometric measurements were evaluated. A food frequency questionnaire and a snack test were used to study eating behavior. Pearson correlation and multiple linear regression were performed to analyze the variables of interest, adjusted by age. Results: Impulsivity predicted intake of sugar (p = 0.016, 95%CI 0.67-6.05), total fat (p = 0.007, 95%CI 0.62-3.71), and saturated fat (p = 0.004, 95%CI 0.30-1.48). The snack test showed a positive correlation between presence of impulsivity and intake of biscuits (R = 0.296; p = 0.051). Response inhibition to food images in the go/no-go task paradigm did not predict BMI or food intake. Conclusion: Impulsivity was predictive of higher sugar and saturated fat intake in women diagnosed with GAD. Our findings add to the literature regarding the association between neuropsychological factors and food consumption in this specific population.

冲动会影响患有广泛性焦虑症的女性的食物摄入量

目的：饮食行为受心理和神经认知因素的影响。然而，人们对焦虑患者的这种关系知之甚少。我们的目的是调查患有广泛性焦虑症 (GAD) 的女性的冲动、抑制控制、高能量食物消耗和体重指数 (BMI) 之间的关联。方法：在这项横断面研究中，51 名患有 GAD 的成年女性回答了 Barratt 冲动量表 (BIS-11) 并使用食物图像参与了去/不去任务。评估了人体测量学测量值。使用食物频率问卷和零食测试来研究饮食行为。进行 Pearson 相关和多元线性回归以分析感兴趣的变量，并根据年龄进行调整。结果：冲动性预测糖摄入量 (p = 0.016, 95% CI 0.67-6.05)、总脂肪 (p = 0. 007, 95% CI 0.62-3.71) 和饱和脂肪 (p = 0.004, 95% CI 0.30-1.48)。零食测试显示冲动的存在与饼干的摄入量之间呈正相关（R = 0.296；p = 0.051）。在去/不去任务范式中对食物图像的反应抑制不能预测 BMI 或食物摄入量。结论：冲动性可预测诊断为 GAD 的女性摄入较高的糖分和饱和脂肪。我们的研究结果增加了有关该特定人群中神经心理因素与食物消费之间关联的文献。冲动性可预测诊断为 GAD 的女性摄入较高的糖分和饱和脂肪。我们的研究结果增加了有关该特定人群中神经心理因素与食物消费之间关联的文献。冲动性可预测诊断为 GAD 的女性摄入较高的糖分和饱和脂肪。我们的研究结果增加了有关该特定人群中神经心理因素与食物消耗之间关联的文献。
