这项横断面研究考察了早晨/晚上维度与饮食模式之间的关联。该样本由在营养诊所筛查的 100 名受试者组成，其中 77% 为女性；平均年龄为 39.5 (+/-11.7) 岁； 66% 的人超重。早晚问卷 (MEQ) 总分与暴食量表 (BES) 和夜间进食问卷 (NEQ) 之间存在显着的双变量相关性。 NEQ 和 BES 也显着相关。体重指数 (BMI) 与 NEQ 和 BES 相关，但它不是一个混杂变量，因为 MEQ 和 BMI 之间没有发现关联。为了控制变量之间潜在的多重共线性效应，我们还使用了多元回归分析，其中调整了相关系数的值。只有 BES 与 MEQ 保持统计相关性。总之，这些结果表明，生物钟研究可能是描述饮食失调特征时需要考虑的一个重要问题。这项研究有助于更详细地检查暴食症（BED）和夜间进食综合症（NES）患者的昼夜节律摄入模式，以帮助辨别这些重要的疾病分类学问题。 (C) 2012 Elsevier Ireland Ltd. 保留所有权利。
This cross-sectional study examined the association between the morningness/eveningness dimension and eating patterns. The sample consists of 100 subjects who were screened at a nutrition clinic and was composed of 77% women; mean age was 39.5 (+/-11.7) years; and 66% were overweight. Significant bivariate correlations were found between the Morningness-Eveningness Questionnaire (MEQ) total score and the Binge Eating Scale (BES) and the Night Eating Questionnaire (NEQ). The NEQ and BES were also significantly correlated. Body mass index (BMI) was correlated with the NEQ and BES, but it was not a confounding variable as no associations were found between the MEQ and BMI. To control for potential multicollinearity effects among variables, we also used multivariate regression analysis in which the values of the correlation coefficients were adjusted. Only the BES remained statistically associated with the MEQ. In conclusion, these results suggest that the study of chronotype may be an important issue to be considered when characterizing disordered eating. This study serves as an impetus for examining circadian intake patterns in more detail between those with binge eating disorder (BED) and night eating syndrome (NES) to help discern these important nosological questions.
