Night eating patterns and chronotypes: a correlation with binge eating behaviors.
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.
