Association between chronotype and the constructs of the Three-Factor-Eating-Questionnaire

The aim of this study was to explore associations between chronotype and the Three-Factor-Eating-Questionnaire. We found a positive association between morningness and dietary restraint and negative correlations between morningness and disinhibition and perceived hunger. Further, there was an association between morningness and flexible control. BMI tended to be negatively associated with morningness and correlated with disinhibition and with the sub-scale RC7. No association was found between BMI and cognitive restraint, hunger and flexible control. Also, no relationships existed between sleep length on weekdays or on weekends and BMI OF eating.
