Evaluation of the relationship between sleep quality, diet quality and appetite in adult individuals

Aim: In this study, it was aimed to investigate the relationship between sleep quality, diet quality and emotional appetite in adults. Materials and Methods: This study was conducted with 50 participants over the age of 18 who applied to a private psychological counseling center in Bursa, did not use any sleep-enhancing or regulating drugs and supplements. Sleep quality was assessed through Pittsburgh Sleep Quality Index (PSQI), dietary quality through Healthy Eating Index 2015 (HEI 2015), emotional appetite through Emotional Appetite Questionnaire (EMAQ), and dietary habits through Three Factor Eating Questionnaire (TFEQ). Body composition and anthropometric measurements were performed in accordance with predetermined standards. Results: While 52% of the participants had good sleep quality, 48% of them had poor sleep quality. The mean total PUKI score was 6.16±3.11. There was no significant difference in diet quality score between the groups with good sleep quality and the group with poor sleep quality (p>0.05). Only the whole grain score, which is one of the diet quality factors, was negatively associated with the PSQI total sleep quality score. Whole grain score was also positively correlated with EMAQ positive status and total scores. While there was a significant positive correlation between the total PSQI score and the amount of caffeine consumed (p<0.05), there was no significant correlation between energy and other nutrients (p>0.05). There was no significant relationship between sleep quality groups and total sleep quality score and emotional appetite (p>0.05). Conclusion: Determination and evaluation of diet quality and sleep quality helps to unravel the complex relationship between sleep and nutrition. Nutritional behaviors and appetite both indirectly and directly affect sleep quality and diet quality, so more research is needed in these areas.
