Mental health and sleep quality: are intuitive eating, hedonic hunger and diet quality, determinants? a cross-sectional study

Abstract

Background
Intuitive eating may predict better psychological and behavioral health. Intuitive eating, hedonic hunger, and diet quality may affect
individuals’ mental health and sleep quality.
Methods
Descriptive cross-sectional study developed with an online questionnaire for randomly selected volunteers (n=351) aged 19-64 years.
Hedonic hunger status was evaluated by Power of Food Scale (PFS), intuitive eating by Intuitive Eating Scale-2 (IES-2), mental health
status by Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) and sleep quality by Pittsburgh Sleep Quality Index (PSQI). Food
consumption records were taken to evaluate individuals’ dietary quality, using Healthy Eating Index (HEI)-2015.
Results
It was found that 50.7% of the participants exhibited intuitive eating behavior, while 65.0% experienced hedonic hunger. When the diet quality was examined, it was found that 65.2% of the participants had poor diet quality, while 33.6% needed to improve their
diet quality. Sleep quality and mental health status of individuals exhibiting intuitive eating behavior were significantly better (p<0.05).
Diet quality was not associated with mental health, intuitive eating, hedonic hunger and sleep quality scores (p>0.05). While there
was a weak negative correlation between intuitive eating and PSQI score (r=-0.160, p<0.05), while a positive correlation was found
between hedonic hunger and PSQI score (r=0.286, p<0.05). Intuitive eating was associated with better sleep quality, as lower PSQI
scores indicate better sleep quality. Intuitive eating was also associated with better mental health (r=0.339, p<0.05).
Conclusion
This study reveals that intuitive eating behavior is associated with better sleep quality and mental health, while hedonic hunger
behavior is associated with poor sleep quality.
