The aim is to explore the links between ultra-processed food consumption, sleep quality, and chronotype in a healthy adult population.
Cross-sectional design with data from 200 adults
Used sQ-HPF to assess UPF consumption
Assessed sleep quality with the PSQI
Determined chronotype via the MEQ
Applied regression analyses to evaluate predictors
72% of participants reported high UPF consumption
74% had poor sleep quality
75.5% identified as having an intermediate chronotype
High UPF consumers had poorer sleep quality scores and lower chronotype scores
Age was inversely correlated with high UPF consumption
