Background and Aim: Our primary objective is to examine the variance in chronotype, night-eating patterns, and sleep quality in patients with biop-sy-proven metabolic dysfunction-associated steatotic liver disease. In addi-tion, we aim to establish a correlation between these variables and the sever-ity of the disease and fibrosis.
Material and Methods: Patients who were following up with biopsy-prov-en metabolic dysfunction associated steatotic liver disease (MASLD) were included in the study. Histologically severe disease is characterized by a Ste-atosis, Activity, and Fibrosis activity score of ≥3 or the presence of advanced fibrosis (≥F3). Participants who met the inclusion criteria were given the Morningness and Evening Questionnaire (MEQ), the Pittsburgh Sleep Quali-ty Index, and the Night Eating Questionnaire to complete.
Results: A total of 93 patients were included in this study. According to the MEQ, 48 patients were morning type (51.6%), and 42 (45.2%) were neither type. Sleep quality was determined to be inferior in the non-morningness group (p=0.002). A significantly higher proportion of patients with nocturnal eating syndrome had a non-morningness chronotype preference (n=22, 23.7%), com-pared to those with a morningness chronotype (n=9, 9.7%) (p=0.001). In the multivariate analysis, both age and poor sleep quality had significant impacts on advanced fibrosis, with odds ratios of 1.11 and 3.81, respectively.
Conclusion: Despite the non-morningness chronotype demonstrating poorer sleep quality and a higher prevalence of night-eating behavior, our findings revealed no statistically significant differences in terms of sleep quality, noc-turnal eating habits, or chronotype preferences among patients with varying degrees of MASLD severity. On the other hand, advanced fibrosis was sig-nificantly impacted by poor sleep quality.
