Can night eating syndrome and sleep quality have strong relations with quality of life in early adulthood?

Abstract

Sleeping disorders can impair sleeping efficiency and lead to eating disorders and night eating syndrome. Eating disorders and night eating syndrome can be considered as factors that reduce the quality of life. The aim of the study was to investigate the effects of eating and sleeping disorders, and night eating syndrome, on quality of life. Material and methods. The sample of the descriptive, cross-sectional research was comprised of 846 students, who were studying at Uskudar University in the 2020/2021 academic year, accepted to participate in the study and provided complete information. Data was collected with a diagnostic form, a SCOFF Eating Disorders Scale form, a Night Eating Questionnaire (NEQ) form, a Pittsburgh Sleep Quality Index (PSQI) form, and a World Health Organization Quality of Life Short Form (WHOQOL-BREF-TR) together, all were created in Google Forms and applied online. Research data was evaluated with IBM SPSS v® software. Results. A total of 846 university students, consisting of 712 (84.2%) females and 134 (15.8%) males participated in the study. The mean age of the participants was 21.4±3.1 years, and the mean body mass index was 22.5±8.0 kg/m2. Eating disorders risk was found as 38.4%, night eating syndrome risk as 67.7% and all participants had poor sleep quality. WHOQOL-BREF-TR scale's total and all sub-dimension mean scores were found to be lower in students with a risk of eating disorders and night eating syndrome, compared to students without it (p<0.001). A statistically significant negative correlation was found between the PSQI total score and WHOQOL-BREF-TR scale's total and all sub-dimension scores of the participants (p<0.001). Conclusion. Students with a risk of night eating syndrome have interrupted sleep due to desire to eat at night, which is another factor that reduces sleep quality. For healthy generations, sleep and nutrition habits should be carefully examined and appropriate treatment methods should be applied by determining the faulty attitudes of individuals in nutrition, eating and sleeping disorders.
