The association between night eating syndrome and health-related quality of life in Korean adults: a nationwide study

Abstract

Purpose Quality of life may be influenced by the presence of eating disorders. This study investigated the association between night eating syndrome (NES) and health-related quality of life in the general population. Methods Data were from the 2019 Korea Community Health Survey. The presence of NES was determined using the Night Eating Questionnaire. Health-related quality of life was measured using the 3-level EuroQoL-5 Dimension Index. Multivariable linear regression analyses assessed the association between NES and health-related quality of life. Subgroup analyses were performed based on daily sleep duration. Results A total of 34,434 individuals aged 19 years or older were included in the study population. Participants with NES (β = − 4.85, p < 0.001) reported poorer health-related quality of life scores than those without NES. Decreases in health-related quality of life scores among those with NES were greatest in those who slept over 8 h daily (β = − 12.03, p = 0.004), followed by those who slept less than 6 h (β = − 5.90, p = 0.006) and participants who slept between 6 and 8 h (β = − 3.40, p = 0.026) daily. Conclusion Individuals with NES were more likely to have a lower health-related quality of life than those without NES. These findings highlight the potential importance of considering NES in investigating the health-related quality of life. Level of evidence Level III, well-designed case–control analytic studies.

A Scoping Review on the Association between Night Eating Syndrome and Physical Health, Health-Related Quality of Life, Sleep and Weight Status in Adults

“…Upon reviewing the abstracts of articles obtained through a search on Medline (OVID) and SCOPUS, five additional relevant articles were included. After the screening process, 30 studies [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ] assessing NES met the inclusion criteria and were thus included in this scoping review. The need for further research into NES within adult populations is reiterated through the limited number of relevant studies yielded through this search.…”

“…As shown in Table 1 , only five studies investigated NES in a representative participant sample [ 26 , 27 , 32 , 37 , 44 ], whilst fourteen studies reported on university students [ 17 , 19 , 24 , 25 , 33 , 34 , 35 , 39 , 40 , 41 , 42 , 43 , 45 , 46 ] and ten studies reported on patients within outpatient clinics [ 18 , 20 , 21 , 22 , 23 , 28 , 29 , 30 , 36 , 38 ]. Most studies [ 17 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 28 , 29 , 30 , 32 , 34 , 36 , 37 , 39 , 42 , 43 , 44 , 45 ,…”

“…Only six studies [ 17 , 30 , 39 , 43 , 44 , 46 ] explored the impact of NES on physical activity, with four studies [ 30 , 39 , 44 , 46 ] reporting a significant association and two studies [ 17 , 43 ] reporting no significant relationship. Levels of physical activity were assessed via the International Physical Activity Questionnaire—Short-form (IPAQ-S) [ 53 ], World Health Organization Quality of Life Turkish Short Form (WHOQOL-BREF-TR) [ 54 ] and HRQOL scores [ 6 ].…”

“…Levels of physical activity were assessed via the International Physical Activity Questionnaire—Short-form (IPAQ-S) [ 53 ], World Health Organization Quality of Life Turkish Short Form (WHOQOL-BREF-TR) [ 54 ] and HRQOL scores [ 6 ]. Two of the studies which utilised the WHOQOL-BREF-TR and HRQOL did not specifically discuss the physical domains [ 44 , 46 ].…”

“…This scoping review investigated the associations between NES and Body Mass Index (BMI; kg/m 2 ), physical health and sleep conditions. Thirty studies were identified that reported on associations between physical health problems and NES over the past decade [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. Whilst there were inconsistencies in representative and larger-sample studies, NES appeared to be associated with higher BMI, less physical activity and poorer sleep quality.…”
