0766 Current Sleep Hygiene Status in Non-clinical Population in Korea

Abstract Introduction This study examines the difference in sleep hygiene status according to age and sex and the relationship between sleep hygiene and insomnia in the non-clinical Korean population using the Sleep Hygiene Practice Scale in Korean (SHPS-K), validated through this study. Methods We recruited non-clinical adults (Aged 18-65) without a history of neurologic, psychiatric, or medical disorders and diagnosed sleep disorders. An online survey was done using SHPS-K, the Pittsburgh Sleep Quality Index (PSQI-K), Insomnia Severity Index (ISI-K), and Epworth Sleepiness Scale (KESS). The first survey enrolled 484 participants (242 women, mean age of 43.8 years), among whom 322 completed the second survey. SHPS-K was compared between each age group, sex, and group with or without insomnia symptoms (ISIS-K 15). Using receiver operating characteristic analysis in different age groups, we also determined the cutoff values that could identify poor sleepers with insomnia symptoms (PSQI-K > 5 and ISI-K 15). Results The average total SHPS-K score was 71.2, with no sex difference. Mean ISI-K, PSQI, and ESS were not different between sex and age groups. The older participants had lower SHPS-K than the younger groups, with a significant trend for ages ( =-3.01, p< 0.001). This trend was significant in both men and women. Men had poorer eating and drinking behaviors among the four domains, and women had poorer sleep scheduling and timing behaviors. Young adults with insomnia symptoms showed the highest SHPS-K than other age groups with insomnia (p < 0.001). A cutoff value of 76, 74, and 66 identified poor sleepers with insomnia (area under the curve = 0.818, 0.837, 0.849) in young, middle-aged, and older adults, respectively. Conclusion This study showed that sleep-disturbing behaviors were different between age groups and sex. The group with insomnia symptoms showed worse sleep hygiene practices. Furthermore, young adults had significantly worse sleep hygiene than middle-aged or older adults. Sleep hygiene education could contribute differentially to improving sleep quality in non-clinical populations. Support (if any)
