Abstract

Abstract Background Sleep health-related indicators are deeply associated with social status and income level. Differences in sleep duration and quality in the USA varied based on race, ethnicity, and socioeconomic status. National studies or studies focusing on the residents of metropolitan areas may only reflect a part of Korea. Objective We aimed to explore the relationship between sleep health and lifestyles, as well as socioeconomic status in Gangwon Province. Methods The present study utilized raw data from the 2018 Korean Community Health Survey (KCHS) conducted by the Korean Centers for Disease Control and Prevention. The KCHS is a cross-sectional survey with a study population drawn from multistage, stratified area probability samples of civilian, non-institutionalized Korean households in Gangwon Province. Using data from the KCHS of 1,296,218 Korean individuals residing in Gangwon Province (648,888 men and 647,330 women), we conducted cross-sectional analysis with sex subgroup analysis. Sleep duration was classified into three groups—short ( 9 hours). The Pittsburgh Sleep Quality Index (PSQI) score was used to classify sleep quality into two groups—poor (PSQI > 5) and good sleep (PSQI ≤ 5). Results Poor sleep quality was associated with lower income, low education level, irregular breakfast patterns, old age (> 50), higher subjective stress, diabetes, and depression. Conclusion Sleep health is closely related to the socioeconomic status among Gangwon Province residents.
