How does the weekend catch-up sleep ratio affect the health and lifestyle of Korean adults? An age- and sex- matched study

The purpose of this study was to investigate the association between various levels of physical activity, self-perception, cardiometabolic risk factors, and weekend catch-up sleep ratio (CSR). Using raw data from the Korea National Health and Nutrition Examination Survey 2018 – 2021, all participants were divided into three groups (< 1.0, 1.0 ≤ CSR < 1.5, or ≥ 1.5) by CSR, which is the value calculated by dividing weekend sleep time by weekday sleep time. After matching age and sex, 2,484 Korean adults were selected as study participants. Descriptive statistics, chi-square test, ANOVA, and multinomial logistic regression analysis were performed to analyze the data. The results showed a significant association between weekend CSR and socioeconomic status, physical activity, self-perception levels, and cardiometabolic risk factors. Specifically, compared to the reference group (1 ≤ CSR < 1.5), those with a CSR < 1 were 2.42 times more likely to live in a single-family house (O..., This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) during 2018 – 2021. The KNHANES is a comprehensive national survey implemented across South Korea. Its primary objective is to consistently accumulate data annually encompassing various elements, including sociodemographic indicators, economic status, and health-related characteristics and behaviors across all age demographics. Since 2007, this body of data has undergone review and received an annual endorsement by the Research Ethics Review Committee from the Korea Centers for Disease Control and Prevention Agency (KDCA). The KNHANES data is an open-access resource for scholars, enabling further exploratory analysis and research in numerous fields.
The KNHANES for 2018 – 2021 was conducted with 30,551 respondents. However, 5,616 individuals under 20 years were excluded from the data to align with the research parameters. In addition, participants who did not respond to the cri..., , # Korea National Health and Nutrition Examination Survey 2018 \~ 2021
