Abstract
OBJECTIVES
Sedentary behavior has gradually increased and has become a public health problem. Therefore, this study investigated trends in weekday leisure-time sedentary behaviors, as well as characteristic socio-demographic and lifestyle correlates in Korean adults.
METHODS We analyzed data from 914,946 adults aged ≥19 years who participated in the Korea Community Health Survey (2011, 2013, 2015, and 2017). Leisure-time sedentary behavior was categorized as a binary variable (<4 and ≥4 hr/day). Multivariable regression analysis was used to model the prevalence of sedentary behavior and estimate odds ratios.
RESULTS The prevalence of leisure-time sedentary behavior decreased from 15.2% to 14.4% in men and from 16.6% to 16.0% in women between 2011 and 2017, respectively. However, a significant increase was observed in subjects with an education lower than high school in both genders (β coefficient=0.12 for men and 0.08 for women, p for trend <0.001). Women in the lowest household income level (β coefficient=0.08, p for trend=0.001) and with poor subjective health status (β coefficient=0.05, p for trend=0.013) showed an increasing trend. Other factors associated with sedentary behavior were age, education level, body mass index, household income, walking activity, perceived stress level, and subjective health status in both genders.
CONCLUSIONS Identifying the secular trends and correlates of sedentary behavior by gender and associated factors will provide empirical evidence for developing public health campaigns and promotion programs to reduce sedentary behavior in Koreans.

Summary
Korean summary
본 연구는 지역사회건강조사에서 2011년부터 2017년까지 격년으로 수집된 성인의 좌식행동에 대한 시간적 추세와 관련 요인에 대해 분석한 시계열 단면연구이다. 분석결과, 주중 여가시간에 4시간 이상 앉아 있는 경우는 남성의 경우 15.2%에서 14.4%로, 여성의 경우 16.6%에서 16.0%로 감소되었다. 그러나, 남녀 모두에서 노인인 경우, 중졸 이하의 학력을 가진 경우, 소득수준이 월 100만원 미만인 경우, 주관적 건강상태가 부정적인 경우 좌식행동이 증가하였다. 따라서, 본 연구에서 나타난 좌식행동 관련 요인을 가진 대상자를 목표집단으로 한 건강증진 및 공중보건 캠페인이 개발 및 실행될 필요가 있다.
Key Message
This study is a serial cross-sectional study analyzing the temporal trend and related factors of sedentary behavior of adults using KCHS collected biennially from 2011 to 2017. The prevalence of leisure-time sedentary behavior decreased from 15.2% to 14.4% in men and from 16.6% to 16.0% in women, respectively. However, elderly, subjects with an education lower than high school, with the lowest household income level, and with poor subjective health status showed an increasing sedentary behavior trend. These findings suggest that health promotion and public health campaigns are need to reduce the prevalence of sedentary behavior in population with related factors.

Abstract
OBJECTIVES
We examined the associations of individual and regional-level perceived stress and depression with health-related quality of life (HRQOL) in Korean adults.
METHODS We used data from the 2017 Korea Community Health Survey, which included 216,713 adults living within 254 municipal districts. As individual-level independent variables, perceived stress (higher vs. lower) and depression (Patient Health Questionnaire-9 ≥10) were defined. Regional-level age-adjusted rates of perceived stress (%) and depression (%) were created for 254 municipal districts and categorized into quartiles to generate regional levels of stress and depression. HRQOL was defined as the individual-level EuroQol 5-dimensional index×100. A multilevel analysis was performed to identify the relationship between individual or regional-level independent variables and individual HRQOL.
RESULTS In the null model, the proportions of individual variation in the HRQOL explained by region were 1.7% and 2.7% for men and women, respectively. When adjusted with all individual-level variables, regional stress and depression, as well as individual-level perceived stress and depression, were significantly related to HRQOL for both genders. In the full model including all variables, the decrease in HRQOL from the first to the fourth quartile group of regional stress was greater in women (-1.09; 95% confidence interval [CI], -1.87 to -0.31) than in men (-0.65; 95% CI, -1.04 to -0.26).
CONCLUSIONS Our results suggest that regional-level perceived stress and depression, as well as individual-level perceived stress and depression, are inversely associated with individual HRQOL.

시군구 단위 스트레스 인지율과 우울 유병률이 개인 단위 건강관련 삶의 질 수준과 연관성을 갖는지 파악하고자 지역사회건강조사 자료를 이용하여 다수준 분석을 수행하였다. 개인 수준에서 인지된 스트레스와 우울은 건강관련 삶의 질 감소와 관련이 있었다. 스트레스와 우울 수준이 높은 시군구일수록 개인의 건강관련 삶의 질은 낮아지는 관계를 보였는데, 이는 남성보다는 여성에서 더 저명하였다.
Key Message
This study examined the associations of regional-level perceived stress and depression with individual HRQOL measured in terms of the EQ-5D using a multilevel model. Individual-level perceived stress and depression were significantly related to individual HRQOL. Regional stress and depression were also significant factors and both had greater negative impacts on HRQOL among women than among men.
