Abstract
OBJECTIVES
This study aimed to describe trends in health behaviours between 2011 and 2020 and compare the changes in these behaviours between the 2020 COVID-19 pandemic and previous periods according to socio-demographic variables.
METHODS
This study used data from the 2011 to 2020 Korea National Health and Nutrition Examination Survey. Current cigarette smoking, high-risk drinking, and inadequate physical activity levels were used as health behaviour indicators. The age-standardized prevalence, differences in prevalence between the periods, and the annual percentage change (APC) were calculated.
RESULTS
Current cigarette smoking showed a decreasing trend (APC, -2.6), high-risk drinking remained unchanged, and inadequate physical activity levels increased (APC, 3.5) during 2011-2020. There were significant differences in high-risk drinking (3.1%p; 95% confidence interval [CI], 0.3 to 5.9) and inadequate physical activity levels (4.3%p; 95% CI, 0.4 to 8.1) between 2019 and 2020 in men. Among men, increased high-risk drinking was found in those aged 40-49 years, non-single households, urban residents, and the middle and highest income groups between 2019 and 2020. The low educational group and manual workers among men aged 30-59 years also showed an increased proportion of high-risk drinking. Inadequate physical activity levels also increased among men between 2019 and 2020 in those aged 30-39 years, non-single households, urban residents, and the upper-middle-income group.
CONCLUSIONS
In the first year of the COVID-19 pandemic, Korean men’s high-risk drinking and inadequate physical activity levels increased. In addition to social efforts to reduce the spread of infectious diseases, active measures to positively change health behaviour are needed.
Summary
Korean summary
코로나 대유행 첫 해인 2020년, 한국 남성에서 고위험음주와 부적절한 신체 활동 수준이 증가하였다. 감염성 질환 대유행 시기, 확산을 차단하기 위한 사회적 노력과 더불어 건강행태에 부정적인 여파가 미치지 않도록 적극적인 대책이 필요함을 시사한다.
Key Message
In the first year of the COVID-19 pandemic, Korean men’s high-risk drinking and inadequate physical activity levels increased. Despite Korea's positive performance in various indicators during the COVID-19 pandemic, the socioeconomic and cultural effects of COVID-19 have affected people's health behaviour. In addition to social efforts to reduce the spread of infectious diseases, active measures to positively change health behaviour are needed.

Abstract
Objectives
This study aimed to examine the trends in total mortality between 1998 and 2020 and to compare the changes in a wide range of detailed causes of death between 2020 during the COVID-19 pandemic and the previous year in Korea.
Methods
We used registered population and mortality data for the years 1998–2020 obtained from Statistics Korea. The age-standardized all-cause mortality rate and the annual percent change between 1998 and 2020 were determined. The rate ratio and rate difference of the age-standardized mortality rate were calculated between 2019 and 2020, respectively.
Results
The age-standardized all-cause mortality rate in Korea has been on a downward trend since 1998, and the decline continued in 2020. In 2020, 950 people died from COVID-19, accounting for 0.3% of all deaths. Mortality was decreased for most causes of death; however, the number of deaths attributed to sepsis and aspiration pneumonia increased between 2019 and 2020 for both men and women. Age-specific mortality rates were decreased or stable between 2019 and 2020 for all age groups, except women aged 25-29. This increase was mainly attributed to an increase in suicide deaths.
Conclusions
This study shed light on the issues of sepsis and aspiration pneumonia despite the successful response to COVID-19 in Korea in 2020. The causes of death from sepsis and aspiration pneumonia should be identified and monitored. In addition, it is necessary to develop a proactive policy to address suicide among young people, especially young women.

Abstract
OBJECTIVES
To examine the income gaps associated with self-rated poor health at the district level in Korea and to identify the geographical correlations between self-rated poor health, life expectancy, and the associated income gaps.
METHODS
We analyzed data for 1,578,189 participants from the Community Health Survey of Korea collected between 2008 and 2014. The age-standardized prevalence of self-rated poor health and the associated income gaps were calculated. Previously released data on life expectancy and the associated income gaps were also used. We performed correlation and regression analyses for self-rated poor health, life expectancy, and associated income gaps.
RESULTS
Across 245 districts, the median prevalence of self-rated poor health was 15.7% (95% confidence interval [CI], 14.6 to 16.8%), with interquartile range (IQR) of 3.1 percentage points (%p). The median interquintile gaps in the prevalence of self-rated poor health was 11.1%p (95% CI, 8.1 to 14.5%p), with IQR of 3.6%p. Pro-rich inequalities in self-rated health were observed across all 245 districts of Korea. The correlation coefficients for the association between self-rated poor health and the associated income gaps, self-rated poor health and life expectancy, and income gaps associated with self-rated poor health and life expectancy were 0.59, 0.78 and 0.55 respectively.
CONCLUSIONS
Income gaps associated with self-rated poor health were evident across all districts in Korea. The magnitude of income gaps associated with self-rated poor health was larger in the districts with greater prevalence of self-rated poor health. A strong correlation between self-rated poor health and life expectancy was also observed.

본 연구에서는 우리나라 245개 시군구의 자가평가 불건강 유병률의 소득수준 간 격차 크기를 규명하고, 시군구 단위 자가평가 불건강 유병률과 그것의 소득수준 간 격차, 기대수명 및 기대수명의 소득수준 간 격차의 상관성에 대하여 분석하였다. 연구 결과, 우리나라 245개 모든 시군구에서 자가평가 불건강 유병률에서의 저소득층에 불리한 불평등이 존재하였다. 또한, 자가평가 불건강 유병률과 그것의 소득수준 간 격차, 기대수명 그리고 자가평가 불건강 유병률의 소득수준 간 격차와 기대수명의 소득수준 간 격차는 높은 상관성이 나타났다. 이 연구는 지방정부 차원에서 건강 형평성 현황에 관한 유의미한 정보를 제공하여 지역별 보건정책 수립의 근거로 활용할 수 있다는데 의의를 찾을 수 있다.
