Abstract
OBJECTIVES
This study investigated recent trends in the prevalence of obesity among Korean adolescents and explored socioeconomic disparities in obesity.
METHODS
This study used annual self-reported data on height, weight, and socioeconomic information from the Korea Youth Risk Behavior Web-based Survey from 2006 to 2020. With a 95.8% response rate, the sample consisted of 818,210 adolescents. Obesity prevalence was calculated according to 4 socioeconomic indicators (household income, father’s educational attainment, mother’s educational attainment, and urbanicity). Socioeconomic inequality was quantified using the relative index of inequality (RII).
RESULTS
The overall prevalence of obesity increased, doubling from 5.9% in 2006 to 11.7% in 2020. Boys and high school students showed a higher prevalence. The RIIs in household income and parental educational attainments significantly increased with time, indicating a growing inequality in obesity. Socioeconomic disadvantages had a greater influence on obesity among girls. The most recent RII values for boys were 1.25 for income, 1.79 for the father’s education, and 1.45 for the mother’s education, whereas the corresponding values for girls were 2.49, 3.17, and 2.62, respectively.
CONCLUSIONS
These findings highlight growing inequalities in adolescent obesity according to household income and parental educational attainments, especially for girls and middle schoolers.
Summary
Korean summary
2006년부터 2020년까지 청소년 비만의 유병은 증가 추세에 있을 뿐 아니라, 가정의 경제상태, 부모의 학력수준에 따른 비만의 위험 격차도 점점 심해지는 추세를 보였다. 특히, 남학생과 고등학생의 비만 유병률이 높게 나타났으나, 사회경제적 지표에 따른 비만의 불평등 격차는 여학생과 중학생에서 높게 나타났다.
Key Message
Not only the prevalence but also socioeconomic inequality in adolescent obesity increased between 2006 and 2020. The potential impact of socioeconomic disparity on obesity was greater in girls and middle school students than their counterparts.

Abstract
OBJECTIVES
Socioeconomic disparities have been reported as major risk factors contributing to the spread of coronavirus disease 2019 (COVID-19) at the community level. We conducted an epidemiological study on COVID-19 incidence risk using area-based deprivation indices (DIs) reflecting the characteristics of the susceptible population.
METHODS
A database of the confirmed COVID-19 cases in 8 metropolitan cities in Korea from January 20, 2020 to December 31, 2021 was combined with area-based DI scores and standardized prevalence rates of diabetes and hypertension from the Korean Community Health Survey. Relative risk (RR) levels were estimated using a generalized linear model with a Poisson distribution by age group.
RESULTS
The risk of COVID-19 incidence generally increased with increasing age, especially in patients aged ≥75 years. The RR of COVID-19 incidence per interquartile range increment of the composite deprivation index (composite DI) was 1.54 (95% confidence interval [CI], 1.34 to 1.70). Notably, in the first wave, the risk of COVID-19 incidence was approximately 3 times higher in the region with the lowest socioeconomic status than in the region with the highest status (RR, 3.08; 95% CI, 2.42 to 3.78 based on the the composite DI and RR, 3.13; 95% CI, 2.53 to 3.83 based on the social deprivation index).
CONCLUSIONS
This study provides scientific evidence that socioeconomic deprivation is an important risk factor for the spread of COVID-19. This finding suggests that a mid-term to long-term strategy is needed to protect susceptible populations and reduce the burden of COVID-19 in the community.
Summary
Korean summary
한국의 COVID-19 발생 위험은 지역박탈수준이 높은 지역에서 증가하였고, 특히 유행 초기 75세이상 연령층에서 뚜렷하게 증가하는 것으로 나타났다. 따라서 지역사회수준에서 사회경제적 여건을 고려하여 취약집단에서의 발생위험을 감소시키기 위해 중장기 전략을 세워야 한다는 것을 시사한다.
Key Message
There is a need to develop long-term strategies to reduce the risk of COVID-19 outbreaks in vulnerable populations in areas with poor socioeconomic conditions
